RC (i still dont know your name)
go for it, i think you will like it, i did and it definately helped me. It meant i could use 3rd gear a lot more on some corners and had to rely on the clutch less so i could concentrate on holding on more! Most of the tracks here are very SX style twisty so it works well, but even on the fast open stuff i havent run out of gears, even with an extra tooth on the back. its real fun on the rough uphills (Carlsbad) also, lugging it at the bottom of the hill in 3rd, bit of clutch and away you go, front wheel in the air, dont forget to wave at the 4-strokes on the way past (yep, even someone of my spodely proportions)....they always wave back at the next corner though!:)
the bike will seem like it has more power, its there, its firm, but its not violent, its well metered with the throttle and easier to use.
i dont think it will hold you back as you get faster, but i suppose some of our more qualified riders will attest to this, but i suppose it would be easy enough to change back by using a thicker base gasket and removing the epoxy from the transfers etc.
go for it, the best present santa could bring in my opnion! :thumb:
