Sandking Posted June 6, 2015 Report Posted June 6, 2015 Message camatv hes the guru on the pv set up. If it has trinity domes your going to have to get new ones. Quote
bansheelapointe Posted June 6, 2015 Author Report Posted June 6, 2015 really why what wrong with trinity domes Quote
bansheelapointe Posted June 6, 2015 Author Report Posted June 6, 2015 how do you message people Quote
bansheelapointe Posted June 6, 2015 Author Report Posted June 6, 2015 not sure if there trinity domes but they seem to be working just fine jettting is real close i think maybe the main is too big, just looking for comparisions Quote
hercalmighty Posted June 6, 2015 Report Posted June 6, 2015 There seems to be a few people who have trinity domes where the squish band gets tighter as it comes to the middle of the dome. The squish band should get looser as it gets to the middle Quote
bansheelapointe Posted June 6, 2015 Author Report Posted June 6, 2015 well it runs real good now but what are the symtoms and im still looking for this camatv guy to chime in with some jetting info Quote

Coupelx Posted June 7, 2015 Report Posted June 7, 2015 although the trinity domes are a known issue. theres so few 421 cheetahs out there i have no idea if they had the same issue. hell they may have used an off the shelf cub dome on them. Remember that the powervalves have an effect on tuning. the best thing i ever did was drill out a set of jets to .125 to put in the powervalves. lets them react faster. Quote
sleeper06 Posted June 9, 2015 Report Posted June 9, 2015 Might wanna contact lms1977 on the site or one of the coal hill guys they love those powervalve motors over there might have some insight for us . I always jet every motor the same , get it close , chop it, adjust from there I always do main first then needle but others do it in reverse Quote
lms1977 Posted June 9, 2015 Report Posted June 9, 2015 my banshee stuff is long gone as far as the motor is concerned. but your jetting seems fairly close, make small steps see what it feels like and check your plugs. 1 Quote
