Just look at that clutch http://www.huztl.net/Free-Shipping-...patible-With-STIHL-070-Chain-Saw-p435087.html I am going to go ahead and start this thread. The kits are expected to be ready no later than 1st part of May and then a little more time to get them to our door. They have a huge trade show there the middle of this month and they have been busy or it would have been out. You can buy the prebuilt if you want its ready to go. I would like to present an idea to those that would never consider a big saw, now is the time. We have an amazing milling section here. But the ultimate chainsaw is almost at our fingertips . When we get the saw kits we could order a 090 66mm jug kit QG09066 (does not show on website yet) and update the clutch to the 6 shoe clutch 1109 160 2200 and there is a thread currently on that clutch. http://www.arboristsite.com/community/threads/stihl-090-6-shoe-clutches.307878/. this kit would become the basis for a real monster 137cc saw. its a huge saw anyway but put the 090 goodies on it and bam. It would be great if a bunch of people bought the kits and we figured out how to do the conversion which is doable. Guessing here...If the 090 clutch is 150 and the jug kit is 60 and the kit is lets guess 230. 440$ Its turns around 8000rpm so its a grumbler. we are used to dirt bikes this will be more like a tree Harley. and when they come out with the drills and winches and if you can have this saw to mount them to, wow, another use for it. pulling cars out of ditches or moving hay up in the loft is what you could tell the wife.
