leaded/unleaded gas

[marius]

I wanted to ask you guys , I bought my 92' Max in the US where It was running on 9x unleaded when I moved to Israel I continued to run on 95 unleaded they also have a 98 and 99 octane but it did not make much difference and 95 in cheaper (about $4/gal) but they also have unleaded gas which is 96 octane. I was talking to my mechanic which tuned the carbs for me and he sad that it is better for the bike to use the leaded stuff which seamed wierd because I know that unleaded gas burns allot cleaner for the motor and the environment and all that(that is not a real concern here)even though he suggested I use the leaded I use the unleaded but any suggestions are welcome thanks Marius
