        Rated 5 out of 5 by from Great product This bore kit came with everything I needed and gives great examples to assemble over all I would highly recommend FORTNINE as my parts supplier.

        Rated 5 out of 5 by from Fits mint! Bought this kit for an 08 grizzly 700, it fit perfectly and was very good quality. Don’t forget to take your locator pins out of your old cylinder and put them in this one. This kit does not include valve seals. I definitely recommend changing them while you have everything apart so order a set when you order the kit. Make sure you stuff everything with rags so you don’t drop your wrist pin clip in your engine. While you’re in there check your timing chain, gear and valve clearance.

        Questions

        I have a 2011 crf250r and thinking of buying the 270cc kit. Would I need to remap my bike?

        Asked by: 5th pinned

        Does this include the front and rear cylinder and piston kits or is the price for each separate.
