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.

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

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.
