Thanks....actually, I've done a few things, mostly functional improvements. Engine performance-wise, I use a K&N air filter, and I modded my snorkle (cut the bottom off below the housing mount, and cut the right side off the snorkle mouth. This allows concentrated airflow, yet prevents any rain water from entering the airbox), and now the TORs mod. I've noticed increased performance. Have no need to play with the carbs. I'll post a picture of my SM.
