engine mounting bolts - 72 chamb - 17-02-15
I'm fitting a new belly pan to 2000 plate 600.. i need to use the engine mounting bolt but when i bought the bike it had crash bungs on it. I have took these off but do not know what size bolts to replace them as the crash bungs needed longer ones..
any tell me size and length needed..
Thanks

An engine mount bolt is pretty important part. If it was me I'd order OE replacements to be on the safe side.

ive only got the bottom front on mine not the top, cant get all 3 bolt holes to line up.
seems pretty strong not shifted even putting the bike on the rear wheel and hard ish landings.

Do you know what length they are as the ones for the cras bungs are far to long.

I have just recently had to do the same thing, I bought M10 x 100mm bolts and M8 x 100mm, stainless steel from ebay, had to buy 4 so I've got 2 spare of each if anyone wishes to purchase them for a small fee.

The M10 bolts are to replace the bolts where the crash bungs were and the M8 are to replace the bolts below the bungs.

Thats brilliant....thankyou
Re: engine mounting bolts - Jamieg285 - 18-06-15
Did you have any issues fitting the M10s?
I an in the same position, needing new bolts to replace the longer crash bung bolts. I borrowed the OEM bolt from my old bike and went to the local bolt shop, who told me it was M9, and would have to be replaced with OEM.
I didn't think M10 would go, but will be happy to be proved wrong and save £10 on a pair of bolts.

been in simlar position buying bolts recently......one thing i learned, be aware not all bolts are made equal, they all have different properties and will have been chosen for their purpose when the bike was put together, i have in the past purchased bolts that were not OEM but i made sure they were the same material and grade i.e. 8.8, 12.9 A2, etc....there are international standards the allow you to usually detemrine the type and grade of a threaded fastner....

When it comes to parts like engine mount bolts and suspension linkages i would be tending to side with OEM, i don't know enought about the material physics and properties to make the correct informed decisions....but thats just me - i am a little OTT sometimes!

Hi anutz, sorry to hijack the tread, I have a lot of rusty bolts and want to replace them, any chance you can post the sizes and threads and grades for the ones you have bought? And from where?
