The previous inlets were about 89mm from the throttle body to the end of the bell mouth, so the new ones are less than half that at 40mm. I saw this picture of a Spanish mt07 race bike for sale that appeared to have very short velocity stacks as well. 2 Share this post Link to post Share on other sites

I've road raced motorcycles for over 10 years, most without running an air cleaner or filter. With at least annual motor teardowns, a little extra wear on the rings, pistons, and valve seats doesn't matter to me. Except when required by the rules, I'd say air filters are used on race bikes fairly rarely. Edited February 11 by M. Hausknecht 1 Share this post Link to post Share on other sites
AP996 167 Posted February 11 Got my header pipes back from having 18mm bosses welded, now need some dry weather to get out and log each cylinders a/f ratio. 2 Share this post Link to post Share on other sites

Finnaly finished the project now I start to think on more something eheh. Do you think that the bored throttle bodies would be OK in a stock engine. 1 Share this post Link to post Share on other sites
