Sproket and speedo

Hi there I have recently changed my front sprocket to a 14tooth but at the same time I changed my rear tyre to a 140/80 so per all the gear ratio calculators it should be the equivalent to adding two teeth to the rear sprocket instead of three. All is well I love the feel of the bike. But one thing that has baffled me, I have put my gps on to check the speedo and it is reading perfectly spot on to .5 of a km/hr I would have thought the speedo would be reading higher than what I am doing with the sprocket change. Im very confused

My Ten is stock sprockets and runs 10% slower than speedo ie 66 on dash is true 60km/h 110 is true 100km/h. So without doing any calculations it sounds like you have now a true speed matching the under-reading speedo.

Yea it's almost spot on but I would have thought it would have gone the other way going down a sprocket on the front.

Disregard the muppets at the bike shop put a 16 tooth front on instead of a 14 I thought I was going crazy until I pulled the cover off and there was a 16 tooth sprocket.

That makes sense!

How do you find it pulls? Over geared or OK?

Over geared but went fine on road had to change down to 4th with any hills at 100km but was still very rideable didn't do any off-road. But I think if you were gunna do a few thousand km on a long trip would work fine for hwy stuff.
