Where can i get 3 replacement SS bolts that connect the head pipe to the manifold? (Factory B pipe btw)
the end of the B-pipe screws have a machined tip. ...they are inch sizing 10-32 ..(pretty close to metric M5) .....if its an old B-Pipe someone may have re-tapped them at some stage.
I think your talking about the water screws Knoxie. I am just after some SS bolts that connect the head pipe to the manifold
ha ha ...yea ...should read the post properly ... they should be M10 x 1.25 pitch (metric fine) ...not sure how long.
In case anyone ever needs to track down replacement bolts you have two options. 1. get the m10x 40 bolt from the bolt shop ($1.50ish per bolt) and grind the head down so that it will fit a 15mm socket (17mm usually). or 2. Pay 18.50 per bolt plus freight from GP enginering I can not find anyone in NZ that carries a metric fine m10x 40, 1.25 pitch at a reasonable price ..
take a sample to steelmasters in penrose they have the biggest selection of stainless. or use an allen key head...
ive tried to get metric fine (like M10 x 1.25) from the east tamaki Anzor and they didnt have it ....maybe better selection at Albany one?
they are 1 mm pitch not 1.25 so it hard to get them in stainless when you pull the stock exhaust off a yamaha you eill have 2 10mm nolts with 12mm heads on them they will fit in you just need one more
