Gearing on 163 for Rev

What my options

I have two 07 i just put 163 tracks on, one is a stock 163 xp track going on a 07 Summit with 2.86 wahl bros drivers and the other is a 163x2.5 3 pitch going into an 07 Summit with drop and roll avid 7 tooth drivers both machines running aft head, reeds and Noss,DJ kits , i'm trying to re use some of the gearing i have laying around which is 19t, 45t, i believe i may have one or two 21"s kicking around. We r gearing all our 3 inch tracks at the 2.5 mark,

Does it matter which way i reach a Ratio
for example 2.33= 49/21
2.36= 45/19

Thanks

I had 19 47 with a 151 and then a 159. Worked good with the longer track. The 151 was snappy but I think lost some top track speed

I think the biggest you can get tin the REV in a 47 bottom. Ran 19-47 in mine also and it worked good

yes 47 is the biggest gear that will fit the bottom with the chain on it.....

i have a 47 id sell mabe.... has mabe 4 rides on it...

thanks guys, i decided to try the 19/45 , i peeled the chaincase off the holz maxwellbuilt last year and tha what was in it so the boys can try it first trip and swap bottom to a 47 after if they want
