Topic: My CB750 K4 project bike. Now what!?

[David]

Here is my 1974 CB750 K4 project bike.  This will be my first attempt at a rebuild.  Kinda scary but it should be a lot of fun.

The bike has been sitting for several years.  The PO told me it was running but did backfire a bit at the time he stopped riding it.  I assume the first thing I should do is pull the carbs and give them a good cleaning/rebuild. 

I will have a lot of questions.  I look forward to the expert advice that I have seen posted on this forum.

what do you mean with rebuilding..
-get her to run good and drive it
-strip her down to the last bolt and rebuild from the ground up

first i would do a general tuneup,points,valves,carbs sync. etc.

My thought was to get it running and check things out to see what needs to be done.  I suspect it might have to be taken all the way down but I don't know that for sure.

Hey, if you wanna get rid of that sissy bar/luggage rack combo I would be very interested.

first make sure the engine is still turning free, change the oil too.

Nice! just get it running and ride it, then do more in the winter if you still think you have to.

I agree.  Do what needs to be done to have a safe, running bike and leave the cosmetic work to be done during less than ideal weather.  That's my plan for the summer.

Wow! That seat is bigger than my whole bike! 

Seriously though - I'd try to find a set of stock forks, a stocker seat & some new bars (maybe a $100 investment) - riding that in its current configuration looks like it would be a #$%*. I was born in 1970, but I never learned to ride a bike like that. #$%*in'!!!

+1 on doing what needs to be done safety wise + basic tune-up/maintenance stuff first.

Thanks for the comments.  It sounds like a good plan to do only what is necessary at this point.  I believe I should clean the carbs, do a tune up and see if I can get it going.  I'm not in any hurry to get it looking great right now.

I really do want to do something with those front forks.  They make the bike a little too tall for me.  Also, the exhaust does not fit.  I have interference with the center stand.  And, there are no baffles in the pipes.
