I have added 2900kms to my KLE since I bought it a couple of months ago and am very pleased with it.
I have transfered from my 650 V-Strom, which is now for sale, a throttle lock, the type you flick a little black knob with your thumb and a top box I had made in 3mm Aluminium 550X 320X 340. I love both these items for their great function.
I mentioned elsewhere that I removed the small airbox snorkel. I fashioned a small awning in thin metal sheet over the top to help keep out water off the exposed rectangular hole but as I half expected, the bike ran very sick. I quickly replaced the snorkel for alteration at a future date.
The other change I made was to release the tiny amount of air in each fork and gave each fork 4 pumps with a bicycle hand pump. As I said on the V-Strom forum NIVANA! Well very good anyway. What a quantum change. The forks are extremely comfortable, very compliant and track well, holding a line when punting a little harder than norm. Perhaps the spring rate could be increased but only 5kg or so.
And that's the only change so far BUT I expect to have a new KTM exe exhaust in the post this week!!! One cat down two to go. I was hopeful Barrett Exhausts could make up new equal headers for me but they are busy and said to phone them again in a couple of months.
Staintune on their site, claim a gain of 2HP for the exhaust and a loss of 4.1 kg. Not huge but handy.
I plan on some carby mods, not just jetting but handy, fairly easy changes to the internals for better air flo. I'm planning to also sell a Z650 I have restored to very good but not concourse condition and will keep just one bike. It may be the KLE in which case I'll be looking for at least 55hp but usuable mid range power. Not sure which way to go but possibly a Triumph 800 XC but don't say a word to my fair lady.
