New member with 1978 CB750 K8 - Basic questions
« on: March 30, 2017, 06:22:13 AM »
Hello everyone

I am jagadeesh from India. This is my first CB rebuild and i am very very new to 4 strokes. I was mostly into 2 strokes singles and twins [ rebuilt 8 RD350's] So please bear with me if you find the questions to be very stupid :)

There are hardly any CB750s in india or any mechanics for them to seek help from, So i will be relying on this site and you guys for help.

I am looking at rebuilding the chasis first and get it rolling before i start on the engine.

a few questions i had on chasis rebuild were

1. Are there any complete rubber kits avaible online that will have all the rubber parts that are needed to rebuild the frame? for example tank rubbers, footpeg rubbers etc

2. What all bearing do i need to change? Front & rear wheel bearing , Swing arms bushes, Tapered steering bearing. Anything that i am missing? Does anyone have a good source where i can source all of them from?

3. I would need fork oil seals and fork caps. Any other seals?

4. Cables for clutch and braided line for front brake. Any good sources?

Anything else that i need to get?

These guys have a lot of stuff you can check them out, they also list the original honda part number which can be helpful.

Welcome Jag!
1. Are there any complete rubber kits avaible online that will have all the rubber parts that are needed to rebuild the frame? for example tank rubbers, footpeg rubbers etc.  no, there isnt, but you can buy all the pieces separately. 

2. What all bearing do i need to change? Front & rear wheel bearing , Swing arms bushes, Tapered steering bearing. Anything that i am missing? Does anyone have a good source where i can source all of them from? David silver spares in the UK, or CMSNL in Netherlands can get you pretty much anything you need.

3. I would need fork oil seals and fork caps. Only if currently leaking Any other seals?  any leaks from the seals on either end of the crank?  behind the points plate, and another around the drive shaft

4. Cables for clutch and braided line for front brake. Any good sources?  Same as above.

Anything else that i need to get?
