I'm afraid I have to agree with Claydbal. Valks are almost bullet proof. You do not say anything about how it runs other than it pulls strong. So what's the problem. Stop tinkering before you do more harm than good. Leave the chemicals on the shelf.
Sorry to be so blunt, but it sounds like you're looking for a problem that does not exist.
Ride it and enjoy it!!
I've learned so much from my mistakes, I'm thinking about making a few more.
