    The new/old 750 that has come to live with us has a little issue I want to ask the group about. It has stuck in first gear twice now. Is this something that bike is know to do? Its not jumping out of gear like the 1100s but is not coming out of first with out some jerking around on the shifter. Maybe the return spring or the hold down on the shift drum? Any ideas before I begin the exploratory?

    could possibly be the issue where the primary chain guide starts to crumble and bits get stuck in the shift drum there by causing shifting issues. I have seen it talked about a couple times here.

    Would I have pieces of the guide in the filter or the pan? We changed the oil again last night and put 60 miles on it this morning with no issues. Could have been something sticking from the years of sitting. I'm thinking thats what it was. Thanks for the responce. If the problem comes back I'll restart this thread

    I noticed mine shifts alot easier since I switched to synthetic oil. I run synthetic oil in both of my bikes and they run better and shift better with it. I run Royal Purple in my Yamaha and Amzoil in my Honda. More miles between changes too.

    You can adjust out the "Neutral Fight" and "Clunking into Gear" by adjusting the Clutch Cable Slack Knurl on the Clutch Perch to remove ALL the skack in the cable and give you MAXIMUM Throw-out!

    Feel the Cable down at where it attaches to the throw-out arm.
    You want to have it as tight as a guitar string.
    Zero lash.
    Get all the slack out and then you can make further adjustments to the tightness if you take-up too much and the clutch slips.

    Try to get all the slack out of the clutch cable. Once you get the maximum throw out, the Neutral Fight stops and the Bike slips into gear without a lurch and a clunk.

    Sweet Baby Jesus... I hope you've saved the day, Rick. Mine has minimal slack, but I know there is a touch of play.

    Rick I road on the bike that Wing nut is referring too, beautiful machine BTW. This is defiantly not a cable issue. It got looked on me when I road on the 3rd. I physical held the throw out arm all the way because I was thinking the same thing (clutch out of adjustment) but I assure you it felt jammed. I'm going to look behind that side cover for debris next time I get down there if wingnut doesn't do it first.

    I've seen a few Bikes with the Clutch Cable adjustment all messed-up.

    The KEY to getting the Maximum Throwout is the correct positioning of the THROWOUT "ARM" at the Top of the Shaft that goes down into the Case.

    You need to ROTATE the SHAFT to get the End Play out of the Pinion Gear
    Position the Throwout Arm on the Shaft while keeping the Shaft Turned
    Then, attaching the Cable End and Pulling the Cable Sheat Taunt at the Cable End Adjustment Holder to the rear of the Clutch Case.
