Checking ignition timing on moped engine.

Short video of me checking the ignition timing on my Yamaha FS1E moped using a Strobe.
(This video was made to show how I check the ignition timing on my mopeds and other small bikes using a strobe. Due to a valid comment about the stator being fixed and therefore the timing being fixed as long as the points gap is correct and the heal not worn, I have changed the title of the video. I believe that this is still a valid video for other engines as adjustment of the ignition timing is done when the stator plate is turned using the slots that are in many stator plates. The contact breaker points must be in good condition though and the gap set correctly before adjusting the plate. Hope this makes sense, Bye for now! )

Very good Mr Mike well done

Neat idea with the old spark plug 👍

10:32 Its called the dwell angle...

I loved them but couldn't afford one fs1e and ss1e and Suzuki ap 50 and honda ss50 I had a Puch moped I cannot believe how much they sell for now it's rediculous

The timing is fixed on them anyway. You can only adjust the points gap. All that faffing about for nothing.

[@johnjones4825]

Agree about the faffing! Changing the gap changes the timing. Of course, the FS1( and EVERY other bike I worked on back then) sold in South Africa had the top dead and fire positions stamped into the flywheel. Simple: a spot of white paint on the mark and pointer, run the engine to check with a light, adjust the gap as needed.

Hi, chaps, thanks for your comments. I get what you mean about the timing being fixed. I guess I chose the wrong bike to demonstrate how I check the timing on my mopeds and other small engines. I should have show it on an engine that has an adjustable stator plate. I will change the title of the video if I can. Bikes like the NSU Quickly with slots in the stator plate were set up in the factory with the correct points gap and timing, then the stator plate was marked with a line stamped from the plate to the crankcase. You could then fit new points, set the gap and as long as the line was in the same place the timing was correct. The problem is that years later when people (like me!) are building up engines with parts from other engines the lines are not necessarily in the correct place.

Very nears really why do incompetent idiots think it's ok to tell people how to service fairly valuable equipment
