    Hi there everybody. I am a new member, but long time fettler of a TX750. I am wondering if someone could give me a brand new starter clutch sprocket diameter dimension for where the one way clutch runs.

    My TX750 sprocket is 41.90mm and I suspect it is a little worn.

    Thanks very much, Tony

    Welcome! :freaky
    I have a new one squirrelled away in the original paper... somewhere, as long as you're not in a hurry, I can get that number for you.

    OH MY!! That's not good.

    Have you contacted Avon about it.

    There was another problem with Avon sidewall's cracking. It was in the Suzuki GS community. But it seemed to be a certain size that had the problem.

    My particular Suzuki took a different size than those that was having the problem. I've had no issue's with mine.

    Now I'm afraid to put them on my TX since obviously your having problem's. :huh

    How did it turn out.

    Got it on both the 18", and the pizza cutter 19" on the back of the Norton. It hasn't bothered yet. I didn't contact Avon, quite frankly, because my days are so full, and I reaaly can't bear to listen to some punk tell me I must have run it under inflated, over loaded or too fast. It hurts, I have to save my self for bigger fights, lol

    Hi Concours, I received some feedback from a parts distributor that the dimension is 42.17mm.

    I am going to try the XV250 starter clutch upgrade to my TX750. With a new TX750 sprocket, I should be fine. While the XV250 sprocket is an overall larger diameter, it is the same dimension as a TX750 sprocket where the starter clutch runs, so I feel confident that the XV250 starter clutch will work with a TX750 sprocket, and the XV250 one way clutch fits snugly inside the TX750 flywheel.

    I'll drill some new holes similar to what Argo has done with his Borg Warner clutches.

    Hi Concours, not to hijack this thread with tyre talk, but your tyres look like new stock that has been sitting for a long time on the Dealer's shelf. You have probably made this assessment yourself. Out of curiosity what is the date code on the tyres? They might be quite old.

    Hi Tony, Not sure how you arrive at that... I bought the tire from Motorcycle Superstore in spring 2010, the bike is stored indoors except for when it's being ridden. Here's is the sidewall info. What do you think?

    The tire was made in the 38th week of 2009 (3809). Not that old.

    Those TX750 starter clutches look an awful lot like the well-known POS in my Honda CB450K5. And the portion of the sprocket the rollers run on is 42.16mm in diameter. Hmmmm...

    Little update to starter clutches. These will be different design, fully hardened to 55 HRC and come with special bolts.
