i am about to buy an 88 E reg RXS-100 off my mates brother in law, but he is out the country at the moment. the bike is fine but we are unsure of the fuel type he was using for it, if it was unleaded or 4 star. does any one know if this year bike will run on unleaded or will need the lead additive used as we are struggling to find out from him at the moment

any help very gratefull, cheers

As far as I know all Jap bikes have been unleaded since 1973.

4star is only available to classic vehicle clubs and is very scarce.

Hope this helps.
