07 ER motor build

[Jake250ex]

Im tihnking about going with the rossier 14:1 piston and a cam (not sure which one) in my 07 ER. Im worried the starter will barely turn it over. I had that problem with my last quad. And I hate to tear into a prefectly good running new motor but if its worth it I will.

I was thinking hotcam stage 2 or HRC. Definitely has to be a drop in. I want an all around increase not just top end. I want to be able to lug it and get on it and it take off and not bog and then yank my arms off. What do you guys think?

And I imagine Ill need a header to help to. Right now I just have a HMF slip on. I was wondering if a HRC header would fit...?

..with a Rossier complete exhaust and Hot Cam S2 can´t go wrong

I've ridden stg2 hotcam, stg1 hotcam, HRC cam, and the stg1 is where its at for lugging and arm ripping power.... definitely pulls hard down low! I loved it!

I say buy that first, as its cheaper than everything else, and if you're not fully satisfied after that alone, then buy the other stuff to compliment it.;)
