I "feel" like I may have lost some torque on my Raider. I don't know this for certain. It's not sluggish by any means but I'm not feeling that same rush when I pull on the throttle. I put new plugs in, new air filter and tires, oil change and gear oil changed. I've got Vance and Hines 2 into 2 Big Radius pipes with a Vance and Hines fuelpak. It's running fine. Maybe I'm just getting used to the bike. I don't know. Is there anything else I should be looking at?

Its a very subjective thing.

When I owned air cooled VWs, I knew a super beetle had a flat out level ground no wind top speed of 82mph.

After I did a tune up, there was a country road where I could take the car and hold the pedal down. If I got the timing off or something else was not right, it would not hit 82mph.

I dont know if you could do something similar on your MC - its so freaking fast - maybe a 0 to 60 acceleration time, or track your mpgs to see if its not running right.

The only suggestion I have is run some SeaFoam thru the bike, you might have some varnish in your injectors.

I should change my username to MrSeaFoam

I just did an experiment with my VS650 - I decided to run it on ethanol free regular gas and see if I get better mpgs. The bike seems to be running better, smoother, and cooler (the heat I feel on my pant legs when I stop for a light)...

but I filled it up today. The last tank of 10% ethanol I got 58.5mpg

with this tank of ethanol free gas, I got 58.5mpg - exactly the same, under the same commuting riding conditions.

Even though the bike 'seemed' to be running better to me, I think it was all the placebo effect. If the bike is getting the same fuel-mileage, I dont see how one fuel could have better fuel density per gallon than the other, when it did not show up at the pump.

Maybe the bike is running a little better on the ethanol free gas - maybe Im getting better acceleration, resulting in me riding a little faster all week, which made the fuel economy wash out?

But the bottom line is, the seat of the pants feel is very subjective.

Regular ethanol blend is about $2.80 here. The ethanol free gas is $3.50 If Im going to pay $3 more per tank, and have to drive to one station to get it, Im going to need more than a feeling.

My last 2 fill ups were 92 and 93 octane. I've got 91 octane in the tank now. I wonder if it likes the higher octane and I'm feeling the difference. I'm a Seafoam fan but there has to be something better for the injectors than that. I did read that the only way to really get your injectors clean is to have them removed and done professionally using some vacs or something.

Maybe you have just gotten use to the torque. The first few times in my go fast cars and bikes my stomach would be left behind me the first few times I nailed it. After a few more times the torque was there but I got used to it. Just an idea as to what it might be as you stated it still runs good. If you figure it out let us know.

Are you getting pre-ignition or detonation on the 91 octane? I'm willing to bet that you're just getting used to what the Raider is delivering.

Sounds like you are doing all the right things for the bike. I am betting it is a seat of the pants thing.. UNLESS the fuelpak is not working. Make sure it has power. I would recommend an Ivan flash and do away with the fuelpak. Just my opinion. 120tq and 92HP to the ground with Cobra Sweep pipes. Not the better 2 into 1 like you have.

LOL Yea.. Damn that is a lot of bike to handle though.. LOL
Yes, I think it's insane, but moto vloggers seem to like it. Few reviewers said that handling is not bad when it's rolling. I'd be curious to try it out.

IMO OP just got used to the torque feeling. I experienced the same with my Stryker - it seemed to be super strong for a couple of first months I had it, but then I started noticing the lack of torque at lower speed and a lot of jerkiness. My plan was to send the ECU to Ivan, but I traded it in. OP should really consider doing the flash - almost everybody likes it as it fixes a lot of issues of the stock map.

I get some popping on deceleration but I attribute that to the pipes. I rode this morning and was purposeful when snapping the throttle. The torque seems to be there. I think I've just smoothed out my riding style. It may be a lazy wrist issue.

Where you shift the bike in the power bands makes a huge difference.

I seem to remember you want to upshift when the engine is at or just past the HP peak in the curve

and you want the engine to land in the peak of the torque curve when you let the clutch out in the next gear (a function of the gear ratios).

Unless you are looking down at the speedo or a tach each time you shift, that can vary quite a bit, and it makes a big difference on how much power and torque you get from the engine.

For doing 1/4 mile times at a track, shifting at exactly the right instant in each gear is everything.

BTW, this is one of the reasons I like having the stock exhaust on my bike. If I feel like it I can take off from a red light or stop sign, and get on it WFO up to 60mph, and not really attract attention to myself, because the bike is not roaring like an aircraft taking off from the runway...

Agreed. I practice something every time I ride. Right now I'm working on shifting clutch management. My bike likes to be shifted quickly. I've been riding over 25 years and still learning technique across the board. I am getting really comfortable with the Raider. It's a good fit for me.
