Anyone know why I have this little bottle instead of a coolant tank? I bought the bike last week and it runs like a champ and never even gets close to being hot but I do'nt know the reason behind it?

 

I'd say the original coolant overflow went kaput somehow and the previous owner, in a spate of creativity, rigged that up. Or he was a fanatic about weight savings. Any other oddities on the bike? I'd start looking for other examples of creative use of everyday objects.

 

I haven't noticed any thing else out of the ordinary. Is it safe for the bike?

 

If it hasn't been overheating I wouldn't stress. But keep an eye on things for sure.

 

Was it secured to the frame? Chances are it's safe...until your bike overheats and the bottle goes boom. Which, though possible, isn't likely. At the very least you should secure it so it doesn't bounce around, but getting a stock overflow wouldn't be a bad idea.

 

No it was just laying loose in the void where the stock tank was. I'll just zip-tie it to something and start looking for a stocker, thanks guys!

 

Better yet find a real expansion tank with this hose on the bottom and a vent on the top.
The air need to escape or it will over pressurize and blow/leak.

 

Since I will likely never use mine again I'll dig it up this weekend and ship it to you.
PM me your address and I'll ship it out asap.

Why won't you put it back on? What have you got on there now?
