Topic: Project Gin Hime (CB550 Cafe Racer)

[snipcod]

I picked up a CB550 with plans on making it into a cafe racer.  Have many plans for her, and all ready picked a name.  Which means to silver princess, see I already have the color pick out  

My problem right now is I cant decide on how far I wanna go with the motor.  I know I want to hop it up a little bit.  So do I keep it simple or go for broke?  What I'm thinking is using the 550 motor but replacing the crank, cam, and head with CB650 parts, then over boring and using pistons from a CB750.  Then also have a stage 2 port done to the head.  This of course shoots what I initially wanted to spend out of the water.  what to do what to do...      


Here she is so far.  Not much done yet, but theres really not much to this bike any ways.  

not here but this is what it looked like, forgot to take a before pic  










Getting ready to break the crank case open today.  After this though I think im gunna have to wait tell I get my motor back together or have money for a tank and seat

I just removed the head studs from my 550 and let me tell you.. IT SUCKED!!

Good luck on your princess.. name makes me think of the anime hime mononoke..

what size will the engine end up at ??

from what I recall reading on here I think it would end up being a 718cc.  I had no plans of boring it out that big but what the hell, why not!  not I just need 240 bucks to get her bored out.

Hazah! I was able to remove the cyclinder studs without much trouble.  Some penetrating oil and fire really did the trick.  I tired getting the case apart last night, but I need to remove the rotor first.  Any of you happen to know what size bolt I need for a 550 to remove it?

As long as you like Gin & Tonics.  I tell you what you come here and help me, and I'll make all the drinks you can handle

Spent a little time today working on her.  Got the case apart and the crank out.  Im hoping once I get the parts and take it to the machine shop every thing will go back on smoothly.  I did manage to break the screw that holes on some plastic piece though   








Just got done taking a power washer to the case and I must say its looking pretty clean.


O is this somthing I should be worried about?  Or is it normal


These both are on the case where the tranny gears mount

I think the 718 figure comes from paulages hybrid engine...his had the 62mm pistons and the 650 topend...he put a lot of machine work into it to get that 718 figure, far as I understand...

Ya he really went all out on his thats for sure.  I would like to do the same just more scaled back.  Every thing I've read hear you can bore the 550 cylinder sleves for the 750 pistons.  I was looking at about 3k total for my bike, not just the engine work like pauls.
