Gsxr 600 srad surging at constant throttle

Have a look at plugs, caps, leads and the like. You could also try checking your connectors, some of the plugs can corrode which can lead to a poor connection.

Sounds like you are going to be checking a lot of stuff.

A mate here has a learner bike and he complained that since he had it, it was always a bit gutless even for a 125. While chatting away as he as getting ready to go recently I noticed that it was arcing from the plug cap to earth. Anyway, after fitting a new plug cap it runs really sweet. This has taught me to check the simple obvious things first, even new plugs can fail and a dodgy HT lead can give you trouble.

Good luck finding your gremlin, I am sure that you will in the end.

No its got a standard airkit setup, just k+n filter. mileage approx 32k.

Ive had a look at that stuff before, but tbh unless it looks broken hard to know you havent got something dodgy going on. Need to get out and try more things but just dont know where to start.

just fixed the last thing i knew was wrong with the bike, the fact it wasnt sealed properly between end can and exhaust manifold. A quick ride wasnt quite enough to say whether thats fixed it but i think not..
