I have a Artic Cat DVX with a yoshi slip-on and jetted. I am about to put the hot cams (intake and exhaust) in as well as a high comp. piston. No my question is the 13.5 compression too much? and if i do decide to go with the 13.5 do i need to consider a new head pipe. Thanks in advance.

 

you will have to run race gas 110 octane...and the head pipe wouldn't matter..only if you need the best performance you can get

 

I planned on running 111 Octane.

 

i would get the head pipe too the stock one starts to drop off at 7000 rpm get the head pipe....

 

Do you guys think I need to change the rod with the new piston?
