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 |

As a general rule, you step one size DOWN for ITBs when switching from carbs. ITBs flow like crazy. I wouldn't go bigger than a 40mm. That said I have 45mm ITBs on my 2316cc and they are a bit too large. 42s would probably be more appropriate.
I second Mats suggestion of the ITBs from Mario (www.thedubshop.net) and Tangerine racing's cable linkage. The linkage is like butter and I havent touched it in 18 months (20K miles) and it was still spot-on 2 weeks ago when I checked with my flow meters. You'll NEVER say that abut X-bar or even twist style linkage. |
