Yeah damn california and their emissions laws... My father was the original owner of the bike and he parked it back in 2004ish. Due to bad cam chain tensioner and a CDI. He bought a 1100XX so the hurricane just sat until I rotated back from Germany and was moving to Oklahoma and needed a project. So I stole his old bike The speedometer stopped working back in like 1995 or 1996 with 66,500 miles. I surprised it still runs These are awesome bike and I would recommend it to anyone looking for a project as long as they don't mind the carbs and the vacuum lines...

Yeah I just bought a new welder so I was just going to cut the pipe and then weld it shut but then I thought to myself that if I ever sell the bike and the owner wants all the original emissions stuff I shouldn't tamper with it. Obviously I didn't have any gaskets for them so I just used a good amount of gasket sealer. The type I used I really like and have used it on a lot of metal to metal surfaces and have had no leaks with oils of fuels. It is made for differentials and hubs. Specially designed for synthetic oils. It is silver in color. Some of the best I have used. Of course the copper sealant is always a good choice. But this is what I had in the garage.

Hi, guys, i've bought such machine few days ago, not w/o problems, and among others it has simptom, like described here. It runs not bad, but when go on rpm>5000 on 5-6 gear a few minutes it became slow, and at least it can switch off. It's look like the fuel ends. For first time i decide that the reason is in fuel valve, because vacuum tube on it was in bad condition. I changed it , but no changes in engine work. looking above the tank i saw that few of the vacuum tube (from right carb, must plug to one of valves) are unplugged. More than that, one of the valves is missing. Could it be from this?

By the way I went today about 15 km, 100-120 km/h, it run so &so, not so bad on this speed, but when begin to go faster, it suffocates, and when accelerate for a short time - it runs, but when accelerate on 1,2,3,4, gear, it also begin to die, and can switch off. I closed this tube, but nothing changes. I will grateful to any advice...
