Hi Patrick,
that's good news about the exhaust manifold.
I just noticed that there is a new Marlin price list on their website that lists a Sportster E30 manifold and exhoust system for £775, ouch!
I am planning on a diy exhaust system to start with, but i'm not sure how easy this is going to be
I have bought the fuel swirl pot and both high and low pressure fuel pumps, so will persist with this design.
It will be interesting to compare results.
best regards
peter
