Please Help Me Check My Chrome Plating List

[markb]

I’m going through my parts to get everything ready for plating for #97.  Can I get you experts to scrutinize this list and make sure I have everything correct for chrome?  I don’t need all of these pieces chromed but I figured I might as well make a complete check list.

Here's my edited list (4/28/15):

Seat strap clips and screws
Front brake hose bracket
Point cover
Clutch adjusting cover
Starting motor cover
Gear shift arm and bolt
Kick starter joint
Kick starter arm and bolt
Mirrors & nuts
Handlebar
Front fender & stays
Rear fender
Fuel cap & check
Mufflers
Rear Brake Arm
Rear Brake Pedal
Chain Adjusters
Front & Rear Rims
Side Grip
Rear Shock Covers & Springs
Brackets & Bottom Plates for Tach & Speedo
Headlight Rim & Retaining Ring
Turn signal bases
Fork boot bottom collar
Fork cap bolts
Steering stem nut & washer
Shafts & washers for turn signals on headlight bucket
Tail light base & number plate bracket
Ignition switch washer
Cap nuts and washer for top rear shocks
All bolts, washers & nuts for the handle bar clamps & top bridge
Brake line screws for banjo ends (before VIN 2720)
Six bolts for brake disc
Front fender stay mounting oval head screws
Swing arm pivot bolt and self locking nut
Bolts, washers & nuts for mounting turn signal bases on stems
Lower shock mounting bolts
Kick starter knuckle pin
Clutch & brake lever pivot bolts & nuts
Exhaust pipe joints
Exhaust pipe flanges
Rear axle, washer & nut
Clamps & screws for rubbers from head to carbs (carbs to air box zinc)
Horn
Caliper Adjusting Spring
So by default I believe this means that everything else that's shiny and not aluminum is zinc plated.  Thanks for taking the time to check this out.  Maybe this will be helpful for someone else (whose anal too).

Hi Mark,

I think that your oil tank cap is stainless steel. It is at the later models (K0 - K2), but probably also for the sandcast. You can polish that cap with alu polish

[Steve Swan]

Yes also; I've only seen stainless oil caps

[markb]

This is why I talk to you guys.  That makes sense, I'll double check mine tonight.  I was wondering what I was going to do about the dip stick.  I'll update my list accordingly.

This is my K2 cap after polishing

Hi Mark
Lower shock mounting bolts - Yes
Kick starter knuckle pin - Yes
Kick starter arm bolt, 8x28 - Yes
Clutch & brake lever pivot bolts & nuts - Yes but I would buy new
Front axle & nut - No Zinc Plated as far as I know
Exhaust pipe joints - Yes
Exhaust pipe flanges - Yes Mine are
Rear axle, washer & nut (on head of axle only?) Yes but I think the whole shaft is also chrome plated and maybe resized. That is a good topic as I really can't say with this
Some of the smaller items I tend to buy NOS as the finish with re-chromed stuff is too damn good. Each to their own though
AND the carb clamps but these are satin chrome I think

[markb]

Marcel,
That looks great.  It looks like chrome doesn't it.
KP,
Thanks for the comprehensive answer.  I agree it's better to buy the little stuff too but also because it's cheaper than having it plated.  It's even true with some of the bigger items.  For example, I've found it's cheaper to buy handlebars than have them replated.  One little thing I'll have to rechrome is the oil bolts obviously because they're not available in chrome.  They're going to look great with your beautiful hoses.

Re:  Plated finishes for intake rubber manifolds, airbox intake horns and bolts.  

Every CB750 i have seen, 69-onward, the 8 clamps for the rubber intake manifolds have a different plated finish than the 4 clamps for the airbox intake horns.

The manifold clamps appear to have a fairly bright chrome satin sheen to an almost nearly shiny finish.  

The airbox clamps appear much less shiny than the manifold clamps.

Manifold clamps appear to be chrome plated, am sure steel not polished and probably no copper base, perhaps this gives the satin sheen appearance.

Airbox clamps appear dull in contrast to the 8 clamps, appears zinc.

If my memory serves me correctly, seems the manifold clamps are a different size than the airbox clamps.  Cannot remember if there's different pns for these clamps, seem to think there is......

I've also noticed finishes on all bolts are not the same; range from a satin to a shiny.  Most have a satin sheen, but there are others that are shiny.  Larger bolts in more prominent places are more shiny, smaller bolts less shiny.

The 8 manifold clamps are chrome - sometimes full chrome, sometimes less so. The 4 airbox rubber clamps are bzp.
Parts list gives different part numbers for these, presumably due to the different finish. My parts list also shows that the chrome clamps (300 middle number) supercede to to the same part number (230 middle number) as the bzp airbox ones. Presumably therefore these are the same size.
Re-chrome of the original manifold clamps can be a real problem if they are in poor condition - polishers tend to get carried away and destroy them, or at very best return them with custom chrome finish. Maybe the bzp ones could be stripped and then re finished in chrome if original chrome ones missing, or too far gone to restore?

I observed the same thing with the part numbers.  Excellent information.  My manifold clamps may be in good enough condition to rechrome without over doing it but I like your idea of using the -230- clamps and chroming them if need be.  It appears that the -230- clamps are available from Honda.  By the way, bzp is zinc plate?

[Wayne]

I beleive BZP is Bright Zinc Plating Mark. All of my clamps were rotted so I'll be watching thsione closely as well.

[markb]

Thanks for all the input guys.  I've edited my list to reflect everyone's comments.  This should be a pretty complete list of everything I need to rechrome or buy.  Once I get that all sorted out I'll go through the zinc.

[markb]

I think I missed an item.  Is the swing arm (rear fork) pivot bolt chrome too?  One more question, has anyone ever seen an "8" bolt chromed?

[Joe K]

As far as I know, the pivot swing arm bolt is chrome and the nut on the opposite side.  I think all of the "8" bolts are anodized, but not positive.  I purchased the set from Yamiya and they are still new.  I chromed several "8" bolts last summer and the chrome covered up the "8" on the bolt, so I wouldn't advise to do it.

[Steve Swan]

I have only have seen chrome on the swing arm shaft and nut.  I do not recall ever seeing any "8" bolt chrome plated; only zinc.
