Suitable oil for premix in a 430

Hello everybody
I am looking to choose a new oil for my '87 430. I can get hold of several brands easily so I would like any advice. I intend to keep running at 32:1 mixture as it is already jetted for this.
My understanding is that I should look for an oil that reads 'JASO FD' or better in it's sprcifications.

Motul - readily available to me
Castrol - previously used TTS Extra with good results without problems. I have been told that it has been rebranded as 'Power 1' - is this correct?
Ipone - made in France but new to me
Belray - need I say more

There are other brands that I can get - just a problem making the time.

Maybe my question should be - are there any oils that I should steer clear of ??

Thanks in advance for any advice

dig and you will find countless blogs on this at this site

I've heard that IPONE are better in publicity than in action .

Golden Spectro works for me in my Vintage Bikes.

All of the oils you listed are fine. Choose the one that makes you feel warm and fuzzy and ride off into the sunset.

On Friday I made the time to visit a friend at a local off-road repair shop here in Christchurch. The owner, Linton, at Dirt Action Cycles' is a 'Europhile' from years ago and he still rides when he gets the chance.
We had a bit of a chat and he enlightened me about various oils.

He told me that ,yes, all the above brands are very good for our vintage of bikes but - DON'T GET THE WRONG GRADE. Apparently some of the grades are so advanced that they are actually not suitable for our riding styles. We need an oil with a medium or intermediate volatility level - oils advertised with high levels are not good. Very high volatility levels require very hot engines that are at full revs all the time to burn the oil completely - our bike will never get that hot. Our engines will not burn off all the oil and so the system will eventually become gunged-up inside.

Many many years ago I used Rockoil products - until they seemed to become scarce on my local scene. Linton is now stoking the current product lineup so I settled on Rockoil K2.
If a shop owner / mechanic / rider recommends a certain product AND can explain why - then that is good enough for me.

Thank you for all the comments

Rock Oil will serve you well. Unfortunately it's hard to find here in NA. Ride on...
