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 The previous version was outdated and no longer supported.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

2006 TE250 - Lock at TDC?

Husqvarna
A Class
I've got a 2006 TE250 with an Athena 300 kit installed. I checked the valves and installed some new shims about 40 hours ago. I am going to recheck them this weekend while I do the oil/filters but I would also like to do a compression test and leak-down test. I've got a few questions for you guys...

1. What compression should I have with this setup? How many kicks should it take on this bike? Does the automatic decompression effect the reading?

2. How do you lock the bike at TDC? I do not see any mechanical apparitions to facilitate this. On my KTM they were nice enough to include a bolt to lock the crank in at TDC, which makes doing the leak down easy.

Thanks for your help and knowledge!
Cheers

No different than your Ktm- ADC does effect, with it in place you should be around 115. based on what Dave Hopkins Says... :notworthy:

There is no TDC locking crank bolt on the Husky like on the RFS motor. Best use for that bolt that I found was disassembly when redoing top end. I didn't use it much otherwise.

good luck

Thanks. Dave built my RFS motor, he is the man.

So how do you hold it at TDC to do the leak down test at 100psi? Keep it in gear and lay on the brakes??
 
remove the plug, v/c and put it in gear and spin the back tire to get to TDC marks. then, remove the cilps and slide the arms over. remove the shims. then if the piston goes down to BDC who cares, doubt it will in gear with the brake on. check for clearance on all that before you go full scale as i rarely go into these motors for obv reasons and am going from memory. leakdown is for percetange of pressure escaping and by what, not volume. piston can be anywhere as long as vavles are closed. might have more blowby at BDC due to taper. piston while it's running also helps "close" the valves from compression.

do you have factory specs or just curious? personally if it aint smoking, using a ton of oil, valves aint sucking up etc...i'd just ride it and not pay too much attn to "readings" on a dirt bike engine. :)

Just curious more than anything. Its that time of year that I enjoy hanging out in the garage with a cold beer and check on and maintain the dirt bikes. Doing things like repack grease, change suspension fluid, check valves, compression, leak down, etc... Its my idea of fun and since I cant ride its the only fix I get. :D
 
been there...as in knocking over a bucket of nuts-n-bolts to i'll have something to do/make/go get from home depot etc...:p just dont get discouraged if yer #'s aint all that hot.

enjoy gettin' yer fingernails dirty. :)
