Bucket rules (or lack, thereof)?

[gatch]

So there is a few smalls things left to do. Still need to run engine in and figure out some jetting etc, but with finishing work late, I'll be left with friday only..

Make a few tiny spacers, drill out a seized screw, bleed brakes (again), the front brake is still spongy as hell, can't do the back till I get a reservoir sorted.

Replace a few nuts with nylocs, wire in kill switch. etc etc.

Still need to bribe someone for some transport.. hint hint

Soo where there used to be spark now there is none.

I am at total loss as to why, connectors are tight, though I'll have another look tomorrow. It is well earthed. Essentially nothing has changed since I had the motor running, except the spark has vanished like a fart in the wind.

Cock of a thing.

but on the plus side, your electrical system as about 4 things, can't be too hard to fix and maybe the same problem stopped it uning good before

Got it to go now. The issue I currently have is I'm not able to make it rev past about 3.5-4k. It just bogs and backfires like fuck, bigger/smaller jet seems to have no effect, advanced and retarded points a few deg and no change, changed needle heights, no change.

Something is fundamentally wrong here.

[Yow Ling]

the fundamental problem is its not a FXR, which never act up like your engine

Old fuel, blockages in the carb, screwed plug. All things I would look at.

New fuel, new plug, new carb..

Still scratching my head.

My money is on an ignition electrical fault that breaks down under load, ( like 4-5k rpm & part throttle).

First bet, Points Capacitor.

Next check the kill switch and wire for a partial short, or a switch where the button spring bounces with vibration and intermitantly kills the spark, happened on TZ's.

Then if thats not it, try running it at night and in the garage where its realy dark and look for a spark jumping somewhere. Have a friend help look too.

It could be breaking down inside the coil or stator. Thats not so easy to see but if you have a small transistor radio handy, you can hear the hidden spark clicking on the radio.

If the points cam does not have a small piece of oil soaked felt rubbing on it then the cam needs a very light smear of grease or the heal of the points will wear down quickly and close the points gap, might be why you saw dust inside the points cover.

I have also had problems in the past with the little insulating washers that fasten the coil wire to the points breaking down and there is the traditional problem with the points capacitor packing up, try replacing it, there is no majic about them, a car one will do or radio noise suppressor might work. A new points capacitor can be fitted at the points or the points side of the coil.

If none of that works, it could be a broken wire, if thats the case the break will most likely be near a lug, try pulling the ends of the wires and see if anything comes apart.

[koba]

could just be a bad earth on the coil too...

The condenser breaking down sounds quite plausible, on further discussion with the motorcycling mcgyver, he thinks so too. This is now this weekends mission.

I have made triple sure everything is earthed to everything else. My arm earthed to nose, nuts to leg, etc etc.

[gatch]

Also, this is how it looks right now.



Pipe is too loud.. Need to make silencer. Sounds like an Iroquois helicopter flying right over head as it is..

[gatch]

So.

Saturday afternoon my motorcycle Mcgyver friend Chris had a go at my GL/spada. Turns out, there was more to the timing than meets the eye. The little lobe on the end of the cam was worn and not sitting properly in the slot on the back of the points cam/rotor. So every time I attempted to start the bike, the cam would move a little and the points wouldn't.

With judicious use of a file and some emery/wet and dry, we cleaned up the scarred surfaces and reassembled. Tried to start it.

Voila. Brum brum.

Starts fairly easy every time. This makes me very very very happy. I am glad that it was not a major mechanical issue and that it was a relatively simple fix. The negative side is now I have a whole raft of minor issues to look at. It is running far too lean with loud open pipe. Even with a much bigger jet over standard. So a silencer is a must. Then get the stock carb back on and have a go at jetting it. Then there is the suspension to tune and brakes to uprate..

But it runs

Hi Gatch, great work, glad to hear its now a runner.

[F5 Dave]

caliper clean up & some new pads. Those Honda era brakes are really good.

& yes a silencer is required or we'll get kicked off tracks.

I ground the disc flat a while back, new pads will be a cinch, getting a hydraulic line made.. Going to try make a silencer out of some ally pipe, I'll turn up some caps for the ends, get some perf tube or roll some heavy mesh for a core and smash some steel wool in there.

Any better ideas ? (that involves minimal transfer of legal tender)
