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 The previous version was outdated and no longer supported.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

I haven't played with the TPS too much yet, just enough to make the backfiring go away.
Roughly 420 total miles on the bike.
I've got all the extra emissions garbage off it and in a box in the garage
..installed the titanium and carbon fiber exhaust rather than just popping out a screen on the stock can because the blue FMF looks better
but to get to the point, this bike HAS to have more top end power then mine currently does!
I know the air intake is very restricted by the tight composite airbox, and I (guess I) dont mind cutting holes in the cover/sidepanel if it's well accepted and recommended.
(Three 1" holes along the top of the panel seems to be most common, although I read somewhere recently that six or seven is the magic number)
I would be using some type of oiled filters, not just a riveted mesh screen I don't think.
I'm just trying to dial things in. I don't (really) want to run it clear up to redline but what is redline on these bikes anyway?
My guess is they should hit a limiter around 10,500 rpm.
I'm sure it's a safe 2-3k away from where it could be and peak power is probably made around 8-9k rpm.
It can't be where I was though, chugging along with stock gearing in fourth gear.
Noticed today while working on wheelies that the bike really cuts out above 7k (my guess, she's starving for air).
I know I REALLY need to learn to shift on one wheel lol but I'm guessing on the exact RPM because the display lacks a Tach.
BTW I'm at sealevel or riding within a thousand feet of it 90% of the time and run 91-92 pump gas with octane boosters and ethanol shield type additives almost every tank.
(best I can do in CA) Thanks for reading all this, look forward to reading the replies! -Tyler
 
500's have more bottom end
350's have more top end and 450's in between, you can't have it all.

a big bore needs to be ridden like a big bore, revving high isn't the answer.

what map do you have?
what gearing?

you also don't need a tach, you should struggle to check speed let along what the tach says.

i drilled holes in the side of my 501, added a 13 sprocket and it rocks
 
I hear you bowser, i guess im just used to the powerband up high that my 06 SMR510 produces.
I'm running stock gearing on the 16'.. 15 or 14/45 i dont remember, and I've had the Euro map loaded but not tried a map switch or mild/wild plugs yet
I'm thinking of bumping up the rear to a 49 but that would require a longer chain i do believe so its far more economical to drop the countershaft sproket to a 13tooth although i've read when researching gearing for my SMR smaller is worse on the engine up there, more front sprocket teeth=more engine longevity for some reason i don't fully grasp yet (slower/less spinning probably)
 
i'm using 13/50 and don't have the lack of top end like you. I was going to drop to 52 rear next
