my first bike H100A 1980, ratty racer. 2015 build pics (WIP)

[RyanTZR125]

I scored myself a cafe racer seat, took as part payment for some work carried out. I've sat it on for the photo, for fit, not too sure if I should take off the rear mud guard, would mean relocating the rear light.
Also wondering on the hump, spray matt black or leave silver?

All fitted, with the aid of some rubber door stops, bolts and pipe clamps
Next is to find a replacement rear lamp and indicators, the wires are breaking up so will just replace them. I have a pair of rearsets, just not yet worked out the fitting, I'll have some tabs welded to the frame for them at some point, but untill I work out how to make the linkages, they will stay in the spares bin

They usually just turn the existing gear shift lever through 180 degrees to use it with rearsets. Has the added benefit of converting it to "racing change" (1 up, 4 down) at no extra cost.

Rear brake usually just needs you to take a shorter pull-rod direct to the rearset lever. So a bit of bar, threaded at one end and bent over at the other and on a pre 1986 bike, the brake light only needs to come on with one of the brakes.

It would look pretty boss with underslung, rectangular mirrors.

I'd loose the flashers and that whole tail light unit and fit a BSA bantam "wipac" tail light.

EDIT: That IS an expansion chamber exhaust. The double cones are inside it. One of the reasons they do such good wheelies.

The brake side rearset has a bracket for my rear brake switch, I don't have a front brake switch, so handy to know only one will suffice

I'm on the look out for the right morrors, some chrome rectangles would indeed look boss I'm loving the look of that tail light as well I'm torn on losing the flashers, my sensible side says keep them, but I've been riding the past 2 months without them working I'm also wanting to get a single 7"" headlamp and maybe putting a small smoked fly screen.

Bit more fettling today, fitted rubber gaitors, new rectangle bar end mirror, these are on a ratchet arm, so can be under slung new indicators, rear light and number plate, fitted with a homemade bracket.

Nice work, looked pretty hopeless at the start!

[Tim..]

The before and after pics should be good on this project.

I think the rear hump should go gloss black to match the tank. (Or chrome paint to match the front fender maybe)

It's coming along a treat mate! I'd definately go for one colour and contrasting graphics maybe.

KMX125 sidestand?

[RyanTZR125]

[stevo as b4]

Cool! It still needs a spannie though dude!

For somthing different I'd have a matt black chamber with a short slashcut or shotgun pipe over the silencer, so that it just looks like a big bore fat pipe.

How does she run anyway?

[RyanTZR125]

[Nexus Icon]

It's like a different machine.

Great work

were those indicators similar to these?

ebay? about £2.50 a pair? from Hong Kong?
sorry to tell you dude, but they last about 4 weeks before they crack at the point where the head of the indicator meets the stalk.

Worth a go at £74 posted.

The MB80 was an 80cc variant of the H100, sold well across europe. Engines are a direct swap & i'd hazard a guess that if you were creative with some spacers & tweaked it a little then you'd make it fit.

I can recommend the proma pipe.

I have one fitted to my h100 powered MT50, goes like hell in such a light bike. But mine was a proma tall pipe, goes up round the engine trailie style.

That h100 is looking so much cooler than when it started.

Regarding your rearsets,

https://i1175.photobucket.com/albums/r633/tim902/H100001.jpg

That's how the racers over in oz seem to run em on the brake side

https://www.ozbucketracing.com/images/BRA_Riders/70_christopher_law/70_c.law102X646.jpg

And on the gear linkage side - little dogleg on the selector shaft, rose joint onto a rod, rose joint on the pedal end & you're laughing.

What i'm interested in is what the disc front ends are off!

Could be an MB50. They had discs and they are basically the same bike, in fact the h100A is called the MB100 over in Oz land but the H100S is a H100 there. I do like that pipe. I love how expansion chambers work.

As far as I understood the MB50 & 80 had cast wheels?
