I’ve also thought about this subject before. There are two schools of thought in doing this. Would you go for a faithful reproduction, or perhaps an improvement?
I believe Vespa had their T5 cylinders manufactured by the Gilardoni foundry in Italy? Terry Shepard (a well known two stroke tuner) design what was to be known as a TS1 kit (in the scooter scene) to fit a lambretta. It had an almost YPVS reed valve (same size but fractionally shorter as opposed to the original piston ported inlet, but more importantly was aluminium and nikasil lined as opposed to cast iron. Much better cooling allowing for extra porting.
Now these were made in batches at the Gilardoni factory. Quite a few had to be made at once, so someone had to stump up big.
I think I’d prefer an LC cylinder in aluminium and nikasil lined with an intake to take YPVS reeds and better porting. Possibly 375cc to start with. Externally it could look almost identical.

From memory I’ve not seen a PV headlight fairing on an LC. It looks really good. Did you have the decals custom made?
p.s. I find your avatar quite ironic.

It’s funny isn’t it? We are all different. I really like the F/N 2 indicators. The small ones just look like cheap nasty generic items.
I have to agree with OEM units though as my preference. Hell I’m even going to use an uncut stem on my latest hybrid. Trying to keep as many things OEM to offset the other modifications.

Money no object I’d go the other way regarding drying time of cleaning solution. I used some fast dry panel wipe (for degreasing in between layers of paint) to clean my wiring loom connectors. I thought at the time I might use it to clean the components on my next engine rebuild. These days I expect it’s not to more expensive than petrol? Jon So Trichloroethylene is a no no? Best degreaser that we used to have before we knew what the consequences were PPE is you friend. Would you drive without a seat belt? Jon

I put 7k on my LC hybrids The more I think about it maybe your right. I had a better idea on the F2 as it’s all but standard apart from paint, microns and triumph calipers. A hybrid is a bit more of a difficult thing to price. I was thinking maybe it would sell at around £6k max, as very rarely people like a hybrid 100% and want to change it. However the insurance value should be the replacement value to me. In which case your probably nearer? Jon

Wednesday night is beans on toast night in our house: Heinz chilli beans, toastie loaf, a couple of rashers of crispy bacon, grated cheese on top, melted under the grill. Live like kings in our house…. On the rare occasion the FPO switches it to Tuesday it screws me up and I cant get up for work on Friday as my body thinks its Saturday… +1 (almost). I use almost the same ingredients. First I very lightly grill one side of the bread. Turn it over and slice mature cheddar on it and then melt under the grill. A few good glugs of Worcester sauce after the cheese has melted. Move the shelf down and bacon that been cooking below up. I like the bacon medallions with no fat at all (sorry got to do my bit somewhere. Beans heating the microwave (sorry). Tescos are good. Then onto the plate, cheese on toast first, then beans, then bacon. Garnish with a few splashes of Jack Daniels BBQ sauce. Jon

Hi all,
I’m in a bit of a dilemma. My insurance is due Friday and the 2 RD’s are currently agreed value of £5k for my LC/TZR hybrid, and £5.5 for my Kenny Roberts F2.
Trouble is I think they’ve gone up in value since last year, and want to give a new price on renewal.
I can take photos and fill out their for to email them, but I’m undecided on value.
I valued them realistically (I think) last year. Both are not 100% but close. Do you think RD’s have gone up by about 10% from last year, or more?
I’m gonna take photos for the insurance tomorrow. Perhaps if I post them on here, a few can comment on value?
It’s even more relevant as I’m thinking of selling the Kenny F2 this year.
Jon

17again I’ve made them in the past. rdlccrazy.proboards.com/post/297729Probably still got a couple, if you want me to check? Otherwise I can make you one. They are stainless 13mm AF with an M8 thread, so plenty strong enough. Jon

Dusty mate, your work is always flawless, but could I suggest you try using white spirit instead of petrol for cleaning parts? It works just as well, it's much safer, and has a lot less noxious odour. I always add just a tad of oil to it, to prevent any rusting when it dries off. Only downside would be it might not dry off quite as quick as petrol. Both around the same price these days too. Money no object I’d go the other way regarding drying time of cleaning solution. I used some fast dry panel wipe (for degreasing in between layers of paint) to clean my wiring loom connectors. I thought at the time I might use it to clean the components on my next engine rebuild.

Yamaha fzr's ran fuel pumps to feed the carbs Don't imagine they draw that much power The pattern ones on ebay say 60L per hour so unless you can go through a tank of fuel in 20 mins should be fine Steve Steve, I don’t think it’s a case of the flow has to match the fuel consumption. I think it has to be way higher to give some sort of pressure to the carb. 60L per hour is 1L per minute which is higher than the target of 1 pint, or 568ml that we used to use. Jon

I used to run a 34mm Amal carb and fuel pump on my highly tuned Vespa. The banjo on the carb had two spigots. One. For in, and one for a loop if it overpressured. We used to aim for at least a pint a minute on a tuned scooter without pump. I know it would never use anywhere near that amount but needed some pressure. Jon you might well understand my problems if you've had a vespa! My bike is a lambretta gp with a 32k motor in it ,space is a premium! So il need to run a pump,was your pump a vacuum or 12v? The new casa 265 motors run a mikuni vacuum pump but il need more flow than the type they use It was an Amal pump running off a vacuum spigot on the reed block. Looked like this: www.saving-old-seagulls.co.uk/phpbb3/viewtopic.php?t=5153Jon

Isn’t it funny how Yamaha seemingly couldn’t decide on a design and went forwards and backwards over time?
The LC has a circlip, then it seems the 31k had a screw in cap, the the N/F2 and R a circlip again, then the TZR a screw in cap.

Some LCs as well now, including my bike. Classic insurance as well, crazy. There were some youngsters starting to drive classic cars because of cheap insurance, but i think they were going to close the loop hole. As said before, insurance companies need proof of the bike being road worthy.Best to MOT it or they won’t pay. Give them a call. I did with mine and was told no MOT no insurance. Which insurance company are you with? Peter James say it’s fine. Jon

RD250/400 engine and the rest...dunno lol. Appears to have no spark plugs for some reason. Alex I can see spark plug caps so assume they are on spark plugs? I trying to decide if I can see wires? They could easily be lost from view in that photo. Jon

Did you drill the brass air corrector ball out, clean the ‘jet’ then replace, after vapour blasting? If not they could very well be blocked. I assume also the needle jet (atomiser) was removed for both processes?

2R8 (or 2R9) carbs were ‘supposed’ to a good upgrade for a YPVS ‘back in the day’ as they were true 28mm instead of 28mm to 26mm.
Even got a set myself for that reason. In reality, there is no real world difference to note.
I imagine not the end of the world to jet though? As mentioned its the choke that might be the deciding factor.

I can’t remember whether it was the NK adapters and these calipers, but I’m sure someone said they had to fettle them a bit around the fork mounts?
If so better trial fit before anodizing etc.

I don’t get the list of supposedly new genuine parts that have been catalogued. There not in new condition after they’ve been painted, like the wheels and heads.
I also don’t believe the list 100%. For instance the list states a new crank was used, part number 2R9-11400-00 (second page, penultimate entry). However the description says: ”the crankshaft was re-built and balanced using new bearings, con-rods, crank pins, big end bearings, thrust washers, all four main bearings, centre labyrinth and outer oil seals.”

Have you considered keeping the YPVS cylinders and doing a 385?
Banshee and YPVS crank is the same 29L-11400-30.
