Came to the same conclusion, he uses strawberry "smell" 2 stroke oil, transmission oil smells of strawberry's, looks like new crank seal has failed after only 400 miles, not happy.

Had a call from my pal had the white 89 saying oil coming out of crankcase breather, engine completely rebuilt previously with new con rod and seals all round. Any suggestions?

Good example of false engine no, original ground out.

straight from the hip!

Make sure you get the right loom for year, early pre 90 differ and not sure of later years, good luck with that one!

This is my beloved grandsons pw50, bought in the summer as " yes mate, it's fully rebuilt and sweet as a nut!" Bullshit, " it's rough as old dogs balls but I have done enough to get it running while you are here!"
Being an old bastard I knew the truth but it was local and cheap(ish) so bought it anyway, the truth is it spills oil faster than BP and is a pig to start. Finished new shed /workshop so stripped it down fo rebuild to get a clear garage for the 88 rebuild asap. Barrel worn and carb has more crap than Jonathan Ross, but hey ho, have new seals and barrel/piston to go on so should be straight forward, but feel the urge to powdercoat wheels and frame before it goes back together. At the current rate of growth of my grandson he will be taller than me before I finish!

Would not hurt to put fresh oil in and seals, make sure you clean all the gunk out of the fork legs, progressive fork springs would be significant improvement. If you are using new springs would keep same oil weight to start off, otherwise could be over the top. Ask spring suppliers for reccomended weight come to that

Went out for an end of summer nimble today out the back lanes on my red bike, not sure what the policy is around the country but Hampshire charge you for disposing of diy/building materials at the refuse tips. Coming round corners and finding rubble bags in the middle of the road, along with corrugated roofing, asbestos, etc is a real p off. Has been getting worse over the summer and they literally dump in the middle of the lanes, looks like car drivers have just been driving over it as well.
Ah well, winters coming, perhaps that will keep the losers in their box.
