Yamiya has lots of good parts. I have also a list that grows ;D

Their pricing seems to be going up, but they really do sell nice stuff!

I need to order ignition covers before they raise their prices to heaven as most others.
Some parts have good prices,  other not that good.
Their version of stock valve guides seems to be OK too.

No. A local “polisher” does very nice work and I find Windex window cleaner keeps them clean, and once a year I give them a polish with “Autosol”...... My bikes don’t see a lot of bad weather.

My sympathies! Whenever i’ve tried clear, it always yellows. My local powder-coat expert is now offering clear. Might try it.

I polished, then painted some CB750 forks with 2K clear coat years ago, and they stayed nice and shiny for many years. I don't have that bike anymore, but I'll bet they're still good. Having said that, 2K is carcinogenic so probably better to get someone else to paint them, or powdercoat. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

 I'm buffing up a set of sandcast style forks, they came off of a 9,000 vin bike. I got a set of emgo reproduction fork tubes already, the 450 size seals and snap rings are on the way. After not finding the snap rings on line anywhere, Partzilla found me with an ad for them with a part number I didn't know about.
   After ruining a fork top cap o ring there was an ad for that part also. That had to be an accident, right? I never searched for them or said I needed one out loud.
 One axle cap stud is too short but finding a correct one should be easy, it's close to an exhaust stud in length or I'll rob one out of my junkest fork legs.

Terry
When you say 2k clear, is it a specific brand or is it a specific type?
Sorry for the bonehead question, I see stuff called 2k here and I wonder what it actually is.

2k clear is auto grade 2 part primers/paints/clears. 

Usually sprayed out of a gun but you can get it in a rattle can as well.

Spraymax and Eastwood both have quite a few options.

Wear a respirator(with good filtration)when you spray it and your safe.

I’d be more worried about the American diet killing me than a little exposure to paint haha (I wear a respirator all day everyday at my job).

2k paint is a transdermal absorbing substance...it is absorbed into your bloodstream through the skin. It can and has been lethal to many whom have ignored the warnings. Some survive it. Generally recommended you have paint suit and no exposed skin and excellent ventilation if you are going to paint with it.

This will be the first non Honda part I use on this project. Ultimately (assuming “in stock” one day soon) I will also use a Yamiya “red foam” seat. Their parts are superb, packaging second to none, and quick ship too. Their prices are climbing, but still feel the value.......

Dead right David, if you’re that dumb that you think a mask alone will stop you getting cancer, well good luck with that. Back in the 80’s David, my brother in law, was building a hotrod Holden Torana (Aussie built GM compact) and one of his mates (another David) was an apprentice spray painter, so David asked David to paint the engine bay before the installed the 350 Chev.

I was horrified to see David (the painter) spraying 2K paint in the driveway with just a paper mask, but he said that it was outside in a well ventilated area so didn’t need it. He died of cancer in the late 1990’s, in his 30’s. It’s a great product, but best left to painters with spray booths and breathing equipment. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Good to know about 2k.
And yes, the current standard US diet is a health hazard.
Here on Maui we get a box of local grown greens and fruits each week through local farmers. We also have a small garden for various things thanks to my wife. She was raised on a farm in Napa, Ca. And you can take the girl away from the farm but you can’t………….
Lots of green stuff, local super fresh fish and fruits, great air quality and great weather, life in paradise is good

 I've been watching for another red seat foam for a long time. I ended up poking some red foam scraps through the seat pan so it at least looks red. They sit really nice if you can get one.  I got a price from JT Marks once but didn't buy it in time to get one. Who knew both would soon be gone?

Been too busy with other things, but keep checking Yamiya site for parts that are “not currently available”. Yesterday noticed the “two hole airbox hardware kit” was back, so ordered. Used one on the K0 and they are just perfect kits. One of the few parts that was missing on this bike is the complete airbox.

Still no “red foam” seats.

I hate to say it, but I think you are paying  money to make your bike less desirable.?
 But its your choice.?
 You went from one of perhaps a few dozen original condition  bikes left in the world, to
one of several  hundred semi restored ones....  those are  far easier to find..

Frank..... I’m not going to install a new set of tires and tubes on a scabby, flaking, “tear your fingers off”, set of rims. They need replating. Found a platter that will add “Whitener”, no show chrome. The frame is +50% rust covered, so I need to do something. Otherwise, I planning to use every single, original piece. How many bikes do you have with original 4-4 pipes?

Can someone explain adding whitener to chrome?

Not me.... try calling a reputable plater. Cambridge Chrome only do “show chrome” for cars, boats and bikes. They suggested this tactic when I was concerned about overdoing the shine.
