ride the sled first,this will dictate a gear change.if the gearing is stock,you may need to change the ratio.as simple as this may seem,keep notes.they come in handy

How are you gonna run a 1.5 on a Phazer? I was told the tallest I could go on my Exciter was 1.25.

^ x2. no way that track will fit, without trimming about 5/16 off, or dropping to 7 tooth drivers. careful on your gear selection. some changes in gearing require different length chains. double check gear combos once you know your existing chain length.

drop one on the top and add one to the bottom, or just do one or the other, not both. careful here as certain gear combos take different chain lengths. been awhile since the pz days, are the gears gears, or do they look more like a sprocket? may have some left overs that fit. whats the gear ratio now? need a tooth count on upper and lower.

cant seem to locate any of those gears. look at any yamaha on line parts suppliers microfisches and check out the phazer st model. these were the factory longtracks. see what the std gears were for a reference.

they are the same gears, it just give you an idea of what ratio to shoot for. pat attention to chain length when choosing gear ratios, some require different lengths.

do you change gearing for the increased torqu needed to drive track? if i was going up in motor size and power would i still need to change gearing?

like i said,listen too the old man earlier.i wouln't drop a tooth on the top and bottom both.i would rather drop 2 teeth on the top and leave the bottom alone.if you want to keep track speed up,"do not" drop any teeth on the bottom sprocket.if you drop teeth on the bottom,you will lose mechanical advantage.
