06 question

Recommended Posts

allright guys I have a question. i was in the local honda dealer and picked up a brochure on the 06 450r and it says valve seat material changed for improved durability. so my question is are the 06's really holding up better, I mean does anyone know of anyone with valve trouble on their 06

My 06 has 55 hours on it. Both exhaust valves were at a little tight when I got the bike. I reshimmed them at 3 hours. I have since checked the valves 5 times (every 10 hours) and they have have not moved at all. Still perfect after 55 hours of nothing but motocross

I am interested in learning this as well since I plan to purchase a new head before it is sent off to RHC for the full treatment. What about the 07 head with the smaller intake valves??
