Even if I were to buy it, that would only be 2...you'd still be the craziest FF around here!!!

If I win powerball before it sells, it's mine.  Absolutely no question.

I now have a new 19 tooth sprocket to put on, so will be switching it out soon.  In planning this project, do I need any new gaskets or o-rings or anything else while putting the covers back on?  Just want to make sure I have everything I need before I dig into it.

Thanks in advance

a new paper gasket for the cover and now would also be a good time to replace the seal on the shifter shaft as well as the seal for the clutch pushrod

Inspired by Patrick I did a sprocket cover split. Here are some picts for the bold and the brave. After cutting the cover, I continued and cut loose the oil funnel. After some grinding of the edges, I used model clay to fill the oil funnel and the recess in the new oil plug (see image). Then I filled the remaining volume with chemical metal (plastic padding) and put back the oil plug covered with a thin layer of vaseline. When the chemical metal had hardened I unscrewed the oil plug, and voilá, new threads. I have used the new cover for 5000 km, without any problems whatsoever. I finished the modification by changing the original gear linkage into a steel lever (originally for a YZ80, 93-). The lever was cut and rewelded to fit in the narrow groove of the shifter shaft.
Now I do not have to remove the side stand (and oil) to change the sprocket and chain. Shifting is more direct now as well.

  Excellent job & post Harre, thank you it's inspirational (read = experience is the thing you get just after you needed it unless you steal somebody elses)

Send me the remaining alloy fillings and and I will mix them with some pastic metal and cast a T3 bravery medal  :icon_salut  

Can I vote that post gets copied into the How To's it's so good.

As Obama said today, I don't deserve it. Credits to Patrick and others who paved the way. The mod is actually not so difficult, it just takes some nerve. Try it you'll like it.

This was back in October or so. How are those threads holding up now? How do you measure the oil? Thanks for posting this!!!

I've been thinking about this:

You can de-risk this project by buying another sprocket cover and moding that. This way you'll always have the original to fall back on.

Good thinking man.  And having a spare in case your chain ever gets a little loose and takes the thing out is good, too...

I wish splitting the cover apart would eliminate that situation.  I wonder if some sort of shim could be slid in there to prevent the two from ever touching.  My good friend Justin Case would like that very much.

From the photos it kinda looks like the two aren't touching now?

By 'the two' I meant the chain and the clutch pushrod housing.  It's so tight that if the chain gets loose it takes that out...and out goes your engine oil...
