  • Category: Four-stroke
  • Brand: O.S.
  • Price: £150.00

Having a bit of a clearout of the engine drawer. I picked this used 90 Surpass up several years ago through this forum. It was destined for a biplane currently being built but decided an 70/80 size would be more appropriate. The engine is in superb condition. Comes with the usual exhaust and knuckle. Engine is in full working order, has good compression and smooth bearings. The valve gaps were re-set before last run. Very clean, lovely runner. Price shown includes post. Open to a sensible offer. Photos are in my 'for sale' album individual pics:
