Well , like the title say's , I didn't really do a build thread on this one , but more or less just wanted to show the final part of the build.
I bought the last 18' I could find out here in the NW about 5 months or so ago. I bought it a lot earlier than I was expecting to , so it sat a while. But anyways , the past two weeks I spent the time to tear her down to the bare frame , and use assembly grease or loctite on every nut and bolt on it.
List of parts , and / work I had done.
Milled head from 0.065" to 0.045".
New PWK 38 with JD jetting kit
New Boyesen Rad valve
New Scalvini pipe
New Husky edition FMF powercore 2.1
Modified airbox
Carbon Pro Skid plate
Carbon Pro Clutch protector
Carbon Pro Gas tank protector
Acerbis X-grip frame guard's.
Side note : I didn't build my 125 , as I had another guy do it ( Thanks Joel ! ) And I could not believe the lack of grease ( especially in the rear end! ). Enough grease to put on the end of a Q-tip was what I found in the rear linkage. The steering stem wasn't bad , but the grease they use is like thin Vaseline. Another picture attached here is the horrendous piece of shit stock reed cage. Along with what the Rad valve looks like compared to it.
I knew 90% of the thing's I was going to run into , in this build. I was expecting it. And now that I have fixed everything ( except suspension , which goes to FC in a couple weeks ) this should be a pretty badass bike. It will be a perfect match for my 125. And after 35 years of racing and riding , this is the first time I have ever had a matching pair of bikes! I can't freakin' wait !

Good god! Why not put them in a race!!??
The Shop
That's one nice ride
I found that the throttle pull on these bikes are extremely heavy compared to the four strokes. If you’ve find the same thing, go for domino throttle setup. Probably the best mod I’ve done to mine.
Enjoy riding ?
I would be curious as to what jetting you end up with. I have the same bike, almost the same type mods. (PC, Vforce being the difference). Even have a STIC to shove in the carb once I get the jetting down.
Keep us updated, please!
Pit Row
It's kind of a milestone for me honestly. I started racing in 1982 and I have never had a matching set of bikes ( big one , little one ) so literally 37 years of this sport , i finally have a pair of bikes. I have a great feeling about this year and the level of the fun factor should be off the hook. Going to try and get my helmet cam dialed in here in the next few weeks as well , and plan on getting some full moto video's of some of the races I'll be doing.
Initial start up / warm up the bike seemed lean on the bottom with the 42PJ. So I swapped it out to a 45PJ and it seemed quite a bit better , but maybe a tad rich. Going to put the 42PJ back in and play with the air screw a bit more. The top end with the 172MJ / blue needle in 3rd clip seems to be jetted correctly......But even with the mods I did , it seems to lack over rev. It definitely pulls harder then the stock set up basically every where , but just a lack of over rev on the top.
Next time I take it out , I'll play around with the 42PJ and air screw a bit more. I also need to play around with the power valve a bit , as I'm running the stock spring and stock setting it came with from the factory. Depending on how / where I set that , it may slightly change the way I want it jetted as well.
Was a tough practice day. 90 degree's , track was bombed out pretty bad by about 11am , and being sick for 2 weeks with a sinus infection really zapped some of my energy and strength. I will know a lot more after my next ride. I may just try and pull the STIC metering block from the PWK 36 and put it in my PWK 38 on the 250 to test it. I'm not sure if it'll fit? If it does , it may be worth the test.
Post a reply to: Not really a build thread , but finished my 18' TC 250 today.
