The dt200 pump cover etc is the only thing I have seen. ...... My brother rubbersalt and I have been knocking around the idea of making reproduction units w a water cooled topend kit....

A cr125 reed cage will fit if u gently open up the intake ;)

Any knowledge u want to drop on me would be greatly appreciated, im a novice on the r hybrid and what im doing with it. I have a handful of questions that would be more apropriate on my build thread. Saw this blaster motor for sale on ebay, looks very reasonable price wise!

when I ordered my lockup from GPengineering on my 250r build he said that matt shearer and calvin (i assume form cpi) had been working on a custom tuned pipe for a big sabre 250r and then he said McCoy claimed he had a pipe that would put out 10hp more than theirs.....He said it did exactly as...

love my 250r over the 450 all day and night!!!!!!

Gp engineering home of the undercover slingshot lock up clutches!!! He's outta garden city KS

There's an aircooled 200 Yamaha dirtbike that I run into sometimes out trail riding. His jug looks real close to a blaster but I doubt anything will just bolt up other than dt200 but ill bet there's some close ....I thought of Modding an old air cooled 250 r topend to fit ....

Yeah ill hack and fry the swinger for sure,i just havent decided how far to go....im going to get it all tuned and built , then i'll stretch it :) the hard part about using the dt200 waterpump is finding one for sale.....i think the watercooling options would explode for our blasters if a...

If it all measures up good run it! I don't hone jugs unless new rings are used, the pins in the ring groove keeps them in place and they are broke in to the jug.ur compression is an indicator of a worn topend or leak of some kind. Better Yank it and investigate!

yeah we r in the works of getting his jug mated to the blaster bottom, its on the back burner while he goes thru his newly aquired tecate3. main issue w the rotax blaster hybrid will be watercooling and building an intake onto the case inducted jug.....my lil bro gabe aka rubbersalt is...

The guy at GP. Said he was werkn on a slingshot locker for a blaster!!!

I got ahold of GP and bought me a slingshot lock up!!!! $295 + shipping wich wont be much cause they are only a few hours to the west of me!!! The conversation we had included some very kewl info. I was told that Nate Mcoy was the man to talk to on pipes among other things. although my first...

this adapter was used to take up the slack when i put the tm cable on the stock blaster thumb throttle. i took a bolt that would thread into the throttle and chopped the head off , drilled out the center then welded 3 nuts together.I then chopped off the throttle stop on the underside of the...

I have pics of mine and he is right about the sealing. I had to coat it all w copius amounts of hondabond then it passed the leakdown no prob. i have pics of mine on my profile. I dont know if it was the nasty triple port job along w the cr reeds but the build in my sig had the kewlest whiring...

If u look up Nate McCoy on trx250r.net or Google you'll find that he's a reputable extreme performance 2 stroke builder . Now look up some numbers on other 2 stroke engines and look at the typical HP to CC ratios. The yz80 makes more hp than the blaster W half the displacement,lol. Now look @...

This is the best Reed mod on a stock intake. Can be a delicate process and the sealing surface on the sides gets thin.....I shaved my cage a few mm and hogged out the Side walls. A safer and perhaps better method is to welda CR Reed spacer on the intake and build up the sidewall. On the...

Ive been wanting to ride down mulvane in my baja bug and my quad!!! Awesome info bro! I want to check out hutch on the river ? Badlands are overrated imo i went once and wasnt impessed i shoulda spent another 1.5 hours on the road and hit waynoka!

I sniped me 2 sets of vf3's w 2intake boots for $73.45 delivered!!!! thats $36.72 a piece!!!! u cant buy vf3's that cheap for anything!!!! yeah, ive been looking @ some aftermarket heads and i can mill the surface to tighten things up but i wish i had the software for a cnc mill at work or...

If I can machine an intake @ werk to weld on to ur sled jug we r onto something! ..... my rod just showed up in the mail and is ready to be sent off for assembly and balancing!!! any suggestions on who to use ? Im leaning towards crankworks , or hybrid engineering....

I have shaved down the pistons slightly on the exhaust side to advance the timing, saw it on the namura pistons,. I also like to take the hard *90 angle off the crown circumference, gasses hate sharp edges , That's all I got for piston mods .....
