I have spark, both plugs spark at same time when I kick over!I have yet another question on how to set timing(I look at Yamaha TX500 service manual)! I don't see any marks on this and it says remove hex plug? on left side to turn engine to align marks!
Hmmm. Picture above clearly shows two sets of points though?Both plugs will fire every stroke in a wasted spark system. This allows for the use of one set of points or electric trigger to run both cylinders.
I believe the XS500 has a 180 degree crank. Therefore, two sets of points would be required.Hmmm. Picture above clearly shows two sets of points though?
I see. Makes perfect sense then, I agree.I believe the XS500 has a 180 degree crank. Therefore, two sets of points would be required.
Correct.I believe the XS500 has a 180 degree crank. Therefore, two sets of points would be required.
Are you absolutely sure? The sparks left and right should be 180 degrees of crank rotation apart. You can see the two sets of points are 180 degrees apart in the picture.I have spark, both plugs spark at same time when I kick over!
No. Every other TDC event.Will fire each upward stroke on each
Not on a system with two sets of crankshaft triggered points. Each and every stroke towards TDC on each cylinder (like a two stroke engine). Hence, known as a wasted spark system on a four stroke engine.No. Every other TDC event.
I assumed cam triggered. I should not assume.Not on a system with two sets of crankshaft triggered points. Each and every stroke towards TDC on each cylinder (like a two stroke engine). Hence, known as a wasted spark system on a four stroke engine.
It's not driven directly from the crank. there's a shaft and gear that reduces it to 2 to 1.... so it's timed just like a camshaft driven system.Not on a system with two sets of crankshaft triggered points.

Thanks for vindicating me!It's not driven directly from the crank. there's a shaft and gear that reduces it to 2 to 1.... so it's timed just like a camshaft driven system.

Thanks for that. I would never have guessed looking at the picture posted above.It's not driven directly from the crank. there's a shaft and gear that reduces it to 2 to 1.... so it's timed just like a camshaft driven system.

Yes, you're right.Thanks for vindicating me!
