86-88 DG pipe

[kdx87]

Hi guys,

This is my first post, but i had to ask this. Has anyone noticed the wrong offset of the DG expansion chamber? As in say you were sitting on the bike facing forward on the 86-88 the expansion chamber comes up on your right side and then the stinger goes above you battery and to the muffler, but when i go on DG's website to look at the matching expansion chamber for 86-88 it goes up to the left side where the airbox would be? and the 84-85 comes up on the right side, is it just me or whats the deal here? Also are DG and FMF the only manufactures that made expansion chambers for these bikes? finding an FMF fatty for the 86-88 years is far to difficult here in Australia.

The pictures on the site are wrong.

DMC used to make a pipe long ago. PSI or Krause may have made a pipe. If you can't find an FMF, then don't worry about finding anything else. DG is the only one still made. FMF stopped a while back.

Thanks Jason for you reply

I contacted DG a while ago with no reply, So now if i want to order the 86-88 pipe do i go on the website and select that one that actually says 86-88 despite having images from the previous 2 years? Also any idea on how the performance would be over stock and compared to the FMF pipe? Also i was thinking of combining the DG pipe with the universal FMF silencer any thoughts on this?

Are you able to just call them?

If you are not in a rush, I can call them for you, then report back.

I have never tried to fit the two parts together. Are you talking about the FMF universal spark arrestor or is there a silencer, too? I have seen the FMF universal spark arrestor. It looks nice.

I think it would be great if you could call them Jason, I'm having issues here ringing from Australia, im in no rush, i was thinking that the combination of the universal spark arrestor from fmf and the DG pipe would defiantly wake the bike up. it should also pass noise tests for when i get it plated.

There is a used PSI pipe on ebay.

Thanks heaps Jason,

I'll grab one for the 87 and see how it goes

OK.

I assume DG just has the pictures wrong. They have been around forever.

Has anyone got a video, id love to hear the sound of a FMF or DG pipe?

Old thread, but I just installed the DG pipe on my 87. Looks great and there were some minor fitment quirks. Had to loosen and rotate the rubber isolater mount on the right front of the frame, also there's no small bracket for the rubber snubber the side cover rests on like on the stock pipe. I noticed they didn't quite get the bend in the stinger quite right after the expansion chamber. It does contact the frame but isn't causing any issues. I'm happy with the sound and power though. I had to replace the original pipe after an impact which damaged it.

Loosening all the fasteners to get the exhaust parts to fit is the normal way. I would try to rotate things to get it off the frame if possible. Install a rubber damper or something to help out.

I'm glad that DG still supports these incredible '86-'88 KDX's. They are truly the best air cooled vintage woods bike built. The '82-'86 Yamaha IT200/250/490 (was there an IT465 in '82 still before upsizing it to a 490?) are right behind them, and the Suzuki PE175 Full Floater era right behind that.

I'd trade/sell both of my PE's if I could get a decent '86-'88 KDX project!
