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 The previous version was outdated and no longer supported.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

Small fuel leak from?

AA Class
I have a very small fuel leak coming from some where under the fuel tank on my 2013 TC R 250. Only reason I even noticed it was because it left a small puddle on the floor and on the top of the engine case. Also you can smell fuel after a ride when bike was in the van. So far it has not effected the performance. Anyone else ever had this problem? Thanks in advance for the help.
 
Hi Ricky-

I have a TE and I think our tanks are different; but I caught (by luck) a hole being worn in my tank. The location was the lower left side front center (inside) corner, which was being rubbed by a radiator hose clamp.

Your tank and the hose routing on your TC should be different than my '14 TE- but take the tank off for a look anyhow. [and I am assuming here that we are not talking about a high pressure leak. Just for grins, first try pushing both ends of the fuel line in- if you hear a "click", your problems may be over. Someone earlier reported a fuel line quick-disconnect not fully engaged from the factory] Maybe blow into your vent hose to increase the pressure to help you find it. Check the screws for the fuel pump plate (no petcocks, right?) but watch the torque.

Small holes are easily repaired (if the tank is HDPE- and I'm not real sure it is) by melting filler material into the hole with a small soldering iron (not gun). Glues do not work well on polyethylene. Safety caveats: Empty, fume-free tank; fire extinguisher yada-yada.

The way I caught my wear problem was that I had put heat-reflecting tape around the areas of the tank closest to the header pipe and engine head radiation (SOP for me & gas tanks). The next time I took the tank off, I happened to notice a small spot that was missing the tape. This is just a couple of inches forward of the TE's other wear problem of the screw hitting the water pump outlet hose.

I've never owned a vehicle with so many minor rub problems: tight clearances and a stiff wiring harness with no slack is the culprit I'm guessing. Really gotta keep an eye open for issues like this:banghead: - but I love the bike though.

good luck.

On my carbureted 07 TE450, the petcock seeps a drop or two of fuel when moving the valve. Not anywhere near close enough to puddle anywhere.
 
Also check the petcock hose as even a Sharkbite clamp can be stretched and begin to leak if it is compromised. I got my bike back from a dealer and when they mounting the tank, routed hose in such a way it was completely stretched over the spark plug and wires pulling the clamp against the barb. This was enough force to stretch open the Sharkbite and cause a leak :banghead:

Fixed with a Zip Tie and last time I have been back there :rolleyes:
 
Ricky. Yes. I have two of these bikes. One started leaking and the other looks like it may start.
Problem I found was with the fuel tank. Where the fuel pump assembly mounts to the fuel tank there is an O-Ring. This creates the seal between the pump assembly and the tank. On both bikes, unfortunately, I found that the fuel tank itself was not molded very well. At the sealing surface where the O-ring seals against, the sealing surface of the tank, it is warped. This caused a huge gap that the O-ring could not deal with.
What I did, I removed the tank and pump assembly. I very carefully ground down the high points of the tank and the nut inserts in the tank. This made the sealing surface now level enough for the O-ring to do its job. As an added precaution, I spread a small bead of Yamabond sealant around the mating surface.
No more leaks. This takes patients and a steady hand. Do not take off too much.
Hope this may help you.
