But if it won't start, how can you set the idle?if the idle is set too low it won't start!
I didn't mean it that way. I was speaking theoretically. Kind of like the "If a tree falls in the forrest" thing. Maybe I'm just not getting it, but having the CDI know what your idle is set at before the bike is even running is kind of like running into the forrest to see if the tree did make a sound, thus unqualifying the original question.Originally posted by Truespode
The statement that it won't start is pretty inflamatory as it is describing an absolute
To my knowlede, the wires running to the carb are for the throttle position sensor. I'm straining hard here, but I believe the gray wire deals with the ignition timing (relative to the piston's position in the cylinder) I will research this more to see if I can find out exactly what it does. I thought that the gray wire kept the ignition timeing somewhat retarded even at high rpms.I thought that was a WR-only issue, also? I think the accelerator pump is mechanical. I'll have to verify.Isn't that why there are wires running to the carb? To operate the accel pump and communicate with the bikes ignition system? Remember the grey wire and how it effects the ignition of the bike?
Actually..I might have a project for us, I have been trying to nag my brother into helping me perform the "BK" mod. It is a carb mod from Brian Kinney, Tim Ferry's mechanic. You have to drill and tap a tab on the carb, put an adjustment screw in and change the timing/duration of the spray from the accelerator pump. I have all of the documentation and pictures, everyone that has done is amazed at the power difference and ease of starting. Brian told me the bikes pump is way too rich from the factory and that is what caused my cold fouls this winter. Anyway, with your attention to detail and surgeon like nerves, we should be able to do it. A sixteen year old did it to his and 2 of his friends bikes...so I would hope we could do it. Once things get a little better for me, I can load her and do it in the surgical lab(your clean garage). Let me know what you think, if you need any specifics, do a search for BK carb mod on Thumpertalk under the YZ forum. It is interesting stuff. J
That was one of the things mentioned to help in starting the baby thumpers. Increases initial rotating speed via shorter lever arm(kickstarter), if I am visualizing this correctly.Originally posted by Okiewan:
Oh and by the way, the BBR kickstarter turns it over faster than stock

Whatever the benefits are they can't be more RPMs from the same effort
