Dyno question

[BlackandChrome]

My bike is going on the dyno after it gets the top end refreshed. (2008 XB12R)
I have a drummer installed on it. I left a K&N filter that they'll put on and tune with it. Besides that

I plan to do the right scoop, open air box and breather reroute mods sometime this summer. Would those mods throw off the tune?

 

[Jobe Zeebuh]

yes. DO it all first then Dyno. Best bang for buc

the open airbox may change things slightly. the rss and breather reroute wont have an affect though.

Can't you do the open airbox mod while they're refreshing the top end, that way it's included in the dynoed tune? The other mods would be fine to wait, but I'd recommend all intake & exhuast mods be done before having it custom remapped.
