As described above, the cylinders would draw part of the air via the leak, resulting basically in a leaner charge, as some of it would be unmetered and unfueled. The proportion and hence the final AFR would depend on the throttle opening, as a closed throttle would result in more restriction in drawing air through the throttle body an hence more fresh air through the leak. In short you'd be having lean conditions getting worse as the throttle closes and being perhaps fine at WOT.
When the bike is idle, it runs perfectly fine and revs fine when I open the throttle but on the speedometer the needle shakes a little for some reason (like it fluctuates between 2000 and 22000 rpms at idle). When the bike is in gear, it runs but once I open the throttle it sputters. I changed the fuel pump, plugs and coils. Someone said the boots may not be tight so that was the reason I asked what would happen.
