Changing a front sprocket for dummies

[sc0tt]

Dern has very kindly sent me a -1 tooth front sprocket for my r1 because obviously it is lacking in the acceleration department.

How does one go about changing it?

Will it fit my Standard chain?

meaning a shorter wheelbase.

And what does that bit mean?

Don't forget to get the right torque settings for the sprocket.

So I take it you'll hoisting the front on rides out now?

Sounds simple.

I'll ask my mechanic I think. Peeeeeete

I jest.

I'd like to, we will see.

Good lord. This sounds complicated.

I'm assuming it's worth it. Or is it likely to make the bike just try to rear its head everywhere?

You want 15-49 sprockets on for wheelies

I can't do wheelies.

Evening classes motor mechanics or DIY based would be a good help

I have had to do many courses into time most recently it has been it based stuff

Everyone has to learn so get off your arse and gain another skill set

Xxxxxxx

No issues with mechanics believe it or not ...





Just a total lack of tools at the minute.

I own an allen key and a screw driver.

I don't think showing him you can take your airbox and subframe off is going to impress him.

Possibly not. Just demonstrating I am not inept.

Have you bought an MV?

Sc0tt - bring your sprocket and muscles tonight and I'll change it with you.

Does your swingarm have crash bungs/cotton reals fitted so I can get it onto one of my paddock stands? It'll be a bh of a job otherwise and I'm not sure I have any spare M8/10/12 bolts or whatever the Yamaha thread is, to screw in temporarily.

I'll IM you.

Tonight isn't going to be good for me. I was out on the town last night and I erm haven't been to bed yet.

Sorry buddy.

Yes it has cotton reels.

No one has mentioned the speedo yet (except BN) where do they read from on R1s? it'll overead (even more than normal) with shorter gearing on.

By 7% I believe

No problem - next week then. We can do the R1/ZZR sag at the same time. Gives me time to oil my tools to stop any contamination from Yamaha monkey metal too.

Good stuff mate - Thanks for your help

Sorry, I should have sent instructions

The way with the least number of tools is...

Removes the sprocket cover and bend back the lock tabs a bit.
Sit on the bike and apply the rear brake.
Using a long breaker bar an an appropriate socket loosen the nut.
Remove the nut and the lock washer
Slide the sprocket off with the chain if there's enough room (if yo can't do this you'll have to now remove the chain from the rear sprocket somehow (removing the wheel is easy).
Slide the new sprocket on with the chain
Refit the lock washer and the nut
Tighten it up sat on the bike with rear brake on
Lock the tab washer
Refit the sprocket cover
Adjust the now slightly loose chain

Wheelie every where and condemn yourself to speed calculations until you decide whether you like it and get a speedo adjuster or you don't and put it back to standard

Cheers,

Mark

I don't actually remember opening it last night but I saw it on this side this morning and remembered what it was.

How did you find it?

Thanks again - Can't believe how quickly it came.

No worries.

I originally got it because I found that the bike was bogging down pulling away and had to use loads of revs and someone made the suggestion it might be the gearing and it was only a tenner. I found subsequently I had a problem with a coil which caused the issues pulling away. I liked the lower gearing but didn't find it significantly better to justify the cost of the speedo adjuster so I put it back to standard once I'd sorted out the coil and then it sat in my tool box for ages and then I sold the bike.

Cheers,

Mark

Cool, I'll let you know how I get on

Cheers
