XR650L jetting

11 posts in this topic

I have a dyno-jet stage 1 jet kit and I drilled the slide holes to 5/32". Instead of shimming the needle can I just move it to the fourth position down? Isn't this the same thing as adding a shim?

Check my sig. The fourth position will be a little leaner, I think you'll be happier in the middle postion or third one down.

Keihin jets and the stock needle shimmed work better than the dyno-jet kit.

The DJ kit is better than stock, but this way is better than the DJ kit.

I've run both ways.

Did you put the stock jet back in the carb or did you buy and install a keihn 165 jet. Does it make a big enough difference to buy and install the keihn stuff or is it a not that noticable improvment and where did you find a washer that was snug around the needle, radio shack didn't have any.

I used the Dynojet 165 that came with the kit. From what I have read the Kehin 158 is about the same as the Dynojet 165. There is some inconsistancies between manufacturers I suppose. XR_Dave is right though, I have read many reivews on the subject and just modifying the stock is the way to go but since you already have the Dynojet kit, I thought you might want to know which works best. I wouldn't use the 165 unless you do have an aftermarket pipe though. The stock will be too rich with the 165. :thumbsup:

Hey uw, how do you like your "Q". I'd like to "quiet" my L down a bit(pro-circuit t-4).Is the power significantly more than stock ? :thumbsup:

I have the old 98db version of the Q and like it ok. It definately chokes it a bit witht the "quiet" insert in the end but without it it's as loud as the power core 4. I would like to try the new 96db version but the cost doesn't outweigh the sound right now. That being sade it is quiet enough not to anoy folks around me. I wish I new what db I really had. Mine is due for a repack though. Power increase over stock was better off idle response and more top end. But it was a bit louder too.

Hey UW, this is the Rock Island connection. I am going to shoot for the re-jet this weekend. What does your schedule look like?
