Hiya Mike...

Start with the battery for it's the weakest link in the whole system... To
determine the condition of an Maintenance Free battery give it a
refreshing charge... wait 30 minutes... measure terminal voltage...

12.8 or higher is a good battery...
12.0 to 12.8 is a insufficient charge... recharge...
12.0 or lower... battery unserviceable...



Next check the RC45 Charging System...





Finally jumper the RC45 service check for Codes...

Hello Larry , thanks for taking the time to add all the detail in your reply . I can confirm it's not the battery . It's new and fully charged , it was cranking it over like a good'um all the time . I only stopped trying to start it after about 10 minutes , as I did not want to drain it.
Mike .

You're welcome Mike...
I'd would not begin troubleshooting unless the battery's starting voltage is
greater than 13 volts and the charging system is steady at the prescribe
14.0 to 14.8 @ 5,000 rpm because it is the logical component to your
intermittent problem... at this junction I think we can say that all new parts
failed to fix the root problem...

plugs (3rd set!)
cam sensor
coolant sensor
4 x throttle body inlet rubbers

That would suggest a corroded electric connection is intermittently
preventing the full transfer of volts to the point of hard starting...

My RC45 corroded connections even in sunny California...

I've checked the battery and it's all OK . I tried to start it again today , it turns over all nice and very quickly and almost catches for a about 1 second , but then it doesn't start . Lots more backfiring and I also got a loud bang or two , so at least the fuel is getting through .
I've decided to try a local bike shop , as they will also have to come to collect it .
I don't want to just change the plugs , as this could possibly cure the starting issue for now , but doesn't fix why it won't start . It's just so frustrating , nothing some more petrol and a box of matches won't fix.
All is not lost , I fired up my RC30 today , and it started first try , so currently it's Carbs 1 - Fuel injection 0
Mike

I know how it feels Mike when your prize won't start... too bad we are so far apart or I'd turn those frustrations into joy... for what its worth here are steps to troubleshoot according to Honda...
