    Sure looks good just sitting there.

    Now it needs to be rolled out into the light of day and LIT UP!

    I could not agree more Paul , got her started no problem but the clutch and fuel pipes need sorting but I had a wee spin. Sounds fine apart from the chain guard setting not the best( needs a wee reset ). She won't make the classic show tomorrow, pity but that's life. I was away last week playing commandos at the NOC National rally , auldblue did just shy of 875 mls round trip and was the farthest travelled machine, had a hoot!!

    Mmmmmmh I was wondering why the salesman kept climbing up that rope at the back of the gazebo and coming back down speaking like Burt Munro.

    Anyway , I have some form of electrical issue now. Bad connection to earth intermittent ,the wiring loom does look pretty ropey , to say the least but I was hoping to get a couple of weekend jaunts out the old girl just after the solstise without having to do a great deal more, might just be wishful thinking though.

    Stuck on the new clutch cable, but the route of the old cable seemed wrong.

    [​IMG]

    Goes down the drive side then crosses over, seems wrong. Having a look at the carbs as well float needles are Viton tipped by the look of things but the slides don't seem to be balanced when you look at the screws.

    Why look at the screws?
    With the screws where they are, the slides will either be set at equal heights(when fitted)......or they won't in which case they need readjusting.

    I agree but the difference in the stop screws seemed a lot, when I stuck the carbs back on DS slide gap was big but the TS gap was like the Grand Canyon . Has anyone got any experience with morgo rotary oil pumps?

    Balls up , stripped on of the carb bowl screws. Swap carb Fromm other bike till heli coil gets here or fit new carbs. Would like to fit new carbs but want to fix the old ones and see if it runs ok first.

    Balanced the carbs but the DS carb would not tickle , float and height seemed OK. When I started it the TS was cool but the DS was hot and noisier so on rebuild stripped the screw. What would cause it not to flood the carb ?

    I've used Morgo rotary pumps before, what dya wanna know?

    FWIW I think they're good, they flow much more oil which helps cool the motor somewhat and is useful in highly tuned or stressed engines.

    My 68 is neither tuned or particularly highly stressed, so I don't have one in mine.

    Downsides are, they need bleeding to work properly, an air lock can inhibit their performance. They will make a Triumph wet sump just like a Norton! And on some bikes, the increased flow can cause issues with oil egressing from the oil tank breather.

    Pull the tickler roll pin down, so it reaches the float.

    An M5 will often hold where the original 2BA has stripped.

    The DS carb wouldn't tickle, but apparently, it started and ran on the DS cylinder? :? Can you confirm that's correct? If so, did the TS chime in when the revs were increased which might suggest the TS carb pilot circuit was blocked and perhaps why the throttle stop screw was set so high on the TS carb?


    If the 'float' height is too low the tickler doesn't reach, however, the float needle in your photo appears to be the brass type which can result in a low fuel level. A change to aluminium needles might cure it or the float heights (actually fuel levels) might need adjusting.

    Cheers for the reply les.

    Bike is now blowing the fuse when the ignition is turned on ,I have connected a test light . Removing the, rectifier and zener wires does nothing but taking the brown/white wire off at the ignition switch puts it out.

    [​IMG]

    There is no oil pressure switch connected on this bike, I am going to remedy that today with a bit of luck and the shell seems to be devoid of the brass ground sleeve at the bottom for an earth wire to fit in. I feel de Javu all over again with this.

    Once I get this sorted I can concentrate on getting it running. My photobucket has gone also !

    Assuming the short isn't inside the actual switch, that suggests a short somewhere along the 'white' feed wiring to the coils, brake light switch, etc.



    Sometimes it can be difficult keeping track of which model we are dealing with ('68 or '70). This is the '68 isn't it, in which case it wouldn't normally have an oil pressure switch (and the thread in the '68 timing cover is not the same as the oil pressure switch unless the cover has been changed/modified). The green lamp in the shell was an 'ignition on' warning before the introduction of the oil pressure switch (for '69). Red was for high beam.


    It doesn't need the shell earth/ground, as the 'earth' (return) to the battery is through the red (positive) harness wiring.
    The headlamp shell connection was put there on later models so the front indicators (where fitted) had an earth connection to the red return wiring. It's not a headlamp bulb earth as is often thought (that's what the red wiring is for!).

    Re: Last train to Glasgow Central..........Last Traaaain....

    Cheers Les, the wires at the switch had been "modified" by the PO and the White/brown was melted at the light toggle switch and one of the brown/white wires to the ammeter also showed signs of heat and a show of copper.
    As I have now broken the ammeter cover(bit of glue should be ok) it has now stopped blowing the fuse but as yet I have not refitted it. But I intend to make further investigations when actually replacing the duff wires.

    As for the OPS spoke to a supplier yesterday and he sent me two depending which cover was fitted , one a taper fit. When I withdrew the blanking plug there was alloy trapped in the thread , not a lot , but enough to know bad things will happen. I then fitted the taper thread OPS by hand and then a bit farther with a 7/8 spanner tightening it only with my pinkey as I fully expect it to strip the threads, it in, that's poor when it's wrong threads or worse still not required.

    Mystery of the shell solved for future reference.

    TT thanks for the link, who knows what I am going to bugger up next, i don't appear to have caused any damage to the cover so it my well be okay.

    Thanks again Les , I looked at 68 tr6 / Bonnie on Tuesday and it had an OPS but I'll know the next time, when I get this lot sorted I will get back to the carbs I have changed the damaged carb body and fitted a stay up float and an ally needle, I will also give both pilot jets a probe and see what occurs.

    Thanks again gentlemen, I'm going back out to see how many step back I'm going to take this evening.

    As far as I know, "pre-oil pressure light" timing covers are tapped 3/8" Cycle. Not tapered.

    Nobody makes pressure switches to fit that. Some switches could be turned down and threaded to fit. A Cycle male to NPT female adaptor could also be made.

    Re: Last train to Glasgow Central..........Last Traaaain....

    That's correct (as it was intended to be a connection for a test gauge, so normally fitted with a 3/8 - 26 blanking plug).


    BSA/Triumph twins and triples didn't have 1/8" BSP pressure switches !!!!!!! :? :roll:
    Edit: Early oil pressure switches were 1/8" NPT. Later they were NPS (I don't know where they get 'APP' from?)

    Re: Last train to Glasgow Central..........Last Traaaain....

    The gauge I have fitted is 60-2133 tapered thread, it has an o ring at the base but as it is a fairly tight fit I will leave it till I run the bike and deal with it when (if) it leaks.

    The other OPS was 60-3719 again by LS Harris marked on invoice as Veglia is the one for later timing covers apparently.

    I have disconected the OPS anyway and all electrics seem to be working however I still have to cut out the damaged wires and replace them. It would have been easier to replace the entire loom and anciliaeys, podtronics and EI at this stage but that's no fun. It probably turn out to be sheer folly but hey ho.

    Helicoiled the carb with 2BA seems ok but who knows unless you put fuel through it and use it.
