    I have a 2008 610. I am curious if anyone has considered extending the clutch engagement arm? I will elaborate in a bit. Mine recently snapped inside the engine, which is a common failure point. I fell into the trap of over adjusting the cable because it was difficult to find neutral thinking that would solve the problem, and was unaware that was just one of this bike's quirks, should've read into it more. Live and learn. Anyways, I have a veryyy overpriced ($270 Canadian ) but better quality part on order from HTM racing in Italy, wont make that mistake again. $$$$$

    Here are my thoughts on modifying the arm though. It's no secret that these clutches are pretty heavy to pull by modern standards. I don't see any obvious reasons why one couldn't lengthen the arm that the cable attaches to on the engine end, thus giving more leverage and an easier pull. Could be done by simply bolting a longer steel piece to the existing arm. The increase in pull distance created by the extra arm length can be offset by an aftermarket, adjustable clutch lever, which I already have installed. Seems like a pretty simple solution, anyone tried this? Or have any reasons why this might be a bad idea?

    My understanding is that would make the pull a bit easier if you did that. I don't think it would make it any easier to find neutral. I've gotten used to blipping the throttle a bit while still rolling to a stop to find neutral easily.

    Extending the arm should work.

    Extending the arm should reduce the force needed to pull the clutch lever, however it would also increase its travel needed to disengage the clutch and I think that then the lever would hit the fingers holding the handlebar (I assume there is consensus about the fact that you are not suopposed to pull the lever with 4 fingers).
