I have new coils plugs leads new ignitech sparker unit i have checked all wiring earth's every thing I am suspecting pick up coils although they check out with resistance etc they are 30 years old
The symptoms are weak intermittent sparks it will run for a short time then nothing
So my question is pick up replacement I don't really want to get second hand ones as they will be 30 years old as well so what options are there for new pulse coils

hallo Tritonkev,
have a look at this link:

https://www.ebay.com/sch/i.html?_nkw=42X-81670-20+yamaha&_sacat=0&_from=R40&_trksid=m570.l1313

it looks like brand new, no warrenty from my side whether it is OEM or chinese.

cheers Anja

OEM parts are even 45 years old but there are still many around that are working well. Those people who modified, renewed or "optimized" the electric stuff on their bike the most, have the most problems on the TR1 meetings.

Btw. it would be nice if you could use the dot, comma and shift keys of your keyboard now and then. Your postings are hard to read...

Thanks i tried your link but they won't ship to the UK
