I have been running 45 dells on 2270 with 34mm vents. Not sure if it was the cam choice (163/86b0, but it was much easier to drive with than with the 38/39 vents.
I was going to gut my spare dells for this project, but I think they are worth more in the box. So, for street 2270 what size motorcycle from wich bike tb should I be looking at for a first build? Thanks in advance, Carlos |

Djet works up to 2.4 tested.....not sure of anything higher.
I did 2.4 because I could not find any factual cars, just urban myths. I will say that I did a lot of research and stuck with the stock stroke crank, and fairly stock camshaft....a little change there, but typical early ramp up on the lobs. I recall, but it's foggy, that the longer stroke does some funky things to the air in the plenum and the djet did not like it... At 2.4 which was 71/103 it works fine using the maps from a 411 which removes one of the diaphragms and gave me a simple fixed external adjustment....made tuning fairly straight forward. Rich |
