Topic: pin holes in stock exhaust system. Solution?

[gregwaits]

My K8 still has the stock 4-4 pipes. In general, they are very clean in appearance with no dents or rusted through spots.

However they do have numerous pinholes throughout. When the bike idles, you can see puffs of smoke occasionally.

Are there are fixes for small holes like this? Or am I a doomed to see the pipes slowly go to seed?

I had 2 pinholes in my HM300 pipes last year...fixed it with JB Weld...and its held up over this last year (+3500 miles).

Good luck

Thanks Andy 

I have a couple tubes of that in the shop already. Worth a try!

if you have pinholes... they are probably pretty well gone on the inside as well.

not that they can't work for a long while to come, but yes, they are probably on their way out.
