1985 350x Refresh (Rider)

[Shawn Powell]

Thank you Shawn for that information. What muffler setup are you running on your 350x now? I thought you were running a supertrapp after switching from the DG.

I am now , but it's a universal supertrapp I bought brand new. Live and learn. I didn't like the way the old one sounded cause I thought louder would be cool. I'm not that smart. Hated my DG noise and had to make custom setup. Wasn't cheap but was worth it. Sounds better and runs great.

I picked up a 350x supertrapp locally for $65. It needs cleaned up; what is the best way to go about that? I don't have any expierence with supertrapps so any advice would be greatly appreciated.

Nice score!

I would say Shawn is right about powder coating it but..........

If you can get that pipe completely clean and rust free the POR15 high temp stuff or the pj1 stuff would really go on nice and be really durable.

I did my 200X head pipe with 15 after I COMPLETELY removed all rust. I think I used the rustoleum remover as its quicker but evaporust is just as good but can take a day or sometimes 2. It's a little cheaper route to go. I also used it for my Yamaha as well.

Did the paint hold up after you've ridden it? That's always been my issue. I will admit I don't prep very well. My local pc guy also does sand blasting. That has worked and looked the best for me.

That turned out really nice! do you have the before pictures? As Shawn mentioned, how did it hold after a few rides?

the forks still have alittle polishy haze on them that I didn't get wiped off before the I took the picture. I'll have a better picture down the line, but they shine up nice!

Thanks Shawn, it was definitely worth doing! what's the beer of choice?

I'm a simple man. Most nights it's PBR , if I'm feeling fancy I might get some coronas. But hey for that kind of polish I'll buy you whatever your flavor is!! But if you go to imperial invasion this year I'll be sure to have PBR and RC cola.

I like both of those brewskis! Imperial would be sweet. I've wanted to ride there for a long time now but having the time is the hard part

[Shawn Powell]

Yeah I missed it last year and I'm only 150 miles away. What a bum I am. I won't miss it this year. At least 4 days. Maybe I'll find time to polish mine before than, nah prolly not lol.

Overall it holds good if the process is done right.

Over the years I've found that some pipes take to spray can painting better than others. I'm sure that heat, diameter, location, etc., all have a say but overall prepping is the key.

2 things I've found is important for a better job......one is prepping. That inludes "pickling" the metal. It's a process of etching the metal and that etching promotes better adhesion. Of course all old finishes and rust must be TOTALLY removed and after the pickling process.....contolling flash rusting. The second thing for me is heat curing. I have a radiant heater I got from a customer long ago who was moving.....that I use for heating painted surfaces. Remember reading on the can the instructions for curing the paint?.......30 minutes at 400 then 20 min at 300, etc? Most of use don't have a curing oven so we just start the motor. This usually just ends up incinerating the paint rather than curing it......that's why most flake and chip especially on the head pipe. Even a cheap radiant space heater and a cheapo harbor freight heat gauge is WAY better than just starting the engine.........trying to cure it the best we can with what we have.

Here is a couple of pics of the 90 and the link to the thread over at caferacer.net.

Yeah I think my problem is always the heat cycle. Never done it. Always strip to metal. Clean well. Even used a primer on my 350x then paint. Burned right off. Hence the fiberglass wrap. Looks good to me!! One day I'm gonna buy one of those shiny FST headers. Or a FMF xr400 and have a buddy help weld it real pretty. (My welding is not pretty)
Those pipes look great knappy.

I hear ya.

Even doing the heat cycle to the best of my limited capabilities sometimes it still chips and flakes off. This is when I think it may be a certain bike pipe or configuration or a certain state of tune on the bike.........both of which really doesn't affect PC

Edit post:

Usually failure is seen on larger displacement machines..........maybe more heat? I can't keep a finish on my DR650 for the life of me!!

A few of the powdercoated pieces from Mr.Yaeger showed up Friday night. They look GREAT!

I could not get anything to stay looking nice on my 350x pipe. Even the chrome one I have changed colors.
I finally had one ceramic coated . It's held up for years and looks great.
