How Hard to Install a RK Tec "Fix It Kit"

[99slpss]

Hey guys I am looking at tackling this project, I am doing the Pistons and Head but have never dug into a two stroke. Is this a pretty easy process? Is there any part to really pay extra attention to?

What will I need for other gaskets, parts, etc when doing the install?

Any more pointers and advice would be greatly appreciated!!

The key is making sure everything is extremely clean when going back to together. Intake needs to be spotless. Clean up the pistons, cylinders etc with brakeleen and give the pistons a nice coating of oil just before you install the cylinder. Make sure if any coolant didnt get drained and ended up in the crank or anything that you clean it out well.

RK tek instructions will give you all of your torque specs etc.

Don't install the pistons backwards. (If you can on this engine. I tried once years ago on my first rebuild, didn't work.) 550iq

What is the preferred method for draining coolant? I'm in the process of a rebuild on a different sled and I just pulled a hose lower than the cylinders to get it down. I see some vids it looks like the just start pulling the engine apart and let it run wherever.

Using something like this is by far the easiest cleanest way.

I angle a small anti-freeze siphon hose down a bottle hose and squeeze or pump away into a clean container. Open the bleed screw. Reuse the coolant. Or just drain the bottle down well, pull the heads, then suck out through the cylinders. When just doing the top end with the motor in the chassis, you can just about avoid spilling any. Pros are very easy to bleed, too. FWIW.

I pull the main hose off the bottle and pull it down draining as much as possible into a container. Then put that hose back on and pull the hose coming off the bottom front of the motor and drain as much as I can. Pulling the cap of the coolant bottle after you have the hose off and in your container helps it drain. Then put that back on and pull the hose coming off the thermostat & head and drain that. Shouldn't be much in there. At that point you should have more then enough out to do the top. Coolant is reusable if you want and very little mess. The key is getting each hose as low and straight as possible as you drain.

Super simple method and takes about 5 minutes. You can also throw a shop vac on the hose and suck it out if you dont care to save the coolant.

I like the second method as I wanted to put fresh coolant in anyway! Are the Pro's a a pain in the *** to get all the air bubbles out when refilling the coolant?
