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 |

I think the stock bore for a 2.0 throttle body is 45mm. I run a modified volvo throttle body. It is 55mm. The engine size on the 90s Volvo it came from is 2270. I figured it would be a good choice and it was. The Volvo TB requires some mods. it turns the opposite direction and also required me to drill and add a vacuum advance or retard port. I can remember which. I made an adapter plate to fit the stock plenum out of a chunk of 1/2" aluminum plate to test it out. It worked for a couple of years until a machinest I met saw it and modified another plenum properly. I run a modified Djet system. Web cam fuel injection grind. Torquey SOB!
