B pipe manifold install

[bored&stroked]

So I read the instructions I found online, and it mentions putting the top two middle bolts in first but doesn't mention anything about tightening them...Am I really only tightening 6 bolts and leaving those top two middle ones loose? I can't find any way to turn and tigheten them once the manifold is installed.

Snug those Two Bolts (or buy Waxhead's awesome Bolts ( https://www.waxracingproducts.com/products/small-head-b-pipe-bolts ) until you can just slide the Manifold slots under them.

Then start cross-torquing all Bolts.

You will need to grind an Open End Wrench to be able to turn those two OEM size Bolt Heads.

If you use Waxhead's Bolts, then a regular Wrench will fit.

Different wrench fit better, and grinding made it work. Graci.

The wrench that comes with stock Yamaha tool kit fits good
