I'll start
42 before tune

50 after

heres the curve

ESR 310, ported by Nate
LRD exhaust LED SA Silencer
39mm Carb
Vforce 3 reeds
Ebay intake
Advanced timing

Heres a vid for fun

Why did the dyno guy compare power and an air/fuel curves using dyno runs made in different gears? The length (time) of the dyno runs between 5th and 6th gear can be enough to change the shape the power curve. Did the dyno guy remove the sniffer tube from the muffler after he was done tuning and make a few more runs to check and see how much the sniffer tube could have been affecting the power and piston temperature?? Most engines need to be richened slightly after removing the sniffer tube and reducing the restriction the sniffer tube adds.

Do you have the run files from the dyno? Not pictures of the dyno sheets but the actual data files that are on the dyno computer. If so, send them to me if you want me to look at information that could possibly make it run better and or more reliable.

You know Jerry I have no clue why he did it that route & why he only threw in one main jet & called it good. I know if he would have spent more time tuning he could have sqeezed more power at it. It still runs like garbage, worse actually. I Know hes mostly a 4stroke guy & probably knows nothing when it comes to 2strokes.. I had my dad drop it off to him & dad picked it up, the fella said it was good to go.I was watching Arlen dyno some 250r's & it looked like he did it way different. Hmmm

Going for another run had to fix some issues

My 2014 version of a stock 250r

My buddy's ESR 420 with an oof pipe, 40.5 keihin, cr ign, trx11 port... He was somewhat disappointed lol. He was told should be about a 70hp motor.

My old FTZ built pilot cylinder 390, 40.5 keihin, cr ign... The tuner said "something doesn't seem right" lol. I shipped the motor back to FTZ to have the. Check all port timings etc... They said it was fine. I switched the carb over to a 44mm Lectron and it did run better but still was a disappointment for how big the motor was. But it had torque like a train at least...

Here is my 363 Sphinx on Alky(with Shearer OOF) compared to 110(trx5cm)

Rupp250 · « **Reply #10 on:** May 07, 2014, 10:02:53 PM »

One on Alky & OOF, other 110 and TRX5CM

Bigred · « **Reply #11 on:** May 07, 2014, 10:19:27 PM »

Rupp looks like a big improvement

Rupp250 · « **Reply #12 on:** May 20, 2014, 03:31:01 AM »

Any more out there?

Would you display the time VS HP graph of the above runs?
