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 The previous version was outdated and no longer supported.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

250-500cc Checking crank when topend is off

Hey guys, Replacing topend on the wr300 this weekend and it looks good. No scoring, Piston even looked almost new with exception of a little carbon build up. I haven't ordered a new piston as I was going to take that in and have my shop check for tolerances to be sure and order the correct piston. My mechanic friend says I should also bring in bike to have them check crank out too. Seems like quite the hassle. Do you guys do this or just put in new piston and go? Is there an easy way for me to check it? Miles are around 3000 ish. I originally thought it was double that but was reading odo wrong. Replacing piston because Compression went to to about 30 psi. Like I said though the piston and cylinder looked almost new.
 
make sure no up & down movement in rod, a little from side to side ok I believe. can also check for movement/play at flywheel/stator. getting cylinder mic'd probably not a bad idea but personally I wouldn't bother until next top end just check nikasil for tiny cracks/missing plating. I ran my 300 for another 100+ hours with a small crack in nikasil-no dramas. tough old donks these things. im sure itl be fine mate, just bung a new slug in it & go hard!:thumbsup: disclaimer-I am no mechanic, disregard above statements in full
 
Check for up and down play, side to side is normal and required to operate. Replace the piston if the plating looks good and go ride !
 
Should be fine with those miles. Now I'm not so freaked out that you said it had 5500 miles on the stock piston. 3000 is a lot 5500 is :eek: and probably would be so down on compression it would not start.
 
Not just up and down check the motion throughout the cranks rotation
So one at tdc move the crank 90deg check up n down too if possible
Ive seen an oval crank pin that was good in one rotation an
Shot at midway point.
Should be fine tho no play is what you look for
