Wossner pistons vs oil burning
Hi I have recently become the proud owner and rider of a 1990 (ish) Tengai, which for the most part is very enjoyable! however the subject of oil consumtion has raised its quite consideable head! Initial thoughts of smoke on start up led me to replace valve seals with no difference noticed. Then as I read up on the subject a little more I found this forum and the many pages and theories around the piston and rings! Unfortunatley it seems the 685 big bore will not work with the liner on a bike of this age, so the other option is a replacement Wossner piston. Has anybody any experience with these on the 650 engine? Will this help my impressive 1 liter of oil in 200 miles being burned?
