900 motor In a m chassis

[Mnt.Tamer]

I have a M chassis and I'm thinking of doing this but I'm afraid of the M secondary it's not as efficient as the KK roller secondary and I don't want the think to fall flat on it's face or have a clutching nightmare. what do you think?

It would be sweet to also install a CMX belt drive with a 900 in a M

I would think it would be easier to make a 1-M chassis into a M.

i second that...

Got a CPC 1150 for sale. built on the 900 case.
PM if interested.

How's the "builds" going guys?

Get the windage plates off that secondary!!!! What are ya, a flatlander? haha

 

[fishtank]

why would anyone want do do this?

Wouldnt the 1000 motor have more power and torque than the 900? Its already sitting in an M chassis ready to go.

I think I saw somewhere on the block that the "900" motor is actually only 867cc's or something, so it only just makes it a 900

Tell anyone that's ridden both which has more grunt and power......hence the thread.

Yeah ive ridden both. My 900 def has more kick off the line but I thought that might be due to the twin pipes or the larger track getting more grip in the snow.

My mates 1000 only has a 153 track so I thought that was where I was getting a better start off the line.

Nope, I have also ridden / owned both and without a doubt the old 900 has more bottom end grunt !
I am toying with the idea of putting my 900 motor in a 06 rev chassis. I think it would be a much easier job then making it fit in the m chassis.

First thing you need to find is the engine plate. Chances are pretty good who ever you find that fabs plates for the M-series can drill the 900 engine mount holes. If not, you can drill them yourself with a clutch alignment tool. Just make sure the center to center distance is correct and you have some secondary shim adjustment both ways.

I put one in a Polaris Assault chassis and the hardest part was being able to use the 900 front engine mounts. I got them in by bolting them to two 2"w x 8"l 1/2" strips of aluminum plate that was bolted to the bulkhead a couple inches under the header.

I have a few threads of conversions I've done in the member sled builds section, I just posted pics of the most recent. It is a tricky build but very do-able and awesome torque in a lightweight chassis.
