'82 cb650sc project

Postby kerryb » Sun Oct 28, 2018 10:05 am

Hi, new here, new bike. '82 650sc going for the "cafe lite" treatment for the first time around. The plan is to minimize the cruiser look with changes to tank, seat, and handlebars, without compromising the stock frame yet. Having some difficulty researching which tanks might fit. The stock tank from my '78 cb750 is too narrow at the mounting pockets, as are all the vintage beemer tanks I saw yesterday. I read somewhere that a gt380 tank from suzuki is a good choice. Can anyone suggest another choice that will fit without modifying the tank?
Pics to follow.

Here are the promised pictures...as we got it and initial mockup of possibilities. the mocked up tank and seat are borrowed from an on-going cb750 project, so they are for visualization purposes. Plans also include handlebars in a clip-on position or a modified set of clubmans. Headlight and gauges would be lowered and gauges would be from an earlier decade so they would be separate from the idiot lights which would be a row of led's

comments welcome.

Over 100 views...and not one comment? You are too polite or I'm on the wrong forum.

Is this hump too big and wide?

It looks not bad at the first pictures but at the last picture the width looks quite much.
Might be just a camera focal width/perspective issue however.

no, it's not the camera angle. This seat was made to use the stock seat pan on a '78 cb750k to retain the seat hinges and latch. I have some other ideas that will be much smaller. will post pics later.
Another question that crosses my mind is whether there is value to having a rear inner fender to protect the back of the motor and the under seat area. I'm thinking a small fender, tight to the wheel, mounted to the swingarm would be less intrusive to the look we are after. opinions or comments welcome. The fender would most likely be made of fiberglass to hug the rear tire.

If you are not going to keep the stock airbox (most cafe builds imply pod filters, so I simply assume yours, too) a fender is probably a quite good idea.

Oh yeah, that!...I'm not going with PODS, been there, struggled with that when the PO originally got the bike. It ran so much better with the pods removed and a stock air box reinstalled. I'm going to keep the portion of the air box that contains the carb boots. The air filter section will be reworked to house a flat style filter, hidden under the seat in a horizontal position. I don't mind carb work, but a proper air box seems to have the best all-round performance, so we are keeping that. working on mockups, no pics yet.

I do have a pic of a little more refinement of the footpeg adapter.
