I believe so. When I removed the left gas cap the fuel did not stop boiling until 5 minutes had passed.

Hey guys!
Read through most of the posts and wanted to thank you all for adding your mods and thoughts.
That being said I cant help being frustrated that i cant find a summary of must do to the bike and proper tuning of the engine.
Electrical connections break or were not done correctly from the factory, the fuel tank may come lose, the throttle may fall apart, the bike might just start stalling on its own, the fuel pump seems to stop working after a certain time, etc.
Some people put on pipes and tune, others dont. Some mod the airbox, tune and other dont. Then there is a huge amount of tuning codes available. Some people just put in a new ECU.
If someone knows where I can get a full one page summary of the info that would be very helpful.
This is either the most complicate motorcycle on the planet or Im terrible with Google.

Thanks guys.

Check out the http://ktm690.info hall of wisdom. It's not really a how to setup a new bike but it's a compilation of common breaks and fixes or mods.

I don't know of a one-page summary, but this will get you most of the way there with a few pages of reading.

BTW, it is perfectly acceptable to ride the bike 100%-bone-stock and to expect to have a wonderful time. It is not, as some of might like to imply, a time-bomb ready to drop dead in the darkest corner of the earth. So if you just plan on driving around town you can pretty much ignore all of the mods with no greater risk of mechanical issue than any other modern bike.

If you find someone that has spent a ton of time with a dyno and trying different air box mods and pipes, please let me know.

In your earlier post you mentioned running a non stock map...
Stick your fingers between the pipe & the tank after it's warmed up
If it's hot enough to be uncomfortable, you have map problems...

Is it possible that what you think is boiling fuel is actually fuel gravity flowing into the tank?

Not quite sure what you mean by that, but it was definitely boiling. The way their fuel taps are setup wouldn't allow for bubbling unless it was boiling. These were not small bubbles either in the left tank it was somewhat violent churning.

My pipe was way to hot to do that even on the stock map. My map is the KTM factory evo-1 airbox map so I doubt it would make the bike run hotter than normal. The heat feels the same on the left side if not a bit more concentrated (which I would expect) since the tanks were installed.

He's was asking if there was an imbalance in the volume of fuel in one tank compared to the other and if the "boiling" was simply gas flowing from the tank with more fuel into the tank with less.

Fuel transfer between the Evo tanks is really slow, so its unlikely. In my opinion, there will be signs of heat damage to the lower left tank if the exhaust set-up was the cause. I wrapped heat bandage around the heater and stuck aluminium heat tape to the tank, but I think I was over-cautious.

I put exhaust tape on my left side tank, but it came unstuck after 1 or 2 days' riding....
based on the amount of heat coming off my 2012 with stock map...I'd say something is wrong if you're getting enough heat to boil the fuel.
I suppose you could get a cheap industrial thermometer and see exactly what temps you're dealing with..
Rally Raid posted on this thread (I think) that they were having trouble with the Akro header pipe over-heating the left tank, but no info on the stock header pipe

When I removed the left tank cap I could see the gas level was low and I could see it boiling when I started to take the right cap off gas was pouring out so I retightened the cap, pulled over and let it cool down for five minutes before continuing home. Later in the evening I looked at the tanks again and the left and right tanks had equal amounts of fuel. I had this happen on my 950 adventure when I installed a second radiator fan on the right side.

I'm running the stock header pipe with an FMF Q4 slip o with an EVO-1 airbox and FI map. 2012 690 Enduro at 1830m elevation (6000ft).

I am curious to see if I'll have similar problems on trails in the mountains where my 950 had issues with heat and boiling the gas.



As far as vibrations coming through the tanks it is very annoying, no one else has experienced this? they are not minor; and I'm running a TKC-80 up front and a Metzler Sahara 3 on the back, both are balanced. The stock side panels did not vibrate from what I could tell.
Like you, I had fuel boiling issues when I installed a second fan on my 990. I tried reflective insulating tape on the right tank where the fan output was hitting the tank. The final solution was to fab a deflector for the right fan similar to the deflector used on the left side tank. I'm guessing that the 690 fan needs a deflector so that its output does not go directly on the left side Evo tank. Before I installed the deflector on my right 990 fan, the right tank would get so hot you could not touch it and fuel would boil if it was high enough in the tank to reach the hot portion of the tank.

Yeah, after thinking about it for a bit that might be the case with the 690. I'm going to check it out a bit, though as long as I'm moving it's not a problem; it's only in heavy stop and go traffic. I will need to find a solution anyway since the trails here have lots of slow 5-15mph climbing and generally are not gentle on bikes as far as heat goes.

I also fabbed a deflector for the 950's right side fan and that solved problems on that bike.

I ran a 150/90/18 Terraflex on the back for about 1500 miles. It would contact the underside of the tank with a decent hit, but I think that with a more typical 150/70/18 you would have less clearance issues. As far as fitment on the 2.5" wide rim, it fit just fine but is probably a bit more "crowned" than most people prefer.

Right, the boiling only occurs when the fan is on.
