I am making a list of things I want to change on my escape piggy when it runs out of warranty. I read several years ago that you can change the internal ratio on 1st gear to bring it closer to second and stop some bogging. by taking the first gear and first gear shaft from an XR600R and putting into the piggy. has anyone done this? Will it work? Then I can change final gearing to make the bike work better on or off road. appreciate any help on this. Thanks in advance. loved the story on putting a kickstart on my piggy. I'll do that soon after I change gearing. .
