Love the way u guys have got these poles lying around to extend leverage on your socket bar. I'm in the UK running out of ideas of where to get hold of one of these. I understand removing the sprocket nut can be a nightmare. If anyone can make a sensible suggestion I'd like to hear it.

[daveflr]

@Knightlore10 To Get the Poles , I just went to a local Hardware store like Home Depot. Take the half inch socket wrench with you so you can get the right pole and it has to slide on the handle of the wrench but make sure the pole hole isnt tooo big or small to fit.

What about the part were you actually take off the chain,and sprocket...LOL.Need more detail

[daveflr]

@joshmaster618 Well if you can't figure out how to get the chain off then it would be better to take it to the bike shop. I will tell you anyway. First you take the cotter pin out that keeps the nut from falling off. Next loosen the nut just enough to move the rear wheel then Loosen the chain adjuster located on the swingarm ends. When changing the front or rear sprocket you do not need to take the chain apart. Now the chain should be loose enough to take off the sprockets.

how did youn know it wa time to replace it because im starting to hear some noise coming from that area

[daveflr]

@busaboyrule1 When it is time to replace the sprocket, Look at it and see if the teeth are looking pointed and look thinner. Always change both spockets and chain when replacing any of these parts. If you don't the life of the part you change will not last long and will need replaced again.

Hello Dave, very helpful info here! I would like to get more "get-up-and-go" acceleration, such as immediate quicker "out of the hole" type speed. I have heard other people talk about changing the front to down 1 tooth, and rear sprocket increase 2-4 teeth. Is that true? And if true, then why don't I just leave the front sprocket alone, and just change the rear sprocket to even more teeth increase, wouldn't that be less work, than having to change out 2 sprockets? thank you

@hayabusarider168 Changing the front and rear sprocket has opposite affects on the bike. If you go:

Smaller in the front: gives you more power, less top speed

Bigger in the front: giver you less power, More top speed

Smaller in the rear: gives you less power, more top speed

Bigger in the rear: giver you more power, less top speed

One tooth less in the front = 3 teeth more in rear.

Start with -1 front because if you go up in rear you will need a new longer chain.

Hope that helps =D

[daveflr]

@VRCommy I have found that replacing the front sprocket isnt a good idea. I changed the front spocket and the rear on my busa, (16 Front and 44 Rear ) The problem I got from changing the front spocket one tooth less is that it gave way too much stress on the front counter shaft and ruined my countershaft oil seal and also was very hard on the transmission when I opened up that throttle , and now I had to replace a few gears. So keep the front stock and change the rear teeth if you like.

[VRCommy]

@daveflr Oh ok, you make a good point. I just went with -2 in front because then I can use the same chain, instead of needing a new one if I went +6 in the rear. But I didn't think about the other issues. Thanks!

YW, and if you have any future problems with your bike feel free to ask and if I can help I will do my best to help you.

[glurknobia]

Dave, that was VERY helpful - I need to do a front sprocket on a '97 RF900 and found the same thing - no tutorials, no where - so thanks again, your video was a big help.

[Daveflr035]

One other thing. If the sprocket still has trouble comming off you can use alittle heat (BUT NOT TOO MUCH OR YOU WILL DAMAGE THE SEAL) and then tap it with a rubber mallet or use a hammer but cover the hammer with a towel (2 FOLDS) and then tap it loose. If all fails then get a gear puller.

[Daveflr035]

The spocket came off but it was realy snug on there but I did use a rubber mallet and taped it a few times till it worked loose and it came off.The spocket that I took off on this video was still the original sprocket.This was my first video ever on youtube and I just hope it was useful for you people out there that need help.Just a reminder the big nut and the hex bolt in the center of the nut that is on the shaft is the only thing keeping the spocket on once removed it should come off.

[cjp091068]

did the sprocket itself come of relatively easy or did you need a gear puller or something?

[daveflr]

@cjp091068 Just tap it with a mallet and it should come off relatively easy, if not then spray it with WD-40 and try again.
