Fixation on reeds after not trying what others who have experience of Bultos above will get you no where. Comparing a modified Yam with a standard Bulto is like comparing an enduro bike with a motocrosser.

A question for those people who have fitted reeds and feel that they have improved the slow running, have they just fitted them to the standard barrel or have they modified the porting aswell?. I have briefly tried a 340 with reed and the engine was very smooth, however the porting had also been modified.
