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 The previous version was outdated and no longer supported.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

SMR 4t 2012, Bogging on acceleration, loose check valve in float bowl.

Hi, wonder if someone could help. SMR 125 4t started to bog on acceleration, so decided to clean the Carb (Kelhin CVK 39 CBR). Took of float bowl to find a small check valve and tiny spring and ball bearing loose in the bottom of it. Found where it went, is part of the acceleration pump system and goes in the bottom of the float bowl. The problem i'm having is I don't know which way round the spring and ball bearing goes in. There is no info on diagrams of this Carb showing these check valves.
 
Most on this site are not familiar with SMR125's (at least that would be my guess, though someone may be able to help).

I am familiar with FCR Keihin carbs, then in the many places in the world they went to EFI.

If it were me I would seek a parts manual for that bike, and I've no idea where you would find that.

Could anyone help?
 
Got it sorted thank's. The ball bearing goes into the hole then spring inside valve screw then screw in position. Put a tiny amount of blue thread lock on valve threads to stop it occuring in future.
It was bogging due to fuel getting through check valve. Now only issue is racing on idle between 1400rpm and 1800rpm.
