Coolant Overflow needed?

13 posts in this topic

Would taking this thing off hurt anything. The YZ doesn't have it and I never kept them on my atv's that I raced. It looks like something else to work around to me.

YZ's were not intended to crawl along on single track in adverse conditions either..... if you ride primarily MX or wide open stuff then it would be a consideration but if you ride off road on pack and carry type stuff or race harescrambles I would leave it on there...... many of time I have overheated and it's nice to know the recovery system is there while your buddies on the YZ's are emptying their camel backs into their radiators :applause:

Great idea! Then if you get lost in the middle of nowhere and happen to run over a turkey you can keep the meat really moist!:applause:

I agree. Thats pretty sharp.:applause::eek:

I never really thought about it overheating. I have never had one overheat that was liquid cooled. I do plan on racing a little. I always stripped the quads down to the bare ecentuals(sp?). I didn't know if you did that with a bike or not. Since we are on the subject, does the YZ cam lean out the mid range and give a smoother pull to the top or am I wrong?

Thanks

The YZ cam makes the power hit harder/lower and pulls harder to the top. Its more agressive than the WR or YFZ cam. Apparetly the 03 YZ cam is most aggressivist :lol:

Do you just buy the cam or are there other things you need to do the swap?

The store here shows the 04 YZ cam for $102. I guess that one would work?

You just need the exhaust cam. Some need to re-shim, some don't.

I think the overflow has something to do with environment also guys, I also looked into moving mine to make room for an additional fuel tank which i would lose the overflow bottle.....

What is that you have on top of the baster bulb? I would guess it is some kind of vent. My buddy is looking to add a bottle to his YZ250 2 pinger and that mod just may do the trick.

That Turkey baster looks like it's glowing like a Star Trek Warp drive.

Beam me up Scotty. :bonk:
