J’s Dirty 30 north truck

[TeknoJ]

Well after much frustration with this engine never running I’ve decide to send it back and ask for a refund. I just received it today from the seller, I had sent it back so they could figure out the issue. “Just needed tuned”. Well it won’t even start for me so……? Then I see how leaky all the gaskets are. This is the exact same condition I sent it in. Leaky crank seal and wouldn’t start.

I pulled this motor apart and used some yamabond on the gaskets and allowed it to cure. I also got a copper exhaust gasket and used a little copper exhaust gasket maker for any gaps and allowed it to cure. I pressure tested this motor and it held @6 psi for a few hours. I bumped up the pressure to 10psi and it lost a half pound over night. I no longer have a hand vac to pull a vacuum on it.

I decide this was good enough, I reinstalled the motor, pipe, and carb with a clean filter and new spark plug. Well the damn thing fired right up. I had set the idle screw in quite a few turns just to make sure it would idle on its own and began adjusting the low needle and backing off the idle until it hit a good spot to begin driving it. I’m trying to achieve the smallest idle gap possible without going lean on the low needle.

I drove it for a bout 2 minutes until it died as I was adjusting the low needle and idle again. Then my pull starter broke. It was engaging the flywheel.
Yada Yada Yada, I fixed the starter and took it back out for a drive.

I think I got it dialed in but the pull starter broke AGAIN.
If you skipped down to the last line then:
IT RUNS NOW

I'm happy to hear that! Air leaks on a 2-stroke can cause quite the headache.

HeyI read the whole thing.

 

[TeknoJ]

It’s a long frustrating read!
I was able to fix the pull start and we gave her hell last night after dinner. Runs great. I can’t believe I had so much drama with this engine.

Sometimes it happens. I had a plane that that gave me nothing but problems and I was seriously ready to scrap it, then one day it all just clicked and was great from then on.

Well, it's awesome you figured out what the problem is. My dad was a wizard with engines. I had a 1978 Yamaha XL1100 bike and it ran rough. Nobody could figure it out. My dad noticed cracks in the manifolds and said yep, you got a vacuum leak. He smeared silicone on the manifolds and it ran perfect after that.

This thing is a crowd pleaser

We brought this beast out to Howe for some WOT thrashing. I think it needs a bigger pinion, we’re slowly creeping in on that perfect tune. The kid is driving it, so please excuse the cautious throttle work. He’s really easy on it.

 

[WickedFog]

That is so wicked dude!

I wish he could film while I drive

Dang dad. Kid done pulled the wool over your eyes. He can!

I grew tired of my Victory pipe walking around so I came up with a simple solution. I TIG welded a piece of stainless tube onto the pipe and now I can bolt the pipe to the engine and the chassis. No more melting the plastic dirt guards.

Welding a washer onto the tube was HARD, I also welded a dime to the end of the tube to cover the open end.

 

[TeknoJ]

I’m going to change things up a bit.
I painted some wheels last night and landed on this color.

 

[TeknoJ]

I’m going for something to this effect.

That just looks too mean. Like it might bite you. This might be a bit nicer to deal with
