Next up, and "internal mod"; changing the oil jet for a larger one. Plus replacing the OEM clutch slave while at it
The original LC8 had no oil jet, or more correctly an oil jet with no hole! The Dakar racers were finding that in high heat and heavy clutch work the clutch was slipping/failing, and their solution was to put in an oiljet with a larger hole. I think some of the racers ended up running a 1mm jet, however for street use this has the side effect of making the clutch too sticky; resulting in a hard time finding neutral, or clunky low rev gear changes. KTM decided on a 0.3mm oil jet, and LC8 bikes since about 2005 had this. All SE's have a 0.3mm.
An "upgrade" is to go slightly larger - CJ Designs and Zen Overland sell a 0.5mm upgrade kithttp://www.zenoverland.com/ktm-990-adve ... -05mm.html
However I'm cheap, and after a bit of research found a Honda part that does the job with a 0.75mm jet. Slightly on the large size, but we shall see how it goes. I think that Zen Overland have recently put their price down - if I'd seen the above link I just would have bought theirs
The oil jet is meant to be cleaned as part of your service:
The Honda part:
I definitely notice the "side effects" of going with such a large size, but I'll see how it goes over time....
Two top tips:
1. For removing the jet it can be a little tricky. I have a thick screw driver bit which exactly wedges into the screw driver slot of the jet - meaning it just lifts out. The other methods is using a blast of compressed air, sucking on a bendy straw, or a hair clip.
2. A blocked jet is common, as muck accumulates around the jet. When you remove the jet for cleaning, replace the plug while the jet is removed and run the engine for a couple of mins to cycle the crud away. Do not ride the bike or use the clutch while doing this, just idle it. Don't forget to stick the cleaned jet make in!!
The OEM clutch slave is a bit of a weak point on the LC8. It's far too small to handle the large clutch of the bike, and KTM simply used the same clutch slave as they use on their smaller dirt bikes. My Adventure one failed in about 6,000 miles from new. Others have bikes with 30k + miles on them, it is just one of those things. But as I had the kit, I mounted it for peace of mind.
I used the Oberon slave, and billet mounting plate:http://www.adventure-spec.com/default/o ... re-se.htmlhttp://www.adventure-spec.com/default/o ... m-lc8.html
Simple bolt on, and bleed the system. I was horrified at the gunk in the master cylinder - the bike has 14k miles and it was watery brown gunk! You can see the finished article below, nice orange bling!
