munch Posted October 16, 2005 Report Share Posted October 16, 2005 we use proper fuel here ,with a higher octane rating so ignore it!! 10months riding no problems Quote Link to comment Share on other sites More sharing options...
barcota Posted October 17, 2005 Report Share Posted October 17, 2005 The 50/50 mix mentioned on the US Montesa site refers to the 315 as part of the preparation of a pre-mix for two strokes. Obviously this is not a requirement for the 4RT. Quote Link to comment Share on other sites More sharing options...

marky g Posted October 22, 2005 Report Share Posted October 22, 2005 The 4rt will be my next bike when the s/hand prices come down to about 2.5k, the cheapest I've seen so far is about Quote Link to comment Share on other sites More sharing options...
