Well maybe aloof you recall my past builds. First a custom turbo kit on a vector then moving the vector motor into a rev chassis. I have been riding a 1100t for the past couple years and this summer I decided I wanted to build something once again.
I am going to take what I learned from the first yamadoo build and build another yamadoo.
Starting with a vector motor(box of parts). Mpi supercharger and skidoo rt 1000 chassis. Should be fun.

YEEEAY!

Did a little work today. First thing first found some common rivet/hole locations on boths sides of the sled to work off of. Then build some plates off the jackshaft cast support to give proper location for the jackshaft on either side. This will help me to bring the engine square to the jackshaft when I set it in to find the best spot for it. This is a bit different than I did it last time.
Can't wait to get the block later in the week and find out where it will sit in the chassis with the yamaha ctc for the clutches. Then it will be a matter of poster board, then aluminum sheet and then taking measurements off the aluminum sheets to machine the thick billet aluminum into lightweight strong billet braces that the engine and jackshaft will be attached to.

Nice build, you ever ride around here? I see were not too far away from each other

If It snows enough to actually ride I love to ride around here. Sent you a pm.
^^ I'm not too far either

we talked about this project a bit on snowest...I too am putting the yamaha engine in a RT chassis. Im interested in following this. Is your plan to remove the stock mounts and fabricate sides to hold the engine and jackshaft?
I actually looked at removing the side bulkhead plates from my nytro and machining them down a bit to bolt to the RT chasis, but given where the reverse handle is I could not run the exhaust the way I wanted to.
Im interested in putting side panels on mine with a through bolt like the nytro but I was having trouble deciding on a plan.
I have the front where I want it but I am still working on the back. Im going to work on getting some photos up this weekend.

Yes yes, Nytro type side plates. They will be swiss cheese by the time I am done with them. Thinking 7075-t6 aluminum with lots of pockets to be lightweight yet strong. They will have the jackshaft bearing as well as the engine mounted to them so they will be the backbone of the engine cradle.
The pic is rough I know but it is just representation of my plan.

I see we were both a bit inspired by the new viper chassis.
I was looking at putting in a separate support on the clutch side, but you are incorporating it into the motor mount. Looks good, its making me think a bit more. Im thinking about measuring some distances on the Nytro chassis and basing it off those.

Definately inspiried by the viper chassis but was more inspiried by the nytro after doing the last yamadoo. The viper chassis doesn't mount through the top brace to the engine directly I do not believe. I believe my design will be superior to the viper.

Being superior to the viper braces due to the fact of how the procross/proclimb bulkhead it built. Really lacks in the front outside bulkhead area of a good spot to brace to. Definatly needs bracing for this area but not a good spot to hang a motor. The 1100T mounts on a single mount in the front middle bottom unlike the genesis 4 strokes.

Ordered some 7075-t6 plate this morning. For a great price. $90sjipped for a .375x12"x48". That should easily make my side plates I was thinking 6 wide may do it originally. 7075 is almost twice the tensil strength of 6061.
Also slowly getting my engine and supercharger parts in the mail. Here is a little taste of the block sitting in the chassis. I am amazed at how much bigger the bulkhead area is. Someone said 2" I think it seems like more. I was super restrained in the rev and I have all sorts of room to work with in the rt. it is much needed. I need to find someone with a vector that I can measure some points on. I have to make sure that the vector engine is centered in the chassis as with the super it is just as important to get the clutch side right as well at the mag side.
Either way here is a pic.

Are you planning on using the front cooler?

Maybe. . . But if I do It will likely not be used to cool the motor but something else. . . . If I use it It will be for cooling a water to air intercooler. I have to modify the upper inlet of the cooler for sure. I may just cut the inlet off for now until I get the motor mounting done.
