So I guess the question then is the '10 clutch different from the '04?
My sheet says 00-11 for both part #s BUT DOES NOT show a Z-Start available now, just the Core EXP and the Core Manual
EDIT add info-, Being a new dealer (only 2 months) I called tech support and got some info-
The Z-Start is no longer available and they have no plans at this time to offer a Z-Start Pro, @ $629 for most apps, for the Gas Gas line even though the Z-
Start Pro is described as 'bulletproof'. He did not elaborate but I would assume it's the same thing we run into now with aftermarket- not a high enough bike count.
The Core manual @ $519 is as it says, a manual clutch, but very high quality components ( I didn't have time to itemize parts in the kit).
The Core EXP @ $899 is the high dollar one and is the only 'auto' clutch they have available for Gas Gas.
The EXP @ $399 is a lower money setup that sacrifices some of the stock clutch plates to allow for the plate to fit in the basket and in their testing they were not comfortable with the durability of the GG clutch setup when plates were subtracted, thus the 'no EXP available' problem we have with the Gas Gas line.
Probably the only hope to find a Z-Start for a Gas Gas is to watch the part outs or find someone that wants to upgrade to the Core EXP. Hope this helps
