Frequently Asked Questions

Short answer: Yes

I suggest ARP Headstuds for anything but stock compression, you can torque our ARP Headstuds at up to 45 ft lbs of torque, taking the headache out of blown headgaskets. 

Yes, the 108mm cylinder has a larger sleeve than the stock cases accept. 

Absolutely! I suggest a fuel programmer even on stock Raptor 700's as they come lean from the factory. If you add any kind of engine mods to your motor, you will need a programmer.

Every bike is different, and must be dyno tuned to run properly. You can use a big 3 map when installing a programmer, exhaust and intake. After that, you should get it dyno'ed or you will be possibly running lean and damage your Raptor.

Yes, most of the Web cams require clearancing, especially the most popular web 290 cam. Do not run with out clearancing or will damage your motor. 

Hotcams stage 1,2, and 3 can be run with no modifications to the head. The Hotcam Stage 3 is the most aggressive of the 3 and makes the most power. 

12.5:1 or greater. You can run the 12.5:1 compression with Fresh 92 or better octane, but over 12.5:1 compression Race Fuel is recommended.  

75-80 HP Max. I would only suggest using the OEM Crankshaft as a core, and add a high quality Carrillo or Crankworks rod. We do not suggest HotRods crankshafts, they are prone to failure.
