    V7goose- Thanks for the response. Earlier in this tread someone stated if I was running on 3 cylinders the bike would only run in the 90's MPH. The only reason I ran that fast was to prove to myself that all 4 cylinders are woking. Normaly 80 is my top speed, but I do like to get there quick. This is another reason I think my problem may be in carburation and the black plug with only 500 miles on it.

    Rick. Before buying this bike I read many reviews of people talking about the power and smoothness of these bikes. My last bike was a 1995 Goldwing 1500 and it would run circles around my Venture. Something is wrong, this is not powerful or smooth. Condor. Checking compression is a good idea, but I don't have a gauge. Maybe time I bought one.

    I've already replaced the plugs twice and ran a can of seafoam through two tanks of fuel. I always keep the rpm's up but still chatters when accelerating.

    Before I removed the resistors from my plug caps I could not get to 100mph. So if 110mph is max then all my cylinders must be firing OK now? Could one of my carbs be flooding or starving a cylinder? The left rear plug was much blacker than the other 3.

    Mine is stumbling at Xway speeds 70+. At 45mph I would be in 4th even if just maintaining speed, but if I accelerate moderatly or hard it will stumble. I held it open in 5th and could only get about 110mph. I know it's not the way I ride it, I just can't figure out what's wrong. I bought it out of a repo lot and have no idea how long it's been sitting. 6 years old and only 18K miles, so it has spent a lot of time on the kickstand. This is why I'm thinking carb problems.

    The bike pulls so hard in first & second gear I don't think the clutch is slipping.

    Thanks everyone for your suggestions. Unfortunately nothing has worked. I ran a couple tanks with seafoam. I did a carb sync. I replaced the fuel and air filters. I removed the resistance in the plug caps and installed new plugs again. It runs stronger without resistance in the plug caps but it still stumbles under a load. I thought I almost had it fixed, but then I ran it in 35 degree weather and it was very bad. Maybe I do have a ripped diaphragm and when it was cold and the rubber contracted it got worse, just a guess. I may take the carbs apart this winter and rebuild them, but I can't seem to find a kit anyplace. This seems like such a nice bike I am just getting frustrated not finding the problem.

    Thanks for all the replies. My Magna has a redline of 9750 rpm's, so I know how to ride a bike that likes rpms. I have started it cold and checked all 4 pipes. They are all getting hot and it runs good at idle. I may be wrong but I thought out of sync carbs only affected the bike at idle. Again im not a mechanic so I wouldn't be surprised if I'm wrong. Even if it's not the problem a carb sync is a good idea. What is a good carb sync tool to buy? I seen a thread about Carbtune, is this still the tool of choice? I did check the air cleaners and they both look good, but I did not replace them. I think I will replace them and the fuel filter just so I can eliminate them as my problem.

    I also have a Honda Magna V4 750. I have never had a V-twin so I do not know how they react. My magna also likes to be high in the RPM’s but if it is not, it is just low on power not stumbling. I do feel the power of this bike in the first 3 gears. I have not ran the bike over 80 mph yet so I do not know what the top speed is limited to. I live in Grand Rapids, Michigan. What rpm’s does the rev limiter hit at?

    Thanks for the reply Cecdoo. Even if I downshift it still stumbles just not as bad. I was told these engines are very smooth and mine isn't. I constantly chugs under a load like it's not hitting on all cylinders. I'm 150 lbs and so far have only ridden solo with empty saddlebags. Sometimes it is better than others. Could the AIS be giving me trouble? It idles very good and pulls hard in low gears.

    Hello everyone. I am new to the world of Venture motorcycles. I purchased a 2004 Midnight Venture and for the most part, I really enjoy the bike, I have one big problem though. If I am cruising in a high gear and try accelerating moderately or wide open the bike stumbles bad. The harder I lag the engine the worse it is. I replace the plugs and checked the resistance in the plug caps and coils. All was within specs. The bike only has 18k miles and appears to be well taken care of. It is stock including the exhaust. I am not a mechanic, but usually I can fix things myself. This problem has me completely stumped. I have also ran two tanks with seafoam. If anyone has any suggestions I sure would appreciate it.
