Drz snatchy throttle/ momentary loss of spark?

Recommended Posts

Guys,

I posted this on the intake/ jetting forum about 2 weeks ago and got no replies.

Hopefully someone on here can help me.

I have this intermittent problem with my FCR equipped drz400sm.

When you start from stationary and when you change gears and get back on the gas the throttle get quite snatchy at times, almost like it loses spark for a second and then comes good. Adjusting the fuel screw does bugger all. It may improve for a while but then comes back, regardless of which way you adjust the mixture. I also notice that it is more prone to doing this on cooler or less humid days. Runs better the warmer or more humid it gets.

Stock TT store jetting, 3x3, rs2.

Your help is appreciated

I guess you could discribe it like that.

Yes I have done the I ring mod, even backed it up with a baby zip tie.

It's like the engine coughs and then comes good. Strange it only does it on cool and non humid days.

Thanks for the reply
