does any one know where to pick up or a 4 to 1 exhaust for a GS550 (1980)?

ALSO
i'm repainting my bike,
I wet sanded the side covers and the gas tank
i then painted the side covers (with Dupi coat) putting about 3 coats down... no drips BUT THEN when i woke up this morning and check them out there where blotchs of like shriveled up paint (as if flame was put to it!!!) the blotches where mostly located at the tops of the side covers

what caused that??????????

right now i'm gonna wet sand down, smooth again, fill in with glazing putty and try again........
 
the paint wrinkled on you, it did it to me too when i painted mine

i think if you get it too thick it will try to dry too fast and wrinkle up like that
 
did you clean it with wax/grease remover and wipe it down with a tack cloth before painting? Sounds like contamination to me.
 
well no, i didn't de-grease it, but the bike was originally red then painted blue... and i sanded down to the red... and little bit threw the red (to smooth out).... and those are the spots that seemed to wrinkle on me... much to my annoyance... this time gonna wet sand, air dry, de-grease, wash, dry, glaze putty smooth'ish, wet sand again, dry then paint :shock:
 
Yeah... its really a PITA. Especially rattle canning it. Hard to make it perfect. But some flaws are just annoying. I painted the brake booster on my old chevy and got orange peel like crazy! And i havent ever really seen orange peel from a rattle can! Anyhow, crap happens.

I say get it smooth, hit it with some primer, wet sand, degrease, blow off with air and wipe with a tack cloth. Shoot it, and let it cure. Hopefully that'll do it.

If not, post back.... with pics
 
Back to your question about the 4 into 1, MAC Performance (www.macperformance.com) makes one for some older Suzukis, at least I got one for my '81 650G four years ago through my dealer. It seemed to go on easily, there was no apparent need for rejetting, and it sounds pretty nice. One big drawback is the chrome quality, however. Maybe it was because I didn't ride much for the last three years, but it got a fair bit of rust and you have to pay close attention to stay ahead of it.
 
My side covers had the same problem, repeatedly..

I started to get the feeling that it was a chemical reaction between the plastic and the paint. i sanded thoroughly and then used a plastic paint and it seems to have worked out fine..

But its just a guess.
 
I had the same trouble on both tank and sidecovers. It's a too-thick problem, as mentioned before.
 
I've had this problem several times at work the problem is related to putting the paint on to thick and quick. The thinner in the rattle can sofens up the paint underneath causing it to shrink up as it redrys. There are really two ways to prevent this. You can put a sealer down first, or the risker option put two real light dry coats on and let them completly flash then put two more normal coats on.

I had that problem...it's your fingerprints!! The oils from your skin will leave a residue..(fingerprint)..use latex gloves..
Hope it helps!:-D
 
ok now i'm just gettin ****ed
I put on latex gloves... then washed my hands (with gloves on).... then wet sanded till baby butt smooth.... filled in with putty.... wet sanded smooth again... rinsed, cleaned, and let dry in a room with a dehumidifier for 4 hours..... washed hands again... sprayed on ONE super thin coat ...left alone....... WRINKLED AGAIN!!!!! :twisted:
 
Echo...echo...echo...

This ain't the first reply like this...I had the same thing happen to my side covers as well.

I cleaned them to a point where I think someone with OCD would find it ridiculous. No love, still wrinkled.

My advice, do what I did. Prime the ever lovin' crap out of them and then apply about a dozen super thin coats.

Good luck.
 
i had to lightly mist mine, let it dry, mist it, let it dry etc etc etc

couldnt even really spray a real coat on it or it would wrinkle
 
so this is what i'm now planning on doing..... i'm gonna throw like four mour coats of retardly thick coats down and HOPE for wrinkle... thats right you heard me.... then i'm gonna bury it in clear coat (kinda like how you bury pin strip lines and graphics) build up the clear coat around it then coat the wrinkles.... then wet sand... spray a LIGHT clear coat layer ....let it cure a LONGGGGGGGGG time and then GO TO TOWN with rubbing compound........ or maybe not

Subsequent coats of paint will only amplify the wrinkles. I dunno if it'll work...
 
thats kinda the idea.... visable wrinkles that you can't feel...... if it looks like crap i can always sand it down again........ haven't started with the tank yet
 
Ok..... so my last idea was a dumb one...so dumb i didn't even try it.....

I sanded down all the way AGAIN......(so sick of sanding) but saw a can of krylon highgloss blue in my garage ....... so i ditched the Dupi color and gave it a shot....... no wrinkles, NOT ONE (I even like the blue better too, brighter) .... now i just have to find more cans of matching paint

also something i ran into, i used up all my old glazing putty and had to buy a new tube....... the stuff out of the new tube (same brand, bondo) ate the paint out from under it and.......WRINKLED:twisted:

Are you using primer?? I didnt have any of these problems..8-[ I used Duplicolor...gotta make sure ir dries for at least an hour before putting paint over it...
Also, look on the labels...I was told not to mix enamel with laquer..
Hope you get it right!:-D
