I'm sure this is true if one doesn't let the bike run long enough to get the engine and exhaust system hot. Ten minutes or so of running should normally be enough to prevent any rust from forming. As proof, here's a picture of my bike's original exhaust still on the bike after more than 43 years with zero rust. Ed

Thanks guys. I already had some stabilizer ready to put in the tank. Filled it up and put the stabilizer in today and went for a quick ride to cycle it through. I'll top up the tank and drain the carbs when I put the bike up on stands this week.

Been asking around here in Germany and it seems that an inline filter may be more of a US thing. It appears to be mostly two-stroke guys that use one (stakes are a bit higher on a 2-stroke). I imagine it's down to fuel quality. I know my Dad bitches about the fuel up in the Yukon, not in the states but still North America. It would be interesting to hear from anyone based in Europe. It may just be that all the guys I talked to over here are just a bit slack :)
I did talk to one of the neighbours about putting the bike away for winter. He's been riding and building bikes for a good 40 years and said he just puts in on stands and shuts the garage door.

One thing to be aware of.....

Many years ago I put my bike in my basement over the winter so I could have a warm place to work while replacing the lower fork tubes. To ensure I did not set my house on fire I removed the fuel tank and drained the carbs. In the spring when I took the bike outside and reinstalled the fuel tank the "T" where the fuel line from the tank attaches to the carbs leaked fuel. I was very annoyed and tried to find a new "T", but was not successful. Meanwhile since the "T" now had fuel in it that fuel apparently made the "T" swell just a tiny bit so it no longer leaked fuel. That was 13 years ago and the "T" has not leaked a single drop since then.

So if in the spring you find that the "T" leaks fuel give it a couple days and it may stop leaking. Ed

The petcock has been replaced and the carbs are drained. Now I can get on with some other stuff :)

Found an original KZ750H exhaust for cheap:



Only one significant dent in them:



I pulled the baffles out and it looks like I'll be making some new ones this winter. Does anyone know of anywhere that does repro KZ baffles? Seems like it would be something a lot of people would need.



Anyway, now that the mufflers are empty I'm trying to find a place that will rechrome them. Wrote to a place in the UK earlier, still can't find anyone that does it in Germany. If it's too expensive I may just get them done with Cerakote chrome - doesn't really look like chrome but should still fit in OK with the rest of the bike.
