The rebirth of Lazarus

[mickwinf]

I seem to have sorted the charging issue, nothing wrong with the major components but on going through the wiring I did find a couple of loose connections. Once redone it now charges up to 13+ volts with revs. One more step forwards. I do have a small oil leak underneath the engine which may come from oil drain plug but difficult to see as the oil runs and drips off sump.will have another ride soon to see if any more snags crop up.

Check gearchange shaft seal

Check gearchange shaft seal

That made me smile Bryan when I filled my 500 with oil after the rebuild I somehow forgot to fit the seal - boy did it leak after a few minutes.

[mickwinf]

all dry under the sprocket cover, all new seals etc.

[Bryanj]

Possible bad drain plug threead, bad washer(alloy) of cracked sump pan, you need to clean off totally and find where exactly comming from im afraid

[mickwinf]

Hey Bryan, the sump pan had been repaired before an fitted with a smaller drain plug so might be the culprit.

[Bryanj]

Could be porous weld, same sump 500/550 all way through so should be spares about, i may even have one but cant get into my garage till i fix the door, do have a 550 bottom end in the car i will see if it has a sump.on it for you tonight

[mickwinf]

Dont worry Bryan I have a spare if I need it.

Lazarus is having a difficult birth. Can not get him to run for more than a mile or so before he gives up the ghost. Feels like fuel starvation, tried on main and reserve with same result. Tap has been rebuilt an tank cap is new. Also had a new plug go off so only 3 cyls until I put new plug in although the spark is not great looking when checked against the cylinder head. Coils are not great so might get some new ones as don't feel confident to do the Ash fix. Going to check fuel flow this afternoon and go from there. The only positive thing to come out of breaking down is a couple of people stopped to check I was OK and liked the bike!

[Bryanj]

Have you still got points or is it electronic?

[mickwinf]

Hi Bryan I am on points. Just checked my fuel flow and discovered there is an airlock in tank.when fuel turned on no petrol came out of the tap until I opened the cap. The cap is brand new from silvers but maybe the vent hole is blocked? I have put my old one back to try. Also trying to vac sync my carbs but no 3 not playing ball, adjustment of screw does not seem to have any effect.hope to get a bit of time to experiment over weekend.

I had same problem. Took the cap apart - some kind of seal,had shifted and was blocking vent hole

[mickwinf]

well that went well, not. Left the ignition on overnight, charged up and went for a short ride and going better and kept going until i stopped to investigate a noise ( chain catching on centre stand )  and then would not start. Also clutch slipping very badly. My partner had to come and jump me off ( no tittering at the back!). ho hum more to do, although its the original clutch so probably well past its best.

[Bryanj]

More likely the worm mechanism stif or cable route, i severely abused a 500 clutch for years making it slip at take off but was still in spec and if used normaly worked fine
