Title: 42mm Mikuni HSR
Post by: truckintyler on October 23, 2019, 09:31:08 PM
Would a single 42mm Mikuni HSR flat slide be ok or too big for a command twin 44ci with a cam and port job?
 Or would two smaller flat slides like Keihin fcr be best . Not sure which direction to take .

The engine that Zach Kerber built me had 2 42MM mikunis on it.   I think he sells a kit with the intakes and carbs.   Check his website out.

What would the port work be like? Also what rpms? Cam?

just ordered the MWSC 6000 cast cam kit , rods and flat top pistons , rpms ?- this is my first open engine 6000-7500 rpm ?.
 Head work -- pretty much will be an amateur job just cleaning up the ports ,  nothing like the port work you do micheal.

In that case the carb is more than likely going to be way too big. Try a 36 or a 38 instead. 36 would probably be perfect
