Do you have to pull the motor to get the jugs off a 900?

I've done it without pulling the motor out of the chassis, but I have to take the motor mounts (and throttle bodies, etc...) out so I can tip the motor forward. My fingers and coordination prevent me from getting to the injectors any other way.
No ,you do not have to pull motor .just make sure pistons are on the full down stroke when you pull the jugs, you can look inside after you take the Y-pipe off and see cyl's and pistons.
900 Cylinders
On an 05 you can remove the cylinders without pulling the engine because it has the two injectors in the case. However on an 06 it has four injectors, two in the case and two in the cylinders.
In my opinion it would be easier to pull the engine if it is a 06.
Hope this helps.

Save yourself alot of aggravation. Pull the engine, and do it on the bench. The lower bolts holding the fuel rail are almost impossible to get at, even with the engine rolled forward.
Why do you want to get the cyls honed if you are NOT replacing the pistons/rings..???
I also think it is best to pull the motor if you want to remove the cylinders... it is not very hard to get it out
Plus you will be able to check the motor mounts well, clean out the filth under the motor, replace all of the motor mount bolts with grade 8 fastners, clean the oil pump well etc etc.... easier to work on on the bench....
Also, when you pull the motor, remove and leave out the lower-most bolt in the recoil housing... this is impossible to remove unless the motor is out and does not compromise strength. Very handy when you break a pull start rope.
Also, you can tell if you have the 2006 pistons thru the exhaust port, without pulling the motor.......I recommend that you remove the Y-pipe.

Thanks Eric for that post. I didn't know their was any more action on this thread. I did pull the pipe and Y pipe the other day to look in there to see if I could tell. My problem is w/o having one year piston or the other in my hand, I can't tell if the ring-land is narrow or wide. Nothing to reference them too. They looked like the '06's to me, but could be the '05's still. I am going to pull the motor anyways for a summer project. I have this stupid coolant leak from behind it somewhere I can't find anyways! Thanks again.

PS I was only going to have the cylinders honed if it needed the new pistons in it.

I believe you should not hone nikasil coated cylinders, they don't need any work unless they are out-of-round. Honing them will damage the coating. If your compression is down, you may want to have a look at the rings but that should be it.

Does anyone know the piston brand SPX.
Know the general discussion here says to use 2006 pistons.
Always looking for a better mousetrap !!!
don, indydan said those pistons were based off of the 05 piston and the only piston he would use would be the oem polaris piston.
Why do you need to have the pistons on the down stroke when you pull the jug off?
