EXHAUST CHANGES PER YEAR


EXHAUST CHANGES PER YEAR

Postby twinegar » Thu Oct 22, 2009 12:30 pm

Did Honda use the same exhaust on the 79 and 80 or were they channeled differently inside for 80? The reason I ask is that my 80 sounds more like a 12 cylinder Ferrari. Maybe my 79 needs some valve work but it runs smooth as silk.

The exhaust for the 1980 was changed to adapt to the changes in valve timing. It is less restrictive than the 1979. The part-number is also different, indicating it is a different item.

Would a welder be able to cut the #1 header pipe off at the bottom end near the shield and weld in another one? The is an 80 left side exhaust for sale that has a mashed area and because the 80 exhaust is different from the 79 I am thinking about grabbing it. Opinions please!

Double wall may pose a problem I would think but may be possible...

Ebay 290363166503.
Should I wait for another to show up? $100 seems a little steep.

Any thoughts on pouring Rustoleum in the muffler to coat the bottom third and them pour out the extra? The area where the muffler welds to the down tubes is swelling but not through the chrome yet so maybe sealing the inside would extend the life a bit. A drain hole will be drilled also.

Not sure what the temp range is and I only mention Rustoleum because I read it here someplace. I had considered using liquid tar but again am not sure about the temp but it would probably smoke some at first and then lay down a gooey coating that would keep the moisture off. I read that Honda coated the inside of some of their exhausts with some sort of asphalt and it got me thinking. I was hoping I would trigger a discussion and someone would know more about it or had done it successfully.

I am definitely going to try something. I think tar would work considering how hot it is when they apply it to a road surface. I doubt that a bike exhaust at the muffler gets any hotter.

Tar would work for sure but until the "light ends" ( volatiles) had flashed off, there would be a possible risk of fire... Something akin to a chimney fire.. :?

I like your train of thought though... :idea:

I would think that tar would be problematic on many levels . . . . on top of everything else, it would STINK

I'd find something better than that - Perhaps a paint marketed for barbecues? I'd try the Rustoleum before I resorted to tar

Kreem makes a ceramic-based liquid I've used to coat the inside of my Ironhead Sportster pipes to eliminate any bluing. Easy to use and it appears to be very effective. I'd imagine it would prevent corrosion as well.
