New Question. did the sync this morning. Found right screw turned all the way in, left out almost a quarter turn. So no surprise there.
What was surprising is I had to turn the left out just over 4 full turns to get them synced. When I did, the idle jumped up quite a bit. Reset it to 1300 rpm and then had to turn the left one back in slightly. Now it's spot on.
My concern is, that seems like an awfully big difference in the screw settings. Am I Ok leaving it like this, or would I be better off pulling them both completely out and cleaning them? My thinking is one may have some clogged orifices causing the different settings, but that's a guess, being this my first FI bike.
I used a Twinmax to set them, which is what I use on my carbed bikes and never had an issue with it. I was short on time, but I plan to check it again at lunchtime, and just reverse the hose connections to make sure no issue with the Twinmax. Thought about also using zip ties on the tube connections to be certain no leaks, but they seemed snug. And like I said, the idle definitely came up as I adjusted to the balance point.
Any insight appreciated. Thanks.
