That they are!  Brand spankin new! :) :)

I finally had enough spendin' money to get a set, and I knew Jerry would really appreciate it considering he tends to be the one that ends up behind me on longer group rides! ;D ;D

The pipes are still fairly loud, but the baffles take out the harsh high note that they used to have.  That's a good thing considering I park on the 4th basement level of a parking garage at work.

I couldnt agree more Gordon -new baffles make such a difference to the pitch of the HM300s...I changed only 2 over and it was like night and day.

Have fun and good riding!

cheers

Thanks, Andy!  I only hope they don't screw up the very delicate balance I've managed to strike concerning the fuel mixture and my carbs at high altitude. 

I have things set almost perfect, if just a tiny bit rich (but don't all these early 750's run a little rich), and I'm afraid these new baffles are going to mess that up.

Gordon,

While my 750K4 runs rich the K2 was running very lean here are sea level..until I changed the jets out for 120s -now its just right...the recommended 110s (for the K2 carbs) were really lean...so its going to depend in needle clip position as well.

Anyway I am guessing you will be fine though worth checking after the next ride...I find that #2 (on both bikes) runs a little leaner....and not really sure why all other things being equal.

cheers

Thanks for the reassurance!  I'm just worried because it took me several months of tweaking, after moving from near sea level in Oregon to mile-high Denver, to get the 750 to run right without fouling out the plugs.  As it is they keep a nice, milk chocolate brown to them most of the time, but I'm afraid the addition of baffles may tip the scales toward dark chocolate or burnt coffee. 

I'll just have to wait and see, I guess. :-\

Updates please after your ride a bit with the new baffles! Ill be curious to see how you get on...

Ive never had a problem running at altitude on my K4 (since it is running rich already I guess this is the reason) - usually though it was only passing through somewhere but...riding from LA to Grand Canyon (at 7000 ft) then to Colorado (10,000 feet passes) I never felt like the bike ran poorly. Also when riding through Mexicos Central Highlands (6500 ft) after having come from the coast - again no issues...and when I went to the Alps and passed through some 10,500ft passes no problems....

I was running a combination of Mac 4-2 (Mexico trip), aftermarket 4-4 (Alps) and stock 4-4 pipes for X-USA trips...all at 110 main jets, stock airbox, stock filter....never played with the needle clip position but think its in stock position (2nd clip?). Maybe your older 71 is a little more temperamental.

Anyway good luck with it.

cheers
Andy

The K1 has 120 mains and 40 idles stock, so it's on the rich side to begin with.  To get things back to a good mixture after the move I swapped the idle jets for 38's and put in a UNI foam stock air filter replacement, and did some extensive tweaking with the idle mix screws.  It's never had any issues at higher altitudes, even up to 14,000 feet, other than the expected loss of high end power.

I'll let you know how the plugs look after riding around for a while with the new baffles.

Gordon,

Why are you yelling so loudly? Can you speak a little quieter now? By the way I meant to say thanks on the ride for pulling over. 

Guess I felt guilty about my bald tire. I do have a tire like yours with tread......hanging on the wall.
