You guys probably already figured this out, but just in case I'm going to post it. Today I went to set my mixture and idle but found my rpm gauge wasn't working anymore.
So, what I did was this.
1. Turn the idle screw up until the back wheel starts to spin.
2. Turn the idle screw down, very very slowly until the back wheel wants to spin but doesn't.
3. Adjust fuel air mixture, if back wheel starts to spin the rpms went up! Start back at number 2 and keep going until back wheel doesn't try to spin on mixture screw and you are all set.
Tada!

CVT / crankshaft is good to go!

I think based on the fact that I hear it when starting it but not after it's running it has to be the starter. I got some m12-1.25 nuts, I'm going to go see if I can salvage the crankshaft and if so, I'll worry about the starter next.

Here is the crankshaft thread and nut:

for the crankshaft nut, I found this one pep boys website, I'm going to pick one or two up and try it:

I changed it around 100 miles, currently its at around 500 miles. I will change it again, but first let me see about this crankshaft because if I can't get that to work it's time to junk this thing.

The stuff on the plug looks and feels like graphite.

Not a backfire, I think its coming from the starter but not 100% sure. I won't understand why the sound doesn't transfer in the video, I can clearly here it.
Anyway, I need to get new nuts for the crankshaft, the current one is thread less and hope I can salvage the crankshaft itself, before I put it back together.

I just went and tried again, and again I here it but once the bike starts its fine.

I went back and listened to my video and for some reason you can't really hear it in the video. When I was doing it I heard a loud bang, sort of like a back fire...

Ok, got a couple of things for you...
First, when I cranked it over it popped my finger off, which is good news.
Also, here is a video showing the spark plug:
Now for the crazy part, I recorded a video of the sound, which happened, but while I was doing it the bike started up and ran fine:

The noise is there with the variator off.

I think I can salvage the crankshaft, there seems to be enough thread left, but I need to pick up a new nut.
I turned the variator and everything seemed fine, no wobble or strange noises.

Is the shaft the variator sits on called the crankshaft?

Also, it looks like I need to replace the shaft that the variator sits on. I completely stripped it last night. Is that even replaceable? Actually, I think there is enough thread left that if I replace the nut I can get it back on. This morning the bike started right up and ran for a minute, then stalled. When I tried to restart it, I heard that loud banging noise so I stopped. It sounds like its coming from in front of the back wheel and just past the CVT, like the middle part of the engine. |
