Welcome to the forums.

I moved this over to the Suzuki section so you'll get a better response.

 

thank u

 

welcome to the forum I have a '87 zilla I run 100 octane av gas mixed at 50:1 with MC1 have run it for yrs with no problem am sure you will hear from others to run 32:1 or other mixtures but you hear what they say and make your own decision. But you need to run at least 100 octane in it

 

thank u much i just needed a start point and this is a good one

 

no no no do not run 50:1 that is wayy to lean and will lead you straight into a siezed piston and lots of repair costs on the engine. run 32:1 but i do agree run 100 octane if you can find it. but 91 octane from the pump works just as good as well as 110 octane race fuel which is better for motors that have been bored out. ive owned many two strokes and love them to death but you have gotta run the oil richer mixed with the fuel or the piston will not get lubricated, there fore 32:1 is the safe and smart choice

 

I've had my 87 500r since it was new and always ran 50;1. And i still run at 50;1.
Just make sure the carb is tuned right and you wont have any problems.
I do run half and half mix gas 3 gallons of 110 and 3 galllons of 90 to 92 octain.
With CCI oil. If its a big boar then you may want with a little more 110 in the mixture.
Good luck and don't hert your self.
