when did you pull it off the bike or how did you ride it before you pulled it off?

I barely ride the 250R but I have been riding it alot recently. And I have never jetted the bike yet. I have had this Dyno Jet kit for a long time. After riding it more frequently the bike does not run really well from 1-6ishk rpm. Then it comes alive. I need to install this kit ASAP. After do some reading I suspect the bike needs to be richend up a little down low. She may be lean, with the Area-P and snorkel removed. I may just try the washer trick. Or just use the needles from the dyno jet kit.

You have the Stage 2 2193 kit? Put the needles with the clip in slot #3, 2 washers and a clip on top of those (see attachment). Adjust the idle mixture screws (remove the caps to get to the screws) 2 1/2-3 turns out and I bet your problem is solved!

As kkim stated, we need a picture of the ceramic insulator, viewed from the end of the plug.

if you put a full exhaust on do you have to re-jett it? if you want your bike to run good i mean and not break down... i just installed a fulkl system but have no clue about jetting it or anything... can i just take it to a shop or something and theyll do it or do i need a kit n easy enough to do myself?

This is a pretty good link that gives an idea how to read plugs. Lots of Pics of Plugs (http://www.dansmc.com/Spark_Plugs/Spark_Plugs_catalog.html)

Yes you need to re-jet. Read the Sticky DIY threads in the Tech Talk area.

how's the bike running since installing the pipe? are you sputtering/stuttering/missing etc along the powerband anywhere? more often than not, exhaust makers will suggest rejetting somewhere in the installation instructions. there are some threads on the forum that details both jet kits and mixture needle shims. check it out and see if these options are in your 'wrenching range'. CAN you do it yourself? if not, i'd pay for a shop to do it. let us know what you're gonna do k?

I think im gonna try and just install these needles first and see what I get with that. I have the DynoJet stage 2 kit 2193.001
So g21-30 you recomend putting the clip on slot #3?

kkim

If that's where the instructions recommend, I would start there.

Just seeing if any one has tried just using the aftermarket needles with no jet changes. And what results they got, before I do it. I was thinking maybe trying to duplicate the affect of "raising the needles" w/ washers, but using aftermarket needles w/ there different tapper. I will let you guys know what happens.

Yes and since the kit includes 2 extra circlips, I put one on top of the two washers. When I tried to install the needles with just the washers, one washer fell off. Of course, I could have used vaseline/grease, etc. I just figured the extra circlip would fix it for good. :D
