I had a similar issue, turned out one of the reed cages was bad. I thought it was a carb issue until I swapped reed cages and the problem followed to the other cyclinder.
Im going to do the same.......just curious as to how these are going to work. They sure sound great in the promotional video but way too much money for me. My stock carbs are doing just fine.
St. Claire, Moscow, Treverton (all in PA). Ive been to treverton which was a blast but not the others. I know people who ride at the other spots and they love it.
Lost trails is no place for a banshee. Especially a fast banshee. Be sure to have a rear skid plate or you'll be sorry. Also, lower gearing would be ideal. I will never go there again. You may like it though, everyone is different.
