going for the air box plenum
 

right after much deliberation, research etc i have decided to go for an airbox for my motorbike carbs. i have made an air box and rolled the front cover so it is rounded in shape i have also tapered it so it speeds the air up i have included a 75mm opening at the front which works out as a larger area than the 4 openings on the carbs i am going to use one of these at the front

it should be interesting to see what and if it makes any difference to the performance or sound of the induction i will put some pics up as soon as it it finished.

Dont forget to use the water pipe to heat the manifold on the carbs as they may freeze up if you dont.
