Good deal Jim, techron is great occasionally for a deep clean , man .........I'm just
about to ditch a ZG screen in favor of an MRA touring from TwistedThrottle on my
1993 .........the ZG (came with the bike) was still a bit too low and gives me major
wind blast in the chest and of course I made it worse with higher VFR bars on it.
It's possible though my ZG is not the touring "spec" one and it's on a Gen 3 bike
which sits slightly different anyhow

Look forward to seeing yours ...etc & comparing notes

Mine was stuttering bad during pilot circuit (1500-3000 rpm +-) but is ceased after I synced my carbs along with a rock steady 1050 rpm idle.

Then the stuttering began reappearing even though my idle was still solid. I went to re-sync, but they were close enough to not bother, but I did find that one of the port caps had a small tear in it causing a vacuum leak on #2. After I fixed that the stuttering was gone (again).

Look for vacuum leaks, even small ones. And sync your carbs.

This is interesting.... I only just read this.

I bought a 95 CBR 1000 a few weeks ago and brought it to the honda shop and had them give it the once over. They cleaned the carbs and did some other things. The bill was around the $700 range. I notice that at the lower RPMs it does stutter some. I know they did test ride it after and said it ran good. So I'm wondering now if it is pretty common or I should bring it back, there seems to be mixed advice on this board about it......

I just switched to NGK 8's instead of the 9 for a hotter range to see if it would help. So far no sputtering. To early to tell, I may have fill up with good gas somewhere.

Just don't run them below 3k. Problem solved as long as they don't shut off at stop lights. lol..
