Need dyno tips on bigger T.B.

[tireater]

Got my 55mm throttlebody from H.P. inc. for my 103" WT26 cam build...
I hope I can get it together and on the dyno Sat...Any tips for tuning the SERT...?

Yep
Let the dyno tuner do it.
Be sure the motor is not using oil and has normal leakdown numbers 1st before wasting the money on a configuration before it is sound and stable.

YOu got the grooves, don't you?

One "tip" I can give you is to make sure your tuner tries some low timing/lean fuel scenarios while he's got it on the dyno.
It may or may not help, but often the grooves do respond to that.

The dyno guy took alot of fuel and a little timing off my 05 FLHT to get it to run right...PC3
On my 06 St Bob... he said it had the right AFR w/o adjusting the SERT...
This time we only are adding a larger T.B. and hopefully not having an oil leak...
Both my bikes run up to 40 mpg with the grooves...I still get 30 extra miles per tank on the bagger...

Check the rear tire pressure and run one with the A/C off to see if you have a big enough one on there

what kind of heads do you have on it

I concur...  Max

Where you taking it for tuning?

My Garage in Ventura...They have all my previous runs on file...45 psi in rear tire...I'm pretty sure the Ness BS 2 is big enough...
I'm sure my bike was the first they tuned with grooves...I think they are still in 'learning curve' mode... (me too)...
