Just curious how long this takes. I've done V8 motors before, but I was needing to know how long it takes you to do the whole thing. I want to make sure I set aside enough time to get it done during a weekend. I also plan on getting some stands so I can easily do the whole swingarm maintenance and tire changes on my own.

I think a trip to Sears is in order for a jack and to the dealer for a rear/front stand. :)

Once I get those, I'll be kissing the centerstand goodbye. :)

I'd PM dotsony; from this thread (http://www.ninjette.org/forums/showthread.php?t=13492) it seems he learned some things that he'd do differently the next time he adjusts the valves.

The first time I did the valves, I took 2 days. The first day, I took the bike apart. The second day I did the valves and then synced the carbs.

I could do it in a day, but I like being fresh when doing the valves.

Since you've done valves before on a V8, you'll probably breeze right through them.

If you have the whole weekend, you should have more then enough time. Don't forget to sync the carbs afterward!

I need to get the kit to sync them. Maybe I'll head to the dealer later on this week to pick it up.

I made my own sync tool from the directions at:

It's called the "Two Bottle Method".

It's real easy to make. The only hard part for me to find were the hard rubber stoppers, but I finally found them here:

There should be a place similar to that around you if your not near one.

You should be able to take everything apart, check/adjust the valves, and put everything back together in less than 2 hours. If you have the valve adjustment tool, don't take a lot of breaks, and don't drop anything in the engine, expect it to take considerably less amount of time.

Here's a shot of the valve adj tool I threw together when I realized that I couldn't do it with out one. a 1/4 dr socket a piece of flat stock and a little heat.

I also took some 8-32 thumb screws filed them till they fit in the air adj screws and soldered them together. Can't find the completed pic but I can adj them with out the need for a screwdiver.

Later
