Re: CG125 Decaff + goodies

Hey Glenn, dunno how respectable I'll get it, but hopefully things will look more coherent.
Settling in a bit now and getting my bearings. I can find my way home now without getting lost!
It's much warmer and dryer here, so I use the bike alot.
It's so freaking economical even if I cane it.
I've still not fitted the race CDI unit yet, will give it a whirl after I've replaced the stator and flywheel.
 
Re: CG125 Decaff + goodies

It looks a like this Glenn, bit of a change from the mountains.

Sprayed the exhaust up today.

P1030655.jpg


And put on the new bars, levers and 1/4 turn throttle. Transformed the ride again, for the better.

Then I thought I'd plug in the race CDI to see if it helped the engine respond to the faster slide opening ...........

HOLY MOLEY! :0 What a difference :)
Crack open the throttle and the exhaust barks like an angry terrier.
A little blip will lift the front wheel very easily.
 
Re: CG125 Decaff + goodies

I've got hold of an imported '74 US CB125S frame for a song. Under $50 posted :) I was trying to get a pre '73 frame (UK road tax exempt) but nothing was coming up that wouldn't have taken 10 years to break even as the shipping was extortionate. I'd looked at SL/TL and CL/XL frames but decided to stay with the lighter CB/CG variant. They've all got the same geometry. For a 37 year old frame the finish is great, the build quality is leagues above my chinese frame, the rear triangle is made out of good tubing as opposed to round metal. Having cleaned it up a little this evening it doesn't really even need to be re finished.

Compare it to the 2005 Shenda frame:

P1030172.jpg


The rear triangle is COMPLETELY attached to the main frame, it's about 2" further forward and the gusseted frame plates are done properly.

P1030688.jpg


It's good and straight too.

P1030687.jpg


So that's the winter project for this year ........ swap everything over and keep on tidying it up.
 
Re: CG125 Decaff + goodies

I've been cleaning off the frame and it's actually in very good condition, a few little scratches but the finish is sound, no rust, and there are no lugs that need to be chopped off. So blasting it and powder coating seems a little unnecessary now.
The next dilemma is whether to register the frame as a replacement frame for the current bike, keeping the same crap identity and 2005 registration. Or I could register the frame as a 1974 Honda and get a new identity for the bike and an age related registration plate. :)
I've got hold of some old 14" Betor trials shocks that will give the same ride height on the standard mounts that I have modified the current frame to give.
I just need to take them apart and find seals to rebuild them.
 
Re: CG125 Decaff + goodies

Bloody Betor shocks turned out to be scrap, got ripped off and struggling to get my money back :(

Snapped another Kickstart so got an xl type one which should be a stronger level although I have to shorten the brake pedal pad for clearance. Put on a k&n type filter which has cleaned the pick up from tick over to 1/4 throttle.

Was in the area so I went to the Sammy Miller Trials shop and treated myself to some pre '65 bars.
Saw these little puppies:

I've got my workspace sorted at last, and spend a very chilled hour this evening listening to 80's radio and degunking the new frame.

P1030749.jpg


Went to see the sidecar motocross the other day, some pretty interesting engineering going on. Bespoke north European engines.

P1030701.jpg


And my forks have started to sag a bit now, I think the chinese springs are losing their mojo. I've dropped the gearing back down to 14/45 which is a 3.21:1 final drive ratio, and still gives me enough zip along the little stretch of main road I use, but a more fun granny gear first. Really I'd like to try 15/60 which would give a 4:1 and have a box so low that I can race tortoises. :)

I'm slowly amassing all the bits needed to do the lighting in one hit. I gave it an oil change and engine flush at the weekend, got it damn hot and drained a whole heap of crap out of it. Probably the first flush it's had in its 28000 mile life. Just keeps on starting up and putting away. Love it :)
 
Re: CG125 Decaff + goodies

Erksine, I don't know if I told you before (but I probably have)- my old 175 had all sorts of issues clearing the kicker lever. So I mounted it pointing forward and slightly down (to clear the oil filter cover). Just had to start it by hand.

Coming along rather nicely good sir!

Having drilled out datum holes I shall mostly be shaping the plates with the aid of a spoon, some adult bonjela, a cassette of This Mortal Coil with an inspitrational post card of some 17th century marble buttocks from the Three Graces (Antonio Canova 1757-1822)




bahahahah> Cant blv no one commented on this man.
Hillaroius.
Great build. way to revive the un knowns!
 
Re: CG125 Decaff + goodies

That Ariel is probably most famous trials bike ever (GOV132)
Great picsof bikes, not sure what to say about the one above? (Bonjela for teeth, cassette tape and making an ass of yourself?)
Bite me? ;D
 
Re: CG125 Decaff + goodies

Hey PJ

I've just researched GOV 132, I hadn't realised it was so famous! I just thought it was good looking.

Seems like an age ago that I was doing the rearset plates, lots of water under the bridge since then!

Thanks Rich!
I think if I tried to start this by hand and it kicked back I'd have a broken arm!
 
Re: CG125 Decaf - running on one (vid)

So here is my first attempt at using video mode on my camera and uploading, which is the real achievement rather than having actually done anything new to the bike yet.

 
Re: CG125 Decaf - running on one (vid)

Having moved I'm now having great problems sourcing stuff and services like just getting some sheet ally for side panels on the new frame and somewhere with a guillotine.
I can't even find a second hand skate deck to make another seat out of, and I'm dammed if I'm going to buy a brand new board to massacre.

Met a guy today selling a ratty CG for $450. One of the last ones Honda made in Japan before they licensed it out to Brazil and all the cost cutting started. A little gem project but I had to get real and walk away. Sooo tempting. These were the highest quality CG's made and the engine only had 20k on it :(
 
Re: CG125 Decaf - running on one (vid)

If your using the Honda frame you have to go through MOT and all the other rigmarole.
If you do happen to get 'pulled' and cop wants to be an ass (don't they all? ::) )
If they check numbers, you could get done for fraud (serious shit)
I know there's a bunch of 'If's' but, you should be aware of it

Hey Pj!
How are you recovering? I haven't decided whether it will be just a frame replacement and keep the same V5 identity or whether it will become a '74 Honda import, either way I'll keep it legit, It will depend on where the $ is when I swap everything over. I've no need to fall foul of the feds. One way will cost nothing, the other will cost a$80 registration fee, $40 i.d. fee from Honda and the price of a new MOT so we're looking at about $150 all told.
 
Re: CG125 Decaf - running on one (vid)

Started throwing bits on to the new frame.
Got hold of a better rear mudguard and had some ally side panels chopped out.
And scored a skateboard too.

Re: CG125 Decaf - still potching about.

Quick update.......

I cut and welded the ends of the seat rails up at an angle to raise the rear mudguard.

P1030841.jpg


Scored a XL 125s front end with very good pair of Showa forks for a song :)

P1030858.jpg


Cut the skate deck to shape for the new seat and raised the front profile to leave room for the tank tab underneath.

Once this evolution is done I'm going to be left with 75% of a rolling cafe chassis. Hmm
I can feel another bash at a cafe coming on!
 
Re: CG125 Decaf - still potching about.

I scored a good period back wheel from evilbay for $15 and collected it yesterday.
Now I'm only a swinging arm short of having a rolling chassis cafe project to work on when this trials bike is completed.
Locked myself in the garage with some Plan B tuneage and a few bottles of Glenns favorite while I cleaned up the rim.
