I see. That's cool. I've never been to Oklahoma before. Do you get a lot of tornadoes there in your area?

My neighbor took the bike out for a ride yesterday! I couldn't believe it. I didn't think he would. He just went up and down the street a little bit. He said it started right up and ran well for the most part. Only thing he noticed is that in higher gears it wouldn't take full throttle or much more than 1/2 throttle or so. It would sort of bog or hesitate, etc. Makes sense as the higher gears put more of a load on the engine, so if there's a problem still that's when it would show up. Sounds like it's still not 100% right.

I ordered a set of O-rings for the intake boots. We're going to swap in the new o-rings and check the mixture screws on the carb and see how it goes after that.

Sometimes carb problems are actually ignition problems.... just saying I had an issue similar to that on a GS1000G where the "ignitor" box was shot. There is a test in the Clymer manual for it. I think you'll have electronic advance but if it's mechanical check that it is free & the springs are still functioning etc.

I think the O rings will help & yes you can test by spraying carb cleaner around if you like.

Now you have it running I would run a high concentration of Seafoam through it regardless. My guess is that the heat opened up some passages but they are still partially blocked. Make sure the Airbox is also sealed in all the right places. Sometimes you need to get new boots & clamps, run Silicone round the seams & replace the foam around the door & where the filter goes. If it's the type with a foam filter insert... replace it with generic Uni stuff (cut your own) and make sure it's oiled properly. The original stuff will slowly disintegrate.

The fact that it will run the same with airbox on/off is a big no no.... You must have airleaks somewhere for that to be the case.
