So you're going for the A 'stripe' decals rather than the pre-A 'swoosh' ones. Probably a wise choice as the sidepanel/oil-tank decals are available for the A but on the pre-A it was a chromed plastic 125 badge and cannot get them anywhere

 got the tinware back today,really nice finish,fitted new Tap,oil sight glass,and various little odds and sods,

[ffoy]

Excellent. Regarding the oil-glass. It's unlikely you'll be removing/refitting one again but best way to get them out is to push them in then fish them out filler-neck.

Seems a strange approach but they're almost impossible to lever out even if you're not fussed about damaging the seal

[Johnwebley]

thanks for that,

  that is how a removed it,cutting the outer lip off,and pushing through,before taking it for painting,but getting the new one in was hard work !!!,I had to clean some of the new paint away before it would fit,


 thanks for your nice comments

nice sunny day,

  a little pottering in the garage

Is that the same as the RD 200 with the mechanical advance visible outside the generator, If so take a lot of time getting the timing correct with a DTI and a tool to hold the advance open, once watched a boss of mine bump start an RD 200 the put his helmet on to road test it for a fault whilst I kept it running the ride off backwards when he put it in gear as it had started backwards!! Lots of laughs and encouragement on that one.

If you want to email me direct(addy in profile) I will send you a pic of the special tool that will take about 5 mins to make

[Johnwebley]

thanks Bryan,

 the 200 had an advance mech because of the electric start,a sort of Dynastart gadget ,all the others from 100cc up to 400cc used
static timing using a dial gauge,  1.8mm BTDC,or with the new fuel ,suggested 1.7mm

 I have a Dial gauge,like going back to the dark ages with points again -))))))

[Bryanj]

Nowt wrong with points mate, just spend a lot of time getting the gap correct and the timing spot on and you will be fine

Any more progress John?

Any more progress John?

  a little more,

  got the tinware back,

 assembles the exhausts,clocks,electrics,just awaiting a decent throttle cable

[MarkCR750]

Looking good John, it will be great fun to ride, like an FS1E on steroids!

  I used to have a YAS1 twin, a forerunner of the RD,and a YDS7 ,a bigger brother ,before I started owning Hondas

[Johnwebley]

been playing in the garage today,

I have been having issues with the throttle cable,it is one cable from twistgrip to a splitter,then 2 carb and 1 oilpump cable,try as I might
I could not get this to work properly,each time both the carb cables detached inside the splitter unit,

 the splitter outer tube,and nylon inner have some playso I surmizzed the inner was tiltingand the out flexing allowing both cable nipples to pop out !!

so decided to make a new inner unit,using nylon bar,

check the pics,and yes,it works great !!
