The best way to tune that 3V head, is to toss it in the garbage.



Both intake valves open at the same time, and it's a worthless novelty. This head was popular a year ago overseas, until everyone realized it was crap and tossed 'em.

 

ok, but the owner of the bike does not want to spend any more mnoney, and is perfectly happy with it now(when it runs)

i was wondering if that would change any thing, make it run bad, or any ideas.

but yes i do agree that it is a huge gimmik, and it hasnt been the most reliable either. i pulled the topend b/c it wasnt running, that motor is HUGE. not the bore, but the casts they weigh an extra 5 lbs at least, for no reason. the intake ih covered with slag, i dont know if it would run better polished or rough, ive heard both is better. its a pos :lol:
