I would recommend. ....
1.Keep tappets at factory specs
2. Stop worrying about top speed. There are sooooo many factors that determine top speed, such as wind, riding postions etc, not just the tuning factor. Even my gs150 does 118 on some days while on other days it refuses to go above 110.......and did you say you touched 118? And you are still not satisfied with tuning? Come on bro
3. As long as the pick is ok, and your fuel average is fine, don't play too often with the tuning. .....dont you just hate every time the mechanics strip your bike naked?
