The guy who works at the vehicle mechanic shop where I have the bike parked now says he believes it is the timing chain.

I really doubt this, because the bike has less than 12k miles, and I just did the verslavy mod about 2-3k miles ago. Any thoughts on this?

Oh I assure you it was quiteflammable We were playing around with it and a torch before we tried it on the bike..

I feel that I'm sure that it is getting gas because I put my hand on the carb covering the hole coming from the airbox and it was wet with gas after.

Did that already man.. I am feeling really hopeless at this point. It's gotta be a small problem. Do you think timing might be the culprit? It did start once, but it ran very poorly, which I thought was because of gas not timing. Is there any other way to check it than to open the whole side cover? There was no timing chain ticking before I replaced the jets, I really don't think it's that

Shoot some starter fluid at it, once its running its a lot easier to see which way it needs to go,

Now thatsa gooda questione' righta therea,,

& ya gotta keep that battery Hot,, it'll turn over , sounding like its spinning just as fast as it needs to to crank ,, but the shparkinmaker ( See? I speak German And Italian)wont be sparkin,. If you wanna check spark, leave the plug in ii, put the wire on another plug. That way the battery is fighting compression.

If its backfiring, firing out the intake of the carburetor or indicating like its perhaps even kicking the motor backwards at all. Then I would suspect the timing is off.

When you changed the plunger did you ziptie the chain or anything, or could have the chain slipped and jumped a tooth?

If it is backfiring then you also know that you are getting a measure of spark at least and perhaps fuel. So you can usually rule those out, unless you are only getting a reaction when you are shooting starter fluid in there.

Some of the simple things after eliminating timing, fuel supply, and spark would be to change out the plug and ensure your gas isnt old or contaminated.

Aside from that if may need to be looked at internally.

Id also be tempted to use a battery that I know would give it a good strong crank, such as a car battery or something. Just to make sure its getting a good starting speed and a fighting chance.

Right behind the tensioner I had just used a small ziptie and tied the two chains together to keep it from getting slop in it while I messed with the tensioner.
