So I have an Lml 150 engine laying around... It's already set up for 8" wheels, so I figured I'd do some performance modding over the summer and put it in my 65 Allstate.
Right now I'm at the planning phase, just trying to figure out everything I need, and how much it's all going to set me back. I'm already expecting to spend a veritable pile of cash, so no surprises there. I have a fairly basic understanding of these engines, and zero experience with performance tuning, so expect some really dumb questions to be littering this post
Feel free to take cheap shots at me or suggest alternatives as you see fit
Before anyone asks, what I'm wanting out of the engine is to be able to hit 65+ mph and get there as quickly as possible. If I could make a lot of noise and look like a complete maniac whilst doing so, that'd be a bonus.
1) Basic stuff
I'll be replacing seals, bearings, and gaskets, obviously. Several years back I took a P200 to the shop to have seals replaced and the owner told me that the reason the seal had failed was that the PO had installed a seal for an Lml engine into the piaggio case. Is there such a thing as an Lml specific seal? I've never heard of that since...
I am also gonna need an engine stand for this project. Saw this one on Scooter Mercato. I like that it doesn't need to be bolted to a work bench. Anyone out there have any experience with it?
I'm planning on going with the Malossi 166. Guy that ran the shop I frequented swore by them, and the folks I hung with at rallies seemed to corroborate his opinion. I'd be breaking out the Dremel and matching the ports on the case to the kit.
Gonna need a more performance oriented crank, so I was looking at this one
Going with a full on expansion chamber. Wondering if ground clearance is going to be an issue with the 8in wheels. Also wondering if mounting the pipe to a '65 frame is going to be problematic. Anyway, these are the two pipes I was looking at.
From what I understand, the stock Lml Reed valve is optimized for fuel economy rather than performance, so that's gonna need to go. Does this seem like an appropriate replacement? Will I have issues getting the cowl over the manifold?
Looking at this one. Seems pretty heavy duty. I'm confused though because it comes in 20, 21, 22, 23, and 24 tooth models. How exactly does one go about determining which is the right one for their build?
The motor currently has stock 10in gearing, so replacing those was in the cards anyhow. I was going to replace them with the gear stack for an 8" Super, back before I wrecked the bike this motor was originally in. For this application, I really have no idea what I should be looking at. Any suggestions would be greatly appreciated.
Well that's all I can think of for now. As you can see, I'm pretty far outta my element here. I'm fully expecting to break some things, blow up some other things, and just generally make myself miserable before I get where I want to be with this. I thought about outsourcing the work, but I'm not going to learn anything that way, and ultimately I'd be less satisfied with the results.
