Lester Mags

Trying to sort out some Lester Mags for my 73 Z-1. Have searched this site and Googled many sites, but not finding much info. Are these type mags suitable for tubeless tire service? If so, what type tire valve should be used? I have the 18" & 19" front, and the 18" & 16" rear. The 18" rear is set up for rim locks, so quessing that it is a tube type. The 16" rear does not use rim locks and has a large hole (0.6150) for the tire valve. Some written information from the Lester Wheel Co. would be nice, if such a thing exists. None of the mags have the word "tubeless" on them. Any help will be appreciated, as I'm just about Googled out on this hunt for info.

Thanks, Larry

I think all the mags that were able to be tubless were marked as so,

Use tubes. And go with 19/18 set up. You can find them on ebay often. 18 rear drum is a little harder to find but be patient. Oh and be ready to shell out some coin for them. If you need more info on them u2u me. There is a member here with that set up.

I have a pair of Lester mags that I am going to paint/ polish up for my z1a.
However I am not 100% sure they are the right ones and I would be very gratefull if anyone who does run them could tell me what the width of them is measured across the outside of the rim.
When we used these mags back in the 1980s we allways used tubes on them.

Found this link to a Lester Wheel Catalog kawtriple.com/mraxl/
Talked with Jim from Redline, he knows a lot about the Lester's. Slowly getting up to speed on these mags.

Thanks for the help, u2u to arai60 Larry

hey thanks for that link, i have sussed it out now, I was concerned that the rear was too narrow as I had Lesters on my z1b 20 years ago and i knew the rear on that bike was wider than standard. looking at the link you posed they list 2 different widths for the rear 2.15 Std. and 3.00Opt. so I guess I have the standard rear. At least I am sure they are for a zed now.

So next question does any one know wether the wheel bearings/ spacers are standard kawasaki ones or not? As the wheels I have do not have bearings in at the moment?
Any help gratefully appreciated!

Looks like the fronts take two bearings no. 6203 RS
and the rears take two bearings no. 6304 RS. Would
think that the spacers would be same as a stock rim, if they use these same bearings.

Thanks Larry, didi you get those numbers off the bearings on your wheels?

Yes from my Lester wheels. According to buykawasaki.com, these same size bearings are used in the stock hubs.

Hi larry,
The plot with mine thickens!
I can not find a part number on the front wheel but on the back one its got a number where the cush drive rubbers go of 25100. From the table I was expecting that number to be 25116! Now I am thrown again as 25100 does not appear on the table at all .
What numbers do yours have on them and do you know where the part number is on the front wheel?
Regards Steve

I worked as a Suzuki mechanic in 77 to 82 and if they were mags they were tubeless... we never (and I mean never) used tubes with mags. When the Lesters came out there were very few tubeless tires... they should be fine. All use a standard size car valve stem.
