Can someone give me the pros and cons of a stock stroke and higher compression piston compared to using a +2mm stroke and either a stock compression or slightly higher piston. Did some talking with Hot Rod and thinking about their new stroker setup.

I like the way my stock bore motor runs. I know these is more power there but i don't need it for the type of racing i am doing i need it to last a 2 hour race. I would call like rage,dasa,racers edge az they are all good shops and will get you the power you are wanting.

if u raise the comp above 13:1 from what ive heard ur playing with fire unless u change the crank every couple rides . then the race cranks only last about 10hrs . hope this helps u .

I have way more than 10 hours on my machine and my friends bikes with the same pistons both of them have over 100 hours with no problems,

i caint belive ur friends have over 100hrs on a high comp pistion yall are very lucky . check the thread on blown motor . thats what happened n his case . ive talked with one of kawis team mechanics and he said they had to tear them down after every race and they were useing the aftermarket cranks he said the stock ones were lucky to make it through a race .

Well believe it. Me and another friend both have cp 13.5:1 one's and he says he has 125 hours on his and my other friend has a dasa 14.5:1 with 50 hrs and they are still running strong.

Stock cranks. The one bike was bought from lonestar it was in ATV sport last year and has a complete dasa top end and it is still running great with a good ammount of hours on it.
