Well I had a rain day today at went to the local dealer an picked up a 14 front and left the back at 40. Its deffinately a lot faster. I can still pick up a 15 if i think i need it. I can still make a hard launch in second taking off, which is almost making me think i do need the 15. bad thing is the chain practically has no ajustment and thought about taking off the bottom chain guide to give up some needed slack.
I forgot to tell u my shee is an 88 so it came stock with a 13 tooth front.
so what do u guys think about running turf tires, my guess it depends on the track.
anyway thanks tons for the input its greatly appreciated... ~Joe
