Doms CB550F1 project

[DomP]

I have no intention of putting it all together without cleaning those threads up so don't worry about that, when doing work on my cars I've always used copperslip and reduced the torque 5-10%.  My thoughts were in alloy I'd rather not risk slippery threads and lower torque on gaskets

Ted, you'll be pleased to hear I spent a wile on my studs and threads lastnight.  Got them nice and clean then a wipe over with some oil until I can get it all back together again.  The threads were quite dirty but perfectly formed, no damage evident.

Has anyone painted over powdercoat?  My frame has a few scratches and chips that I really can't be bothered going to the trouble of stripping it for, I tried touching them in with Rustoleum combicolour as it's what I painted my XS650 with but it's very obvious that it's a different black and sheen level.  I tried rubbing it back with some 0000 wire wool to matt it but it hasn't worked.

I'm now thinking of keying the entire frame and painting over the powdercoat with combicolour.

Guess it would be like painting plastic maybe. The first time my 750 frame was powder coated it got a mark on the rear frame from taking it out of the oven. I5 was only about the size of a finger nail but unfortunately on a visible part of the frame. I suggested touching up with paint but the powder coated said no and acid dipped and stripped and coated it all over again.

I believe Hammerite Smooth will pretty much stick to anything so if out of view shading might not matter

I think I'll get it out in natural daylight to make a decision, if it stops raining!

It used to, but like a lot of the good stuff its been altered and aint so good anymore

Combicolour is really good Bryan, flats out even when brushed on which is one of its claims, even better if you warm it and the workpiece while using it.  It does claim to be ok over powdercoat as its recommended for industrial use on machinery etc.  I'll do a bigger test patch I think then give it the scratch test!

Yesterday I bit the bullet and lopped off the rear seat bracket to weld in my upswept hoop, I've not done much welding but nothing watching a few YouTube videos couldn't sort.  I've noticed another peculiarity with my right foot peg, it's an F so has the fold up peg but when down the rubber sits sloping forward rather than being horizontal like the left side, could it be a peg from another model?  It looks identical to the parts fiche on CMSNL.

A bit of a side note but I've noticed my frame and engine numbers match, I thought this rarely happened and given the mix up of parts on my bike I'd assumed the engine may not be original.

I believe it might just be common wear on the footpegs - my 500 ones are the same

Ah you're thinking I mean not horizontal sticking out from the bike but I mean as in rotated about their axis.  It is l located on the frame tab correctly.

They can get bent if dropped at some point, also designed to rest against the kick-start.

Remove the footrest rubber Dom and check to see what shape the bar is, the 500 and the 550 used different shape rods, IIRC, the 500 used square type and the 550 flat type. As the 550 uses footrest rubbers that are held by bolts going through the rubber and threaded into the bar and the 500 doesn't have that, if you swap the bars over and drill holes for the bolts unless you get them right they don't line up and the rubber sits at an angle.

I think you're misunderstanding me, it's not bent it's rotated to the wrong angle which isn't possible from a drop.
