  • 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 The previous version was outdated and no longer supported.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!

SMR511 Intake Snorkel

Has anyone removed this piece of rubber from above the right radiator?

It seems as though it restricts airflow more than it enhances it.

Thanks.

I ran into this when camming a Harley motor:

High HP cams have a large amount of overlap, where the intake and exhaust cam are open at the same time. The snorkel on the intake and the amount of baffling on the exhaust work to create a "balance" where the air/gas charge is suspended in the combustion chamber while both valves are open. When you remove the intake snorkel, you will need to remove a corresponding amount of exhaust baffling to try and maintain the balance. Altering the intake and NOT the exhaust will typically induce intake pops and backfires, as the air/gas charge will want to migrate back into the intake.
 
many have modded the airbox or put the TC lower section on and report better performance. I am leaving mine on because i love how clean the filter stays and think this has something to do with it plus my bike has plenty of power for me.
 
Hmm.. If I were building an SMR, I'd chuck the whole air box and put in the biggest K&N tornado I could fit. I would place sheet metal around the radiators to deflect the hot air. Port & polish the head, add TC449 cams, PCV, iridium spark plug, FMF MB TC header, header tape + 4.1...

But I'm a slow poke and enjoy clean filters. :)
