THAT would be your average STOCK ATV muffler.

Sounds like my "Plan A" from a prior post. I'm not the guy to take up the fight concerned citizens are deeming "too loud" THEY are correct and hold more clout than a track does. "Maybe you should form a riding preservation council" yeah its called the AMA (remember the FREE sound testing kits...

STURD: RE: My first post. A) You need a special non reflective surface to test on. B) You need a totally quiet ambient testing area (no highway vehicle noise, no wind noise etc). NOTE this is what I saw at the SAE test facility. I had the chance to actually go to the "certified sound testing...

Thing is, the 4 stroke exhaust pulse wave is lower than a 2 stroke, the lower pulse wave travels much further and dissipates less than a high frequency 2 stroke. Track set up and having a way to dissipate the pulse is key to keep the pulse wave away from neighbors. A place like Smith Road where...

My first post.

My comments were constructive. "PLAN B" I was making a JOKE about what we are doing at this time regarding sound testing or ways to reduce noise..... which is nothing. MY comments on the photo were based on my experience doing "in the field" sound testing at GNCC's both before and after...

The problem is HOW the test is done as stated above. Im just going by the SAE/EU/TUV/JMCA etc standard for doing the test. (reflection of ambient noise) While I was at HMF we did some sound testing at random GNCC's we also did provide a race support repacking service (for a small fee) which we...

I love that pic of sound testing. Fail #1 No one can be standing near the rear of the machine while testing is being done. (Reflective pulse wave) Fail #2 testing right next to a track with possibility of bikes going by, NICE !!! Fail #3 the poor guy trying to hold the throttle at "X" RPM while...

Here are my findings doing sound testing while at SuperTrapp/Kerker I had the chance to actually go to the "certified sound testing lab" at SAE to do testing on an exhaust we made for Indian Motorcycles where we did static and drive by testing. A) You need a special non reflective surface to...

IF it has a good crank/piston/ignition I would love to restore it N/C and return it to you.

Yeah the Ribi Quadrilateral were some neat forks.

MAN I like that little bugger BUT, Classic 125 (IF they still allow the SL150) the SL 150 would eat it alive. I had the one guy pass me WFO in WVA on a 150 while I was on my CR125 and I know my Elsie was no slouch. I would LOVE to restore that Deek though, how much?

Doesn't he play for the RED WINGS??

Or Pontiac Silverdome Amateur SX

Or raced at Norwalk

Old invoices from cool places.

Or had a dealer parts discount card.

When was the last time you got a Christmas card from your bike shop or track?
