I have the V Force 2's and they have great power but...
I have now broken one and my buddy has broken 2 of them right where they bend.
After being as absolutly far away from camp as posible when they broke, I am now willing to give up some power for reliablity, what wont break but still makes for good power?
aplication= the motor is about as built as you would go with a 350cc dune port t5's Dyna ign., .040 shaved head
Motor had only 20gl of fuel run thru it since the rebuild and shoving a piece of carbon fiber thru my cranckcase is not my idea of cool.
At least the local Honda shop stocked replacements at $70 a side
yea they stock repacements so I would say they must break fairly often to be stocking a whole bunch of $70 Yamahaha parts at a Honda store
fyi: symptom = cold exaust one side, lack of power
the dead hole , cyl will pick up every so often while riding it to
where the truck will come get it.
