just wandering if anyone has big bored there predator I am thinking of the 580 kit from superbike shop I am going to do cams and values and springs and shave flywheel it is already apart at the shop so if anybody has ideas of best kit .Please let me know

 

Is Superbike shop still selling these?

 

yes they are called friday

 

SP700Racer has the Superbike shop 580 Pred on NOS

 

w

 

Hot Seat ( hotseatperformance.com ) sells a big bore kit with a custom made replacement cylinder. HPD (HPD-inc.com ) has some great engine performance mods. Rath Racing (Rathracing.com ) is a factory sponsored racer/ R&D consultant for Polaris.

 

Oaktree, The Superbike kit does work great. save your money on the cams, there is not one at
this time that makes any power gains. The stock cams work great, even with mods. Let Gary @ Superbike advise you on what works.

 

sp700- you been to the track on yours yet? 300 sand or 1/8th mile asphault? The farmers around here don't buy them to hot rod them. lol Still trying to find a built one to play with

 

Your right not to many cams out there but web cam has some with .020 more lift and more duration they will also custom grind one if you know what you want also looking to 1mm bigger values every thing helps I just wish more would do better r&d on this motor.

 

Mark, we run alot on the asphault 1/8 mile. I have not run on the dirt yet. we are building a new engine and setting my Pred up for the dirt this winter. I hope to bring it up to your area for your big race. (work permitting). on methenol I ran some mid 7's around 85 to 86 mph. My bike is very light weight, and set up for drag racing. So, far I have switched to the 4-snow tires, rigid suspension, and wheelie bar set up to run the dirt next year.
