Hey guys new here. I have been looking here and else where for answers for awhile and haven’t seen the same situation I’m in really. I have a high mileage rincon (11,000 miles). It had the top end gaskets done before I got it. I’m having issues at higher rpm which i have seen info on but not on a high mileage machine as far as I have read. Right before it shifts from first to second and again when it shifts from 2nd to 3rd I have to let off to half throttle to shift or it will just keep missing. Before I rebuild the front end with bearings, ball joints and tie rods. What do you think this is? I want to get this problem figured out before I move on. Once it shifts into the new gear I can give it full throttle with lots of power and no hesitation until it gets close to shifting then I have to let off again.
