Hey, first and foremost, thx so much for getting back to me so promptly, clarifying what you have, and including the extra couple photos! And, secondly, let me apologize for not doing the same.
So, I may be interested in what you have to offer. However, here is my issue (somewhat):
I did recently acquire a full blown "core exp 2.0" new and unused kit all of which is not yet installed. I understand that Rekluse may have a new EXP4.0 kit, just not certain for the 2010 FE450(?). I have yet to contact them about that and the noise issue I have with 2.0v. I have ridden the same bike with a 2.0 and 3.0 version and definitely can hear chatter with the 2.0v (mostly upon initial clutch engagement from dead start), and on occasion, can feel a difference with clutch engagement and slipping- that being better with the 3.0v.
Regardless, I do enjoy the benefits of the Rekluse, however not the chattering engagement noise that comes with the 2.0v. I'm getting ready to install my 2.0v here soon, but would like to avoid getting all that chatter I've experienced riding a couple of other Bergs last year. So, after I contact Rekluse about weather or not the 2.0v can be successfully mitigated (with or without a 3.0v upgrade), I'll let you know where I stand about purchasing your kit. Looks like you have it listed on ebay as well, so if it sells prior to me recontacting you, I'll understand.
Lastly, have you experienced and of the chattering issues I discussed above?
