hey guys ive been fooling around with the idea for a while .... but i finally got it just about done. i used the fmf gold fatty and made my own extension from the head since it come out crooked like a dirtbike exhaust. plus the carb is straight so i had to fabricate a new intake from the seat to carb out of 2 in pipe.
I had to cut the swing arm wider for the engine about 1in.i also run a 40mm kehein PWK .
i call it my Ubermonster lol.
what kind of modded blaster you guys got ? i get pics of mine soon.

Full throttle for 30 mim and its hot ,only looses some power,. But ride mid yhrottle n it stays cool w plenty power ... Built not bought it pattened. Lol nah but thats my shop ,B-n-B,kustoms
 
Looks good! I love the look of the air cold motor in the blaster frame, it looks to be at home!
it feels it too. only bad i ran into is if you Fat Kid" kick it it kicks back ,so u better be committed when starting.. this engine is up for sale for bout 500 n i got a 79 yz250 bottom end no head or jug for 200.also have a kdx 200 watercooled 93 complete engine only no stator for 400.plus shippin on all engines

Pretty good job!! Funny, some pics it looks bigger than 250 (wink). Pipe is a little rough looking but as long as it works. That old thing have points or cdi?
 
yea the pipe was realbad then i fabbed this one . i wasent going for looks but didnt want sh*t on my engine lol . that was a hell of a snake to weld up . i own a welder ,never said im a welder.lmfao but its watertight thats all that matters to me really. i fill w water to check it . i got a 81 vintage cast aluminum CDI 5 wire. plus i got the swingrm streched 6.45in,and banshee axle,weight center ratio vs power is right ,it has great traction it will climb any hill i choose if i stay on it allthe way.
