  • 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 The previous version was outdated and no longer supported.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 WR 300 compression

Keep in mind that with compression tester they vary wildly in read out. In other words what mine might read on my bike someone else's gauge will more than likely read different on the same bike. Best thing with a compression tester is to use it when your motor is new to get a base line and then use it to see how much compression you lose over time. To ask what it should be can be bogus since each of our gauges more than likely will give different readings.

Also when testing you should hold the kill switch on, throttle wide open, air filter removed and kick it 5-10 times.
 
I think I'm going to run it this season and see what happens! I'll keep a piston kit and gaskets on the shelf just in case...........:thumbsup:
 
I would start measuring the ringgap and see if it's within tolerances, visually look at the piston and bore chamber itself for blow by, measure the cylinder and piston/wall clearances...things that you can note down as a baseline if you are indecisive on whether to do a top end.
Do the 300's have an hour meter? If not buy one and slap it before you do the top end as that is the most accurate way to guage the life of the motor.
Also depend on how you ride, how often ect...your average trail rider can go up to 150hrs before a topend vs a racer who will probably go up to 40hrs.

If everything is within tolerances but there are signs of blowby, just replace the rings, flex hone or use scrotchbrite to deglaze the bore.

#5 of compression loss for a 300 is nothing.....if it were a 125 and you were competing for points maybe.

It'll be easier to kick!
 
Thanks for the replies. I'll surely enjoy the lighter kick when it's 90 degrees and I'm tired from picking the bike off of the ground all day long....:D
