Hay Brian, are you on the ST-Owners group? So what exactly have you tried to fix it?
I like to try all the easy things first before doing the big projects, but I think your problem is in the carbs. You can replace the air filter, inspect the air intake lines, run it around the block with the cap off, and run two tanks with seafoam thru, but if that does not fix it, I think you will have look closely at your carbs if you want to fix it.

I was trying to determine if you were having a fuel delivery issue. The bike will consume greater quantities of fuel when riding as opposed to stationary, so it may not develop with that test. However since the issue didn't develop, then I would assume the coils are functioning properly. Provided that you allowed the engine to completely warm up, as weak coils show their signs when hot.

I did not do the full throttle test, I didn't have time to take it out on the road. Thoughts. On Mon, Jun 25, 2012 at 1:15 PM, Allen Thomas <althomas...@gmail.com> wrote: What year? Is it carburated? If you keep trying to rev it higher will it loose speed and eventually die? It sounds like a restriction in the fuel line.

And thanks for being that friend! I try to be that friend back when I can. My ST1100 runs great under 6,000 rpm, but when I get on it to pass someone or just playing around and the rpm's 6,000 or so it bogs down. Kinda like when a bike is cold and you give it to much gas, but it does this every time. If I shift and bring the rpm's down under 6,000 it stops bogging down and runs normal. Any ideas?
