sounds good to me. iv done a compression test (good results), its getting sprak, rebuilt fuel pump,cleaned carbs. i started it and ran it to day a little and its still acting up at 4000 rpms. and its only got like 25xxx on it. there is no rush on the help, i just am getting frustrated with the way its been acting. i am also sorry if i happen to use "the texting lingo" from time to time.

well first dont run it unless you have the screw in the carb and adjusted like the other carb. the stator is at the end of the plug wires.

maybe it did not run right with the screw, but it sure as hell is not going to run right with out it. Put it in and clean the carbs. then we can be done with that issue.
what are you calling good compression? 95? 145?

by spotless did you clean out all parts of the carb? and you have the plugs out but plugged in to see if there both getting spark? thas is an easy way to see if the stator is fine.

I know it's alot of questions but I'll throw mine out there too lol. How did you check the spark? Spark plug plugged into coil wire laying on top of head? What color was the spark blue or white? My indy400 would start but barely run, ended up being that the cdi box was weak. It didn't really click to me that the spark was white until I had to check the spark on another sled and saw it was blue rather than white, instantly clicked to me what was wrong with my indy400. Changed cdi box and spark was blue, ran like a raped ape.

Sounds like you need a new cdi box.

Nope

You will actually hear difference in opinions when it comes to track tension. I adjust my track so that with the sled off the ground I have 1" slack in center of skid. Others would probably say that mine is too loose so please, don't take my word for it lol.

If it's slipping, it goes CLUNK. The wobbling could be a messed up track, bent driveshaft, all sorts of things.

I set my track tension to the point that it doesn't ratchet - so loose there's 1.5-2" of slack in the middle. I set my XLT to Polaris' specs and roasted a brand new set of hyfax in an 8 hour ride - never again.

Any more than 1" sag and I did have a ratcheting problem.
