Matt90GT said:your idle problem is more than likely due to a plugged pilot jet. still be sure to inspect the needle/seat and float height.
mike-evans said:I removed the card, and carb bowl and re-adjusted the floats. I tilted the carb slightly, and adjusted the tab on the floats until the floats were parallel with the bowl mating surface, which gave me about 5.6mm, i could see the needle valve just seating in its position, so floats must now be in correct position? Re-fitted it all, and no fuel leaking. Stil a pig to start, think it might be down to my/wrong technique, as i got a spark and got fuel (wet plug), topend has approx 6 hours on it, noticed 1 of the reeds was slightly lifted on one edge, i turned the reeds over, and are now flat, not sure if you can do that though? Jetting is standard to the manual, so rich from factory, so might drop pilot down 1......
I am not sure of a compression, as I havnt put a gauge on there yet, but to kick it over, there is ALOT.....which makes me think it could be my technique? "whenfoxforks-ruled" yes the tang is resting on the plunger ontop of the needle valve without compressing it. I know that the needle valve is there to close off fuel flow in relation to the floats, but what is the plunger ontop of the needle valve for?laramik said:I'm feeling you on the pig to start thing too. What's your compression when cold? I just got this bike and someone had just put in a new piston but skipped out on spending the extra 13 bucks for a gasket set and figured rtv silicone woulkd work just as well. Lemmie tell you, it didn't. So after cleaning all of it out of my cylinder head and original gasket I noticed that there was some serious gapping between the top of the cylinder and the head like someone must have used a screwdriver to seperate them. The new gasket on mine is not really filling that gap so filled it just on the outer lip with high taemp caulk but that only is over about 1cm of the actual outer surface. Its holds compression once ran for a minute at like 95 but once cold its at like 65. I basically got this thing for free because I got it along with a 97cr125r for 450. The cr needs a piston which is on order but after that I shouldn't have a problem dumping for at least a grand, but if I'm just on a losing battle with this thing ill just sell it for parts or to someone local for 200 bucks and use that towards a little 4 stroker for the kids.
