Just asking.
Wont a 15w50 be better as it is still thick at a higher temp? a 15w40 is the same as the 50 but should the temp go higher above the 40 'the 50 will take care of it'

if your bearings are worn, then 20W50 will be better. But the W50 makes the engine run hotter - read viewtopic.php?f=4&t=38124&p=327274 for a brief explanation

Your oil pump is a positive displacement pump. I.e it pumps a certain volume of liquid each rotation. Whether your oil is thick or thin it makes NO difference to the flow rate. Air cooled motors run hotter therefore oil is thinner which is a problem for bearing life. I would not use a thinner oil than 50 on a beetle motor. Especially in summer months.

Thanks Tony.
What would you recommend for a single cylinder four stroke watercooled motorcycle without a oil cooler?

If water cooled, then normal high performance castrol will be fine.

Thanks Tony yes oi lnow its a gear oil but what i wanted to know is whether anyone has used it before or know someone that has.
Reason i am asking is that we have 5 x 25 gal drums at work that we will be scrapping soon and wanted to know if there would be anyone interested in some..
We also have alot of a product called Belesta which is also an additive for gearboxes.

For motorbikes you need to get motorbike specific oil as you’re running a wet clutch. Else you might struggle to change gears. Motul or Belray 4T oil
