I am trying to jet my 1991 RM 250. I have just finished restoring it. Here is the problem. When I start the bike I can start it cold with no choke. When it first starts it revs moderately high, but then will settle down. It doesn't really want to idle stable until I turn the airscrew counterclockwise like 3 turns out. I am wanting to put one smaller pilot jet in. I am currently jetted by the FMF specs. I realize these are not set in stone. The bikes runs really hard mid and top end. The plug is perfect on WOT plug chop. The bike is really boggy on the low end. Do I need a smaller pilot jet or do I need to raise the clip one notch. I have a FMF fatty pipe, flywheel weight, a new top end that's barely broke in. There is one other thing I have noticed lately. I thought I had the float height set correctly after I rebuilt the Carb, but when I went riding the other day I saw gas had leaked onto the bed of my truck. The float height could be too high. I'm kind of stumped. What do you all think? It smokes at idle pretty bad. I just replaced the wet side (clutch) crank seal and still does it.
