Best Dellorto jetting database

Post by Jaguar57 » Thu Nov 14, 2019 9:19 am

Contribute to this jetting database and get a free evaluation of your jetting in a graph such as you see here. The red graph shows the jetting richness from closed throttle to WOT. Above the horizontal 1.0 line is too rich, and below it is too lean. Every data point needs to be fulfilled. You can make this the best database ever for Dellorto because it is the most complete. Just post your details here and if you want the graph emailed to you in case it looks terrible then just email me at 19jaguar75@gmail.com
