Crank seals & O-rings for BS 90 Trail
« on: August 04, 2025, 06:10:07 PM »
Hi all, can someone give me the part numbers for all the O-rings and oil seals required to properly seal the crankcase on my BS-90 Trail. It is a pre-mix model if that makes a difference. The schematics show two seals on the left side 09090-106 and 09090-107. Right side looks like 09090-108 plus the 100mm o-ring and a smaller o-ring on the carb inlet tube. Why are there two sizes on the left?
