Hey everyone, so my story starts like this, bought my first (2000)CBR600F4 at the start of summer, was loing this bike driving it as much as I could with friends and lots of bike runs.. Then by myself one day of course an old lady decided to cut me off, and down I went.. Left with a broken collar bone, destroyed bike, and a cracked crank casing.



So now I'm looking at replacing the motor and rebuilding the bike.
In my situation replacing the motor and doing the work is nmore cost effiencent as far as insurance issues with me..

I am pretty mechanically inclined, just inexperienced with motors, I work as an apprentice millwright/industrial mechanic, just could use some help with the issue..

So if I go the buy an ebay motor and do the replacement, what am I looking at for complications? Do these motors come with the transmisison? And is it as simple as dropping it in and bolting it up? Does anyone know where I could find a step by step process of this? Some points for a beginner mechanic would be appreciated ! Also ill keep ya's updated on how it goes if your interested.

 

As long as the are the same year, and you buy a complete motor (they come with top end and bottom end (transmission) Then it should be a mechanically simple as plugging a mouse into a computer, unplug old motor, drop older motor out, raise new one in, plug it in and turn it on. Essentially, there are always complications along the way, but that is the basis of it. If your carbs are still in good shape, you might be able to save a few $$ buyig a motor with no carbs and just putting yours on it.

 

So I've decided to keep the motor I have. I tore the bike down removed the crank casing, and brought it to our local community college and welded the case. I've started the rebuild, the motor is back together, and now I've run into wiring issues.. I don't know much about the wiring, but have started to tackle it a bit. Here's my problem now..

I have no power, at all, battery is charged.. I replaced a fuse that was blown, and chased wires all day..

The only thing I've found so far that could be the problem, but I have no idea is.. The postive wire goes directly to a little fuse box with a 30 amp, this is blown.. The canadian tire is closed and I can't replace it till tomorrow.. With this big guse blown.. Would that cause absolutely nothing to work? Also the only thing that is diconnected is the taillight, but I don't think that would matter would it?

 

Yes, that fuse is cutting off power from getting to anything. once you replace that, as long as everything is hooked up, it should turn over.
