Not sure of the volume.... Just made it as large as I could to smooth any turbo pulsing. As for the carbs I am going to try to make the factory ones work and if all else fails I will use a carb off a sport quad that someone else was successful with.
I don't know what the optimum size would be but the bigger the plenum the longer it takes to pressurize and the greater the "turbo lag" effect.Not sure of the volume.... Just made it as large as I could to smooth any turbo pulsing.
It should be possible to make the stock carbs work. This is not for our bike but shows the basic steps necessary: https://web.archive.org/web/20081006192936/http://www.turbo-bike.net/Pressurize%20carbs.htmAs for the carbs I am going to try to make the factory ones work and if all else fails I will use a carb off a sport quad that someone else was successful with.
