Ya got a 4" grinder ?....get a cuttin wheel and some Harley clamps...then visit any auto parts place.....ya can put it together w/o doin the welding....cut to length...make a longitudinal slash cut, add the clamp....its just not as reliable....I did that a few yeras back before Jack "loaned" me his welder....

But if ya fab it up....and bring it to a local muffler shop...theyll do it for ya fer near nuthin.....thats gravy fer them....off the vehicle, etc.....$40 mebbe ?....its worth it in the longrun.....

kagaku I did the degoat when I replaced my stator this past weekend, but noticed the following..

1. What do you guys use to seal the gaps between flex pipe and rigid pipes under the clamps? I'm noticing a lot of air coming out of these seems.
2. My front exhaust is extremely loud.. Almost no muffler loud. Not sure if it's coming from the exhaust manifold or the exhaust itself. Here's what I did:

A. Unbolted exhaust manifold nuts (4) from cylinder head. Pryed it loose, but didn't remove.
B. Realized I'm an idiot and don't need to do that. Put the nuts back on as tight I could.
C. Removed the exhaust pipe nuts (2) and the clamping mechanism.

After I replaced the stator and reassembled, I did the following..

A. Put a new kawasaki crush gasket in place
B. Put exhaust pipes in, along with the two clamp pieces and the cover
C. Put the nuts on, tightened them up

I'm definitely noticing a raw exhaust sound from up front, but not in back. I unbolted and rebooted the exhaust on (but not the manifold, can't get to that without removing radiator), but no change.. Do I need more than one crush gasket? These seem small and thin. Is there some gasket on the exhaust manifold that I need to replace now that I've sorta removed it? Am I missing something else?


3. Never noticed, but one of the PO's took off the right side heat shield. Not sure how I missed that, but sure enough my right side looks terrible now! For now, at least.
4. Finally.. tons of backfiring while decelerating.. gotta readjust the fuel ratio I guess. I've ear shaved and rejetted, so must just need to adjust.

OleDirtyDoc You didn't earshave so you should be fine.and every bike(as I've learned from the guys here)is different so what works for one bike might not work for another. best i can say is to read your sparkplugs.others will chime in
