I'm liking the velocity stacks, how's the fuelling with them fitted, do they have an internal gauze?

[yozzer74]

Don't no about fuelling yet .but they do have gauze inside them .

[MarkCR750]

Cheers, I might go for a set of those .

[yozzer74]

I got them from dime city cycles in US

[MarkCR750]

Cheers, actually I'm just trying something this afternoon , fitting velocity stacks inside my pod filters (home made) just to see what happens (if anything), but I'll no doubt move to just stacks for appearance sake eventually .

Started making my wiring harness .with the help of Bryan drawing a diagram for me. [ Guests cannot view attachments ] [ Guests cannot view attachments ] [ Guests cannot view attachments ]

Need a little help with my wiring got all lights working starter motor turns engine over but I have no spark wired yellow& blue wires from points to coils then black&white to switch .but there's no spark any ideas what to look for .Cheers

You should have a constant 12v supply to the coils with ignition switched on and the coils earthed through the points only when they are closed.

When you rotate the crank, the wires through the points should lose continuity to earth as the points open. If not, then you'd suspect the insulator washers where the wires and condensers connect to the points as if they are assembled wrongly the wire tracks to earth before it even gets to the contact face to be switched by the points.

I'm getting 12 volts to coils  when ignition is on and I haven't touched the points as the bike was running before I stripped it .Will check tomorrow

[K2-K6]

Easy way to check the points is disconnect the blue\yellow wires and open the points then put a piece of card in the gap, then continuity check down each wire to the points across to earth and you should have no continuity. Pull the card out and continuity should be there with the points closed.

[yozzer74]

Thanks I will give it a try

[yozzer74]

I've disconnected the blue and yellow wire from the points put card in between points now how do I test for continuity

[K2-K6]

Have you got a volt meter that beeps when you connect the two probes together?

I so you put one probe onto one of the wires to the points and the other on onto the points mounting plate and you should have no connection\beep.

The status you are looking for with the card in place is for no electrical connect through the points to earth, if it tracks through then you are looking at a fault somewhere in that system you've checked.

[yozzer74]

Yeah I have one I will go out and give it a try cheers

[yozzer74]

Ok so I've done that test I don't get a beep at all with card in or out when I touch the back plate only time I get a beep is when I touch number 2&3 points
