It might look shite, it might handle shite, it might not go very well, but a 4 cylinder 2 stroke is the most wonderful sound ever. Sometimes I fire mine up just to listen to them :-) oh I don't disagree with the sound track, just wonderful, its like a 2 into 1 exhaust on a 2 stroke (something else I am working on), not necessarily practical, but the sound is something else and on a triple its just ace !

yes, that is mild and will be fine, sure I responded to your PM about it, or was it an email, or text, anyway, yes that is fine for a starter map

having worked on both bikes many times, in allsorts of states of tune and condition, personally if I had to choose one it woukd be the RG over the RD, but purely because it is easier (in general) to maintain IMHO, but if I was going to spend £15k or my hard earned, I'd have one of my hybrids any day over either bike, my current new build (if I ever get time to get back to it), will by twice the bike, handle better, have more horses, look better and far more unique, but then, that's what i prefer - each to their own I do know of a few owners who have said the same ....... it was the 2 most happy days they had, the day they bought the 500 and the day they sold it ! - having worked on so many, and seen first hand the pain they can inflict on your wallet, I fully understand !

And if your studs are buggered I'm sure mutts just got a set sorted for a mate And I'm talking totally shagged Steve Steve, you are right, his where more than a tad knackered, done a few for people on here now, but your mates where the worst to date as I think 3 out of the 4 needed doing

Right so I take it I need to find Tec on the piston then go back 1.8mm then get the timing mark on the stator to line up with the flywheel mark Steve correct, TDC, turn flywheel clockwise for 1.8mm to 2.00mm, then align the mark on the flywheel to the stator by moving the stator plate to align, lock the 3 bolts up, turn engine over 360 degrees, check marks still align, job done

before squeezing larger carbs onto stock rubbers, measure the inside lip of the rubbers, the part that the carb spigot bumps up against, that will tell you how big a carb you can fit, anything bigger will be a waste of time as it will effectively be restricting the flow and cause turbulence
As Jessy says, you can buy the larger rubbers, not cheap if memory serves me right though

that is a good job, its very tricky doing that repair, not to be taken on lightly, need the right bit of kit to machine that properly

what size is the rear as I had one, was too big for the KR1, but 3 stud fitting and no offest (flat disc), think it was either 230mm or 240mm diameter

They make billet cases for the banshees up to 4 cylinders. Displacements well over a liter. As everything is either bespoke, billet and/or involves a great deal of labor those motors can get very expensive. And then you will need a frame that can handle and use that power. At some point it is really no longer an RZ or LC in anything but design. I love them, but they'll cost as much or more than a modern bike that would likely leave them on a track, get better mileage and be nearly maintenance free. but nowhere near as much fun !

yes, the Tourmax discs are good, I had aset for the KR1S here, juast sewnt them back today as they don't fit the KR1 - despite beinfg assured they would, needless to say I've had a hell of a job finding the correct discs to fit a KR1 - interestingly, they cost a sh*t load more than the KR1S discs !

I want a set of Dave's for the 400, but he would need the bike. So it looks like a set of Allspeeds for me, but not chromed - that's too spendy for 'speeds. Probably buy the bare metal and get Jamie to Cerakote them in silky black. Dusty I have access to a 400 if need be, the snag will be the reaset fitting I suspect, f that's different we have no way of knowing where to put the hanger or if the exhaust routing needs to be changed to avoid the rearsets etc

we now do S/S mid range pipes for the LC, they are £640 - I'll be taking some photo's of them soon, made a set for a certain customer (they are on here) and since then we've made another 4 sets, one set is going to Bahrain of all places !

I know, I am thinking of taking my set of clocks off my 421LC and putting some electronic ones on that I do, then selling the LC clocks as I'll break even give or take !

I had the blue C1 of that model, loved it, as you say, drop that front sprocket 1 tooth and have fun ! - I just build big 2 stroke engines now for the same daft grin factor !

Never thought I'd be Jealous of a 700 miles trip Still stuck with 5 mile radius up here 🤣 Plenty to get going with there Steve um, hasn't stopped a couple of your fellow country men bringing their bikes to me last week for fettling...... maybe they drove under the cover of darkness !! - both from Glasgow no less as well ! Nice haul BTW - would go nicely in my new garage I am having built next week !

Did you find what's wrong with the existing carbs, Dave? nope, but they are buggered for sure, fitted my speare set and the bike runs spot on

the choke slide has the cut outs to allow the air circuit for the choke to work, if you look at the choke carb body you will also see a corresponding hole in the casting which lines up with the cut outs when the slide is fully closed, this allows the extra air required for the choke to work through. if you look at the RHS carb body you will see the casting mark for the hole, but its not been machined
HTH

TBH I'd be happy to lose 20bbhp at the top and have 20bhp more at 4k. That much power increase will make it un-rideable without some sort of electronic intervention. It will either be smacking you in the face and making you shut off or trying to highside you as it spins up and dumps you off in a heap. Make a good drag engine or speed record thing. Like you say, lots of work needed LOL - Phil I was going to bring it to Blyton and get you to rag it around to see how you get on with it !!! - would be interesting on a small circuit

Steve, the mid range pipe works equally as well on the 250's, gives around a 25% uplift in power in mid range, similar curve as you'd expect as well, I'll have to post some charts up, not given much thought until you mentioned it really, might even revisit the pipe and design one specifically for the 250 to see if I can lift it a bit more.....

Then start doing them for 385 ypvs heads 😁 Steve I am nearly there, just need a few more heads so I can do an exchange basis, got one here ready to go if your stuck, bloody things are expensive to buy at the moment, so waiting for prices to drop a bit !

no such thing as stupid question in my book, just one of an enquiring mind
Don't rate Sebring ones TBH, higgs are pretty good, but I don't like the look of them TBH, lots of options out there, comes down to budget, what look you want, any performance characteristics you especially want etc.
There are a few good threads on heer that have discussed exhaust options to death, I am sure somebody will post up a few links etc for you in due course, or try the search function on the forum as that should help you as well

Thanks guys, I won't go into too much detail as its upto the customer to decide if they want the details divulging (they are on here) The engine is a NON PV engine, 73mm bore cylinders, 10mm stroke (as per Phil mentioned, but is a very different engine to Johnny's), the engine has cost a fortune as everything is not only brand new, but a lot is billet, the crank will rev to 12k if required, the crank bearings have been massively uprated to allow for this The LC frame has been braced, as has the owner !! - his intial response on his first test ride was "It goes well, fooking dangerous TBH !! " - he hasn't let it rip yet as it needs bedding in and we want some steady miles on it while we check everything is working as planned. At the moment its running 35mm carbs, we plan on trying some 38mm's and also the new ignition system which has a flywheel that only weighs 300grams, current flywheel is 650grams (Yamaha one is 1560grams), its running an 8 plate clutch with light springs (more on that another day as I may start making these to sell) We have another 5 sets of exhausts to try on it, each having a different characteristic, the aim is to have 2 specs, one for big power, target is 120+bhp the other is to have huge mid range (think we might have hit that one already, but time will tell !) The intial tests are promising, engine temps are staying very low (54 to 60 deg) and I have a new head design in the pipe line, which should reduce temps by 6 to 8 degs all being well, but again, its time and money, none of this development is cheap and I only have so much time and money to throw at these new parts etc Its also running on oil pump !! Watch this space for more updates, or check out the "Malton Dyno Club" FB page which is where I publish all of the developments and tests etc

Been mad busy for last 8+ weeks, but inbetween all of the madness I had a chance the other week to test out one of the new engines that I've been building for a customer, I would have posted up the initial results sooner, but stupid photof**ket shagged it all up, so now using imgur Anyway, initial results look promising, hit 100bhp bit sooner than I expected (8150rpm), not complaining though ! And the 100bhp at 9000rpm has been knocked out of the park....... There is still lots to test and develop, but we are going to get some miles on the LC first (yes its in an LC ), then we will run with bigger carbs and a new ignition system I've been working on, then we have 5 other pipe designs to test and then I might think about doing abit of port work ...... Watch this space........
