I started tuning the bike in.
The stock holes in the air box was 1in about.
One of the mods done to the stock box was to drill a second hole.
I made restrictor plates to meter the air intake to match the fuel that is metered by the stock jets. Instead of changing the jets to add more fuel because of extra air intake I will restric the air intake to match the fuel.
I can make different size hole plates until the air fuel ratio is correct and bike runs perfectly not breaking up in high revs and easily adjust for different changes in outside atmostphere by switching the plates out. Also allows me to run any configuration of exhaust I like.
Between this and the 1/2 in washer welded in the exhaust as a baffle I will be able to dial the air intake to run stock jets in the bike.
So, far these 2 restrictor plates are working perfectly.
