I was decoding my 2009 Jackpot serial number decoding and it shows engine code 5vpxb36 which is 78-94 hp/tq compared to the same year 5vpxb37 which is 95-115 hp/tq.
What is the difference between Them.
My bike has victory staggered pipes, power commander v and Arlen Ness air Intake mods.

What difference does it make what the VIN number says it has for HP? Does that change the power at the rear wheel?
2008 and 2009 were the worst years... 100", lowered compression, 1st attempts at closed loop FI...

Here, this is rear wheel power for a totally stock 2008 100".... 75/94

The manufacturer's claimed output is measured at the crankshaft, not the rear wheel. After transmission and driveline losses the crank number drops by up to 15%.

If you really want to know what's up, roll that bike up on a dyno and find out.

Does the lloyds timing wheel make a difference? I am thinking of installing one and set it at 4 deg adv.

You'll see the timing wheel help under 2.5K rpm. I added one recently and it really smoothed it out in the first few gears and seems to make the motor have less mechanical chatter in the low gears.

What did you set it at? I read 4deg and 6 deg. I am leaning now towards 6 deg. I have a PCV, Arlen Ness intake and Victory staggered pipes.

I put it in my 13 Vision at +4. Most Vics take +4 well. See my signature for my other light upgrades.

If you're on a phone turn it sideways to see the signatures under each person's post.
