Rich Mixture Vs. Voiding Warranty?
05/31/11 at 16:05:16

As many of you know, these bikes are way too lean, and I'm worried that it may harm my engine. It comes from the factory this way and if problem should occur, would they consider it a factory defect? My guess is probably not. So, I would really like to hear others who have worried about this as an issue. I'm kinda hell bent on making an adjustment, since the plug is whitish, but also wondering if i should wait it out another nine months?

It's under warranty, ride it ! If its not running good, its a warranty issue, let the shop deal w/ it. When its outta warranty, start hackin,.....if thats what make you feel good.

It runs good until I push the rpms a bit, then it takes a little time for the gas to catch up( I guess). I've had other single block bikes; that loved being pushed; that was in the early 80's.

That begs a question. What is a typical number for rear wheel horsepower for a late model, stock, S40?

Does a stock LS650 have any more or less horsepower than a stock S40?

And, to stay within the thread, how much HP gain can we expect from richening the mixture to something more stoichiometrically correct? Can we achieve 14.7 to 1 (the elusive lambda ratio),.. or am I dreaming? White plugs indicate something more like 18 or 20 to 1, eh? No wonder richer jets are discussed a lot here!

Just wondering,...

Yep, they ran richer back then, but all engines run leaner now, not just these bikes.
Funny thing is, while running leaner, all engines now last longer than ever before. And many put out more hp too.

yeah, but I've noticed you have the spacer mod.

Only because it "needed it".
I had a perfect idle, (brass plug never removed) it run perfect from 60 on up, (145 main jet) but had an irratic surging motion in the low to midrange. One click on the choke would smooth it right out. The spacer mod couldn't have fixed it better.

My advice has always been, fix what needs fixin, not just because you read or heard it somewhere. I do know of 3 bikes (friends) that run fine as stockers. Mine is the only one out of the 3 that had a ragged midrange.
And if it "needs fixin" while under warranty, I personally would make the shop do it. They may be forced to keep it feds legal, but they are also forced to make it run good.

Reply #12 - 06/01/11 at 07:16:09 Oh, On the other side,....I'm an old guy, not often heavy into the throttle much, never climb 8 mile 6% grades on a 100 degree day anymore, but if you do, stepping up on the main jet mite be a good idea !

I bought the bike in Feb. and I babied the hell out of it in this breaking in period. now I'm riding in 100 degree weather and it isn't thrilled with me getting heavy on the throttle.
