hey everyone, my ds spits back through the carb when you touch the throttle lightly. it has done it since new. its about a year old. you sit idling and push the throttle a little bit and hold it and it will spit back .sometimes it will kill the motor when you start to take off. any help appreciated

 

Have you tried adjusting the pilot fuel screw under the carb?

 

Mine does that when its warm. My pilot screw is at 2 and a half turns. Which way would you suggest going with it?

 

ive turned the screw in and out at different adjustments and it doesnt help the spitting. i have a dynojet needle and jet in it but i dont think it would make any difference

 

I just went thru that issue with mine. I even took mine to an authorized dealer who jetted the bike and adjusted the carb but did not fix the problem.

The problem is a loose wire on the ignition coil.

The ignition coil is mounted uder the tank and the wire can been seen from the left side slightly above the rev limiter. It is a black wire and the bike will start once off but tends to act up when lightly pressing the throttle.

I discovered this while installing an RPM gauge on the bike. The coils needs to be tapped in on the installation at which time I discovered the loose wire.

If you cant find the wire contact RON WOODS and ask them to fax you a copy of the installation sheet for the RPM Gauge and you will find it.

Good Luck,

Joseph Oceguera

Excelent info Joseph, this is the kind of feed-back that makes this forum so good.

DSBOMB; If that doesn't fix it though, check the valve clearence if you havn't already done so.

 

THANKS FOR THE INFO GUYS, I'LL TRY THAT COIL WIRE WHEN I GET A CHANCE. THEN MAYBE THE CLEARANCE. I'LL LET YOU KNOW WHATS UP
