KTM 950 Fuel Hoses

I may be having a blonde moment. I accidentally poured Diesel into my bike at the gas station yesterday, so drained what I could out and the filled it with petrol. She ran for a few blocks and then suddenly not happy anymore. I think largely because the bike was on its sidestand, and there will be a little pool of diesel in that corner that was the first to be sucked into the fuel hoses.

I also noticed my fuel lines are showing their age/heat cycles, but for the life of me I cant find the diameter of the hoses to buy. I think there may be two sizes, between the tanks, and then to the carbs.

Does anyone know the sizes of the fuel lines on an 08 KTM 950 SM-R (likely same as ADV).

Killboy,
there are two sizes: INSIDE diameters of 6.5mm and 8.0mm.

Just buy a metre of each (more than enough, but be sure to buy fuel hose) and replace like with like, preferably using reusable fuel-hose clips along the way. Why not add a filter in there too whilst you're at it.

Mine were in poor shape too (SM 2006) and I replaced them last year.

Cheers... Paul

On my '06 950 Adv, the fuel hose running from the pump to the carb is 7.5 mm ID. It is some German brand as used on Porsche.

Noticed that the only remaining factory section of fuel line on my KTM was cracked last week. I replaced all of them with Tygon fuel line. Motion Pro makes it and your dealer should sell it by the foot. It's really good stuff and does not fall apart like the crap they sell at the auto part store.
I use 1/4 inch for everything. It's a bit too big for the take cross over, but I use zip ties to crimp it down.

Brand is likely 'Cohline' but it's basically the same as standard black fuel line you'll find at NAPA except the US stuff is imperial sizing first and close metric approx second.

Either way, if you're going to the hassle of replacing the line I'd replace with Motion Pro plasticized hose. http://www.motionpro.com/motorcycle/...ium_fuel_line/ It's not cheap but it won't harden and it's way more flexible so it's a lot easier to fit onto the main fuel petcock.

6.5mm is 1/4" 8mm is 5/16"

To me, Tygon is slightly different but it'll work just fine. You can get it from NAPA. Usually one location in town (main warehouse) will sell it by the foot. I always get the translucent yellow which I use for carb drain hoses. It's probably available in clear, I've never seen black. For the narrower widths my recollection is that it was closer to $1/ft. Could end up being a lot cheaper than the Motion Pro stuff which is like $6/ft.

Forgot to thank all you guys for the help. I ordered a mix of 6mm and 8mm and re-did all the lines, except up to the carb, as that looked brand new and was fine.

Got her running again, and was going very well, but occasionally there is now a misfire. Ever so slight, and do not think it is diesel anymore, but more like air in the system or something - its too short and quick IMHO. Maybe a long burn is what she needs.

Spark plugs are cheap...I'd slap a new set in her.

Yeah, I guess so. I was thinking about doing the Valve Clearances too, so may as well go big. :(

So this has spiraled a little.

I stripped the entire bike down to find two things.
1. The plug removal socket I bought specifically because I knew standard ones dont fit down the tube was too small for the actual plug.
2. You gotta be brave to yank the carb boot off the intake cylinders. I'm not that brave.

So the misfire is still there. I know nothing about carb, so I think I should send it to a pro.

On idle its fine. On full throttle its fine. But occasionally if you sit at like 1/8 throttle just keeping speed constant, it hiccups, dies, backfires, jerks, etc. In these icy conditions it makes cornering fun. Its just dangerous.

I wonder if it could be electrical?

Carbs are simple. Buy a can of carb cleaner and we'll walk you through it.
Oh, and the carb boots. They tend to stick with a couple heat cycles. Just work them off. Even I couldn't break them.

They are breakable. I ripped one of mine removing a stubborn carb.

As far as the rest of it...could be carb icing...?

Ripped??? What did you use a crow bar?

I've only had them off once...so far. I made sure the clamp screws were backed off almost the whole way. I twisted them on the intakes to make sure they didn't stick, and worked them off with my fingers.

Chuck makes a good point: do you have the carb de-icers installed. My `04 does not and living in the northern U.S. I'm going to make sure they go on before spring.

Carb de-icers are there and look fine. Cables are good, etc. Dont know if they actually working however.
