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 The previous version was outdated and no longer supported.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

HI all,

just came back from a ride and found out that the Airlid was not proper in place as you can see on the picture.
Through that Gap was Dust sucked in.
I was on a 240km ride. First day no Dusk at all. 90km. Second Day around 90km with maybe 30-40 km light dusk. 3 day. the rest km with maybe 20 km of light dusk.

Now i want to make sure everything is ok.
I removed throttle Body and cleaned that out.... Checked with a small Camera inside the Bore and Valve seats as much as i could.
I didnt feel any difference in Power or what so ever.

I checked Compression today, but not sure how much it should reach since the Decompression is on the Exhaust Valve side.
With the Decompressor i get 60psi reading.
Thought about to take the Rockerarm cover off and Block the Decompression Valve.

Any Suggestions what to do and /or how.
Did someone experience the same sort of thing and what did u do ?airbox left.jpgairboxinside.jpg

Thanks
 
Just removed the Cover and blocked the Decompression with a little piece of a rag. Connected the Jumper Battery and did it again. But the Starter wont even crank more then 60 psi.
So i checked valve clearance ...Intake at .09" and the Exhaust is at 0.10"


Any need to get them adjusted ... Bike got about 1450 Km on or around 880miles.
 
If it was me, I'd clean up what I could and ride it.

Don't try to start a bike like this with the e-starter or kicker with the decomp disabled, really bad things can happen.
 
You definitely are not getting an accurate reading. 60 psi is most certainly bot going to go bang! What does the service manual say about compression checks?

Was there any evidence you have an issue by residue in the intake? I have had filters on much worse than that over the years with zero issues. I know that sinking stomach feeling when you see something like that on such a nice bike - been there! As long as the intake was not filled with junk, you probably did very little damage...

Like OldHuskyRider said - clean it up and ride.

60psi is about right for a high compression bike bike with an automatic decompression release, 60 psi will get it started.

60psi is what the bike can come up with.... more is not possible through the Decomp valve. It would come up with more but as soon u hit 60 psi, the starter will not turn over anymore.

Right, I understand - which doesn't tell you anything. Well, it tells you that it has 60 psi or greater - it runs so you sort of knew that.

Ride it...drama may unfold later, but I bet it does not.
