i got a sweetheart of a deal on an 02 for like 500 bucks, the previous owner was a "do it yerselfer" and drained th oil and coolant for his 500k service, problem is he forgot to add coolant, long story short i bought the bike and had the motor rebuilt, allong with many new parts as it had been sitting for a while, ie, intake manifold, bearing, boots ect,
the bike ran fine for about 2 months then i took it out the other day and it seemed to not be the powerhouse it used to be, and at about 3/4 throttle it sputters and there is no throttle responce, it almost actl like it is choking,
the guys riding behind me said they some some black smoke, when i run it in my garage im getting some black sut on the floor,
it runs great at low RPM then when yo push it, it starts acting up

im at a loss, it ran fine then abng runs not so fine..............

any ideas ????
thanks
Pete

 

02 700's were know for bad coil packs. Could just be a dirty carb or bad filter too.

 

thats a great place to start, i figured it was allong those lines,
thanks!!!

 

welcome,make sure you have at least 1/8" play in the thumb throttle.might be trying to turn the spark off.... adjust on cable up cable from throttle...

 

ill give that a try and let you know

thanks guys!!!!

 

gave that a look over last night,
throttle cable had a little play in it, so its ok,
thanks anyway

 

i figured it out,
the bike was let sit in the rain for so long, the needle , or choke jet, whatever its called, was stuck part way open in the carb, a little wd40 and i was back in business, damn thing never ran so good.
thank for the help!!!!!!
