'Belle's 748 Fix-up

[Speeddog]

I bet it didn't break 100HP, unless the motor's over 800cc now...

[enzo]

It's an 853 with a power commander.  Should we start a pool?

[mostrobelle]

I forgot to ask what the HP read as, but it started out on their dyno at about 90 hp.  Scott said that he could get a few more out of it, but I'd guess it doesn't break 96.

The torque output tells a large part of the story. Those are the numbers I look at.

[mostrobelle]

Torque is in the low 50's.  Nothing to write home to mom about, but enough to have fun with.  I don't particularly give a rip what the engine can do, because it's still me riding it.  I could be on Rossi's bike and my laptimes would still suck.  As long as it's smooth, I'm happy.

Keep in mind the dyno at Desmoto (Double Dog's dyno, actually) is an inertial dyno, so the numbers will read ~10-15% lower than a "standard" dynojet style dynamometer.

Desmoto told me that there's a huge +/- with any dyno numbers, but yes, theirs reads lower than a dynojet.  I'm really just looking at the curve and where the changes happen in relationship to the numbers.  The numbers themselves aren't that critical. 

[tigre]

agreed... numbers are generally not comparable from one dyno to another.  I saw the discussion about the pool for whether it will crack 96hp and thought I'd call that out.

[mostrobelle]

Good point.  My guess was premised on an earlier run on that same dyno. 

[tigre]

ok.  yep.

I'm curious where my monster netted out on their dyno.  I was so overjoyed by how smooth it was that I forgot to ask!

[mostrobelle]

I thought you were tossin' out numbers all over the place.  Now that I know that you don't have it on paper, I'm going to tell everyone that heap of junk ran at 35 hp.

If we're getting into numbers envy, please keep in mind I've got an 1198R* with kit cams + velocity stacks, ported heads, and several drums of MR-12 waiting to get mapped.

*true... it started as an "S", but when I replaced the complete heads (including cams/valves), rods, crank, and swapped the rear shock for a TTX, it became an "R"...

You're too easy.

Thats cool n all but its still painted like a tiger.

Good point -- it's an 1198GRRR
