1. I would look at your W-arm to make sure that it isn't cracking. The W-arms on the SRX are known to be weak.
2. A good carb cleaning can't hurt.
3. Clean and sync your powervalves.
4. Check carbides/hyfax for wear.
5. Grease your suspension/steering.
there's many other things, I'm sure someone else will chime in.
