Had my 25K miles, 85 venture for about 6 years, it never ran right - it would cut out at 6200 rpm, spit, sputter at full throttle on excelleration, I know it needed to have the carbs cleaned but I didn't want to spend the money. I just forked out over 200 bucks to clean the carbs, new plugs, wires, now it hesitates and doesn't go over 5200 rpms at full throttle. If I don't have it wide open I can reach redline in 1st. 2nd gear tops out at about 4500 rpm. Mechanic claims it is not the carbs mainly because it goes great until 5200 rpms ? I'm frustrated - I don't know how to fix the bike myself yet - IF it was a carb problem at 6200, so why not a carb problem at 5200 ?? I've already paid the bill, don't want to invest more money. I feel like I should have just left it alone if this is as good as it gets. Any ideas ?
