today i changed my dyno needles and put in some dyno jets cause thats all i had.. well after finaly gettin it all done and putting in the jets that it told me to it ran like crap.. i then put the largest dyno jets in that i had ... 134f with mixture screw at 2 3/4 turns and 138R with 3 turns went out and it still ran crapy.. i coverd up one of my snorkels coming out of my air box and now it runs great! i still dont kno what to do bout the jets with both snorkels but im goin to wait till i get me some dual duncan fat boy 4s on it till i jet it for the dual snorkel... i think im goin to keep my dyno jet needle in and get some larger kehin jets for it cause i herd this is good combo but if anyone has any suggestions then help me out..

If your needles have grooves, move the e-clip on each needle down (toward the tapered end) one groove and try again. This will raise the needle in the needle jet and allow more gas to pass through.

Sounds like you're still lean. If covering up one snorkel makes the bike run good and you're using the biggest jets DynoJet supplied, you might try raising the needles like I described. If they don't have grooves, you can buy small washers at the hardware store and use those.

Hope this helps.

i could try this.. but its all ready on the 5 position towards the tapered end.. theres only 6 positions i also go to spaces on top that but i dont kno what that does haha.. but thanks i might go try that

 

scrap the dyno jets and get Kawie jets............people with prairies have committed suicide tryin to get the 650's to run with dynos.

 

Yea, sounds like your needles are about as rich as you can go. DynoJet must not have anticipated owners opening up their air box as much as we do.

I have read where some folks have been able to get them tuned in. Too bad those people aren't responding.

Good luck.

best bet get dial a jet kit for it solve your whole problem had one on my grizzly awesome by spring have a set on my vforce i say set cause 2 carbs

 

700kid keep us posted, i really like your snorkel setup with the carbon hood.
was considering doing the same thing to my machine.

 

you should do a search on the jetting with dyno jets , i believe it was alltoys that found that the biggest dyno jet was smaller then the std jets from kawi. he had tried them all, and stand with the kawi jets.

 

yea i have done lots of searchs on here and am getting lots of help.. im going to order me some kehin jets but im going to keep my dyno jet needles in and see what i can get out of that..
