• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

TE/TC Inside scoop FMF "long" Jarvis muffler

for sure, the silencer on a two stroke is just an extension of the stinger. longer tends to choke down top end and limit rpm, but boosts bottom and mid. cutting down the silencer usually does the opposite.
of course there are exceptions, where you have a very restrictive muffler and replace it with a different unit thats shorter you may gain everywhere. its just kind of a guideline. changing silencer length with everything else equal is definitely a tuning tool..

This is what I was talking about but didn't explain well, if at all (Ty justintendo). The longer silencer will cut the top end, therefore making the low and mid seem stronger and consistent. However, a shorter silencer will actually produce more power everywhere due to the decreased back pressure and wave form propagation in the expansion chamber. If you look at either of our race bikes, you will see very short silencers. These are custom made for us from Procircuit to develop the highest hp throughout the powerband.
 
Got to love my boys at FMF I called up and asked about the new longer turbin core spark arrester silencer I said do you have one for my OLD Italian Zip Ty Racing CR 300 Well look what I got last night. You can see the difference between the original FMF Silencer and the new one Now stay tune for a test

I wrote the date on it because I just cleaned it rewelded the tabs and installed new packing, it is ready to go. The date is so I cam remember when I serviced it. I will race with the short one this weekend as I have no time to test the big one. Then next weekend will compare both of them in different types of stuff and do some high speed and slow stuff

^his sag numbers must be way out!:eek: thats the q-stealth hey ajax? i bought one coupla years ago, crashed a few times & bent the subframe silencer mounts(too much leverage, too weak mounts). chopped mine off just in front of the rear mount, binned the SA & now have a shorty! BTW i got another under warranty as the seam near the front mount cracked/split both sides of the mount-like 2" straight line 'split'!
 
My buddy has that same silencer on his WR300 , he has had to weld his sub frame muffler hangers up twice since he installed it. No problems in 5 years with the stock one. I think it stresses an already suspect subframe.
 
they dont build em like they used to. maybe they should just add 2 lbs to the bike and make subframes strong??

Unfortunately people would look at the spec sheets and not buy it because it is 2 pounds heavier. Careful what you ask for. We get semi frigile bikes because we yell about weight. We also get bikes missing cool stuff the older bikes had like axle pull handles, Zerks, re enforced subframes, skid plates, and lots of other cool extras.

youre preaching to the choir kelly! im content having all that stuff. easy to remove it all as well. heck, all my bikes have the stuff you mentioned. lol, funny you talk about axle pull handles. i didnt know they quit putting those on bikes! i was wondering where those were at when i look at newer bikes. i would weld them on, i can tell you that.
 
Its too bad the manufacturers cant claim a "naked" weight and then put all that stuff back on. Cma.
 
Looks like the long silencer worked for MXA's TC300
As well as my brothers 250SX with a 300 kit
More overrev with the stock silencer compared to the PC shorty
