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 The previous version was outdated and no longer supported.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

:excuseme: Had my temp sensor replaced a few weeks ago.

Went for a ride tonight. Bike was hard to start then 15 min later the neutral light starts flashing again. Dealer told me before it would not hurt the bike to keep riding it last time. about 4o KM later the bike starts surging like mad. I stopped to look at it and find the bike running hot enough for my new Klim jacket to melt on the rear of the exhaust. < Nice > I managed to limp home with the revs jumping up and down over a thousand RPM. Almost impossible to start out from a stop.

Bike is now loaded in the back of my truck for a trip to the dealer again. Anyone have any ideas ? I have stock exhaust but a JD Box and the air box opened up. Just over 5,500 KM on the bike

Forward two days...

Looks like mine was not the temp sensor this time. Ibeat shows a repeated error of " low manifold pressure" The bike was acting up a week ago but cleared up. It seems that there is water in a connection between the sensor and the throttle body. Dealer cleaned out water and plug but could not get connection 100%. I had to leave the bike and he is going to work on the throttle body connections.
 
I think this is the same problem I am having after washing the bike. Did you ever get it solved and how


Ran Ibeat and the error code indicated manifold pressure sensor.
 
Water can get in the tps connector and short it.

Have a read of this thread http://www.cafehusky.com/threads/630-erratic-running.31303/
Prior to that thread it had already had the tps/throttlebody replaced when it threw the low map code.Which they found water in and a busted seal.Not a very good design.

Ok i can add a tps and maf sensor to the list.Don't know how they failed.The bike backfired and started shuddering and threw a code. Complete throttle body has to be replaced as parts aren't available individually .None in this country have to wait for them to come from the factory.Another one for warranty.Must be getting close to having this thing sorted.

Ok.. at this point I've solved my problem. I swapped out the fuel pump, battery, coil, plug, and a few other items from my girlfriends SM630 and none of them resolved the issue.

The MAQS connector was removed and I found water in it.

I was able to solve the problem by running a hair dryer on both the female and male sides of the connector for a period of time and then applying dialectic grease to the connection pins and the engine finally came to life.

I was near swapping the throttle bodies but this solution fixed my problem.

Does she know she owns a PARTS bike? :lol:

yes.. she told me if the parts swap didn't help diagnose the issue with mine that I could always just ride her SM630 if I want.... so it was a win/win situation.


here is my parts bike and my wonderful girlfriend! :D
