kylechs04 Posted April 9, 2012 Report Share Posted April 9, 2012 Just had my motor rebuilt recently. Has T5's, bored .20 and had an aggressive dune type port done. Stock carbs (with tors) with 270 mains, needle one down from the top notch, and i believe stock pilots.. I am in Mid michigan about 500 ft above sea level. Was jetted perfect before the rebuild and now.... Starts first or second kick, idles decent, but has a Very LOW rev and backfires and sputters, no power. Compression is good, and no air leaks..... wondering if it would change my jetting that much or maybe a tors or other issue? Quote Link to comment Share on other sites More sharing options...
zach45 Posted April 9, 2012 Report Share Posted April 9, 2012 I would start at 320 and work your way down.. What air filter are you running Quote Link to comment Share on other sites More sharing options...
special06shee Posted April 9, 2012 Report Share Posted April 9, 2012 take that damn "tors" off.. also if you have the factory parking brake set up remove that also!! my tors made my quad act all funky at times!! thats why it went byebye!

bluebanshee98 Posted April 9, 2012 Report Share Posted April 9, 2012 did you have the dune port done before the rebuild? who did the port? i think i can steer you in the right direction if u just got the port job with the rebuild Quote Link to comment Share on other sites More sharing options...
kylechs04 Posted April 9, 2012 Author Report Share Posted April 9, 2012 No i DID NOT have any port work prior to the rebuild.. IRONDOG did the porting im sure not alot of people heard of him. BUT i just put in some 310 mains that i had, and it definitly has the power now. Still dogging on 3/4 to full throttle in 3rd gear on up...

bluebanshee98 Posted April 9, 2012 Report Share Posted April 9, 2012 (edited) when i got my 4 mil and duneport done by hjr i had to change my flywheel/stator pickup gap to .018 and plugs to .022. and with the lid on the air box and 330 mains in stock carbs there was no hesitation or rev limiter type of effect at the top of the powerband at wot. you may have to do the same but i would try jetting first like stated above. you should get an adjustable timing plate and put it at +4 , shift star also if not done already. what kind of air filter are you running? stock air box with lid on or off?
