points setting

[Biggut]

Earlier this year I got my 1969 ct90 running really well. Set points at .015 and timing with engine running is dead on. Then I read here that .016 is suggested. I would like to know what the advantage is. I'm hoping to hear a little improvement in top end.

I also learned a valuable lesson. Do not tip bike to left side while cover is off. Ruined a brand new garage carpet.

if it ain't broke don't fix it.

That extra thousanth of an inch won't make any difference. However, I usually set my gaps a little on the high side, even .017. This is just to allow for wear, As they wear, the gap will get smaller.

In the shop manuals for the CT70, it says to set between .012-.016, but doesnt say why or whats best. Setting @.016 will make the top end speed alot better than .012. It simply is a better timing advance.
