Would any Indian riders be interested in an UnderDrive Pulley for a 111 ThunderStroke Engine?

Would this just be one more place a rock could cause damage for those of us forced to ride on gravel roads or would it actually help by keeping the slack out?  I'm assuming this is what I'd call an idler pulley potentially spring loaded. Maybe you are referring to something totally different.

This is your Drive pulley coming off of the transmission to the rear pulley on the wheel.

I'd rather have a overdrive pulley. (larger). The bike is geared too low\.

Since he's not talking about a idler pulley, I'd agree with you. A slightly larger would be much better so I wouldn't be interested at all with what is being offered.

Perhaps calling it a 1 tooth smaller drive belt front pulley would be far less  confusing assuming that is what it is?

Do you have a way to correct the speed-o-meter with an under-pulley???

No we do not have a way to correct the speedometer.

Speedometer on these bikes reads from the ABS sensors, so actual wheel speed is used. You can change the pulley ratio without having any effect on speedo reading, unlike a speedo that reads from the transmission like some older H-D bikes. (Some of them read from the front wheel.) Changing tire outside diameter is the only way to change the speedo reading.
