690 E R radiator overflow, pivot pegz, rim locks
Posted 18 December 2011 - 08:40 AM
After a long ride I noticed that the radiator overflow connection to the coolant tank leaks, it appears to be just a simple hose pushed into a socket with on o-ring, and prone to leaking. I don't recall anyone commenting on this, I had to hold it down with some electrical tape until I find a better solution.
I fitted a pair of pivot pegz, made in Tasmania (Australia) in a small town close to where I lived long long ago, and after a couple of rides where they felt a little strange, I am now convinced and can feel myself float at varying foot angles as I accelerate or decelerate or go into steep sections. They are larger and provide more grip than stock. Highly recommended.
After sliding around too many trails with the conti TKC 80, I had the pirelli MT 21 fitted front and rear, and swapped the standard inner tubes with UHD tubes, and a rim lock at front and rear. The shop did not balance the wheels, the bike was almost unridable due to heavy vibrations (especially when the 2 rim locks aligned themselves), so I got the wheel balanced... it looks terrible, but no vibrations, and although the MT 21 whine a little at highway speeds, in the dirt the difference is incredible and I can now comfortably go where the TKC 80 gave me much trouble. I am looking for balancing weights that fit on the spokes, but I have not found any retailer that sells those yet. Another solution is to balance the wheel with a 2nd rim lock, but the rim has just 1 hole as standard, the other would be custom...

I found a new problem: the screw retainer at the bottom of the radiator for the side panels, twists sideways and the sharp edge on it eventually makes a small hole in the radiator. I discovered this too late, when my right boot was wet with coolant after a ride. Bad design is my conclusion, I rounded the edges of both left and right retainers and reinstalled them, after putting some epoxy over the hole to stop the leak. I have not read about this problem anywhere yet.

I also include the images for the previous post, showing the rounded screw retainer, and my patched radiator. I recommend anyone with a KTM 690 should check to see that this screw retainer is not slowly punching a hole in their radiator. I reckon this should be a warranty issue, or even a recall of all affected bikes by KTM, but I have not heard of any recall to fix issues (except the handlebar supports which was fixed for 2011).
