Here is a picture of the exhaust setup out getting welded up. It is a 1.75 inlet/outlet flopro bafflepack. Im hoping the baffle chambers will keep this a bit quieter than the straight through glass packs. Ther will be a turndown welded on the end at a 45ish degree angle pointed to the bottom edge of the tunnel.

Newly powder coated front and rear bumpers

Did you replace the crank seals in your little 340 Polaris? 90% of my old 2-stroke failures were due to bad crank seals, especially PTO.

I have several old Polaris, my favorite being a '78 Cobra 440. I have never had the motor apart, except I replace crank seals every 5 years or so as PM. Base, head and exhaust are all original.

I would like to see the end product if you go pics of that. I don't know about you but I love working on sleds and doing this type of stuff. Now rebuilding motors is another story but thats why I bought a Yamaha

I didn't but when I get it back together I'll do the spray trick around the seals and see if the idle rises. I don't have the tools to pull the clutch or the experience so I would let someone else do it haha

Got two of the arms bolted back on with blue loctite. The Oilite bushings have been a giant pain in the #*$&@ I ended up having to sand them so that the sleeves would even fit.

Getting creative with my wiring for the brake light.

Got some pex tubing to run my wires through.

Another picture of the arms. Think they will look good once it's all back together.

 

[Deeppow16]

What was the problem you were having with the oilite bushing? trying to get them in the a-arms?

 

[NytroMisfit]

No the aluminum cross shafts were not even close to going in. Sanded down the inside until they when in nicely without binding.also had to lighly sand bushing flange because it was pretty tight in the mounts

O ok I just put oilites in my sled that's why I asked. I didn't have any problems putting things together. They were tight but not to the point where they wouldn't go in.

 

[NytroMisfit]

My control arms were so tight they were seized
