Last two days small test drives. 3 times the Simmerrings rubber seals from points advance are popped out, oil every where
To much pressure inside the engine. My investigations lead me to the engine breather. Bingo, the original rubber of the breather reduction has swollen. From outside this piece looks alright. But no air gone through it.
I throw it away and swapped on a tiny reedvalve from an car...
Now sky is the limit. I accidentally throw it in the five gear to 7200 RPM with no power los. My personal limit was 6500...
But I must mention that i have a one teeth smaller rear sprocket. Till this head 130km/h was the limit for the engine, above no power. Now only my personal red rpm scale is the limit. There is no loss in power still over red. Also I must mention that the head adapted spigot manifolds are to long, so today I ride with the original one's. If I have finished adapting the spigots there will be more power.
I like it very much
This engine rocks the limit
Thanks jack! Thanks folks!
