    Other day added light bars to my XJ550, thread is in the XJ Modifications section. Scroll down for the pics because the first links I used in my original post weren't working.

    I'm totally bummed rode my yellow seca this past weekend, long story I think the starter clutch is totally roached . This is my spare engine and has been fine ...until now . This is now worse than the original engine, so I guess it is time to do the deed and tear into orginal engine and replace the starter clutch ...I even tried another starter ( always nice to have spare parts ). At least my Johnny Cash bike is running great so not without a bike .

    Cable lube for XJ650J and XJ700J. Not my favorite job, but you gotta do it.

    Once you get the motor out Jetfixer you will split the cases quicky. I had a big problem getting the cylinders off the cases and the two front studs at the head cylinder joint were seized. But if you can leave the cylinder head on the motor it's not so bad.

    Found this on a 6 year old thread. You should try these methods before attempting to change out the starter clutch. Thread is called "XJ750 Starter clutch going out?

    Really? Well that gives some confidence for the time when it happens to me. It's one of the horror scenarios on my list now :)

    No it's easy once you get started a big job is just a lot of small jobs one after the other.

    I had to remove the head and cylinders due to the starter/alternator chain. It was quite bad and needed replaced. Once all the bolts were out of the cases they separated easily.

    Went for a ride out for a hour or so and thought why not change the rear gear oil, since it’s recommended to be done after a long run. Don’t think it has ever been done before. The magnet on the drain bolt had lots of fine gunk and the oil itself was not pretty. Plan to check it again after a few rides to be sure it doesn’t look like that again too quick.

    My starter clutch also sounds like a box of rocks only when hot. The people I ride with always look at me like, oh no is it gonna start, so I’m dreading that replacement.

    Starter clutch is not so bad to do just time consuming and the cost of parts. Plenty of help here.

    I’ve been following the previous posts with interest and it doesn’t look too bad, but will be the most in-depth repair I’ve done. Project for the off season….

    You might be able to repair your starter clutch with the top end of the engine in situe. That is better as the only reason for total engine strip down is if the starter/alternator chain is worn. Even the cam chain can be renewed if required with a joining link. That's how is was done in the factory during engine assembly.
