i want to know how much difference a 105 big bore by eric gore makes verses the stock 100. has anybody tryed it

The 105 will do little to a 100. Stroking seems to help the KX 85 and 100 alot.

Mike S what does stoking your bike do?

 

[MikeS]

Adding stroke changes (adds) displacement like boring does but in the other direction (up & down), not across the bore. It also changes the port timing that effects the overall power. Eric had mentioned that certain configurations respond better to adding stroke such as the KX85 and the RM125 (I think).
