I ordered a Clarke 4.7 Gallon tank for my 650L last Sunday from just gas tanks. I also ordered a 55 pilot jet from thumper talk on Monday. I had installed a dynojet kit last summer but I was never happy with the off idle performance. Both the tank and the jet came on Wednesday and I got around to installing them today. The tank install was pretty easy and the pilot jet was easier still. I hate that it is so stormy here right now and I can't take the bike out for a spin. It's like giving a kid a Christmas present and not letting him play with it. I'll post pics of the bike with the new tank after I get some new batteries for the camera.
