I'm still trying to figure out this whole Internet thing so forgive me if this is user error, but the following URL returns an error:

I had found the document from ghnl's signature, so I thank him for providing it to us.
After more than a year of ownership I'm finally ready to start work on my 86 quad. Just this past week I replaced the drivashaft support bearing, idler arm, center muffler and flushed the brake fluid. The car drives wonderful overall but has a slight exhaust pop between gear shifts, which I attribute to a slightly out of tune fuel system.
I had previously reviewed the tuning doc referenced above, but since at that time I was unable to work on the car I never printed it out.
