camatv Posted January 15, 2011 Report Posted January 15, 2011 those are jet ski carbs ( and old ones at that) they were designed to run with a pump i believe. they probably need actually tuned why do you think its to lean? the stock carbs would be jetted to about a 320ish depending on needle stock carbs needles are very lean on the top that is they let a LOT of fuel past teh main at wot. you would need to jet those carbs you have better and that may require a needle and a float neelde/seat change. i would also suggest leak down. if you change your jetting a LOT and it still runs the same something else is wrong.

30years Posted January 15, 2011 Author Report Posted January 15, 2011 Im just throwing this out there since Im not too familiar with mikuni's. Are you shur they arent meant to run with a fuel pump? Did you buy these from someone you was running them on there banshee? This may explain your lean issue I just bought the carbs from tdr racing assuming that bigger carbs would help with performance. Guess i was wrong. I'm gonna go ahead and do the tors removal and do the idle screws and throw the stockers back on and see how she does. Thanks for all the input!!! Quote
