• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Overheated my TE630

Well today I decided to check the clutch bushing/cup washers etc, so started the bike and left it idling in the driveway for 15 mins to warm it up before draining the oil.
Bad idea! The lack of air through the radiator caused it to boil and spray coolant up my wall from the overflow bottle.
Well at least the clutch bushing etc checked out OK.
 
Yeahhh, big thumpers make a lot of heat at idle with relatively low coolant flow.
Did your cooling fan not kick on?

Side note, it's about impossible to keep coolant in the overflow bottle on a 630, it just evaporates out. What's the level like in the radiators now?
 
Interesting, I rode 2 weeks in Morocco in temperatures in the mid 30's C (mid 90's F) and had no cooling problems. Overall I think I added a drop of coolant, most of my bottle went to top up the KTM's.

Different story when you're getting some air flow from moving and some real coolant volume flowing from being above idle.

Agreed. I still think the fella's got an issue, though, as I've had to idle mine for longer periods than I'd like (and longer than he had) and mine didn't spew (and the fan functioned as it should.)
 
My fan doesn't turn on when I idle the bike in the garage. I tested it and it turns when I plug 12v to it.
So maybe I have a bad temp probe. But I used an infrared thermometer while it was idling, and while the exhaust itself was up to 500F, the cylinder and head never got much higher than 120F or so.
So question, how long do you guys idle before the fan comes on?
 
i've never left mine idling long enough to find out, but it'll come on sitting at red lights on very hot days, so I know it works.
 
Yeah I'm sorry to say I'm not sure how many minutes it takes for the fan to come on myself. I've idled it long enough to do that several times, of course, but have never timed it. I'd say it's somewhere in the 10 minute range, though.
 
Thanks for the input guys. I didn't even think to look and see if the fan was operating. Guess I'll give it a run tomorrow and make sure its operating OK.
