Electrical / Re: static timing/points adjustment
« Last post by The gizmo on May 20, 2019, 01:55:53 PM »
so I figured out what my misunderstanding was...I was caught up on the fact the red and white wire off the switching unit had a male/female jumper lead off the end of it. but that's just power in to the box. so that had to be spliced in with the ignition feed to the rest of the bike....kit is all set up. statically timed. lights on box go off as each cylinder reaches firing marks. now, however, I have spark at each spark plug. but the spark is very weak...now to figure that out....

Its the terminology that can get you drifting away from understanding what is going on  ;)  You are not hooking the red/white up to either coil- you are merely using the same ignition live feed to the coils- they are both fed from this common feed and the ignition circuit only seperates after the coils- the orange and grey circuits.  So yes- you can use the Newtronics male/female sub harnes to splice into either coil feed.

Yeah the light on the unit turns off as  each cylinder reaches its firing mark. I'm not by any means an electrically inclined person so I need very basic terminology for it lol. I understand how the plates and sensors work together my only issue right now is just the red and white wire. So that can be hooked up to just one coil? It doesnt need to be hooked to both? Does it matter which coil its connected to?

You mean you have it statically timed so that each LED goes off at the correct mark for EACH cylinder firing mark?  Remember you effectively have 2 separate ignition systems on these engines, firing at different times 180 crankshaft degrees apart.  This is 90 degrees apart on the camshaft and timing plate- hence the 90 degree offset for each points set and now the Newtronics sensors.  If you understand the theory and how it should work- it is easier to install and troubleshoot- points or Newtronics.

The red/white is the power feed to the Newtronics box only- it can be connected to either coil feed or indeed any ignition live cable.  The Newtronics box then imitates the action of the points by grounding or interrupting the coils return path to frame through either the orange or grey wire (left and right coil return), via its blue lead with tag.

One caveat with the Newtronics which is otherwise an excellent system- even more so you need to take care not to leave the ignition switched on and engine stopped- you will cook the coils.....

Well I scrapped the idea of using the points and got the newtronics kit from yam bits. I have it 99% hooked up. Its statically times and light goes off right at firing mark. However I'm a little stumped with the red/white wire going to the coils. There's a red/white wire lead off the newtronics box that has a jumper at the end. One end has a Male plug in and the other is female. Each coil has one Male and one female from it. Do I plug each red/white lead from the box to one coil? Or Male to one coil and female to the other?  I guess I'm just not understanding the diagram correctly...

Fuel System / Re: Pod friendly carb replacement for BS38s ?

Maybe worth looking into this setup too. I emailed them asking would this kit work with a xs500c and they said to make a note that itís a 500 when ordering and they will jet them accordingly. So could be a good straight swap for those wanting to ditch the stock carb and airbox setup... probably still some tuning and maybe jet change required but pretty much all there.

🤔 hmmm... good to know. What other front end swaps have people done out there? Wanting to try something but would like to see some real world examples and all the difficulties encountered... I imagine opens up a whole new world for modern calipers too...

Digging up this old thread... very keen on doing this conversion and would love more details and feedback on how it rides! More pictures and a how to would be fantastic!
