Im a bit new around here so hello everyone!

I have a cbr600f4i 2001, has done around 40,000km. And, unfortunately has been sitting in my garage for the last 12 months(not maintained but kept inside), i managed to get it roll started 3 months ago(seemed to run fine) but most certainly the battery will be dead.

So i borrowed the battery from my drz400(battery has 100cca) in hopes of it firing the 600 up (190cca). It sounds like the starter motor is strong but its just not firing up. It doesnt appear to be a power issue but i dont know about all the ecu and electronics, would they cause it to not start as not getting enough power,from smaller battery? Would it be better to keep the original,dead, battery in and use my running drz to jump start it? or perhaps a car?


My next problem is replacing my radiator, damaged due to the fan rubbing or vibrating on it. I used some powder stuff in a tube called silver seal to temporarily fix the leak, which it did. But i want to flush it out with some automotive radiator cleaner/flush. To do that tho i need to add it to the engine while its running.(see above). I am having the rad sent to be re-cored/repaired at a rad specialist , who apparently will make it better than original.

Would the sealant powder have migrated to the engine (not just sit in radiator)? Will automotive flush clean it out of my engine? Is there anything i can do to reduce my guilt in putting such impure substances into the engine?

Will/should i have to do everything else first before i should even think about firing the engine up?
ie oil/filters/air box/sparkplugs

How would i go about draining the fuel if it has turned stale?

Ive heard about the bike showing some sort of codes, that lets you know the status of the bikes computer?

i have removed most of the fairings, including the front headlight, which is the only non cosmetic part i have removed.

sorry if too many questions at once , but i am used to simple one cylinder dirt bikes, much less complicated, any help with any of these issues would be much appreciated

 

well feel like a bit of an idiot but the bike wasnt starting because of the front headlight section i unplugged. that problem is solved.

anyone with any information the radiator flush would be helpful still, particularly from anyone who has used that type of radiator sealant before
