Sprocket

[opds9091]

back in December b4 i got hurt i changed the rear sprocket +2 to a 48. I took the bike out for the first time ttoday for about 15 minuts. Well im not sure if it was not rideing for allmost 6 mmonths or "HOLY CRAP", THE FRONT CAME UP SO SOON". I will take my time, but going +2 in the rear (and thats the bike rear) gives it so much more BITE. This should be one of the mods done ASAP.

Well, glad to hear it really improves the zip. But, n-no-way am I going to do this mod. I want good mileage, lower RPM's for cruising. Curious how much your mileage and RPM's change. How many RPM's at 65 MPH? It's around 5300 RPM's for stock sprockets.

I am very glad you are on the mend mate,
Spare those horses a little, you got a nice long riding season ahead. Did you upgrade the chain as well? Also out of interest why did you do the rear when the front is the cheaper option?

I don't think that the speedo and RPM will corallate against stock gearing. I know it will be out but how out I am not sure. I think a speedo healer would be of great use.

Doesn't running a smaller front sproket wear the chain out faster?

I have no idea mate,
I guess it may be working harder, but the wear would also be along the drive shaft to as that has to turn faster. I am people mechanic and am more than happy to listen to those who are more mechanised than me.
I was thinking that two extra teeth at the back would be much larger and probably take up all of the stock chain free play.

If it does the difference is not noticable by much. If a stock chain goes 20,000 miles before you need to change it, the smaller sprocket might take 1000 miles off of that.

I know plenty of people that have 18 and 19 thousand miles on chains with a smaller front sprocket.

My sprockets right now are one down in the front and 2 up in the back. I just got back from lunch and my RPMs were at 5500 at 65. NOt much different than stock. My last tank of gas carried me 198 miles before i filled up so i think my gas milage is pretty good since i only put in 4.35 gallons in. That is 45.5 MPG, not bad compared to my truck.



I hope this helps and by the way, the sprocket setup i have makes the bike 10 times better on acceleration.

-1 in the front or +2 in the rear = best mod eva!!!

i bought the 520 conversion kit, Red chain, Black rear sprocket +2, and i still have the front sprocket -1 which i didnt get around to.
