Thought I would send a picture of my just finished bike. It started as a 1973 Z50. I got a set of MR50 forks off ebay for $45 and made my own triple clamps, bar risers, kick stand and brake pedal, all out of billet. The emblem on the tank is from a 1970-71 Z50. The rims are 10 inch and the swing arm is extended 4 inches. I am still waiting for a Kitaco 4 inch over swingarm from classic honda but they are very slow. The motor, which I built myself has a Trailbikes 88cc Big bore/race head and manual clutch and the original 1973 bottom end, high volume oil pump ect. the exhaust and tail section are also from classic honda as well as the shift pedal. The exhaust's baffle is very restrictive so I had to pull it and add a little extra flow. The paint is house of color blue flake over black which my father-in-law did for free. Just thought I would add my bike to your awsome website! thanks, Barry.

Hi again Jeff. You already have my bike on your Z page, but I thought people might be interested in this. It's no fun parking it in the winter, so I thought studding it might be the way to go. The proper way is to stud from the inside out (yes, it sucks and you WILL get bloody hands), but the results are sweeeet. Pavement like traction and being able to wheelie out of corners is pretty cool.  
 
Self tapping 3/4 inch sheet metal screws work just fine for these little bikes. No need to spend the big $ on the ones for snowmobiles. You also MUST install a liner in the tire before mounting for obvious reasons. Use foam pipe insulation cut into 2 inch strips, then glue them into place (3M Spray Adhesive is the best).
 
Buying another set of rims off of ebay is the way to go (got a pair of rims with tires, tubes and hubs for $50). Mount them up as usual, use about 15-17psi of air and away you go, knocking your buddies into the snow banks. Have been using mine for about a month with no problems.

I won't bore you with every nut and bolt, but there is tons of other cool things that the trained eye will pick up on also. Over the winter real oil filled forks will be put on along with a disc brake. Thanks for posting the cool old school Z50's. Every one else seems to have forgotten about them. How could we ever forget about them?

 

Here's my 72 z 50.  Many years under construction it's finally done (yeah right).  Total restoration, custom paint, lots of polished aluminium, new button head SS fasteners, chrome, motor by Jeff at Mini Gunz:  88cc, race head and cam, oil pump, 4 speed, manual clutch, carb, and pipe.  It ripps!   Thanks Jeff Tuttobene at mini gunz.  Quality work, reasonable price.

 Wow, a Z50 chopper, what next?

MiniGunz has been there from the beginning. Check them out here.

Some new Z50 action from France... Sorry about the no helmet clause. They will learn the hard way.

These are some pics of my 1999 Z50R.  Its completely tricked out with nearly $2500 in it.  It is the best stunt bike and is street legal in Illinois.  Can you please put these pics on your Z50 page?

Thanks

Cool Z50 website at www.minigunz.com ,and another at Trailbikes.com

The shredder tires are available at any motorcycle dealer that has a Parts Unlimited ATV catalog {cheaper and no freight} !! The best tire that we have found is used on snowthrowers, it is called the Snow Hog.  You can get the tire at small engine repair shops, just have them look in their  tire books. The Snow Hogs should be available for about 30.00 each.

Hello 
you said that these snowthrower tires would cost about $30 a piece- thats way to much to be paying i have the same tire for much cheaper. $18 per tire for z50 tires.

Here is entry one, picture one. One very trick, one very bad ass Z

This powder keg belongs to Lewis Towells. Maybe a John Dowd replica, #16

I asked Lewis to give me the history, very interesting. email Lewis at lewis.towells1@orange.net if you have questions for him.

Ok, here goes,

The bike started out as a 1980 Honda z50r, I bought it 5 years ago at a garage sale for around $90, the bike was a wreck and didn't run. Ever since
then its been an on going project. I totally stripped the bike and wanted to rebuild it as a 88-97 model, being a fabricator/machinist I had to weld a few more brackets on the frame and move some etc to allow for the different tank seat etc, after that was done I sent the frame, forks and swing arm off for powder coating, totally stripped the engine and completely rebuilt it with new, including a 88cc kit with full manual clutch, basically every part in the engine I bought new. I pretty much threw everything else away!
When I got the frame back I assembled the fork assembly which is all new apart from the top outer part and swing arm with all new bearings etc. Then came the wheels, I bought some kitaco anodised black rims and new hubs which were painted gold, complete with new tubes and aftermarket chunkier tyres.
Then went on some heavy duty rear shocks and a fast 50's bar/clamp and throttle kit to give me a rolling chassis. Then on went the new tank, rear cowling and seat (all new of course!) Along with the front mudgaurd and number plate.
Then came the good part, mounting the engine into the frame, (88cc, 18mm carb, high performance cam, oil pump, 4 speed gearbox (1 down, 3 up), full manual clutch). Then the bike was basically finished! EVERY SINGLE nut and bolt is brand new on the bike. It also has many trick parts such as tappet cover breather pipe, fast 50s pipe, cam cover, billet head cover, skid plate, honda gripper seat cover, xr50 fork gaurds, Honda cr250 feet pegs, uni filter, the list goes on and is never going to end!! The whole bike is new except the engine case, frame, swingarm and top part of the forks, this bike is faultless, I must have about $6000 invested into this bike! It is also very quick, quicker than most 90cc xr50s!
Future things to happen on this bike include a box section ally swing arm mono-shock conversion along with some Sano bombshells!!

Wow, incredible!!
