Hello from San Francisco California USA

Whats going on guys, Just saying hi from the other side of the pond.

Here is one of my minis by the city i live in.

hello ! welcome here !

nice mini with a lot of very nice parts !!!

give some details about your mini !!!

hi
welcome here dude, nice bike indeed, I bet there are not many minibikes like this one in SF
cheers

Hello Honda50,
welcome here
SF is a very nice city, i got some pictures with the same "point de vue" but not with the same bike
see u

hi and welcome here.

hi
I think it's the golden gate bridge, there's a red stuff, didn't know you put it in the middle of the town though
cheers

Well its a 1988 ZB50 with a 124 +R takegawa motor, Daytona 4 plate dry clutch, super cooler, NSR front end on G Craft triples, Takegawa bars, PWK28 Carb, Satiyama fender, Agras sliders, Brakeing USA wave rotors, Brembo Brakes, Ohlins rear shock, Monkey R seat, Ducati mini rear cowl, G Craft underbraced swingarm with a few options, Custom Catch system that a friend made, Also low run production side cover and rear sprocket(Also made by a friend). The Wheels are from a NSR, and the side stand and rear sets are also by G Craft.

Here are some more updated pictures of the bike.

True, there really only a handful of street legal minis out here.

Actually that picture is taken from twin peaks.

hi
is it easier for you to find the parts? it talkes from 5 days to 2 months to get imported japanese parts here, I think it's faster for you
cheers

I have a friend who I run a small business (not our day jobs) with bringing in parts for minis from Japan. The market for these after market items is very small here in the USA, just a handful of guys really who are into it. Timing differs for us too, on average though i say its about a month to receive things. Some items take longer cause some shops are slow.

here is another one of my projects. It started is a Jinching panda, and all thats left of the original bike at this point is the frame.

the motor is a 137cc Honda Nice motor with some parts from TJR in Germany.

hi
very nice pic, I didn't know nice engines were available in the states
cheers

Hello,
Nice minibikes, i like the carbon yoshimura exhaust!!
Not CT70 for your futur project

I do have a CT70 frame hanging up and some really cool plans but i have two other projects to finish first.

My current project that im working on is a 1969 Z50A k1 US model (hardtail). Im in the process of making Carbon fenders and a carbon tank for it. Ive posted about it on other forums. I'm not sure weather to just copy the links or repost the thread on here.

For now here are some of the links to my postings about it.

My other project thats on the back burner and will start once I'm done with the hardtail is a 1972 CF70 (Chaly). I'm pretty sure I'm going to really enjoy building this one up as they are seriously rear here in the states. They were never sold in North America and im not even sure how it got here. I pretty much stumbled on to it by chance.

welcome here and very beautiful pbr.

Its not a pbr, its a 1988 Honda ZB50.

hi
carbon fiber parts are pretty difficult to make for non professionals, the molding process is more complicated than ordinary fiberglass stuff
you need owens with constant temp, vacuum pumps etc...
I worked there for 7 years, well I should say I lost 7 years working there, it's a corsican co specialized in composite parts for aircraft
http://www.cca.fr/
I've planned to make simples parts too, I gotta ask this to one of my relatives who owns all the stuff to make them
there's also an important problem in europe, it's actually THE MAIN problem, it's possible to make all the hi-tech parts you want here, carbon, titanium etc... but ppl are too poor to afford them therefore it's completely uninteresting to make molds and stuff for parts that will be impossible to sell
cheers

I find it to be a very common miss conception that baking a piece of carbon layup is needed in all carbon fiber, not all resins need to be baked to setup. True that most of the aerospace and many other high strength applications use varying high temp resins with prepraig cuts. But for 80% of any moto related applications that process is completely unneeded. WestSystems resins do just fine in normal temps.

I do use vaccum bagging in a lot of cases to lighten the piece as well as ensure zero lifting in complex shaped pieces. But even that is not necessary, It all depends on what you are trying to accomplish. Keep in mind this is all just a hobby for me, I have no intention on selling anything, so its not being made in any sort of high level production process.

hi
the quality or the resin is very important, I think it's safer to use phenolic one even if you'll have to put the parts in a owen to mold them
let me know about your carbon fiber fuel tank, I would use mixed kevlar/carbon fiber though to increase resistance against shocks
how many parts do you use to build your tank? I can see the bottom on the pic, I guess there's a top and a bottom just like the stock steel tank
cheers

Well with the recent monkey tank we just made the top for thats pretty much what we did. We knew we were going to paint the top of the tank and other areas of the tank so we didn't mind what it looked like in those areas. We ended up using a combination of glass carbon and kevlar. the tank was at the minimum 5 layers, and up to 7 in some other areas.



im laying up my hardtail tank today and plan to do a full carbon top with 2 by 2 twil. due to the size and shape im sure it will be strong enough with out the kevlar. If im wrong i can always go back and add the kevlar on the inside once its out of the mold.

hi
have you tested the reaction of the resin with fuel? fuel tanks used in aircrafts are made with kevlar with phenolic resin
cheers

The tank will be coated on the inside with por15, and UV cleared on the outside.
