It will most likely fit the bike, the problem is that there is an enormous hole in the bottom of the tank that the fuel pump bolts into. The carbed bikes obviously have just the petcock on the side of the tank.

In theory, the hole could be filled with a block off plate, and then the petcock mounted in the lowest possible spot. I've read about another bike where there were no aftermarket tanks for carbed bikes, but later EFI models had upgrade options, it may have been a KTM model. Someone did just that, blocked off the pump hole, mounted the petcock. I think that they eventually got the petcock working just fine, but had problems with the fuel pump block off leaking after 2-3 weeks on each attempt. Not sure that they ever got it worked out.

Some plastics are tricky to bond. Seems like a few calls to some plastics and/or adhesive tech guys would help figure out the best method and materials to use.

Perhaps the tank manufacturer could supply some tanks without the pump hole drilled out.

Yeah, it definitely seems feasible, I just know that the one guy I read about doing this had major problems.

I think that the holes are part of the mold, but if they are cut after the fact, seems like it'd be a very easy fix!

4 colors available, 4.75 gallons, $238. Definitely worth looking into if you have a 2013 model.

Honestly, knowing that the carbed version of the 250 was only sold in the US from 2008-2012, I doubt that a carbed upgraded tank will ever come to market here. MAYBE overseas, since they were available a few years before here, but most places converted to EFI before we did as well.
NICE!!!!! But.... i have a feeling that the hole for the fuel pump is probably under a spot where the petcock wont fit... it always turns out that way.

Almost 5 gallons tho, that is awesome, good find top_dog

It is dead smack in the middle of the tank. It's also much higher than the "wings", so you'd want to mount the petcock elsewhere anyway.

Wanna ride your 250cc for a 600 km rally?

Hey guys!

Put your money where your mouth is with all this minimalist touring talk! Show up at CMG Online's Dawn til Dusk Rally for 250cc or less motorcycles, running Sept. 15 out of Moncton, New Brunswick, Canada! It's not that far from a lot of major eastern U.S. centres!

Read about it here!

Read about last year's rally here!

It'll be 600 kms on 250cc or less motorcycles, along N.B.'s Fundy coast, and up and down the St. John River and Kennebecasis River. There'll be cable ferries and covered bridges! Act now! But wait, there's more! Etc, etc!

No really, come on and ride it. I'll post more details when I have them, but we already pre-rode most of the route ...

I depends on the tank material, but if you can get the "patch" made of the same material, you can either heat or sonically weld it together. Both are leak proof. PE, HDPE or XLPE, are 2 common types of plastic for fuel tanks. The HDPE for sure is heat and sonically weldable. The XLPE is more difficult, but can be sonically welded. I do not know about heat welding XLPE.

Could also ask DirtySanchez over in the Loctite thread. I have the same sort of problem with a BajaDesign rear tank for my KTM. Really poor design (or lack of design) for the hose fitting. I am thinking of removing their stock fitting and possibly putting a Delrin plate over the hole bonding it to the tank and then installing a petcock from Clarke with an o-ring seal.

DuPont Multi is (was actually) dry, teflon lube, so doesn't fling, and doesn't attract dirt.

WD-40, or mild solvent like kero or Varsol clean very well. The concern with WD-40 aerosol is its penetrating qualities, displacing grease. Someone above mentioned using bulk WD-40 (liquid) and a rag. I'd feel comfortable with that.

The Webbikeworld article I linked to presented with evidence from an engineer that WD-40 can be harmful. http://www.webbikeworld.com/r3/motor...chain-cleaner/ It was compelling enough that a longtime motorcycle scribe and WD-40 fan stopped using it.

I only know what I read, and what I practice. No empirical studies out there that I know of. My chain life is very good. Sounds like yours is too.

Maybe we should start a motor oil thread
I like the BelRay chain lube and it doesn't seem to attract much dirt.

The other variables to chain wear which have been left out of this discussion have been sprocket materials and sprocket sizes vs chain length. There is a discussion of the latter (I think) over at the GearingCommander website.

Dissimilar materials are a problem to bond together. It is better to use the same material or same material with the same base components. Delrin may be a candidate for heat welding though.

"Sonic welding" ? That's a new one for me. I'll have to google for the wiki on that.

Wish granted! It works well on amorphous plastics and non-ferrous metals. It will also work on crystalline plastics, just uses more energy.

Some interesting information here:

Geez, that really makes sense! No wonder I never thought of it.

Thanks...

They said they didn't. But walked over a few minutes later with a can of Off bug spray as we were getting ready to pull the spark plug out.

I told him "No thanks, the bugs aren't bad"

He then told me to use it as starting fluid. And says it works better on a swamped motor because it contains some sort of oil in it. And it replaces the oil in the cylinder I had just "washed" out.

Worked great!!

He then told me, the Deep Woods Off (needs to be aerosol) seems to work the best.

I've used this MANY times. And always carry a can..... Think multi-use when packing.
