Topic: New Delkevics are up, opinions?

[700504]

So I'm still beating around on my 1978 cb750k and I see that Delkevic just put up 2 new models for 77-78. I know everyone's been saying that there is no re-jet required, and these two new models say the same in the description. I'm just wondering if there would be a difference between the two; one is like a kerker styled megaphone and the other is yoshimura styled straight. Do you guys think the yoshi styled would require a bit of jet fiddling?

Nice...  As far as jetting goes, It will depend on the baffling, If Delkavic says no jetting changes they must have quite a restricted baffle {quiet}, thats not a bad thing as its easier to modify a baffle for more flow than it is to make a more restrictive one...

I believe the baffles to be 2 stage so you can make a little more noise/HP.

Cool, good value pipe...

I just ordered one for a 550 with the straight exhaust. Gonna see just how choked down it is with their baffle and then decide what to do.

Nice, I'm actually hoping these turn out to be a nice smooth flowing exhaust, that's not god-awful-loud at the same time.

Chocked down is probably a bit harsh, I think "Legal" is the word you were looking for....

Legal schmeegal.  I like it when these bikes roar instead of whine.

Lol, "smooth and crispy" is the exhaust note most pleasing to me 

Either way, I'm willing to bet that the straight through exhuast has a bit more growl than the megaphone.

If it does not need rejetting, you wont be gaining any power.

I'm not really concerned with that, I have a 78k so I've already bored the pilot jets one step up to get rid of stumble from idle. I'm currently running a Jardine style 4-2 with turnouts. They are just a bit loud and I'd like something more quiet and smooth, not looking to make a racer out of the bike. So avoiding any further rejetting is the key to me picking up one these sweet headers.
