Threw some temporary tires on the bike to make it a roller! finally!! I can actually move this thing around now.

installed the petcock last night. but of course, I had no gas in the garage so I couldn't test to see if it leaks yet.

got my Motoholders front fairing stay. hopefully weld up the mounts for that and the rear tail section tomorrow so make them permanent.

fit a 748 rear shock on the KX. milled up some .250" brackets to adapt it. turned out nice. should work better than the original 85 shock. I turned some spacers to fit in between the lower shock brackets so I don't have individual bolts like ya see here. need to order some  longer bolts.





sneak peak of the bodywork on. since, I've had the top fairing fastened to the sub frame. sits farther back now. Looks too far forward in the picture but ya get the jist.



also have the rear set brackets done. they are getting a clear anodize put on them. I'll have rear brakes when I get them back!

thanks Umberto! excited to get it done.

Kawi Green of course!! is there another option?! hahah. it'll have a scheme pretty much like the upper and lower fairing you see in the picture. have to cut up the fairings a little so I'll be putting new paint on them

installed the trail tech gauge last night. Mostly using it for the tach and water temp sensor. maybe i'll add the speedometer sensor down the road. also finally have the rear sets on. next is fabricating the shift linkage...this one is going to be a bit tricky...

Hey guys. Been a while since I've posted but there has been a decent amount of progress on the KX. Spring time gets real busy for me. I have my full time job and wrench on Ducati's as a side gig (this is my fun money, hence the KX LOL).

Just got my rear wheel back from powder coat and put the new tire on. also had them powder coat the chain adjuster blocks, chain alignment pieces and upper motor mounts (a lot more stuff still to be done yet!) put on a superlite sprocket and DID chain. Also have the TOPAR sprocket cover recommended by some of you folks. Took an ohlins steering damper from a GSXR 750 and mounted it to the frame and a ProTek fork mount. should perform very well. have to send the damper out for a rebuild however.

Next is the bodywork!!! wooooo!

Hey guys. Been a while since I've posted. All the mechanical fabrication is complete so it's been mostly a lot of finishing work. Getting pieces powder coated and painted. sanding the tank and tail down tonight to get it ready for primer and hopefully paint this weekend so long as the weather allows. Taking it to mid ohio in 2 weeks so it has to be ready by then! LOL wish me luck!

finally got to ride it down my street for the first time! still trying to get the carb set up just right. I've adjusted the float bowls, needle position, pilot and main jet and it is getting closer. still doesn't have nearly the throttle response I'd like at 1/8th turn to 1/2 but once this bike opens up on the pipe, wow does it move!

I can't see or find what carb your using..
If it's a stock carb I would swap it out for a 38mm Keihin quad vent air striker.
You will gain HP through the entire RPM range and quicker throttle response.
Dyno proven.
If you want a used one, 96-97 KX250, 2000 Cr250.
You will need the throttle and cable from whatever you choose.
Or, you can buy a new one from Sudco for around $200.

Then again, getting your jetting dialed in will have a huge effect on throttle response.

awesome sandblaster! thanks for the heads up. I am heading to mid ohio this weekend with the KX so it won't happen right away but that will certainly be something to upgrade then...
