I pulled the head today to put some helicoils in the valve cover screws. Its been leaking oil out the top cause all the screw holes are stripped out.

sweet, what swingarm is on that thing? ive read a 350x will fit with a few mods and is over an inch longer
 
I just have that one vid I posted already of my brother warming it up and then the valve breaking.

The exhaust header looks custom. Its step welded up every 6-8 inches or so going up in diameter. Whoever did it did an awesome welding job. The muffler looks like a slip on maybe DG?

The swingarm is custom as well its been cut and stretched.

The quad was full on custom set up for mx with a blown engine when i got it for 600 dollars.

I had a kid in the neighborhood ride it today before i pulled the head and he has a 400ex and when he came back he was like dood are you shure thats a 250? haha


I think my carrier bearing has taken a sh*t because you push it and the quad barely rolls.
 
wonder what other quads that bike ran agenst? 200-400 4stroke? 200-300 2stroke? i dont think id wanna take it to a track agenst 450's
 
hmm... interesting... i might wanna duplicate that header for mine.. muffler sounds fine.. but i not sure if my header is stock or not and i think a lil bigger startin on the side of the motor back to the muffler might help breath more power
 
Yeah that was the day I was gonna get some video of it spanking my blaster...lol but the valve broke.

Id like to see some pics of stock stuff because I dont see many x's around and I like to know how different mine is from a stocker.
 
yeah its becoming a big thread, i cant wait to pick mine up to see what all is done to it for sure i shoulda taken pics
 
hahaha.. its not that clean.. front plastics are all chounched up, held together with zip ties, held on with zip ties, fit for sh*t,... rear are ok, crack at the back by the grab bar, frame was painted red..... im debaiting on switching the frame to black, with all black plastics and a red seat,.. my swinger i painted black....

exhaust looks wayyy diff but isk if its the stock front pipe or not
