Yep, I would recommend 11:1 over 10.25 though. I made that mistake.

Bro, look out in Amazon for the PISTON(Wiseco 11:1)
I grab mine for 115$ with rings and gasket :tup:

If you going to change piston to bump compression, grab the 11:1.

With a stock cam you MAY have detonation. A bit more duration, and later intake valve closing, will help to bleed off some dynamic compression, which will make it more pump gas friendly. BUT, it may very well work fine. Just be sure to have the carb tuned perfect. That is a big factor in how an engine will both perform, and if it can suffer from detonation when running high compression. Also, I have used the 11:1 (with a damn big cam) and it is a nice piston.

I was planning on getting a stage 1 cam. Any recommendations?

Yeah, don't waste your money on a Hotcam. Best to pony up for a HD valve spring kit (like from Kibblewhite) and either a cam from Webcams or Megacycle. Personally, I like the Megacycle grinds. There are only two, but, they work fantastically. The 252x2 would suit your needs well.
