Dyno time!

Finally got a chance to get her on the dyno! How did the old girl stack up against yours?

I thought so as well. Did you do Eriks flywheel lightening? I was wondering if maybe that's why.

OE flywheel. I did carb stuff about 10 years ago and I can't remember what's in there. Before carb work/K&N, it did 108 on the dyno. Before this run, I installed the JF fuel screws and cleaned my K&N, reset TPS. Bike ran perfectly all that time before but now it's unhappy below 4 and my a/f plot shows a bit lean. So some tweaks are in order.

I'm the same. OE flywheel, K/N, I have velocity stacks, Flo commander, I jetted and my a/f is good. TPS. I can't imagine what the 15 hp difference is?

I use one of them Eriks flywheels ...LOL
Flywheel weight does not effect Dyno numbers as far as false or different readings. I have done back to back pulls , same day, same part of the day with and without light weight flywheel ...numbers were consistent with only the normal error range anticipated

Dyno to Dyno results comparing are all but useless. Machine, calibration, operator, altitude, weather all effect the outcome.

Yep, I do agree. That being said, in '08 bone stock with just a slip-on:


108ish on a 2 up completely different dyno, different software, yadda yadda.


Then one month ago, my VTR was ran on Koups dyno. I did some carb tweaks not long after the run in '08 and changed to low mount D&D. Only 2 hp difference which seems very realistic.

We will definitely be talking soon more about those flywheels. LOL

Well I just can hardly imagine a 15 hp difference between dyno runs, but I guess it is all down to color now...LOL

Id like to make a few pulls on the local dyno here but the guy wanted 100 bucks for 3 pulls.
Ive done car dynos for 30 bucks for 3 runs before! is 100 bucks about what others are paying for bike pulls?

This one was at a local bike club event. The guy had a dyno in a trailer and was charging 40 bucks(Canadian) for three pulls.

I thought I was at the after! LOL Like most of you, I have been plugging away for the past few years, K/N, jetting, TPS, velocity stacks, Flo commander, R/R, Jack Flash fuel screws, manual cct's, the list goes on.

Guess I will have to go more drastic...

Have you a before & after dyno chart/s from when K&N was fitted and rejetting?

PS Here's a variety of dyno runs from the UK VTR forum > https://www.vtr1000.org/phpBB3/viewforum.php?f=36

Well I don't pay for Dyno time as I machined the parts needed to install the updated sensor package..

The shop occasionally has done Dyno night in conjunction with bike night..it was billed as a HP shoot off, but stopped doing it due to liability. even with owners signing a form and having to hand write in their upper RPM limit they were willing to let it rev to.. A few blown up bikes, few broken bits of plastic as we hunted for the hook up locations, or later lost fasteners they claimed we did not put back or tighten and hurt feelings made it unpopular with the shop owner.

Dyno time at that shop is $250, but its not just a few pulls, its all the adjustments that can be made on your bike in that session. Power commander guys get the best bang for the buck on the deal, carbed guys the worst. Dyno operator has been know to break up the session in two parts though, a run, send bike and owner home to tinker, and another session later

You are definitely missing some HP and the torque output shouldn't drop. Do you have the AF plot? If I have to guess the AF is too lean and the carbs need more juice->bigger jets.

This is mine with Dinojet/K&N (old version)

My dyno time was $5. The local Ducati/Kawasaki/Suzuki dealer has an open house once a year and the dyno is free. They charge $5 for the print out with torque and a/f.
