Good video but could of told us the front sprocket nut size lol 🤙
*For anyone else it's a 36mm socket.
Good video, informative. Thank you.
There is an opinion that if you periodically flip the sprocket, the chain lasts for longer use. Have you heard of that?
Never heard of that... The front sprocket usually has a boss on it that is for spacing the sprocket from the transmission so I would not recommend doing that, I am not sure why flipping the rear sprocket along the X axis would help that much other than the leading edge of the teeth but with the teeth already worn on the opposite edge I don't expect this hack to get you that many more miles since I believe it would also accelerated chain wear. A busted chain is no fun...
Is it correct if I use a larger sprocket in the front the low speed (10-20kmh) jerkiness & throttle snatch goes away?
Hi Jeremy, it depends on the displacement of your bike a bit. By adding a tooth to the front your bike's engine will need to generate more torque to perform the same movement. It will be slightly harder to pull away from a stop and you may need to feather the clutch or use more RPM than before. In a low displacement, under 600cc this can make the bike bog and want to stall at very low speeds. A large displacement bike with loads of torque can feel a bit smoother with a front tooth added and may smooth throttle response, especially if you feel your bike likes to wheelie and you don't. Adding a tooth in the front is like taking away two or three teeth in the rear sprocket. Your bike will run at a lower RPM at any relative speed than previously so throttle response and torque is diminished on lower RPM and you will see a higher top speed at full RPM. I hope this points you in the right direction and good luck!
@@RodRidesWrenches thats some detailed information. Thanks for taking the time. I own a Speed Triple 2010. A dyno tuner told me if I use another sprocket without tuning the Ecu I will just replace the jerkiness to another rpm!
A sprocket is cheap to try, worst case you've spent $20 and a hour of your time. It will make the throttle a bit lazier from your perspective so it may help. You have all the torque you need in a speed3 so I would give it a try. You can also go down a front tooth and rev a bit higher to get through a rough spot in the fuel/ignition map faster. Just know that your going to have more torque at your disposal then.
If I change sprockets on my 09' Speed Triple 1050 will I have to correct the speedometer as well or will the motorcycle auto correct for that? Please reach back!
Hi Josh! If you change more than a two teeth on the rear OR one tooth on the front, the speedometer will be out by about 5% the more teeth you change the more it will be out. Adding teeth on the front will make the bike speedo read slower than actual while dropping front teeth will make the speedo read faster. The opposite for the rear wheel; adding teeth on the rear will make your speedo read faster than you are actually going. This is not a big deal IMO unless you are concerned about the odometer since most riders are looking for more torque they drop teeth on the front and add to the rear, getting more RPM at any average speed and making it easier to wheelie. This will add more miles to your odometer than you actually went. The speedo sensor on your bike is by the front sprocket and reads from the transmission. There are companies like healtech than make adjustable sensor manipulation tools that just plug into your harness between he sensor and the main harness. The Sprint ST 1050 I had used one and it was a piece of garbage IMO. That bike initially had very low gearing (more torque) and it was not great at high speeds. Even at factory gearing that bike could power wheelie so that is what I used for sprockets, factory settings. I have dropped one front tooth on one of my VFR800's and much prefer this to stock so should expect to experiment a little. Good Luck!
Chain adjustment has to be done with motorcycle on sidestand and rear wheel on the ground.
Good video anyway. 🇧🇷
You can add 5 mm more of chain slack if the bike is not on the side stand to compensate that.
I have measured that on my Triumph Tiger, and it works pretty well. My bike does not have a center stand and it's not easy to move the chain adjuster.
