discharge Posted December 18, 2004 Report Share Posted December 18, 2004 alright, just got my 916s on, finally got it fired up today and it doesn't idle well at all...ugh....it doesn't have much pick up either in the low range.... thing is, i installed the biggers jets and im running 280s...but noone around had the pilots which DMC recommended...they said use 30s but i couldn't get any at the time....would this be the reason why its running crappy? sounds like an idiot question and im fairly sure this is problem but im not sure... thanks Quote Link to comment Share on other sites More sharing options...
stclark816 Posted December 19, 2004 Report Share Posted December 19, 2004 Sounds like to me you need to go up on the pilots. Try you some 30's. Quote Link to comment Share on other sites More sharing options...
sredish Posted December 19, 2004 Report Share Posted December 19, 2004 what size pilots do you have and how many kicks does it take it to cold start? Chances are, DMC and stclark are correct (even tho he's from MO) and you may just need to find the 30s and put them in. Starting and idling issues often are due to the pilot jet and if it's lean it might not want to idle or start well. Quote Link to comment Share on other sites More sharing options...
discharge Posted December 19, 2004 Author Report Share Posted December 19, 2004 yeah, im running the stock 25's in it now and its running like crap....so the 30s should fix it?...if so i guess im gonna have to order them.... thanks for the help guys Quote Link to comment Share on other sites More sharing options...
Wallynut Posted December 19, 2004 Report Share Posted December 19, 2004 Yea, ya gotta order them unless your in an area that the dealer deals alot with banshee's. None of the yamaha dealers around here had any, had to order. Lucky for me, the main distribution for the midwest is right near here, two days to get them.

Ducman Posted December 20, 2004 Report Share Posted December 20, 2004 You probably need the #30 pilots to run as good as possible, but a lot of people run FMF fatties on #25 pilots so I would think you should be able to get it to run decent on them. Have you tried turning your air screws all the way in and backing them out 1/2 turns. Also if you richen the needle 1 or 2 positions (1 or 2 clip positions from the blunt end, middle clip is stock) it will help compensate in the 1/4 throttle range for a leaner pilot. The needle will probably help with the "pick up" and get it on the pipe quicker. Quote Link to comment Share on other sites More sharing options...
discharge Posted December 20, 2004 Author Report Share Posted December 20, 2004 yeah the changes that DMC recommended were 280 mains....30 pilots...3rd clip on the needle...and 1 1/2 turns on the carbs...im gonna pull them off again once i get the new pilots...i'll try it out with changing the needle like you said Ducman and see if it makes any sort of difference...

PUSH THE THROTTLE Posted December 21, 2004 Report Share Posted December 21, 2004 I'm pretty fat on my pilots for my 916's but I run the Trinity 35mm so I can't tell you what size you need. I'd go up and adjust the air screws for the best throttle response and see what changes when you ride it. Post how you like them when you get it dialed in.

discharge Posted December 21, 2004 Author Report Share Posted December 21, 2004 alright ran it again today, same problem, it really lags in the powerband....when i sit there revving it, it sounds like it should...it just won't idle and doesn't seem like its making the power that it should be?...i don't know...i fooled around with the airscrews and that didn't seem to help much, i backed them all the way in and then did the half turns but that didn't seem to help much.... so then when im riding, no more then 10 minutes it starts pissing out coolant from the overflow hoses in front...which i'm pretty sure was a bad thing, so i killed it and loaded it back up... its a real pain in the balls to start it when its cold to, i mean granted, it was no more then 25-30 degrees out when we were riding it but still.... thanks again for all the help...im not all that great with diagnosing the way it should be jetted....

Banchetta Posted December 21, 2004 Report Share Posted December 21, 2004 Try this for a start: 300 mains, needle 4th clip from the blunt end, 30 pilots, make sure you clean the carbs out w/ compressed air....your carbs might be plugged up...let me know how that works...also make sure you have the choke tube in place between the carbs (1/4"x2" long), then make sure the carb slides aren't in backwards (cutaway should face the air box) if they are wrong, then you have the wrong slide in the wrong carb, just change them over...

dmcman2003 Posted December 23, 2004 Report Share Posted December 23, 2004 discharge,im no pro but i could not get my 9/16's to pull the fatter pilots(27.5.30} it had the problems your decribing,but with the fatter pilots,it just would not pull off of idle worth a shit,put the stock pilots back in and and it cleaned up alot i run 290's,k&n,no lid,2 1/2 out on air screws raised needle clip up one pos.runs great,but i dont think these pipes will ever come off idle as well as toomey,fmf's that i have had in the past/them sonbithes do cool though!!!good LUCK.
