Have a 2006 MTS 620 Standard with what I was told by the first owner is a 750 replacement motor- UA26022294. I bought a clutch pack that was supposed to fit both motors but discs were 1/4" too large and stack was 16mm short. The inside of my basket is 133mm and height is 53mm. Have not heard back from Oregon dealer on which clutch to order.
Any advice on which clutch pack to order? Thanks.

Mine has 11 friction plates. The dealer got back to me and they advised to read the part # on the basket and they will know what to order from that. Just ordered an 11 friction pack from valtermoto. Will let you know if it's correct.

This doesn't make sense. A 750 engine would have come from a Monster or an SS. And would be too wide at the swingarm pivot point to fit into the MTS frame, or to fit the swingarm onto. Most people won't do the work just to put a 750 in...

I know because I put an 800 Monster engine into my 620 MTS. We had to machine a little off each side of the swingarm area to make it fit. And the 800 has the APTC clutch.

A buddy hereabouts had an MTS620 which the dealer put an 800 in after a sidestand was broken out the crankcase. Story on mine is the same I am told.

I appreciate learning what fits and what doesn't on these bikes. Thanks for sharing your experience.

yeah, it smelt a bit like sellers bullshit to me too, but you never know. maybe it has 88mm pistons in it?

Received the Adige DU-112 clutch kit today and the dimensions are correct for my basket. It is listed as an original replacement for 2004-on 620,696 and 800. While you're here am not sure if the seller was BS-ing me that this motor will go 12k miles between valve adjustments. It has over 40K on it and is within 1k of his recommended interval and it runs strongly. What is your advice?
