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 The previous version was outdated and no longer supported.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

Cruncy sounding fuel pump

I noticed that the fuel pump on my TE510 doesn't sound smooth like it used to. It doesn't go, "zzzzzzzzzzz" any more. It sounds a little crunchy or rough. Sort of like it's sucking air. Doesn't sound right to me. It's working fine, but my confidence in it's ability to continue working is low.

Has anybody else had this symptom? Who is selling the after-market (just the pump) replacement?

Pull your fuel pump assembly. Cut the side out of a 5 quart oil jug, a big enough opening to lower the assembly down into it. Hook up some wires to yuor battery with alligator clips. Run the fuel pump in a mixture of 1/2 gal gas and a bottle of fuel injector cleaner. This procedure almost rescued my varnished up pump some months ago. Yours may be cleanable. Having it out and running will allow you to hear more clearly what is happening. I did mine like this in order to keep from burning a concentrated cleaner in my engine just to clean the pump. I do put a few ounces of FI cleaner or Marvel mystery oil in my tank every so often, to keep the pump maintained.

I'd be ordering the replacement pump as a spare anyway. It can be replaced trailside.
 
OK, I'll give that a shot. Thanks for the tip.

BTW, I've used Marvel Mystery Oil for decades in everything from Lawn-mowers to Lycoming aircraft engines. It's a great product.
 
You will notice this when you pull the pump, but sometimes the tie wrap securing the pump holding clips comes loose allowing the pump to slip up and suck air or run out of gas. I guess if your pump sounds different with a full tank, that would eliminate that possibility. But it would be a good idea to double up on the tie wraps to keep things in place while you are right there.
When I checked mine the tie wrap had slipped up, and the clips were barely holding the pump. One good jolt and it could have slipped out.

I've done the pump mod already. Mine is held in with a SS hose clamp, safety-wire and multiple tie-wraps. It's not going anywhere that the rest of the bike doesn't.
