Tecate petcock leak

[BELGIUM KXT250]

Hi,

I have a (minor) leak at the fuel petcock of my tecate. Even if it's not too bad until now I know that it will be a problem in the future so I would like to fix it.

Unfortunatly all the schematics for this bike online have the complete unit only at approx. 45 dollars. I just need one gasket I think the one at the tap lever because the leak is located there. The schematic for the KLT-110 is more detailed and the fuel tap of KLT-110 looks really the same than the kxt but the partnumbers are different...so it shouldn't be exactly the same.

In case I should have to replace the 2 gaskets I found a KLT-110 fuel tank gasket and I am 99% sure it should match the one in the tank of the kxt. See the pic below.

So What do you think ? and for the other o ring (fuel tap lever) I really don't know where I cand find that ?

Nice job it looks great with the red tank and red tap lever

i used the rubber o-ring type gasket off a kx125 petcock on mine. was the same exact thing. worked perfectly.

Thanks for the information Scooterroo. Always good to know we can use the o-ring of a kx125

Just get a new petcock off a different machine... You might be surprised how many choices you have... Most 2-stroke machines that have a reserve supply and a mikuni carb will likely bolt up the same...

Well having read that I am wondering if the previous owner of my tecate hasn't already replaced the stock petcock with another one. Altough on the schematcis it looks like a stock one but the Mark of my petcock is MBK and correct me if I am wrong but MBK belongs to Yamaha isn't ?? why should kawa have used a MBK petcock ????

Although I haven't done it myself. I have heard that a banshee petcock bolts right up. Its a much better built unit. The oem tecate one is not a very good design.

A blaster petcock bolts right up. Stronger design too than the tecate.

[BELGIUM KXT250]

I agree for the blaster petcock it looks very similar to the tecate. It should fit.
The banshee too looks very similar. See the pic attached it's a petcock of a 1987 banshee.
I may try to replace my tecate petcock with the banshee one. I will let you know if it's work or not.

[RID3R]

have you done this or just read/heard it somewhere?

I have done it. I will get a few pics up later of it on my tank. From the pic of the banshee that should work also, looks just like.

Blaster petcock

i have tried 3-4 different ones. kx250, something from a yamaha and a couple of others. they all bolted up but they all leaked..

[RID3R]

Where was all the leaks at? If you have a leak from the petcock to the tank itself, its best to use two of the rubber seals... Ones not good enough over time...

[kxt250r]

all leaked from tank to petcock. so you got a blaster petcock and just added an extra seal then yeah?

[RID3R]

Yes, mine even leaked from the tank too. I used the old tecate seal and the seal with the blaster petcock when I got that. Unless you get a new petcock with seal etc. It may not leak but either way using two seals is best.
