Today's Job!

[GT750Battleship]

Hi,about to play with the damm points again this morning.....bike was going so well yesterday....then after stopping for coffee it decided to develop a miss,initially thought it was low on fuel,about to go on reserve,checked fuel tap bowl & fuel flow at the tap,all appears good ?
Will clean up the points today & reset gap etc,but I think it's time the points system should be binned in favour of an Accent Electronic System ?
Cheers,
Roger

Check plugs first Roger, I don't want you spending all your hard earned stuff on electrickery while there's still distilleries and brewers that need your support.

[ConnerVT]

Also check the battery voltage.

+1 to what Conner said. The cabs may need looked at too. But, what do I know ? I have poor mechanical skills.

[GT750Battleship]

Thanks all,done on the cheap with emery cloth on the points,all good,fired up first kick,battery a little sad after mucking about using the starter motor in failing light yesterday.
Allan thanks for the advice about not spending the "brass" !
I'd better keep a few bob aside....to buy you a few drinks when you pop in on the World Tour !!!

Cheers,
Roger.

When I bought my 74 750 last year I had the same issue , a misfire would occur after several miles.
I cleaned the points etc and it ran perfect until 10 miles out then the misfire started again. I replaced the condenser,same result. Replace with a spare point and problem solved..about 2 months later I installed an Accent Iggy.

The new point solved your problem, even though you had plenty of thickness left to them ? If so, how would you know which particular point was causing the problem ? Unless, you replaced all of them ?

[Alan H]

The problem with cleaning points with emery is that the coating is rubbed off and they wear even faster. They can be cleaned with a piece of card pulled between the points, but if they are rough, or have a 'tit' on one side, then they are fit only for the bin. Yes, electronic ignition is lovely etc. but a set of points works just fine when looked after - much like the rest of the bike really.

[GT750Battleship]

Absolutely Alan,I tried the card trick first,they didn't respond! Hence plan B !!! I'd do a proper job on them if I had time this week, take them off completely & order a new set ? Will do this next week !
Cheers
Roger.

It was the left side that would develop the misfire.

Roger,

Throw those stupid points out and fit something a little closer to the current century. Kettering designed that system back in about 1910 and it was great invention for the time, but that time has passed. Every GT750 I build I think I'll use points and each time I get there, I throw them back in a box and fit something that doesn't wear out or drift out of spec.

So far I have fitted 2 sets of home brewed DYNA triples and Newtronics. DYNA has a much fatter spark, but next time I'll try Accent I think.

[GT750Battleship]

Thanks TZ,that's what I think I'll now do,go with the Accent System,supposed to be very good!

Cheers,
Roger.

Oh come on tz, where's your sense of adventure!!!
Fit points and show them that you are the master.
This technolology crap will never catch on you know!!!

GT points are close to this century - they're only 30(ish) years into the last one - I remember it well!!

[pearljam724]

In regard to an electronic ignition plate. Once installed, do you have to reset the timing ? Considering the bike was in time before you install it.

[Suzsmokeyallan]

I've got a Newtronics kit and an Accent kit and I like the fact I can keep the three sets of points on my stock A model Buffalo, AND they give me no trouble.
This summer I'll install a new wiring harness I made for the three points wires to replace the old original hard ones on the bike now.
Yes I know all the virtues of the electronic ignition systems but I like the points on at least this bike,,,,, just because.
Most people get confused when they see the three sets of everything in there with the cover off, and for most modern mechanics they just cant wrap their head around the whole thing and how to go about attempting to adjust it

Ian, did you remove the electrical panel to check the points wires and alternator phase wires behind it??? I had a misfire on the left cylinder that I eventually traced to badly routed wires from a PO with compromised insulation rubbing on the metal inner fender and partially earthing to the fender at times.


Just general checking of components and relubing the felt while on a road tour through BC in 08. Consider these times a sort of "therapy" or a points Zen moment.
