Thanks for the response! what about installation and tuning? difficult?

The installs the same as doing a top end and the tuning is not that difficult just like tuning for a b pipe the just follow they're jetting recommendations

does it require me to send in my sleeve to be ported? or is everything done at home
have not done much engine work other than my ada racing head

How much is there top end kit? They make great big motors but why not send in your cylinder to Jetmaniac and Blue for one of their kits. The 781 is scary in a lightweight hull for a beginner. I am not sure on the pricing difference but would bet you can get a better deal and one stop shopping at JM/Blue. The 781 I believe they prefer to send in your motor and bore out the cases a bit but I believe the 735-760 top ends you can order just the cylinder to install on your cases. Then follow the tuning etc. I have had one of their motors and will buy again when I get a chance for a motor of that size. My buddy has one in his SuperFreak that is carbon fiber and has scared me for years

It's $500. I currently have a b pipe and Ada with 35 domes on 701. I got another itch for more power haha. I only saw exscreams version of top end kit. Haven't looked around much. What would you recommend? Also come September I'm most likely going to upgrade to an AM hull

I would look into the jetmaniac top end kits. I think they are similarly prices for a bored out cylinder and ported how you want. If mild or wild porting

I recommend the 781 but depends on budget because I think they only sell that motor complete.

Go to jetmaniac master parts list on Google. It will send you to his forum page. His motor and top end kits are all on their with pricing. They can make your motor up to an 828cc with a stroker crank I believe.

I wouldn't waste the coin on small bore motors unless it was for racing and had to stay at a specific size motor
