Has any used the polini 177 kit which uses the 60mm Stroke Crankshaft ? Or the pinasco 177 kit what uses the 60mm Stroke Crankshaft? I'm going to do a full rebuild on my px125 and I have not seen any one use the 190cc kits.. Just want to know if they are worth doing.
Thanks

apriliars250, Why did you choose those kits?
What are you looking for, performance wise?
If the LML is still fitted with it's standard crank and bearings, I would change them, before doing any tuning ,as the are known to be suspect!.See here 👇.

they sell them two kits made for a 60mm Stroke. Performance wise I want it faster but I want to keep the original style carb. Because I premix my other road bikes and the auto lube is nice to have. I know I could fit a px200 engine but I just want to use the engine I have. Just thinking of them two kits because they are the alloy cylinders and more cc is generally better apriliars250, Why did you choose those kits? What are you looking for, performance wise?

Yeah the lml is all standard still. The plan is to do a full rebuild any way.. The parts are so cheap for these scooters.My crankshaft for my two stroke motorcycle was £600. So this I going to be a nice and quick project.

I hate to do it, but I agree with Mij. What are you looking for? For it to be a bit faster. It's never going to be motorcyle speed but with the kits with 60mm Stroke it would be 187cc. So in general more cc is better. I still want to keep the original style carb for the auto lube.. It's not my every day vehicle.. I'm going to be doing a full engine rebuild so Im want to do everything at once.

I will be porting the cases. And there is not really a budget it costs what it costs. Its not my commuter bike. I suppose you could class it as street racer. I don't mind rebuilding a engine every year either.

Cost what it costs, OK, IMHO ; Sell the Lml engine, it's a limiting factor, Pinasco rotary 200 cases, MALOSSI MHR 210 kit for 57mm crank(more timing options when fitting a 60mm crank, Quality clutch, 30mm carb or bigger, 60mm crank, variable ignition, BGM gears and primary drive, hand built exhaust to your engine tune (try PM tuning?) 30+ to high 40's bhp 😉 Or you could build an engine around this👇 www.vespa-lambretta-teile.com/Malossi-Rennzylinder-Kit-MHR-PX-200-wassergekuehlt-worbspeed-mit-Kopf-und-KolbenA clutch like this example, but depending on your gearing 👇 www.sip-scootershop.com/en/products/clutch+sip+cosa+2+ultrastr_93413000The above is off the top off my head at the moment, probably more to follow, just giving you some homework 😉. Apologies ðŸ˜ðŸ˜š, A lot of the above is b*ll*cks ,as I forgot you want to keep the auto lube carb which is a (very) limiting factor . ðŸ˜ðŸ˜³ðŸ˜³ðŸ˜³ Mij.

I will have to look in to them. The parmakit looks good. I have never been that keen on single piston rig pistons for road use

This kit too 👇
LML's need the carb lifted by 10 mm ,I believe .
Just found this, read his description for info 👇
Happy hunting, have to go and check on my mate who lives alone and has very bad health, been checking on him most nights for weeks, have to take him tomorrow afternoon for a heart scan . And help him fix his wambretta 😉 at some point in next couple of weeks, if he's up to it ! Usually back home 11pm/ ish, will check forum then.

I can fully recommend the BGM177 kit on LML cases. No need to port the cases as the ports are large enough, you actually take out the cylinder base ports slightly. There is loads of scope with 57 or 60mm cranks, altering piston skirts. The Germans easily getting 25hp+. Check out GSF thread about it. I still run autolube without issue on mine.

apriliars, maybe to narrow it down a bit,you can tell us the cylinder kit/s you like or we can suggest to you, cylinder kits and the reasons for our suggestions,once you think you see one you want, we can go to crank suggestions, then carb, then gearbox, ignition, then exhaust suggestions, if you wish?
That may help and narrow things down for you.

The main question is has any one used a 60mm Stroke. If I was going to choose a 177 kit it would be BGM.. polini or malossi.. The kits I said in my first post are designed for a 60mm Stroke. I will be doing a full rebuild and upgrading all other parts apriliars, maybe to narrow it down a bit,you can tell us the cylinder kit/s you like or we can suggest to you, cylinder kits and the reasons for our suggestions,once you think you see one you want, we can go to crank suggestions, then carb, then gearbox, ignition, then exhaust suggestions, if you wish?

I still want to keep the auto lube I was looking at the BGM kit. Because I'm doing a full rebuild I was thinking of using a 60mm Stroke Crankshaft. But can't find alot about anyone using the 60mm Stroke I can fully recommend the BGM177 kit on LML cases.

You don't necessarily need to buy a kit designed for a 60mm crank, if you do, it can cut down the tuning options you have, as the kit will be designed for top end or grunt or maybe half way between those and to alter that you'd have to possibly top or tail the barrel( remove material). IF however, you buy a kit for a 57mm crank and fit a 60 mm crank, you can more easily tune the barrel to your liking, by adding gaskets or spacers to the top or bottom of the cylinder or both till you find the state of tune you like or wish to try, these can be changed at any time, as they are not permanent.
I agree with mista freak moped, that the alloy Polini barrel he looked at, is not worth the money, heard some of the BGM kits are unreliable, but maybe worth checking out the latest batch? With the alloy Malossi kit just out, unless you wish to take the risk of being an early adopter, I would wait a few months to see how reliable they are, also have no idea what the port timings of this kit would be but this is the kit I'm most excited about, of the ones you mentioned.

I'd suggest having a read of the BGM spec sheet if you haven't already. It lists set ups for both cranks.
There were some reported issues on the early kits if piston issues but they appear to have resolved this now.
