as the front overdrive is going to increase, i believe you will need to run bigger tires..
maybe change it to the 0mm (24t) pulley to make up for it? and run a 1mm split? - or if someone is good at this stuff, can they workout the split how a 41t will change it?
all i want to know is if the stock belt will work on the 41t
the split is easy right? the brake pulley is 21t i thinK? so your rear ratio would be 1.95 instead of 2.0, the front is a 19t and 27t I think? so that is 1.42. side pulley is 19t and 23/24 so 1.2/1.26, and lets say 2nd gear 23/55 (2.31) your final would be 5.52:1
front assuming I am right at 19/27
rear again assuming I am right with the 21
good idea, let me know how it goes. the ratios are close enough that I would run the xray diffs for sure. at my track a 10 minute qualifier will throw my gear ratios off enough that 0.05 OD on the rear will mean nothing to me since I will lose 3-4mm of tire anyway.
as for the stock belt, without being able to measure the outer diameters of each pulley its hard to say but I run my belt at the absolute loosest setting at all times so there is easily room to tighten 1 tooth I would imagine.
