Hey 300E owners -
Many of you know I have a '99 300E. For two years I've been messing with the thing. The recent bout of throttle sticking (solved BTW) had me riding my '99 XR280 all the time. This really opened my eyes as to hpw fast I could ride by being smooth and keeping my entry speed up.
Now that the 300 is up and going again, with the most recent changes to it I find its power delivery to be too sudden and the reason why I can'r ride whoops on it. I geared it 13/52, down from 14/52. Makes 3rd more usable but accentuates the abrupt power delivery. Also ground the slide to a #7 and re-jetted to a 42 pilot/175 main (actually 45/180 for the cool weather now). The bike as an FMF M-20 (no stock pipe) and the TCII siliencer/SA. I do have the stock silencer in the garage. I run 93 octane Shell unleaded and 48:1 Yamalube 2R BTW, no race gas.
This past weekend I not only had it jetted too lean but also knocked the pipe seal loose at the engine. Totally unridable! Jetting richer and fixing the pipe seal helped a bunch, but the XR is still way easier to go fast and smooth on in the Piney Woods of LA.
Questions - What else can I do to make the thing run as though is has a steady throttle opening, instead of revving all the time? Mess with the power valve? If so, what changes would you make to it? Also, what about going back to the stock silencer?
A 13/50 might be a good idea, or maybe a 14/53? Just to take the edge off a little this way? The 14/52 just needed too much slipping in the tighter stuff.
Any other tricks I missed? Thanks guys!!!
