I swear, I was on the damn thing all weekend (except when I got off at the sound of thunder!) It's going back in tomorrow to open up the jets a bit, off to the vinyl shop on monday for a new seat!

Alrighty, Shes pretty much done.
New Clutch went in today.

One thing that is limiting it really badly (wont pull over 5k) is the muffler.

I'm now looking for one as cheap as possible!

Another good place to ask your question is on this U.S. site, especially for thumpers.

Next question: Spark Plugs.

Should she still be running the factory spec plug?

I hear you. I picked up my GB400 on Friday, and I have been looking for every excuse in the world to go out on it ("No dear, I'll be glad to pick up some milk, I'll just dart off to Featherston for some...")! Even the ride back from Palmy at 10 degrees didn't put me off. What fun!

I never get tired of riding The GB Just this morning I tagged a trip around the Miramar peninsula onto my commute, I've had this one for 4 years and it's still fun to ride.

No wonder people are still hunting for these old bikes!
