So I completed a pair valve mod last night. I just blocked the holes using a boat and Hose until my plates arrived. My bike will now not start or run u less the choke is pulled out all the way. Half way it sounds like a car with cam. All the way in just cuts off. What did I do. Also with Choke on. No popping but blk smoke. Just assuming that’s cause the choke is all the way on and it’s the fuel.. it ran fine before no issues and changed the plugs last week before the ride. All was good. I know I just crossed up something some how. Just don’t know what.
