Hi eddavnct:

I'm weighing in on this because I have strong opinions on it. Not the flywheel, just modifications in general.

Unless there is a known defect in the design that you can fairly easily improve on - leave it stock.

So, if you're racing or saving the planet with emissions mods, do your best. If you just want a good reliable ride - leave it be.

My 2$ worth.

This is on an Oilhead - right? That bike doesn't have enough flywheel to worry about lightening it. That was a performance mod done to the /5 and /6 bikes which had a solid, heavy iron flywheel. I haven't really tried to keep up with all mods that might be made to Oilheads, but I've never even heard of anybody lightening the flywheel on one of them. Maybe on a full bore race bike .... but the clutch basket is aluminum I think (I can't remember for sure even though I did a clutch job last month), and the pressure plate and clutch cover are about the minimum needed to do the job.

As for the benefits - assuming you had a /5 or /6 or other bike with a heavy flywheel - lightening the flywheel makes the bike more responsive to throttle control because the decreased flywheel weight causes the engine to spin up and spin down quicker, lacking the extra inertia of the heavier flywheel.

fill out your profile so we know what kinda bike you want to do this to!


an oilhead flywheel weighs not much more than a frisbee from what i remember.

I got a 2003 BMW R1150RS in 2005. :thumb I have been riding for over 40 years, and am trained mechanic. My first ride impression with my beemer was that it had very little flywheel effect. That is, it revved quickly and decellerated just as quickly. This is OK when racing, but makes it difficult to maintain a steady speed on the road. I am of the opinion that this is part of the surging effect, that is common on the oilhead bikes. I don't want to argue this OPINION, just my observation. :hug

Not a Chopper type eh? I have hot rodded almost every Beemer I have had and wouldn't have it any other way. The C and CL has a slower reving engine and RT or GS flywheel improves the revs.:dance

Yes, you have me pretty much pegged. If you like beer and women we can still have a beer!
