Doms CB550F1 project

[DomP]

This is the airfilter fitted to it that's had the element cut away for some reason, is it a cb500?

[Oddjob]

No that's a 550 one, the hole in the bottom is where the pole on the piece at the bottom of the airbox sticks through, what a waste of an airfilter, might as well not be fitted. No idea what the hell that bracket is doing bolted to it, that's part of the airbox mounting brackets.


Ahh, I'm betting the spring was missing and that was fitted to space the filter out to seal it against the front. So the springs missing?

If so, this is what you need.

The spring is missing, I was going to make something up to do that job for now but I'll definitely go down the 500 filter mod as originality isn't something I'm bothered about.  I still intend light modifications and haven't ruled out doing a bit of a cafe racer.

Try this fella.

Thanks! I'm sent him a pm so fingers crossed

[Oddjob]

You need to ring Dave Baker at the phone number given in that thread Dom. See if he's still doing them.

[DomP]

Hopefully he still does Ken, I messaged Charlie to see if he remembered what the donor hub was from because the part number no longer exists.

Appears to be a VW Mk3 Polo 1993.

Check the dimensions.

No matter what I do GSF comes up with nothing, those links dont even work for me for some reason.

The ones i used to use where Honda Civic drums, not easy to find and not cheap. I found that aftermarket drums were a lot harder to work with and some even had old crushed ball bearings from when they recycled the steel.
Honda OEM number was 42610-SB2-010, 42610-SB2-761

How about this Dom?

Might be worth a gamble.

Too big on the inside diameter 

[Oddjob]

Thought the original spec was 180mm with a max spec of 181mm, which that drum clearly shows to be the same max spec.

Plus it's supposed to be the equivalent of the 42610-SB2-010 which you listed.

Only just noticed this, it looks like it should work

Having read that 550f's take 25mm fuses I spent ages searching for some and ordering them only to find my fuse box takes 30mm
