Thanks. I was looking at that but wasn't sure that would have any effect. If you think it will improve that sound, I'm in.

Could the restrictive stock airbox be causing any of this?

 

If you're talking about a whale farting sound when you roll off the throttle to switch gears, then it's the PAIR valve not the airbox. A stock airbox doesn't make any sound, at least mine didn't. Did you check it recently? Maybe a mouse made a nest in yours and it is restricting the airflow, don't laugh, happens all the time

 

Whale fart... Love it! Much better description than my catfish. Thanks for the laugh!

Yes, I've recently had the airbox off and it's clean as a whistle. (Cept a tad of weep from the crankcase line.)

I was thinking stock airbox like it might be "asking" for more air.

Oh btw, is it still possible to get the "block off plate" for the desmog? The links in your write-up no longer connect.

Thanks again for the help!

 

I was wondering about the plates also as I have an interesting in doing the desmog. I searched the Honda parts website referenced in the article but didn't see them.

Anyone know anything about those plates?

Awesome thanks fastspek! Ordered...

 

I appreciate the info (and warning!). I would definitely have been wondering if I didn't see them (or hear back) in a week!

 

Mine only took a week, but maybe I was just lucky..
I got the polished stainless with dimple.. Great product and I'm very satisfied.. :thumbup:

 

Yeah, I forgot to mention dimpled or undimpled.

 

What is the dimple for?

So you can keep the reed valve intact. I still recommend using high-temp RTV tho.

 

The dimple saves you 5 min. from removing the screw & reed. It only fits one way. BTW, re: pipes: IMHO, it's better to be HEARD than NOT seen!

 

When you do your desmog, go ahead and remove the snorkel and flapper valve thing that is attached to the upper inside of the back of the box. You will see it in the write-up on bares site. It opens up a good size area for more air flow. Also, consider rerouting your crankcase breather to an external universal type breather filter. This eliminates any oil accumulation at the air filter. Just be sure to cap that nipple on the backside of the airbox.

 

Sweet. Parts showed up in a week. Guess I know which project I'm working on this weekend. Ready for the rain to stop. 11 straight days. Up to about 6" so far.

 

Finally got to this project. Did both desmog and sas removal. Man there's a lot of stuff that came off this bike. Great walk through on Bare's site! That rear reed valve assy was a bi.ch to get to.

Happy with the results. Don't hear much difference in sound except bike does seem to run smoother. Question: is it normal that the bike would now run at lower rpm? Not complaining, just wondering. I don't THINK I hit anything that would have caused that...?

Also, "whale fart/catfish sound" is still present on decel. It's not a popping sound. I can live with it but, if there's a way to eliminate it, I'd like to...

 

Ok so I picked up a used set of pipes through classifieds here. Took off the stockers and guess what...no crush gaskets and the studs in the rear cylinder were loose. Almost put the stock pipes back on to see what a difference that would make (after tightening and installing new gaskets) but...naaaaah! On with the new pipes...! Anxious to get her out in the morning for a test run.

Pumped...

 

I've never had my pipes off so no personal experience.
Many, many words have been written about the crush gaskets don't appear to be there but they really are.
People use a pick or something small and pointy.
If you search this site you'll find some posts.
