I have ordered my A-arms and now I want to do some internal work to my engine. I was thinking along the lines of a stage two kit but with 12.5.1 compression piston instead of RWR's piston. What are the pros and cons of new clutch springs. And how much does it usually cost to port the head. Maybe make the intake and exhaust ports bigger like RWR. How much would it cost to port the head and do I have to bring it to a particular place or can my Bomb dealer do this???

 

Do a search on "head" and "port" and you will find a bunch of info. I recently posted some of my findings about head porting and valve size increases.

Bomb dealers are not the ones to do larger valves, leave this to the people experienced in it that have done a number of them.

 

Thanks for the advice.

 

the clutch spring will make sure you don't lose any power though slippage, it was one of the first mods i did and it is cheap and easy. the dealer at the coast told me a trick to change them. tilt the quad on its side about 45degrees and this will make it so you don't have to change the oil, and just clamp off the or tilt the raditor hose up, plus every thing is right there to work on. takes 30 minutes. head porting goes for 150 to 1800.
