Thanks for the drawing and info. I looked closer and unless I'm mistaken the top gear is a 15wide (20T) like you said, and it shows the bottom one as a 13wide (44T). Is that right?/make sense?

if they have a 15 link wide top gear, then they will most likely have a 15 on the bottom also, if there is a 13 on there the chain will float a little on the bottom gear. * * also the extra rotating weight will sorta suck. * every little bit counts when racing
also, on a 700 they will probably have 13 gears and chain,(2000 t-cat came stock with em and I only snapped on chain this year) * * * * unless your snow-X racing or running more than 210 HP, 15 link chains and gears are no use, IMO
