Have a nice week ADV-Riders

I think my bike is smoother with the new aftermarket FMF powerbomb header and powercore4 exhaust and i have fly racing handlebars with moose barkbusters and protaper pillow top grips also. That helps me with the vibration imo. I use to stop after 20 minutes of riding to rub my sore hands then i was fine. I did 15 hard trail miles after the new exhaust was installed and we never stoped. Imo after market exhaust helped my bike run smoother.

edit: I see from the schematics that I'm missing the N1TC collar. That's why it feels sloppy in the carrier. I ordered one from RM today buts it's on backorder until June 4th. Looks like it just stabilizes the upper need within the spring. Is it OK to use the N1TC without it or should I leave the stock needle in until I receive the collar?

Yes I think you should wait on that collar / you know that carbs a real pain in the ass to remove and replace,so you only wanna do it once.

My chain guide block is shot, bent pretty bad and unable to be straightened. Starting to nip the side of my new chain. My Google searches are not pulling up any results for a 2007 KLX250S. Would the block from another model fit... KLX300, others? Any suggestions welcomed, or if someone has a block they're looking to sell PM me. Thank you!

Here's a picture of the one I have. I only use it on long trips (200+ miles). It works great.

Yes, that is one part - I need the whole block though, which adds up to ~$90 for the item. I'm hoping to find something a little more affordable, there's got to be an aftermarket item for another KLX that fits... crossing fingers a KLX300 part will fit...
thanks for looking and sending the link!

Ok, does anyone know if and where I can get another stock starter jet. Yep, drilled mine out to much. The 0.018" bit broke and I couldn't get it out. So I had to drill it out with a bigger bit (0.032" was the smallest I had) and now the choke doesn't work at all.

Fill it with the too big hole with a gasoline resistant epoxy and drill it again?

[apostle2]

Thought about that actually but I'd like to try and find another jet first, if it's available.

Bummer on the broken bit. Yup, someone else over on kawasakiforums did the same thing. Used a larger bit and I believe they were successful with their repair. IIRC, they drilled it out larger, inserted a piece of material (plastic maybe...don't recall), then drilled out that piece to 0.018". You may want to search for that thread over there.

Thanks, I'll give it a read.

Well after reading this I've decided to pull the jet back out, solder it to fill the hole and re-drill it. The jet is easily removed by just pulling it out with a flush-cut set of wire cutters. To re-install it just lightly tap it back in place. It may be a couple of days before I can get to it but I'll post the results when I'm done.

Speaking of jetting, I finished up mine today. Thanks to my wideband O2 sensor, I was able to get my jetting to be almost perfect for this elevation. It's just slightly richer than ideal. I'm at 0.7 to 0.8 lambda (ideal is 0.8 to 0.9). I have a 135 main jet, 37.5 pilot and needle in middle clip. This is on the Bill Blue TM33 (bored to 34mm) pumper carb.

From looking at a jetting calculator page, if it's right, for sea level I will need either a 140 or 142.5 and a 40 pilot. I'm curious as to what I'll need for a 351, since that will hopefully happen in July.

I'm very pleased with the instant throttle response of the new carb. You really can't imagine the difference until you have one. It really is instant compared to the stock CVK.

Hi,
I've got a 2006 klx 250 that has some work done to it from the previous owner... I'm just trying to figure out what the hell he has done to it.

It runs fine, but it still makes me curious.

The bike has a muzzy full system, it's likely been jetted, in fact I'm sure the carb has been out because the throttle return cable has a kink in it, telling me they bent it slightly in the process.

What I am curious about is the AIRBOX.

This airbox has a hole cut into the top of it that is rounded off... and when I pulled the filter, the strange thing is there is a mesh filter there once you remove the entire filter... but the mesh covers only 3/4 of the round cone surface.

What is the scoop with this?
