zeekdog Posted July 25, 2007 Report Posted July 25, 2007 (edited) e just picked up a 01 for 900 bones. The motor seems to run good in neutral but as soon as you put a load on it she misses like it is starving for fuel or there is an ignition problem. It appears the right side loads up and then fires . Not sure what is wrong. She has toomey T5 exhaust open air box. Not sure on the jetting we are at 5500 feet above sea level. My son picked this up to do some ice & flat track racing. The motor is very hard to sart but can be push started fairly easy. We will be going thru everthing and for the price I do not think we got hurt. Can somebody give us some trouble shooting ideas on what to look for. Edited July 25, 2007 by zeekdog Quote
joneser4u Posted July 25, 2007 Report Posted July 25, 2007 take the carbs down and clean em up real good. Quote
TurboBanshee420 Posted July 25, 2007 Report Posted July 25, 2007 sounds like a real week spark to me. Or even a bad coil maybe. Check the float level obviuosly and make sure it isn't just a fuel problem before you get any further. One thing at a time. You have air... sounds like you got fuel.... so I'm thinking spark. Check your plug gaps... run them @ 24-28 thousands. They may not be gapped at all. That would account for the spark being blown out with any load. How does it run at full throttle under load? might just be as simple as a poor tune. Quote

Once you start to release the clutch and get the rpms up as more load is applied to the engine she develops a miss. It appears she wants to run but the miss is there ll the way thru to WOT. It is also hard starting especially when cold. We are going to start with rebuilding the carbs and see what happens. Any sugestions for jet sizes at 5500 feet. What about pilot jet sizes also?? Quote
