Yo dudes, Need some help, might be a really dumb question, but afterall what's Netrider for?? So I got this '85 Yamaha SRX the other day and been having problems getting it to run. After piss-farting around for the better part of a month, we finally got it going on a semi-regular basis. It starts pretty good, stays running pretty good, but it still has some issues. Now I'm exploring other avenues like timing and and the air-fuel mixture, but I asked my self the other day: "Seeing as though this bike is 20 years old, could it be possible that it's supposed to run on leaded petrol??" I've asked my dad and a couple of my biker mates, I've had a scan through what little documentation I could find, and couldn't find anything on the type of petrol. Interestingly, there is no "Unleaded Fuel Only" sticker on the bike, but that could be because it was resprayed privately recently. So what do you reckon? Could it be that my new bike needs premium, or am I barking up the wrong tree altogether?
