I literally just extended mine yesterday, along with a full length lever, deburred the perch, and lubed the cable. I think the pull is no joke, about half...

I'm glad to see that Mr. Fredette is still at it. This mod really does help.

Ridea200,
What arm length did you produce?

It came out to 33mm measured from center of welded area to center of rivet. 8mm extension with a slight dogleg as suggested in another post.

Thank you. Similar to Fredette fabrication.

So Jeff's appear to be approximately a 5.5mm extension versus the stock KDX clutch release arms. This sounds like an excellent length to me, & I believe around 8 mm is the maximum without creating an odd angle on the cable.

The longer the arm is on the engine side, the more lever pull you will need to get the same disengagement effect at the clutch basket. Too much extension on the modified arm would cause a very short clutch release travel distance for a very long clutch lever pull required.

This past season I finally started to get more comfortable clutching over difficult obstacles such as tall logs and large rock shelf steps, and in the quest to achieve that, I found that it was much much easier to have my clutch lever reach resting position dialed back considerably closer to the handlebar to where the release point causes unfamiliar people jumping on the bike to stall it almost immediately, because disengaging the clutch for me now with this adjustment means pulling the lever back nearly to the handgrip to have it completely disengaged. This really gives me a lot better control over it without feeling like I'm having to lose control over piloting my bike through the handlebars due to having my dominant first few fingers not on the bars but on the clutch lever feathering it.

Although I'm starting to feel the effects of middle age a lot more now with a lot of chronic wear and tear type ailments at 47 years young, I was not really looking for a lighter clutch feel at present, my only reason for doing this mod is to run 10% firmer aftermarket clutch springs to get more grab for a modified engine ridden aggressively. The drive when releasing the clutch lever is considerably improved at high RPM according to MoonStomper's accounts through his personal experiences.

At least on my bike, the cable came out at an angle in stock form. It's pretty well centered now.
I actually haven't ridden it yet, as I'm waiting on a throttle cable.
Like Chuck78, my buddy and I have been hitting some pretty gnarly areas around here, so for me a lighter pull will be welcome. And if the engagement point is close to the bar like Chuck said, cool, I actually prefer that...

Can tell you about aging progression from my personal experience of hitting the ground.

Age 50: Fell and no longer bounced. That's when I knew I'd aged.

Age 67: Fall, even yesterday. Now it's a just big thud! Riaingfrom ground is noticeably slow and falls usually hurt a little bit.
