Best mods I've done...919

I saw a bike at McDonalds one morning with every aftermarket mod you can imagine. I asked him what was the single most noticable mod. He said Royal Purple oil. I can't tell you how hard it was for me to spend $64 (plus filter) to change my oil. He was right. I can feel the bike nudge from my turning the throttle slightly when the wind gusts push me. Yesterday I installed the Power Commander, and took it for a test ride this morning. (40 miles) It runs as smooth as a sewing machine. The shifting, take off, has never been so smooth. I haven't hammered it yet. I have a 17/41 tooth sprocket set to keep my RPMs down on the interstate, so obviously I haven't been concerned with torque. I'm going back to the stock 43 tooth back sprocket because it really didn't seem to help the RPMs, but it very noticably lost its kick. I'll let ya'll know how it turns out.

I heard Royal Purple gives you like 59hp at the wheels and is more efficient than adding turbo.

search oil and you will find 18929473982928 threads on it..

I never did like the idea of pouring in clean oil dyed so it looked dirty in the sight glass right out of the bottle.

This is an interesting one. I've run 3 different ratios now - stock [16/43], then 17/43 and now 17/44.

The 919 conundrum is that changing the gearing certainly does move the revs, but the instruments won't show it. The speedo picks up its signal from the countershaft sprocket, and the tacho gets a signal from the electronics in the engine, so they are locked together - only a change in internal gear ratios will alter them.

What does change is the rate of acceleration, which you have noticed, and the speed of the vehicle across the ground, of course, but a GPS would be required to show it...

So when 4000rpm is showing around 64mph on the speedo with stock gearing, your 17/41 change will give you 71mph at the same engine speed. But because the changes are made after the countershaft reading is taken, your instruments know nothing about it, and still show 64mph @4000...

[Check the excellent gearing spreadsheet at 919.org 919/Hornet 900 Owners Group to compute various changes.]

I'm running a 16/45 in 520 with aluminum rear, and it all combines for a very noticeable difference. I'm at 3500 ft, so engine power is down about 12 % from sea level. I'd be running a 16/44 if at sea level. I used a SpeedoHealer to correct the speedo. I used the same spreadsheet, it works nicely. I used the one from Sport Rider for the drive force thrust and shift points calculations.
