Honda Valve Shims?

Recommended Posts

I used Honda shims in my WR450 because they come in .025 increments rather than .05 like Yamaha. Lots of big bikes (450cc +) use the same valve shims.

Honda uses both 7.48mm and 9.48mm dia shims, both in finer increments than hotcams kits have. There's no beating the value of a hotcams kit, though, and we do use them here at the shop.

7.48mm is used in all CBR sportbikes. 9.48 was used in early TRX450r's 2004 for sure probably many other models.
