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.

I think that this would make sense.

KTM Dealer for Parts

I'm thinking about buying and carrying a spare injector for my 2010 690, is there a reliable dealer that sells & supplies KTM parts over the internet at a reasonable price? I would be shipping to a US address.

I just bought a windscreen for my 690R from Surdykey Yamaha. Only $51 (20% off) AND free shipping!
I found out about them from another inmate posting here.

http://www.surdykeyamaha.com/

Looks like $131 from them for the injector.

Hey guys
Thinking of dumping my 06 drz400s for a 690. What do you guys think honestly? Is this 690 worth the big price tag? What are its advantages? Disadvantages? Must do mods? Thanks for any help in advance

Had a big box from ktmtwins sitting in the garage when I got home from work today! Evo1 airbox lid, touratech seat and crashbars, oil filters, 12v outlet and orange valve stem caps :) Adding the evo1 airbox lid definitely makes it a little noisier but man does that beast fly now.I am afraid to put it on the #2 map setting now... Already had the evo1 map and full akro exhaust. Disappointed the crashbars dont fit with the flatlands racing skidplate :( I asked if I had to use the touratech skidplate and they said no but I should have asked if it would work with any skidplate other than stock!
