  • What happens when you change sprocket sizes on your motorcycle? How does a bigger sprocket or smaller sprocket affect performance? More teeth? Less teeth? Which is right for you?

    Stock gearing on my 650 is 15-47, I'm going to go up one on the front to 16-17.
    Great videos.

      I think that is aa good move, especially if you ride on the highway often. Probably a little less punchy off the line though.

    Hi Urban Monk, I'm going up 2 teeth on the rear. Can I get away using the stock chain lenght?

      Thanks for watching. That depends on the bike. I did with my DL1000 and got away with it but I would take that on a case by case basis. I couldn't speak for other makes/models.

    Hey mate, love your DL videos, I just bought a 07 DL1000. I need a new chain, so ive been following your amazing videos.
    My question is. Where is the best place to download a service manual for my bike. Cheers

    Good explanation of the leverage aspect part of this. You might expand a bit on the ratios considered as the ratio from front to back obviously is the most important consideration of choosing sprocket changes for low end torque or high end speed and efficiency. Cheers to the Urban Monk. Your video on water pump rebuild recently came in very handy and I’m working through the ride series a little at a time too! Be well and ride safe Monk!

    Hi urban. Have you ever had any problems with your own bike regarding exhaust backfire ? Mine has started doing it when you are slowing down or when just cruising along at a gentle speed and the throttle relaxes on a slight down hill gradient . Really embarrassing when riding through quiet little village or busy towns and the bike decides to let go! Thanks Rob.

      I assume you're referring to my V-Strom. Yes, before I installed the Power Commander it would do that under certification conditions. Usually 2nd gear with rpms between 2500 and 3200. PC fixed that. Hasn't happened since.

      @@UrbanMonkTV sorry, yes, the v-strom. Iv done the obvious as in spark plugs and putting injections cleaner in the tank. That one might take a week or two to kick in. The PC might be an option later on . Will check air filter today but got feeling tells me no as not long change it. Anyway, thanks on the advice. Will let you know how I get on,, cheers Rob.

      @@bobbyedal2737 While you are under the gas tank, check that the MAP sensor hose hasn't become disconnected for some reason, that could also do it, but it is less likely. These 1st Gen V-Stroms are known to run too lean with the factory fuel mapping. You may also check to see if there is a recall for your ECU. That may fix your problem but the concern would be that the mapping is same in a new OEM ECU as in the original. Perhaps they've updated the settings in replacement ECUs though. That's a guess on my part. Again, Power Commander allowed me to change my own mapping to eliminate the problem.

    Interesting content. I hardly use 6th gear because I don’t usually drive on highways with the speed limit that high. Maybe I could have or should a more efficient sprocket pair ? Then I can use that 6th gear. Thoughts ?

    • @UrbanMonkTV
      @UrbanMonkTV  Před 2 lety

      Thanks for sharing your comment Craig. An engineer would look at the use cases for your machine (as you are) and strike some kind of balance between the user experience (including your experience at the gas pump as well as performance), wear on engine components, and stresses on materials. You may find you like the "feel" of a "better leveraged" sprocket paring, and in theory this would put less stress on some engine and transmission components (clutch included). But conversely, the resulting higher engine rpms would mean piston rings making more trips up and down the cylinder walls, more revolutions within bearings a seals, and more air volume moved through the engine. You may not be pleased with the resulting fuel economy, and engine/transmission component properties are already considered by engineers. I'd say it mostly comes down to whether your use case differs greatly from the use case scenarios that were given more weight in those engineering decisions. Try it out and see. You can always go back to original OEM specs.
