Rough starting after engine rebuild. ***FIXED***
Having a few issues with the bike since I rebuilt the engine. 2005 CBR600RR
First off the temperature on the bike after sitting overnight in the garage was 190 from a cold start. It was 65 degrees last night.
I get the bike running and the temp climbs FAST. It went from 190 at a cold to start to 230 in about 30 seconds.
Second issue is that the radiator fan never came on. Searching the forum it looks like it should have kicked on around 220. I checked the relays and they appear to be fine. Haven't checked the fan itself yet but it worked before I pulled the engine.
Third... The engine is rough to start. I have to hold the throttle wide open and feather the throttle to get it to start running. It does this whether it is hot or cold. It almost seems like it is flooding out when it starts. Once running, it idles fine and the engine sounds great now.
I did some searching and the only other person on this forum with a similar issue said it was a kinked vent hose. I checked all the hoses and even lifted the tank to start.
That was not the issue.
Any ideas what the hell the fix could be to any of these? Any suggestions would be greatly appreciated. I have exhausted the search function on this forum. I had other issues and was able to resolve all of them by searching the forum.
I just can't seem to find an answer for these last three issues.
I have a factory service manual and have tried everything it mentions.
