Fuel change
 

Just bought a buggy thats been run on Tornado 25%, will it be ok to run it on Byrons 30% as have got hold of a gallon at a good price, any changes I need to make? thanks

you may need to add another headshim since your going up in nitro content,it depends how much it is shimmed already,look on the manufactures website for head clearance details.

Might be best to run on the Tornado as it runs well, could I change to Byrons 25% without any issues?

should be ok rich you might have to play with the mixture screws a little bit just for the fine tuning once you have ran a tank of fuel threw the car but apart from that i think it should be ok
