In all my previus 4t thumpers I've always makes a cage to avoid this eventuality, it's an old racing habit

The much slimmer tank profiles allow for a similar slimmer fairing design,using our own tried and tested cockpit support from the previous kit,which has been tested extensively off-road over the last 3 years.
We have also sourced a new 450RR style twin headlight,with a really neat "halo" effect parking light around the high beam light.This fits into a new screen,but still retaining the "rally style lip" on the top of the screen,to help against buffering.
We expect production of these kits by mid-september,and they have been designed to fit all KTM 690 Enduro,from 2008-2012,and we will also be able to supply existing Rally-Raid kitted customers with an "upgrade" kit,if required.This will consist of the new tanks,the extra lower mount and new fairing sides,screen and headlight,to fit their bikes.
The new headlight & screen combination will also be available to LC8 owners,as an alternative to the standard KTM headlight & screen

Beautiful! You guys outdid yourselves on the new tanks! Looks like I need to find a home for my old tanks

Just read what I have posted few days ago in this thread. It has nothing to do with backfire. Your airbox pulls the throttle body out. Don't think for now. Just do what I say. Something at the front of your airbox pushes it toward the rear end. either the coolant air breather, or a cable cluster that was inappropriately routed.

thanks for the suggestion :) but it's not my case, i've heard the explosion from the air box (and the engine stalled), is a backfire

[QUOTE=Night Crawler;18908830]My bike has never even missed a beat, and always starts on first crank until this weekend. I went to start it mid-way through a ride when the bike was hot and it just cranked over continuously but would not start until I cranked the throttle wide open and bam it fired right up. It ran perfectly until I got back and would not start again. I have been able to start it the same way since, but it is very difficult. After it starts, its seems to run fine. I can hear pump coming on normally, and I changed the spark plug and cleaned the air filter. I have found no loose connections, only what looks to be a missing ground on the left side of the frame right below the air box bushing mount, but I can not find a wire that would go there. Is this an extra grounding point or was something going there that I cant find? Thank you for any help.

I am pretty sure that is just another grounding point. Both sides have one if I remember right
Had this issue come up again. This time threw the error code for the rollover sensor, so I tipped the bike over on its side and it started right up. Is there a way to eliminate this sensor instead of just replacing it? I am a big fan of getting rid of possible sources of failure.

Today I fired it again and it is still smoking. I thought it might have too much oil so I drained it and checked the screens. I don't have new filters but these probably have less than 1500 miles on them. Still smoking a lot. I drained some of the oil out, still smoking. I pulled the air filter and there doesn't seem to be any oil in the air box.

I don't know why it would just start doing this. It has smoked before but I think it was over-filled and would stop pretty quickly.

So what are my possibilites? Sucking oil into the top end? Burned valve? Broken ring?

I finally got into the bike this weekend. The head is fine, the cylinder is fine, the Nikasil is beatuful, The piston is sloppy loose and the rings have about 1/8" gap. I have no ideas. Fewer than 7000 miles.

How do I know if I have Cylinder size 1 or Cylinder size 2? I have measured it with three sets of calipers and it is ever so slightly under the minimum for both but would come closest to size 1.

The cylinder says 102/10P on the side for what it's worth.

Which air filter were you using? also check the PCV hoses where they attach on the RH side of the frame next to the air box.. One of mine came loose and was venting to the atmosphere.. I caught it before it sucked any dirt into the engine.

Mine is smelly and drinks oil like no tomorro, no smoke tho.

Last 1000 km ~ 5 dl 10/60 :(

Stock paper with grease around the edges. I have seen very light traces of dust in the box before (which I heard was common) but nothiing I would think would accelerate wear like this. There are no traces of abrasives in the throttle body, head or connections.

Interesting. I'd be more interested in solving the backfire issue than harnessing the TB. I have not had a single backfire on my bike in 8000 miles of hard riding...at least nothing that popped the throttle body off.

It appears that the 2012 models (at least some) have a warm start issue. Mine acts like it isn't going to start if not given a slight amount of throttle....the wrong amount results in a serious backfire on occasion which usually blows the throttle body nearly off the intake stub. My 2008 model has never started any differently hot or cold...no throttle.. maybe 1 or 2 very short bumps on the start button and it cranks right up. The 2012 will eventually start when warm with no throttle, but it takes several long (3-5 second) cranks with the starter. As usual, KTM NA has no clue according to my dealer and actually blamed it on my FMF slip-on in spite of the fact that they were told it had the same issue with the stock muffler.

Dust in the airbox is not good. After correcting the wear issue, be sure to change to a different air filter. Flush the crankcase well, because that dirt is still in the bottom end.

Yes mine is like that too feels like it needs one of those hotstart levers like my crf 450x has
