When rev it at idle its more like a ploom of smoke. Also, right after revving, I can barely see it but, at idle its smoking some too, if I use a light in the background I can see smoke on idle. I've double checked for spark. It has good spark at all four. The coil tips seem to be making contact even though I havnt ried bending them out yet. As far as vacuum check, I've had the throttle bodies off and cleaned/ synced, I sealed all boots were they attach at motor and air box with black rtv, all vac lines look good and don't leak. I've sprayed nearly a whole can of carb cleaner around throttle bodies while running and find no leaks.

Another thing is that it consumes a considerate amount of oil when I ride it, especially after rides at higher rpms. And spark plugs have signs of burnt oil (ashy white on the tips of two plugs)

If your just tired of spending money take an injector out of a cylinder thats off and swap it with one that is close to the right stoiatric ratio. You can usually tell a lean cylinder by letting it run till it warms up and look at the header tube of that cylinder at night it will glow or use an infra-red thermometer there will be 100° or more temp difference. If the lean cylinder stays lean after u move the injectors then ur injectors don't need tested they are good. On a side note check injector o rings while switching if it's cracked or seated wrong that will lean it out. If you don't get results wit the injector move then move on to the plugs and coils and do the same. If u still have no change then u either have vacuum leak, valve, cylinder/piston, or ecu problems but usually it's injector or coil/plug gap. I'm having a single cylinder lean problem right now and I found a injector the culprit. Hopefully this will help u save money and find ur issue
