08 stock cam lift durations
« on: April 08, 2009, 08:15:42 PM »
Hi There

Does anyone know the stock intake & exhaust cam durations on gen 2 1340cc Busa?

I am trying to find out also what sized cams above stock that will work with the stock pistons.

Reading the forum i have seen someone do an intake cam mod on the exhaust side like the gen 1's but in a gen 2 with good hp results and good bang for the dollar.

Many of you would say go straight for the 1441 but this is an expensive option and one that will take place once i can dominate the bike to its potential.

Cheers

suzuki have kindly put in there sales brochure

intake cam 281 degrees

exhaust cam 266 degrees of duration.

valve lift on intake has increased from 8.8mm to 9.0mm

valve lift on exhaust has increased from 7.5mm to 8.6mm

My question now is how many degrees of duration can we have on stock pistons without any dramas?

thanks
