  • 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 The previous version was outdated and no longer supported.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!

Radiator Cap

So I am thinking that my overheating problem may be because of my radiator cap not holding pressure. I want to get an extra cap, but don't know if there is a certain type to get. Anyone have an extra they wanna sell me, or know where I can get one before next Friday?

I had a GasGas that overheated. After ruling out every other possible reason it could be overheating, I put a KTM radiator cap on it that was rated for higher pressure. Problem solved.

Unfortunately I don't have a radiator cap for you, but good luck!

Called Dan at Motoexotica. He's shipping a new rad cap today. YAY! Cant be Friday fast enough for me.
 
subject to varying opinions
My 08TXC450 has a KX80 1.8 bar cap (26.46psi), CV4 silicon hoses, high pressure cross over tube, GFBN OEM German automotive Tee fitting, with the stock catch tank and filled with Maxima Cool aide (pink stuff). I ride alot of very rocky technical crap and rarely see any steam,,,,PS the higher pressure does stress the water pump seals but mine is still hangin tough. R
 
Ditto on the higher pressure radiator cap. There are both a 1.6 and 1.8bar cap available for the KX's, just make sure your hoses and clamps are in good shape along with an aluminum Y and re-inforced cross-over tube and you'll be holding fluids in better.
 
Well I still had the overheating problem on the Baja trip. George and Mike and I were trying to troubleshoot it, and mike suggested a pin hole leak on one of the radiators. I discounted that because I had never seen any steam or fluid come out of them. The temp was cool, so the bike never really went above 120 - 130 Well, the last day as we rode the beach into San Felipe my bike began to heat up to about 150 and reached 170. I stopped, and saw steam coming out of my left side radiator. I guess Mike was right. I'm shipping the radiator off to Myler's today.

Kelly hit the nail on the head...I have a Rekluse that was working the hell out of the clutch. Add miles of soft beach sand to that equation and the fact that I boiled out most of my radiator fluid and you get 300 degree temps**************************************** Anyway, I was thankfull to have the uptite Y and updated crossover tube as I'm sure thinks would have either melted or popped.

Make sure your not running lean and try not to use the clutch a lot on overheating situations.

my recluse has added some overheating issues , mainly on hills ,tight single track is okay its just when the clutch is under pressure

I don't think the Rekluse is fine tuned enough for tight singletrack type use on the HSQ's personally. I have an 04 KTM 525SX with a rekluse that is a major single track sleeper. I haven't seen a guy yet be completely taken by it's ease and grunt speed through tight trees.

However with my TXC510, it has been severly overheated due to the rekluse during a race and it never goes to full lock up early enought. Regardless it still launches the front in the air right off of throttle if desired, but it's got too long of a duration from initial lock up to full lock up. I'm running 9 tungsten balls and still want better lock up off the bottom.

Anyhow, I have found that using engine ice, Uptite Y and stiffer rad cap has helped my hot running issues for the time being
