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 The previous version was outdated and no longer supported.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

TE250 2011 VALVE SHIM QUESTION?

Hey guys,

I just got my valves shimmed, my mechanic tells me I will get another 200mls approx before it needs doing again, Does this sound right?
 
No. I 've only had to change out two shims in my engine in 12000 miles and 600 hours. Of course, I have a 450....but usually when valves need shims replaced in just a few hundred miles, it means that they are worn out and pulling up into the seats. At that rate, it won't be long before one of them drops into the cylinder.
 
A small tip to assist with valve and valve seat longevity is to use fully synthetic two stroke oil in your fuel at circa 150:1. at each refill. It acts like the old lead addative. it also lubes the top comp ring and as a side benefit stops fuel from going off.
 
It depends.
  • If the hard facing on the valve has worn down (dust or mud ingestion) then it will continue to wear at a rapid rate and need replacing (plus have the seat re-faced).
  • If it was only a minor shim adjustment it is due to normal wear of the camshaft lobe and cam follower.
Check the clearances again in 200 miles and you will know the answer for sure...

I've attached sample photo's below of good and bad valves for reference.

I've only had to shim the valves once on both my 10 250 and 12 310 and they get plenty of use.

I check them every couple of years unless the bike starts running or get's too quiet and they are always fine.
