| Big trouble with 97 Suzuki 250RMX Need help with soo many issues here... It may sound like I'm running in circles with my description of the problems
Since I bought my 1997 Suzuki 250 RMX it has always run a little rough. The previous owner hadn't change the gas in two years and the float was sticking, etc... until I flushed everything a few times. But... It still runs rough and is prone to crap out, when taking off down the road. Like it's loading up and hesitating. It also has (from time to time) made a knocking noise. Actually... the engine just always sounds loose. Hard to explain.
So, I decided to put a new piston and rings in as I don't think the previous owner before ever did. Thinking it would make a difference in performance and take care of the knock. Well... the knock seems to have gone but.. it's still running poorly. Even more so.
Soo, I took the carb apart and cleaned it... cleaned the plug (which was black) and took out the Reed valve to inspect and clean it... though it looked fine. I also flushed out the old gas from the tank (about 3 months old) and added fresh gas, again. I also called a few shops to ask about the air screw setting which I was told... Is 1 turn out.
Anyway... It still runs like crap... I messed with the air screw but turning it, FIRST 1-1/2 turns out... Seemed to run only a little better. Then I adjusted the air screw to 1-3/4 then 2 turns out and it seemed to run a little better but it still hesitates at lower r's. When it gets up to higher r's it starts to open up, but... Now I hear a weird noise, almost like the Reed Valve if flapping or possibly an exhaust leak. Which I never heard that before.
Pleeeease. Someone help me. I would love to talk to someone... feel free to PM me, I will check this forum frequently.
Thanks for any help I can get.
