Hey guys hoping you can help me out. I've almost got a perfect race tune on my Keep Off 7 with buku clutch, medium/hot plug and 9886/41001 pipe set up. If I warm it up and make a few moderate passes and come back in it idles good and consistent. But if I try to really rip it and open it up and stretch its legs, as soon as I come back in and let it idle the idle is lower and weaker and keeps getting lower and lower until it dies after only 12 seconds or so, sometimes less time. The trouble is if I lean the LSN anymore and lower the idle a bit, it will come back in with a HIGH idle way to strong. So Im at the point now with the idle and LSN set just before it would idle way high and strong after a high speed pass and dies after 10-12 seconds ONLY after high speed pass. Correct me if Im wrong but it sounds like my carb is out of balance and I should re tune? It sounds like my idle gap is still too big in turn giving me an improper LSN setting. I'm not sold on that theory yet tho because I tried leaning the LSN more and dropping the idle but that doesn't even help the idle after a high speed pass it stays the same! That should strengthen the idle and make it more consistent but it doesn't , the idle would still get weaker and die out after a high speed pass its so frustrating. I hope I don't have any air leaks. I just ordered a new tank too. What do you guys think?
