Rotary Valve/disc Position ?

[taff4]

Just building our motor back up and wish to confirm the disc position at TDC.

Any pictures or sketches or a description available, please ?

Many thanks.

Thanks, I have seen that before and was confused that the leading edge of the disc was positioned at the start of the inlet aperture and not opposite the timing mark indicated ?

What's all that about - am I missing something ?

Ignore the timing mark , the diagram was downloaded from the SWM dealer manual and also showed the settings for all the MX and enduro versions...so I tidied it up just to show the trials setting.

OK, many thanks for the clarification.

We can now complete the bottom end and make some progress !
