You know i hear everyone talking about spending big $ on all this spectra,amsoil,klotz oils, racing gas and there the ones who have to have cylinders bored ,blowing rings and needing top end work I have been running pennzoil 2 cyl marine full syn I get it for 1.00 a quart.I do run yamalube in my cases though because I don't want to change that. Had the 87 banshee for 2 years now and not a problem I mix 8oz for 5gal reg 87 octane pump gas and it runs perfect all the time.I wind it out alot more than most people too I don't like to shift till I have to, Yes I have mods too. pipes, boost,jetted,after market open air,I beat the shit out of it every weekend still no problems. Maybe I am just lucky it had 120 stock pressure when I got it checked it today its the same. whats up with that. I bet I am just as fast as the rest with 10 grand into thier bikes.Not bitching just ,making a point. You shouldn't have to throw good cash away to have fun.Anybody else got an opinion?Tim
