[QUOTE="wirefryer#85, post: 1063173, member: 69874"] 3rd time responding, hope it gets through. Since you have decent compression and she seems to be running fat, I'd look at these. She obviously can't breathe as in starved for fuel or can't get it out the back end, it should scream! (no inference intended on your mechanical skills.) Pull the intake boot and check the reeds, if they are even remotely warped , replace them, I recommend Boysen dual stage reeds if you can get them (about 45-50 $ U.S. Is the pipe badly dented, especially right at the head? After 26 years of owners, somebody ran a bunch of convience store 2-stroke oil thru it. Check the pipe for sludge build up. Pull off the silencer and make a couple passes down the block, not at 1 am :ohmy: Pull the fuel line off at the CARB and see if it has good flow. Did you 'cook' the carb or just hose it out with carb cleaner? These Mikuni's are a bit fussy about how clean they are inside. Check the carb floats for saturation AND if they pass, check the float levels. Remove the 14mm nut off the bottom of the float bowl and check for ANY kind of grunge build-up as this is your main jet fuel well. Try these out and maybe she'll run good, the ignitions on the Vin/Evo series RMs usually either work or they don't but don't rule them out either. Good luck!! #85 [/QUOTE]
