Mikuni on an Ironhead

4 posts in this topic

Has anyone on here ran a Mikuni on an Ironhead? I have a VM42, which I know is a bit large for an Iron, but I want to try and run it. I have a polished Branch manifold behind it. I not sure what it was on before, so I'm taking a guess that it'll need rejected. So I was wondering if anyone on here has ran one before, and what their jet sizes where. I'm looking for a starting point.

81 Ironhead

VM 42, Branch Manifold, K&N Intake, P Cams(Pulled the Q Cams), Drag Pipes( Lollipoped for Back Pressure)

Thanks for any help.

I've read on another forum I'm on that the VM38 works great on a stock Ironhead. Don't know what jets you'll need but that VM42 shouldn't be too much of a stretch. I'm running an S&S Super E on mine with good results but I have a lot go fast parts in her. Guess I could PM you the addy, don't know if mods here would approve of me putting direct.

BTW you'll like the P cams much better than the Qs.

Run it with whatever it has for jets in it now. Should be close enough to get you started. The 42 is a bit big in my opinion but should be OK if you remember to roll the throttle on rather than whack it open. I run a 38mm TM on my Shovel and throttle response is awesome, no bog, no flatspots. The only thing you'll need to check is that it has a gravity feed needle and seat, otherwise it will starve for fuel under load.
