Re: Make a FWH brake better ?

Has anyone changed the profile of the cam? It has the most elliptical profile of any cam I have seen on motorcycle drum brakes.

Re: Wanted: Oil filter for 1936 4F

Hi Paul,
Thanks so much for the follow-up. I was leaning towards that filter, and was trying to get hands on one to measure.

Wanted: Oil filter for 1936 4F

Hello Arielists,
I need to replace the oil filter element; part no1584-33.
Can anyone lead me to a supplier?
Do owners make a replacement element (IE modify one that is available)?

Cheers,

Re: B-TH magdyno

I installed a BTH on a Super Rocket in 2008. I have hidden the coils under the "ski slope".
Very happy with the performance; easy starting and smooth running engine.

Re: 1 Inch tubing in the Netherlands

What John said.
