I read somewhere that high comp pistons where causing rods to go
its not the HC pistons alone that are doing it, though it does help. Ive known some to have them fail with stock piston and just hot cams, with a pipe and intake. just curious if anyone heres had it happen and with what mods, and at what hours.

This was a great thing for me to read.
I just bought a 08 with high comp piston, cams , and ported head. It only has 10hrs on it, but it sounds like I have alot to look forward to. Oh well enjoy the hp while it lasts.

ya except for with your mods the cranks go at about 10-13 hours so look forward to a ruined case when the rod blows up

Which is why I am gonna call dasa and find out what all they did to the motor. It was Cyle Chislock's bike, and supposedly I was told it only has 10-15 hrs. on it and that it was in and out of the bike because dasa kept changing things in the motor. So hopefull for my sake they put a beefier crank in it.

well I spoke to dasa yesterday and was told that the bike I bought has a 14.5:1 piston and they are changing top ends every 25hrs. The tech I spoke with said they have not had any rod failures, but I am supposed to speak with the owners son who built the motor on the 25 when he gets back in. I found out alot about the bike so though it has not got to me yet (still being shipped). Pm me for details and I can try to help you out.

I highly recomend Falicon Crankshafts. Not sure what they have out for the KFX yet but I have used them many of times and they have unbelivable craftsmanship. We use there cranks and rods and bearing coatings in another form of racing where we rev the engines up to 18,000 rpm and not a sign of fatige from anything. Also no matter what alway get your main and rod bearings coated. This is a new technololgy but is working GREAT!!! Greatly reduces heat and friction....

my 2 cents would be that if they are using the stock crank for all those mods to either send back the motor or get a beefier crank put in it by them...or at least have them warranty it for a while...6 months minimum imo...The falicon crank recommended by slideways is top notch....but it also depends on what type of abuse your going to be putting this motor thru.
