I have had a chance to use a Dyno
To test my cr250 based engine after getting a good baseline. I put carb (38mm mikuni )on flow bench got a baseline. Then taper bored and worked the bell area. To a 20% increase .
Re installed on engine and. Reran the pulls. And the graph layed right over the first runs
So next I put a 44mm on just to see. And it did same!!!
Now I’m confused (I have V force reeds). Is that the limit of motor or is there a restriction I need to be looking for? Any ideas
Thanks in advance
