Well, I did the $.22 mod yesterday, only it didn't cost me a cent! Already had some washers from doing the same thing to my XS650.
WOW!, what a difference! Turned pilot screw out 2 turns, but didn't drill the slide and don't feel it necessary. Really woke this bike up, and seems smoother and really revs out with an urgency it didn't have before.
Well worth the 1/2 hour spent to do it.
I hadn't planned on raising the gearing, but now I think I'll give it a shot. Couple questions, though. For those of you that have done the sprocket swap, How much did it lower your RPM's on the highway? I'd like to be turning about 300 rpm less at 60 or so. If you made the change, did you like it?
I figure if I know I'm going to be doing some more serious off-roading, I'd just put the 15 back on. For most of my normal riding, I think the 16 will be the way to go. Oh, and what size is the C/S nut?
I already have 36mm and 32 mm sockets from previous gearing changes on other bikes. Hard to tell looking through the sprocket cover what it might be.
One more thing. Where are you guys getting your 16T's from? Is there certain brand/part# I could order from the dealer or out of Dennis Kirk or something?
