Boiling coolant and gas?

Canyon (asdf38) had a similar problem in August ( http://www.kawasakiversys.com/forums...ead.php?t=1264), but it didn't seem like there was any kind of resolution, and I didn't find any other posts about this....

A couple weeks ago (when the weather turned a bit colder - you can feel the nip in the air and know it's Autumn), my Versys started boiling / bubbling the coolant in the reservoir and the gas in the tank.

None of my local motorcycle friends seem to have a good sense of what it could be and I may have to take her in to the stealership. I'll try flushing the coolant this weekend. The level is fine, and I was hoping it wouldn't need a flush so soon...

She needed an oil change anyway, so I did that this past weekend, and spent some quality time cleaning her (I'd rather ride than clean, so just Simple Green / Plexus the bugs off and then shine with Pledge as needed and only thoroughly wash every couple months). Her fuel vent hose was kinked and smushed, so we straightened that out last week, but she's still boiling / bubbling her fluids. A friend who works at the Ducati dealership had a Duc boiling its gas last week and the problem was a clogged vent hose, so he suggested I take a look.

Also, I do have one gold and one blue header pipe - just noticed that a couple weeks ago. I just thought one was dirtier than the other til I did some Googling and found that it generally (?) indicates that one cylinder is running too lean...? I also found one forum post that suggested the blue/gold header pipes meant the throttle body timing was off. I don't even know what throttle bodies are (but I know the Versys' are made by Keihin!), but synching them sounded like a pain in the neck and something I'd rather pay someone to do.

I'm also in Salt Lake, like Canyon. We're at 4500 feet and I've ridden up around 8000 to 9500 feet (local mountains) loads of times - could that be contributing to the bubbling / boiling or the blue/gold pipes?

Any thoughts? Other things to look at / try before taking her to the dealer? Thanks!!!

Change your coolant, and check your radiator cap. I had the same problem periodically. My water pump was also leaking.

I retorqued the water pump bolts, changed the coolant, cleaned my cap... and it's been fine since.

There has been a lot of talk about the bluing header. Some will tell you it's a lean condition, but I think it is a result of the different lengths of the headers. I asked my mechanic about it when I had it in for a throttle body sync and new rubber a few weeks ago... and he concurs that it's a result of the pipes being different lengths. My bike tends to run a little rich, and the throttle bodies were not out of sync very much... so, I attribute it to a Versys phenomena. I have not seen too many Versys, but of those I have seen, they all had a blued rt pipe.

Thanks! And yes, the right pipe is the blue one. Cool. I'll flush coolant, clean the cap, and not worry about the pipes.

Thanks again!

There is a very convenient drain plug right at the bottom of the water pump (rt side). Easy as pie to change your coolant. Have to remove some plastic, and bend the metal rad cap guard back to pop the cap. Fill it to the bottom line.
