Im in the proccess of ordering some new crankcase bolts. my question is on the parts diagram they show 2 different bolts. I cant remeber how many of each one I need their is the 50mm and 55mm

Believe there are only 2 of the longer bolts. If I remember right they were at #6 and #3 below (but I have slept since I did the last one).
But I have been told the 55mm bolts are _ONLY_ to be used when you have a stock muffler and it has the new braces that go down to the crancase cover.........If you remove the stock muffler/lower brace you MUST either get a shorter bolt or put a couple washers in its place because it will actually punch a hole thru the block into the crankcase when it bottoms out, and eventually leak oil thru the threads of the bolt.

Hey Thanks I ended up oredering all shorth ones since I have the Croosover Muffler with the new Braces. Thanks again probally goin to order the cam also since I already have the motor apart

If you had problems with leaks I would just order studs they are Lil costly but worth the $
