How did effect your fuel meleage?
At the time of the original installation the kit came with a Harley Davidson Carb, CV 40 mm, millage was poor 25 mpg or less

after some thought and some friends help, decided to replace with a Mikuni 45 flat slide, AMAZING!!! instant upgrade and increased fuel mpg to 32, Bill at Magnacharger was the one that told me about some dyno runs with the flat slide and was helpful.They now have the upgrade kit to add the Mikuni, i would strongly recommend this. Back in 2004 that HD carb lasted 6 months i gave it away.
