Thanks for the input . I have not touched the idle screw but I will check it out anyway. I not sure how to see if the injectors are spraying. I would like to check this out because I pinched the left side injector harness pretty good when installing the engine.

You must do a throttle cal if the motor has had any work done at all, especially the porting. You will most likely need to upgrade the map to one of the maps that were designed for porting. You should really do a throttle cal every time you change the oil. But upon rebuilding your motor there have been many variables that have changed. Good Luck

Brad uploaded a Blaze map when he had the engine. I do not know if that map was designed for a ported engine or not. Could you suggest a map that is compatible? I do mostly dune riding and trails seldom any track riding.
Well, I checked the spark and it is great. the throttle body boots are tight. I pulled the plug I can't say I can see a mist coming from an injector but when the piston comes up it puffs out a mist on the compression stroke and eventually the fuel filters goes dry (tank removed). I wanted to try my D and M kit tonight but I have to weight unil tomorrow to call Optimum and register the software. If my injectors are acting up will the D and M kit show it as trouble?

Not really, a visual inspection works best. That is why I said to look down the throttle body. Looking in the cylinder will only show if it is getting gas, but not if both injectors are firing properly.
