I am currently putting MVA heads Andrews 60 series chain drive cams and SE 11.1 comp piston On a Dyna. My question is this everybody wants to go to a larger throttle body and most replies say dont spend the money how about the stock throttle body with the high flo intake? Or what will work goid with my set up?

Get a 50mm TB off of a touring bike and use that. No need to go any bigger on a 103".

Thank You! I was told today on the HD tech line that it is a fifty on it? That sometime after 06 they were upgraded I forgot exactly when he said? I guess when I get it apart and it is a 46 I will then change it. I had asked the tech what was the diff between the se 50 in the catalog and he said it was the same as mine but for 06 because the 06 and prior was 46mm.

Dynas and Softails have 46's. The Touring models have 50's. What you were told on the HD tech line is wrong. Prior to 06 they were 44mm Delphi units.

Actually pre-06 was a 40mm bore. Many people mistakenly measured it out where the backing plate bolted on but the actual bore at the butterfly was 40mm.
