Yesterday, I lost 2 header studs while riding my 800. I thought the stud size was 8mm with 1.00 pitch. It could also be 1.25 pitch. I have bolts of both sizes for now, and I try to start them by hand it it seems to get hung up. It is tight with the header on it still. So I want to make sure on the correct size before I start turning on one of them to get it in. I don't want to be pulling the head to helicoil it.

Thanks

 

In case anyone needs to know this info. It is 8mm and 1.25 pitch...........
