KDX200 1990SR - Sprocket Ratio 14/43
Posted: 09:32 pm Jun 13 2022
Hi guys
I know that this topic has been flogged to death but I have a specific question that maybe someone can help with.
The stock E model gearing is 13/47.
The stock F (SR) model in Australia is 14/45. (Noted that this is with a 28mm carb, restricted expansion chamber, restricted air box and possibly different ignition timing)
My 1990 SR has full DG exhaust, boeysen reeds (rad block), Lectron 36mm carb, E model airbox modified, BP8ES plug.
I will be doing 50:50 Road (including highway) and trail (some hilly stuff)
I am leaning towards 14/43 which is just a couple of rear teeth taller than stock. Do you reckon this seems a feasable option??
Has anyone in the US gone this tall before?
I purchased the bike with 12/50 and it pulled pretty hard down low but didn't really get it to 6th gear yet.
First thing I did was strip it down and a full restoration so didn't test much - Pic attached
cheers
Rick
