GP1300R OEM head bolts question
I'm doing a conversion, Installed a 1300 OEM top end on my 00 GPR
I thought I could use my 1200 head bolts with a few washers on a 1300 milled head. But the difference is huge, so decided to buy some 1300 head bolts.
Looking at the parts finder and the 1300 head I bought:
I don't think the bolt #9 will fit the holes that are highlighted with a red circle in this picture. Also the required quantities at the parts finder don't match. So there most be a part number missing here? Does anyone know the part number of those four bolts, cause I need to buy a full set.
Or maybe someone could make my life a lot easier and sell me a full set of used ones?
Perhaps trade 1300 bolts for the 1200 bolts that I have?

90119-08MA1-00 is bolt #9 in the diagram above, it says a qty of 12 are required
90119-08M67-00 is bolt #11 in the diagram above, it says a qty of 2 are required
Still missing 4 bolts (red circles) to complete the total of 18 bolts (6 per cylinder)

...i don't know the part # but inquired a few weeks ago at the yami dealer. They might have some in the back shop so ask, but they are about 2.50 a piece and yes, are slightly longer than the other's. And as you may or may not know, those 4 won't work and aren't re-usable for aftermarket heads like R&D and Riva.
I'd say just order them from the dealer.

If anybody find out the part number please let me know, I had to install Stainles Steel bolts in those four holes.

I think head bolts are torque to yeild (TTY) meaning they cant be reused.
At least I know that its true for Ford and Toyota motors.

I bought all 12 short bolts new from yamaha, the problem is there is no part number for the 4 long bolts...so I cant buy them...
