17t sprocket makes this bike soooo much better.


Recommended Posts

I love the VFR.....but it had some things about it that I didn't like. The gears are too short. It bucks at low speeds without precise throttle control, and engine braking is a bit extreme.  Also, the speedo is off by at least 10%. I opted to change my front sprocket to a 17t. I put on a new 110 link x-ring chain and rear 43t sprocket. 

I was able to hook back up the flapper which gave me back the low and mid grunt I was missing. 

It brought the speedo close enough to actual speed. 

It makes the gears long enough to cut down shifting in town in half.  I am able to stay in lower gears instead of shifting to a higher one. Less shifts up also means less shifts down when coming to a light.....also nice. 

got rid of a noticeable amount of bucking.

engine braking is not annoying anymore. 

did not notice the loss in acceleration at all. In fact this thing still hauls ass at will.  

 

I realize that this is going to irritate some, much like oil and air filter talk, but I just wanted to share my experience. 

 

thanks

Joel

Bike is totally fixed and love the 82lb clutch springs.....

i hear ya with the on/off throttle, it doesn’t have the forgiveness of carbs. from what others have said, the PC3 (spelling?) can soften this. i have all the slack out of the throttle cable(s) and it still requires a very light touch. one thing to keep in mind is to make sure you aren’t putting any body weight on your hands, this makes light control input more difficult - like blip-to-downshift.  

personally, i love the engine braking but i do dab the front brake lever to turn the brake light on to warn. 

 

what have you noticed in mileage change with your sprocket change?

I was getting about 40mpg average.....just dd the change so I will see what a few tanks does. It is likely to stay the same as I am in a lesser gear to avoid changing up and down to 3rd or 4th. I am now mostly 2 and 3rd.

thanks

yes I weigh 225 pounds so I squeeze the tank with my legs regularly to take the weight off my arms.  I have seen no negatives from changing the sprocket. Didn't think 6.3% change would do much but it is very noticeable. 

thanks

Don't forget that now your odometer is off, so take that into account when you figure your mileage.

yeah, I read somewhere that the odometer is accurate but the speedo isn't. 

thanks

Yeah, norm from the factory, speedometer is 8%-10% fast and odometer is spot on. Now

your speedometer is closer to accurate, so your odometer will be off. But what the heck.

I use a bicycle computer on mine for a speedometer/odometer/trip meter and it is exact.

But my speedometer reads about 15 mph fast at around 70 mph.

Joel are you serious, low and mid grunt you were missing returned after you re-fitted the flapper, sounds more like a placebo effect! Can't believe that's possible!

Glad everything else is working well for you.

Well all I know is that when the flapper is disconnected, the bike is noticeably tamer at low end. I have hooked it up and then disconnected it several times. I did not read about it having that affect with other people until I had come to the conclusion myself. I actually liked the riding better with it unhooked as I was able to ride in parking lots without looking like I was on a bucking horse.  Its not that I couldn't ride slow and  cautions, it just took much more throttle concentration. Call it what you want, but I call it tamer with it disconnected. Now that I went up a tooth, I figured I could hook it back up again and it would not be as severe, and it wasn't. I still have a surplus of power but can ride in a lower gear than I was more often....less shifting up and down between lights is a more comfortable ride to me. I am not trying to sell anyone this. I am just reporting my findings in case someone else is bothered by a few of the things I am claiming that it fixed.  To me this is a touring bike that looks sporty. If I wanted a bike that stretched my arms when I jumped on it, I would have bought a cbr1000rr. 

It was only a $20 dollar risk for the sprocket, and you know it doesn't take more than 20 minutes to change. 

I like it and it is staying this way.

Surely you have heard time and time again that others claim exactly what I am claiming the flapper does. I have read several posts just in the last month alone. 

Like this one - 

"My opinion on the flapper mod has always been that it only achieves loses and no positives".
