Jetting KFX-700 HMF duals
I put my duals on last week; went riding this weekend..142F/145R mains, and my quad seemed to sputter at full throttle. Almost like a rev limiter, I am at sea level, no airbox mods, and after riding yesterday pulled both plugs and they were slightly tan/black. this thing seems like it will really scream once I get my jetting squared away, I ordered dial-a-jets lastnight when I got home just out of frustration. today i put 140F/142R jets in and it sounded better(less sputter @ WFO) I don't know if I should run it this way in fear of a top end meltdown???? Any Thoughts. Help me help the V.[img]i/expressions/face-icon-small-confused.gif[/img]

to finish your question about performance, the duals made a noticeable difference from bottom to about 7/8 throttle, I read up on jetting Keihin carbs tonight and it sounds like I need to fatten up my main jets...quick response and great sound I might try 145/148:152/155 I'll keep you posted.

You need more fuel .... and AIR. I have 142/145 jets , plus the dial a jets on max ..... and it took
two holes in the air lid to ballance it. (used the sliding gate type from the dial a jet people ). It runs
purrrrrrrrrrrrfect. No hesitations, no coughing, no spitting, just smooth power all the way.
It does make huge difference in power ..... you are going to like it.
Tell me about your experence with the Elkas ???????
