Secondary Butterfly Questions



With the stock exhaust and intake tract in place you likely won't do any damage. They are pretty lean in stock form so everything you change without fueling changes compounds it. If you do anything further you'll need to remap with a canned tune or dyno tune it to be safe and get the most out of your mods.
 

Thanks, man.
 

After my ride this morning there is no doubt noticeably smoother in the first three gears, I am sure it is a little lean, it does surge some in the lower gears at constant RPM.
I can see with a PCV and a good dyno tune to get the air fuel ratio right in all RPM the bike will be great to ride.
