Ayesully810 Posted June 30, 2017 Author Report Posted June 30, 2017 haven't tried different carbs yet, I traded a guy off south texas page a set of stock ported cylinders for a set of stock carbs and pods should be here in the mail soon, ill try those out and see if that makes a difference with a diff set of carbs.

sleeper06 Posted July 4, 2017 Report Posted July 4, 2017 #1 make sure pilot circuits are 100% clear , my jet drill kit came with a really thin needle like tool that fits perfectly in the snout of the carb down the angled hole in front of slide. I've had a few engines do what you describe. They needed bigger pilots with the porting. Don't get hung up on everyone else's pilot sizes keep giving her fuel Quote

A 30 pilot has got it sorted out. Quote
Ayesully810 Posted August 18, 2017 Author Report Posted August 18, 2017 update.. apparently this issue is NOT resolved. This thing will still not start (this is my friends bike) pressure test passed all electrical components in the clear vf2s, 140ish psi ,fmfs ,aggressive trail port, pods - 32.5s still wont start it. If I put a little gas in the spark plug holes it fires right up and idles fine. The air screw is at HALF turn out from seated, any higher than that and I get lean idle hang. I know half turn and 2.5 is the ideal number, carl I know you said don't get hung up on the numbers but my 4 mil 421 with stockers has a 37.5 pilot idk why this aggressive trial port stock stroke would need the same. thoughts? or just keep upping the pilot Quote
Surfrjag Posted August 18, 2017 Report Posted August 18, 2017 Blow air thru the choke circuit for some reason its not working. A good chance its clogged somewhereSent from my SM-G930V using Tapatalk Quote
yamaha04 Posted August 28, 2017 Report Posted August 28, 2017 Tiny jet in the left carb bowl that feeds the choke circuit can get clogged and be very very hard to start. Quote
