^ that helped

New problems... what is a magnet key and why does it matter?

I'm about to just put this thing back together and I'm almost sure its not gonna work. How does it know when to send a spark?

If anyone can tell me how to fix the problems I'm going to have after I figure out which pieces go where and throw it back together it would be much appreciated. Timing, but what else?

Are you talking about the woodruff key? It is for the ignition timing - when to send a spark. No parts should be left over.

Good Luck,

Boost bottles....NOS..... if your having this number of issues you should remove everything but the stock parts. Make it run correctly first then ad performance parts, not the other way around. Just my 2 cents.

Good Luck,

While taking the engine apart to replace the crank case gasket. I found this little half moon shaped thing that was apparently the woodruff key. I found it attached itself to the magnet.

At the time I thought it was something completely unrelated to the engine. (I have lots of small circle magnets with my tools and a few broke in half) Now I cant find where it goes or how to put it in. Much less the key itself.

There is so much info on here about how to take things apart but how do I put it back together?

The clutch makes a terrible grinding noise. After I try to start the thing there are little metal shavings all over the place under the clutch cover. I adjust the clutch over and over again. The engine tries to start once or so then the clutch wont engage at all anymore.

^^ that apparently shows me where the woodruff key goes but I still cant figure it out.


Anyone know how or where to put this little half moon shaped $3 part that keeps me from knowing if my engine will start or not?

Boost bottle was to fix the problem. I've heard on here that gas/oil in the fuel filter is "normal" and the boost bottle will help to FIX that normal PROBLEM. I didn't like cleaning my air filter out every time I ride for 10 - 20 min.

NOS... I didn't buy a engine kit to ride it stock. This is my only transportation for AT LEAST a year and a half from the time it works. I want it known that I will be running NOS when it is fixed or when I sell it and buy a new kit. I dont know enough about engines to know that a standard head gasket/ piston / piston rings. etc wont destroy my engine when I do put the NOS on.

I've already taken the boost bottle thing off and sealed the hole in the intake. I just have a hole in the air filter now with a small vacuum hose attached to it that is bent and wire tied so if it ever runs again and the filter clogs with fuel I can just open the hose instead of running it without the filter to get home.

Thanks though. You do have a good point. But so everyone knows. This is exactly what I am trying to do
