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 The previous version was outdated and no longer supported.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

125-200cc Exaust Leak - Affecting Jetting

Hey everyone

My bike's developed a leak where the exhaust meets the motor, and there's spooge leaking all over.

Question: can such a leak cause the motor to run rich?

The bike seems to be running richer all of a sudden and it coincided with the leak so I'm trying to figure out if they are related?
 
when the exhaust is leaking the total amount of air pushed through the motor would probably less at the range where the pipe is tuned for and that's probably also the rev range where you like to ride the motor in

if less air comes in the motor the percentage of fuel in the mix will increase and would result in running richer

Get some new o-rings for the header. Have you looked at the plug, changed mixture, changed pre mix oil? Vent lines to carb not plugged are they?

Do all that stuff and see if it goes away.
 
Yeah, pull the pipe and see wtf is going on. While the pipe is off shine a light in there and have a look at your piston and rings.
:cheers:
 
Thanks for the replies, everyone.

Will try re-sealing the pipe. These bikes (2012 WR 125) run a single metal o ring, right?
 
No mate. They run a normal type o'ring in the groove on the pipe and a steel washer where the pipe seats against the barrel (at the end of the pipe).
 
My 150 was messy at the exhaust manifold. When I did the 165 I found no steel washer, so installed a new one with a few blobs of hi-temp silicone to hold it in place. New o-ring too, no more mess so must be sealed up well.
