Aussie Quad Racer Posted January 20, 2004 Report Posted January 20, 2004 yes that looks like a mikuni vm34 with a powerjet. The power jet works well with engines that are running large sized mains. Of cause you will have to make your main smaller when running powerjets. In mikunis tune manual it says that WOT should draw 3/4 fuel from main and 1/4 from power jet for best operation. I was playing with different size powerjets in my mikunis and had to change emultion tube with the powerjets to keep the midrange throttle openings correct Quote
