As for your throttle cable , you could try to first go to your left before heading back to the right to "waste" a bit of cable while at the same time, not putting any drastic bends in it. I use those nylon zip ties to keep the cable in place. It would help if you explained why you want to remove your muffler as I don't understand what is going on. Good luck!
Is this a new build? If so, i would like to offer a few pointers that will help parts last.
I have to replace the muffler as it's tip feel off.. There is not a proper casket put between the exhaust and the engine. Due to this you get unburned oil and the exhaust vaporizing on to the head of the engine. I would not say it's a new build. I got it last year and had to dismantle it where I was living before. I ended up trading the motor for a bike trailer. Then earlier this year I bought the motor back on a bike this time from the same guy.
I've never been good at changing links in a chain and I don't even want to attempt to. Anytime I have it's never gone well. I can never line them up properly and the chain becomes stiff in the spot I changed or took out a link.
I'm relieved to hear that the engine being easy to move is normal. I thought it was but as I said before, I'm new to this and I'm learning as I go along. I'm happy this motor was not perfect when I got it back from my buddy. The reason is that it has taught me a few things about it and how everything works.
