Re: Little BSS cafe racer

A little of your favourite sealant is what I suggest; but not a silicone. I use Loctite 515 or Permatex No 4 hard setting. I'm doing a B25 pump right now and surfaced the steel end plate. It had some witnesses so I surfaced it. It only took a couple of rubs and it was good. It was soft and I was sur...

Re: tightening head nuts sequence

The threads should be clean and dry and NOT oiled as the tightening torque will be increased due to the lowered friction caused by the oil! Tightening sequence isn't so important on a single cylinder engine as it is on a multi cylinder engine, as a general rule you just need to tighten in diagonals...

Re: Little BSS cafe racer

Use a sheet of 120 grit wet and dry paper wetted with soapy water on a flat surface to fix those pump parts. When you have a true surface put the gears in the housing and run the lot over the paper and you will get the assembly down to zero clearance. Take a bit more off the gears so you have .002" ...

Re: B25SS exhaust pipe

I'd agree with Jeff K and sympathise with the purchaser.

Who ever is fabricating those pipes needs to invest in a 1/2" or more smaller center line radius tooling.

Very easy pipe to make; would be good if they were made from 409 or 304 stainless or even titanium.

Re: B25SS Burning Oil

It’s just a thought, but if the the crankcase breather pipe was blocked, might this cause oil to be burnt? I hasten to add that the engine is oil tight! No need to dismantle to perform a leakdown test. You will see how long it holds compression for/rate of loss and where it is losing- ring seal, va...

Re: B25SS Burning Oil

Rings usually rotate so the chances of the gaps aligning is not that great. I'd take that old beast out and give it an absolute caning for a few miles. Chances are the rings will seat. Try with a different brand of oil; that has been known to help. Really needs to be pushed for a couple of dozen rot...
