Hi Zig Not exactly sure what it's from ? I know Nigel - oeb - bought it when he had the bike originally. It replaced another alloy tank that was on the bike. Maxton has been mentioned more than once, but I'm not sure if it is or isn't. I did have another identical tank at one point, plus Rob has one that looks the same on his project bike, so it's obviously not a one off - there are a few out there. Maybe someone who races or has raced may know ? 20210128_183528 by dusty miller, on Flickr It fits the aircooled frame perfectly at the front, but the rear uses a different mounting system to a standard aircooled tank, so an aircooled frame needs modding for the tank to fit.

I have the sister tank and it is a work of art in it's own right.

I now have a pair of standard 31k pipes to offer up, courtesy of Mouse - cheers mate I'm trying to work out if the standard pipes would fit - if they did, then a pair of Dave's/Alonze pipes should fit too, with a repositioned rear bracket. Trouble is, standard pipes are so bulky, they are difficult to offer up. Only had a quick look last night - will try and get some time over the weekend. I did measure across the Alonze downpipes on Mouse's 31k hybrid, and then across the downpipes on my 400's Allspeeds, and the measurements are close. The exhaust ports on the Pv are angled slightly inwards towards each other as on Lc's and Rd's, so that helps keep the downpipes away from the frame downtubes. I still haven't decided on stingers vs end cans. I want to keep the pipes looking as short as practically possible, and at least 6" can be saved if there are no cans. I'm not sure if the end tube needs to be longer to compensate - I've asked Dave that question ! But I am keen to get this sorted now, and the bike is now out of hibernation and has swapped places with the 400 for the time being, so it's my next job ! 20210128_204629 by dusty miller, on Flickr

Hi Dusty i had a similar problem as well. I put a 250 engine in my hybrid and it was not possible to fit a standard cigar or Allspeed type exhaust pipe. The pipe fittings on the bike are standard and as you say it was just the bulk of the end of the pipe and the height. All the other pipes like TSA's and Lomas fit. If you go Pea Shooter style you won't have the bulk problem at the end. A lot of these style pipes i've seen tend to be low slung.

Hi Tony Thats good to knowπ I know what you mean regards the low slung, pea shooter style pipes often seen on the early race bikes. I'm hoping the angle of the Alonze pipes keeps the kicked up look at the back. As with the rest of this build, it will be something a bit different with the pipes. I think the Alonze pipes for a Pv, in stainless, with pea shooter end pipes could look good. Otherwise an expensive faux pas !!

Hi Chris It's my favourite part of the bike ! I love the blocky, angular shape of it. It's the same with the aircooled "coffin" tanks - I always loved the shape of those. I've wanted an alloy Tz style tank on a bike for as long as I have had bikes, and I built the bike around the tank and seat combination. I often think about my next project, after this and the 400 are finished, and I would love to build another Cafe Racer style bike with an alloy tank and race seat as I love the style so much Dusty

I'm not a big fan of wire wheels to be honest Chris. I would never say never, and modern anodised rims can look awesome on certain bikes, but I do like alloy wheels, and multi spoke designs like the Mt09 style look great, and maybe something I would consider next time. I think the combination of a Tz style tank, seat and wheels may raise the expectation that the bike should be a proper replica, and I never planned to build a replica, due to expense, and the fact that there are lots of very nice replicas out there already. I also like to be free of rules, and use whatever I like, or already have. Not so much a Hybrid, more a "Hybritza" !! Dusty

Very good Dusty, we should be free to do our own thing when it comes to hybrids. I also like those multi spoke rims and I do love the look of spoked wheels but not sure I would ever use them myself.

I'm a big fan of "each to their own", and as I've said many times before, just build what you want. You are funding it, so you get to choose ! And if peeps like it great, if not, so what ? If someone gets an idea they can use, or solve a problem by learning from you, then that's great. We made our bikes "specials" when we were kids, and we still do now, we just call them Hybrids instead Spokeys can look awesome - Steve Midlifecrisis did a stunning Pv with spoked wheels - I would happily love and cherish a bike as lovely as that and the wheels really set it off, so I'm not a hater - just never planned a bike build with spoked wheels. I had the wheels and forks for this build already, so that was a major reason for using them. Plus I think the RWU forks suit this build better than USD forks, and I happen to really like Rgv wheels If we all liked the same thing, it would get boring very quickly ! Dusty

When i was 18 i had a AC rd250 (with 350 barrels) with a bare alloy TZ tank, TZ "style" fairing and single seat in yellow, looked fantastic until a fooking taxi driver did a U turn in front of me and the clip on put a big dint in the tank Repaired it but had to paint the tank, ended up Marlboro colours before i sold it for a 350LC....

Borrowed a different set of exhausts off Mouse today (thanks again mate ), in my quest to try and get the "look" for the pipes on this build. These are Mouse's old Mark Dent pipes from his 31k hybrid, and actually much nearer to what I will end up with. I've measured these from a given point on the engine, and compared that to the same measurements on Mouse's 31k fitted with Mutts' Alonze pipes. The Dent pipes are very fat in the mid section which isn't ideal for fit, whereas Mutt's are more forgiving, shape wise. Dave pointed out that the stingers would need to be 200mm minimum if I went without cans - anything shorter would be just too loud ! My main aim is to keep the pipes looking as short as possible - I really dont want pipes sticking out past the seat unit as I think it would look odd. I think the Pv pipes will fit between the frame down tubes though, going by measurements and trial fits, and I'm hopeful there are no obstacles under the frame to interrupt the run under the engine. If the rear bracket is left loose, that can be welded on by my mobile welding guy which will help. First pic is without a can to give the look of a stinger/peashooter, although the stinger would need to be longer; 20210203_170024 by dusty miller, on Flickr The next pic is with a paper 6" can to give an idea of length - again it would be slightly further back due to the different design of Dave's pipes; 20210203_173314 by dusty miller, on Flickr If I can keep the pipe roughly that length with the can fitted, I think it would look "right", and save any issues with Plod/MOT testers/neighbours with a 3 mile radius !! Gonna chat with Dave, and hopefully get the ball rolling Dusty

Bike looks great Dusty and those pipes look very nice indeed I think, and agree with you, that given the challenge of getting the right fit with the look you want, the bike really needs to be with the pipe maker. Dave and Kenny have made loads of pipes for loads of specials and can tweek bits here and there to get clearance from the frame, stand, under the motor etc and will be bespoke to your configuration. looking forward to seeing the final design as you are not far away from the finish line now John

Don't they look good! They seem to fit well too, although still not sure about the ground clearance! Bike does look mint!

Hi John In normal circumstances the bike would go up to Dave and then to Alonze, but London to Scarborough just isn't gonna happen any time soon, maybe even this year with the rate things are going. A bike courier is gonna add Β£300 to the cost which I cant afford, so trial fitting and measurements from Mouse's bikes are my best bet, although still risky. I did think about Rd400 pipes, as I know they will fit but I'm unsure how they would work with the Pv engine - I think Pv exhaust ports may be different dimensions (larger)- something I will discuss with Dave. Once the pipes are sorted it's just wiring in the M unit which will be a challenge as I hate wiring ! Again I was gonna get Dave to do it but will have a go myself I expect. Hi Mouse. Pipes fit well actually. If the bellies were less in diameter they would fit almost perfectly. They sit against the underside of the frame tubes under the engine They do seem very big compared to other pipes. Length would really suit the bike with 6" cans Dusty

Hi Dusty It's Mutts pipes on my leftovers build. It's just the cans are Kenny's When you look at the bike they are actually quite short Steve

Post by dusty350 on Feb 4, 2021 15:22:36 GMT 1
Cheers for the pic Steve. There was always gonna be a compromise regards the pipes. I think stingers would look great, but create other issues. They would be stupidly loud in use, and the bike has been built to be roadworthy and legal, even if I never ride it myself. I've Googled hundreds of images of this type of bike, and nearly all the road based bikes have cans, for obvious reasons. I've had a good chat with Dave today who gave me a few options, but I've now ordered some Ypvs pipes in stainless with 6" cans. The link pipe between the last cone and the can will be a bit shorter than standard, and on the limit for the design needs of the pipes. The rear brackets will be welded on by my welder mate once I offer the pipes up. Its a bit of a gamble I know, but it shouldn't be a million miles out (hopefully). Couple of weeks to get them done so we will soon see !!

Did a small but essential job today. The kickstart lever would have hit the rear brake lever when starting the bike, so I needed to reduce the length of the pedal part. It's a nylon material which made life really easy. I measured the depth of the threaded hole, as I didn't want to reduce it to a point I broke through into the threaded hole; 20210213_141110 by dusty miller, on Flickr The neatest way to reduce the length was on the lathe. To begin with, both the left and right pedals were the same length, but a few minutes on the lathe reduced it down; 20210213_145035 by dusty miller, on Flickr Now it's fitted back on, I have enough clearance for the kickstart. May have to reduce the length on the gearchange side now, just to even them up a bit, although I wont reduce the length as much on that side; 20210213_145142 by dusty miller, on Flickr Dusty

Nice solution Dusty and yet so obviously simple I the exact same issue on a set of Tarozzi rear sets on a Triumph which resulted in the brake lever actually breaking. I wont indulge in the attempts I had to resolve it but it was nowhere near as tidy or as simple as this one. Top job John

Cheers guys Yep, a simple job for the lathe. Before it would have been vice/hacksaw/file and hope you could achieve a neat finish . There is something "therapeutic" about using the lathe - well, for me, as a lathe newbie anyway ! Gotta do the same to the ali pedals on the 400 too. I need another project bike now so I can make all the spacers from scratch Dusty

Dusty, I have a set of YPVS TSA's sat in storage if you want to offer them up to the build as well. Got several sets of standard pipes but think you've crossed that bridge.
Let me know..

Hi Al Thanks for the kind offer mate. I've ordered some stainless pipes off Mutts now, which will be ready soon hopefully, but thanks anyway. Mouse also offered to remove them from his 31k hybrid for me to try, but I think the trial fit of his Dent pipes have proved the Pv pipes should fit ok (fingers and toes crossed !!) Thanks again Dusty

Pipes arrived today 20210311_171551 by dusty miller, on Flickr They look lovely. The end pipe from the last cone is 80mm long rather than 100mm standard length, in an attempt to keep the pipes as short looking as possible. I also like the end can design, with the rolled tail pipe; 20210311_171612 by dusty miller, on Flickr Next job is to get them to fit !! Dusty

Started to fit the pipes today, starting with the left side as that would be the difficult one due to side stand mount and chain run. These are designed to fit straight onto a Pv, so although my engine is Pv, the frame is Ac 250d, with a modded stand and mount, so this was always going to be a bit of a gamble. I loosley fitted the exhaust flange and pushed the downpipe in to see where the pipe would sit; 20210312_095802 by dusty miller, on Flickr Pretty good straight off The pipe needed to move outwards a bit though to clear the chain, and I found it was up against the side stand bracket - actually the small, angled gusset that had been welded on the back for support. The bolts had thread showing too, plus the nyloc nuts on the back were quite chunky - all adding to the pipe not being able to move out. First thing I tried was reversing the bolts so the narrower bolt heads were exhaust side of the mount; 20210312_102442 by dusty miller, on Flickr And then, with a Dremel, I started to grind a curve into the gusset that would follow the curve of the pipe. Took a few goes before I had removed enough metal; 20210312_124903 by dusty miller, on Flickr I also had to swap one bolt for an even narrower profile button head bolt ! It's tight under there but the pipe now passes by without touching anything. I painted the curved metal support with some black enamel to protect it. I love these pipes as they sit quite close to the bike, and they tuck in under the engine really well; 20210312_100033 by dusty miller, on Flickr I fitted an end can o get an overall idea of length; 20210312_120743 by dusty miller, on Flickr Really pleased with that. I didn't want the pipes going past the back of the wheel - they would look too long, so these look great. I'm really pleased with how well they fit. Next job is to do the same with the right side pipe, then final fix the exhaust flanges, and then I can work out where to mount the brackets too. I can then get the brackets welded up by Glen, and welded to the pipes, then polish them and the end cans and hopefully that's them done Dusty

Lucky boy that they fit lol
I'd have had a sweat on worrying about them fitting π
Hope you are ready for how loud they are, was surprised by mine π
And that was just idling with closed valves
