For the GP1200R there are many different variables to deal with and the results will vary. Even though we and other companys offer performance kits for the GPR--- individual setup would be required to properly setup the ski for your individual riding conditions and style.
Weve tailored our performance packages to offer the basics because we feel this will offer the best " all around" performance-- of course, no kit is set in stone and can be setup for the individual's requirements.
Basically we designed our LEVEL 1 kit to be a "pump only" upgrade and should be the course of action you should take to start upgrading your GP1200R
Rideplate
Intake Grate
Impeller
Billet impeller cone
Pump Seal Kit
I havent listed any Name brands because the performance results from different manufactures is tremendous on the GPR platform, and would take hours to go over every posssible combination.
There are also a few "reliability issues" that should be addressed on the GP1200R motors. and this goes for all 66v engines and that is the powervalve issue and the catylitic converter issue. there are aftermarket products available to correct these issues.
Next upgrades would be to the engine--- Carb work should be concidered a MUST when performing ANY motor work to the GPR-- we have seen too many times where people add aftermarket parts to the motor only to go slower or even worse destroy the engine.
Weve designed our LEVEL 2 kit to be engine upgrades to the 1200R
Cylinder Head
Flame arrestors & adaptors
Reed stuffers
CARB REJETTING KIT
Correctly tuned GP1200R with as few mods as I mentioned should easilly be in the 70+ mph range and can be sa high as 74+ mph depending on impeller and options chosen
If anyone has any questions or need recomendations call, email, post and will be glad to help.
