Hey Folks,
First post here since becoming an Apex owner and I have a few rookie questions so please excuse my ignorance. I have been a doo guy all my life and recently experienced some major issues with my 05 Mach Z so I threw on my life vest and jumped ship to an Apex RTX on friday and put 350 fun filled miles on it over the weekend.
I have been digging into my doo TRA clutches for years but never once have I pulled off let alone disassembled a yamaha primary or secondary. Is the disassembly the same as a doo primary? or do i need other tools in addition to the common puller and holder? Is it similar in theory to a doo clutch inside...remove the govenor cup and I'll have access to all the goodies? I have a feeling their are probably some inside yammie secrets and know-how that I will have to figure out.
On the bright side, I absolutely love my RTX and cannot wait to get some more mileage under my belt.

The Yamaha clutches are great to work on! All you need is a puller.

MattZx6, good to see you here. I am IDOO1000 from the other site. I also switched to Yammie this year after riding Doo since 78. Hope to learn as much as I can from this site. There seems to be alot of great people willing to share info here. I have just under a thousand miles on my Attak and absolutely love it.
hey buddy, good to see some familiar faces around here!
So I don't need a holder?? Pull the primary bolt, thread in a puller and it will come off?!?!

One thing I do on the Yamaha secondary is draw a line on one of the towers down across the outside face of the sheave. You do this so if you take it apart you can line up the mark on the tower to the mark on the out side face of the sheave. The clutches are balanced from the factory and this helps to reassemble it the way it came apart.
When you take the primary cover off, turn it over and look at it. There is an X on the inside of the cover. There is also an X on the spider. You need to line those X's up when the cover goes back on. Again this is for balance
The Weights and rollers are retained by a nut, bolt, and a set screw. If your going to be doing a lot of tuning you can remove the set screw completely. That way you don't have to loosen and tighten them every time you make a change. the purpose of the set screws is to increase bushing life in your wights and rollers. I take mine out as some as I take my clutches off because they are a pain in the #*$&@.
You will also notice that the bolts all face the same way. When you take a primary apart to install new weights or rollers do one tower at a time. This way you can look at the other towers as a reference on which way to put the bolt back through the roller or weight you just changed.
I hope this info helps

Any good Yamaha clutch manuals?
Are there any good clutch manuals available that pertain to the Yamaha clutches?
More so for just maintenance.

Cameljockey and Mattzx6 Im also over on dootalk I have a 1000 mach z that is still kicking around. Play with it a bit but honestly its no match for the supercharged yami Im having a good laugh in that recent post about its performance. Appearantly a SC 4 stroke gets terrible mileage blows up all the time and doesn't work properly? I guess none of them have heard of MPI bolt on and go haha Im so impressed with how simple everything was and how easy tuning was.

That same joker that says they get bad mileage and blow up all the time told me I need 250 horse to keep up to his mach on top. I had a 05 Mach and the way I see it if I had 175 outta my Attak Id blow em away!!!
