Please help bike wont run cold
Aright I'm real new to the streetbike thing but, I'll keep this brief, i bought a 06 cbr600f4i that wouldnt run, would crank but didnt run, the guy had crashed the thing and itd been sitting for a while, well after taking it to my local motorcycle shop and putting $700 into it there he got it running after replacing the fuel pump assembly, now it runs, but only when warmed up, takes forever to start cold and idles at like 500rpm's until warmed up somewhat, it also has pretty poor throttle response and takes a while when riding to get up to speed. When it's warm on a sunny day it'll run with ALMOST no issue. Anyone please help its almost riding weather and i wanna ride. I've checked the pressure regulator and no gas came out the vacuum line, shes also got new spark plugs (NGK). Like i said once warmed up she'll run fine, idles at 1400rpms and has OK throttle response.

Im leaning more towards this wax unit being the issue, I do need to find this little box and determine whether its toast or not. Anyone have a link to a replacement?

The wax unit is on the throttle bodies, it has coolant hoses on it.
Your bike linkage should be set to have a fast idle, like 3k, all the time. The coolant heats up the wax and the linkage gets pulled down to warm base idle, about 1200. If the unit is stuck in warm position, the cold engine will have trouble maintaining rpms.
