Could somebody tell me what jets they put in the mikuni hsr 42 that are set up for mudmotors and do they change anything else on the inside of them? It will be going on a generac.
Thanks

Boat dr told me 165 for 35 with heads cam.and exhaust

There are a number of variables to that question... Where are you located, what size engine, is it stock, if not, what mods, light boat, heavy boat, etc.... Mine ranges from a 160-165 depending on what I'm doing.

Im in southern indiana and its a 32 generac with head work and gutted factory exhaust. Had the stock carb and it ran upwards to 4200 rpm but it was crap then i bought a used weber carb that somebody had on a generac but can only get to 3700 rpm its a 32 mm carb so i found a used 42 hsr from a harley that i may buy and wanted a starting point on the jets. Thanks for the replys

I had heard that you had to change the float just didnt know why and what kind
