Added another X4 to the fleet today y

I'll get some pics later, but I can say that it doesn't appear to have ever had an aftermarket exhaust; all the manifold bolts still had paint on them. The larger water lines on the back of the motor appear to have been T'd at one time though

Small update: I got the motor pulled and hull cleaned up some.

. It cleaned to pretty good considering all I had was some dollar store cleaner. You can just see the hose in the top right appears to have been T'd before. I'm assuming for the front discharges

It's been a busy few weeks around here, so I haven't gotten a ton done on the ski, which has been named the RXP (for Red XP). I did get new fuel lines installed as well as get the top end of the motor pulled apart. When I got the jugs off this is what I found: MAG side

And PTO

I'd say it got a little warm! Needless to say this piston and cylinder is toast but luckily the MAG side cylinder walls were fine. I have a spare stock jug and piston laying around, so I ordered new rings and roller bearings to reassemble this motor since the MAG cylinder is still in spec. I know that a full rebuild is the best option here, but being that I don't put a ton of hours on a ski each year and this one will be getting sold in the near future, its worth the money to prolong a rebuild in this case.

Also, can anyone ID this plate? Neither of my other XPs have it.

That plate is a cover plate because it used to have a UMI on it. Look on the inside and see if you see holes that would be covered by that plate near the corners.

Yup Racer is right on the $$$....

Well, nothing too exciting has happened with this build. I replaced the scored piston and cylinder with one from my parts ski that was still good. After hitting the cylinders with the hone and putting new rings in, I taped everything up and gave the motor a coat of paint

Motor waiting to go in. How's this for a (messy) garage full of X4s?

Also, I think I figured out why it didn't run. I found this when I opened up the carbs:

Rebuild kits will be on order soon. I go back to school soon, so I am trying to get as much done as I can in the time that I have left. This weekend I hope to have the motor aligned and locked down, pump and some exhaust installed. I've also decided to pull the intake grate and sponsons and replace with stock since they won't really affect resale. I'm either keeping them for another build or they will be up for sale soon.

question... do you have to put the lower pipe section in before the engine?

Either before the engine, or unbolt the motor and rock it out of the way. Its very difficult to get it in otherwise.

cool ,, thanks!

you can get it in by removing the front e-box and sliding it in from the front storage compartment, tight fit but it works.
