For some odd reason my carbs are running lean (plug is white/clean, exhaust pipe turns dark on the left side,,,,right side plug burns tan with slight color on pipe). I've checked for air leaks etc, everythings new, compression is 150 each side, valves set ect. That was with the stock idle/pilot jets...#45. At 4000 rpms, checking the marks I made on the throttle grip, I determined I was using a 1/4 throttle at the most. At 1/4 throttle the idle/pilot jet and the needle's taper, controls the fuel. There is not a lot of needles available, The V9 was too rich for my application in any position so I went the path of larger idle/pilot jets to increase the fuel. A larger atomizer could help but unobtainable for VHB's. I went larger until the mixture screws were almost in all the way for smooth idle. I still need to try a 62 or 63 in the left side, it still needs a little more gas. I may be twisted in my methodology, but after a month of various convoluted attemps at different ways this seems to work the best. Later, JU |
