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 The previous version was outdated and no longer supported.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

what are the tale tale signs to rebuild the top end before causing more serious problems? how about a very faint ringing sound while in the power band?
 
Compression test comes up low is a solid sign.

I just got 92.4 hours out of my 165 kit before re-ringing it. It was still running strong, I just felt guilty, so I had to do it.

very faint ringing sound could be anything, and doesn't point to anything in particular.
 
That's right...ringing can be jetting, vibration or pinging from low octane gas.

Usually when the bike is hard to start and won't idle then it is time to look at the top end.
 
good. just put the lectron yesterday. just a jaunt down the driveway so far but idle s great. we'll see if the ringing persist soon. just wanna make sure i don't blow it up like my buddy did his ktm 200. he's looking at a $1000 rebuild.
 
I had a ringing sound like that for a while, it ended up being a broken pipe on the inside of the rear mount where I couldn't see it until I had the pipe off.

Later,
 
Faint ringing sound is very often the top shock lock ring has come loose and is "ringing" around!

Compression check against new, and engine hours are a good thing to go by.
 
Get an hour meter when you do your next top end.

Symptoms of requiring new top end:
- Lack of compression : easiest is to crank the motor by hand using the kickstart..if it's easy to kick by hand (or you don't feel a strong compression stroke), then it's time.
- Piston slap: hard to hear when started but if you pull the head off and you push the piston side-side and the crown touches the cylinder wall, it's time.
- Gradual loss of power: could be carb but likely gradual loss of power is due to loss in compression.

Of all the symptoms, piston slap is the most worrying as the likelihood of a seizure is more pronounced and it is doing damage to the cylinder wall!!

If you are worried, just do a top end rebuild and enjoy riding it rather than worrying (that's what the hour meter is for :P )!!
