I have noticed a lot of people alluding to problems on the 94-96 600 twins w/ pipes specificly when you run it in their powerband around 50mph. Is there anything that can be done to provent problems when running below 60 and over 35?
I always run premium and haven't had a problem yet but never really hold it inside those ranges but have several times for short periods.

Most people that have problems with twin pipes, are only having problems because they are not jetted correctly, or clutched to match the pipes.
I have a set of twin pipes on my Vmax 600 and they run great.
Just because you toss a set of pipes on a stock setup doesn't mean it will perform better. You must cover all areas to make them work correctly.
If you are adding the pipes for top end performance you will gain in that aspect, but if it is torque in the mid range, you will probably not achieve what you are looking for.

The pipes have been on the sled for the last 4 years that i have owned the sled, and I have been very happy with the performance, i am just curious if there is something i should do the prevent a possible problem in the future. The previous owner installed them and set it up, so i assume everything is alright, i have burned the engine down from un-syncronized carbs the leaned out a cylnder yada yada.

You can tune the carbs to minimize that bog around 5-6000 rpm part throttle but you'll never fully get rid of it because it isn't the pipes, we determined. It's something in the porting / cylinder head combination of the 94-96 twins. Pipes make it more pronounced, but are not the root cause.
I have GYT twin pipes and no matter what fuel, needle shape, needle jet, pilot and main jetting, or carbs we tried we couldn't get rid of it completely until we had Full Power Performance change the cylinder port and combustion chamber shape to their specs. Must be something to do with the stock cylinder port velocity at that RPM, it's inherent in the design.
Run good fuel and you shouldn't have a problem but best bet is to clutch and ride it outside of that range if keeping the stock configuration...
