Re: 929cc to a 980cc
Well for you that have seen my prior posts, you know that I've been looking for a little more power. *In those posts, I mentioned shaving the flywheel and litening the crank. *With the input received, I decided it was not what I had been looking for. *
Not being feasable to buy a new bike and wanting to keep up with the power delivery of the new bikes I've decided to bore out the 929 motor to a 980cc (76mm pistons). *And also bump the compression up to 13:1. *According to Dan Kyle, he said it would not be worth it, but I am a person that loves to tinker (although I definately do value his knowledge). *My understanding is that he has only tried bumping compression on a 929, but not tried to bore as well as bump compression. *So the pistons are on order and the case has been sent out. *All in all, around $1000 ($550 JE Pistons, $450 for machining and Nikasil coating, and $50 for a new head gasket and boring of that to a 76mm. *Labor will be free as I am doing this on my own.
I've already port and polished the head w/ a 3 angle valve job and dropped in Erion Racing cams with the Micron Serpent system.
I have no real reason to bring this up, except for sheer excitement. *When I get it all back together, I plan to have it custom mapped, and I will get the dyno results. *Not sure if it will happen before winter as it is starting to get cold up here in Wisconsin. *If anyone is interested I can take pics of the process. *I hope to have it back and together in about two weeks.
