thanks

only input i have is for you to sell me your 'sport engine, exhaust and anything else you wont need after the swap.

 

get a laser lever to make sure ever thing is staight and and extra set of hands, there should be plenty of room to put that engine in, good luck

 

well, this project is comin along nice. i got the front and rear mounts all made tonight, and its tracking pretty good. so i got the top and bottom mounts to go, dont really need em but gunna do em anyways. the only thing thats gunna be a b***** on this thing is finding a place to mount the radiator kuz the pipe gets in the way...

and if you want the motor and everything else, the crank is seized....

 

Hate to rain on your parade, but that dirtbike motor is not counterbalanced and will vibrate the fillings out of your teeth in a quad frame. These types of swaps are known for snapping motor mounts. Making rubber mounts will help. Tryin to keep the front end of that Sport on the ground is gonna be another problem.

 

Stretch that swingarm about 4 inches. That should keep the front end planted. I had a cr250r motor in an 87 trx one time. At high RPM's every thing gets blurrrrrrry.

 

nah i rode it about 10 feet the other day to see how everything was.... it dont ratlle like you guys are saying... i had it running for the like 10 minutes.... dont rattle any more than the 230 motor did....

 

and i dont think the mounts are going to break kuz i thought of that alread yand i maqde the front mounts 1/4 inch thick... they definatley aint snapping

 

Bubba199 may be on to something here. The 230 engine is not a smooth running engine either. I have to put locktite on a few screws that hold the plastic on to keep from loseing them.

 

You'll need a little better ride than 10'

Take it out and ride it hard for a day, and see what you think then.
