Setting timing and Haynes manual
« on: September 16, 2020, 05:08:31 PM »
Fitted new points/condensers and ht leads and plugs.
Trying to reset the timing. Haynes says to set the right hand cylinder first and mentions the grey lead. But I've also read somewhere that that's the wrong colour for the right side??
Just double checking before I confuse myself as when I tried to start her up all she did was back fire and wouldnt start.

You can toss the Haynes manual in the nearest bin.

I think that there's a Yamaha manual in the Tech section that you can download.
Yam RD200DX (Gr8auntiepat's)
Yam FZX700 Fazer
Yam RD400 bitsa
Yam RD350B rough
Yam RT2 almost finished
Yam DT360A almost finished
Suzi GT550J just started
Suzi 1250 Bandit regular rider
Yam RD125B (probably!) now being reassembled
Yam AS3 in boxes

I used the tech section advice on the forum for directions.

Used new Yambits points and condensers. Wiped the points contacts down with thinners before installing. Engine ran sweet before I got wiped out recently.

Anyway I used a DTI gauge for TDC and a 'battery & bulb' to work out for the points to open at 2.3mm BTDC.

I can help you sort this if you like. As you know I'm not far from you.

Or I can lend you the kit if you prefer.

if I recall Haynes has the LT points to coil wires reversed. I think they are grey and orange

I might take you up on that. But right now we are all having to isolate for 14 days as my grandsons got possibly covid but we cant get a test

My left points as you look at them has the orange wire and right has the grey wire

Yes... same as mine.

Orange wired points (arrowed in photo) serve the left hand cylinder.

I wasn't aware about timing any particular cylinder first, as it doesn't mention that in the tech data download. I just did the left cylinder first and it worked out ok.

As long as you have the correct set of points to the cylinder youre measuring it doesnt matter

Did your dti guage fit with the engine in the frame? I'm having trouble getting my one in. This is driving my mad.

Yes mine fits ok.

I had an adaptor made that screws into spark plug hole, and an extension probe that screws onto the STU so that it reaches the top of the piston.

This thing just makes no sense to me. I made up a testing bulb. It comes on and stays on for far too long. Looking at the cam on the shaft it seems to me to be completely  in the wrong place. It must be me. Ive never set points timing before. My bikes always had cdi
