Sprockets

[mylovelyhorse]

Evening all,

I have to replace my chain & sprockets soon. I have acquired the chain (116 links of DID X-ring 525) but I have not got my sprockets yet.

Anyone care to recommend a supplier? Any point in looking for a specific brand or is a sprocket a sprocket?


Actually, while I'm here, any particular gotchas or things really worth knowing when changing chain & sprockets?

Cheers

M

Are the sprockets worn? Are you just changing them because because? I wouldn't bother. I didn't on mine. Third chain 20,000 miles. Don't ask. Now have a DID chain. JJH

Hmm interesting. I thought that it was always best to change sprockets at the same time as the chain to avoid excessive wear on the new chain.

Stick a one tooth bigger sprocket on the gearbox, It makes for a more relaxed ride on the boring roads and helps a little with the economy, if my memory serves me right the 650 twin has the bigger sprocket, Motoworks is a good supplier of all things BMW

+1 for bigger sprocket, I've got the 17 tooth of the 650 twin, drops rpm by 500.

Done the same as well makes cruising at 75 more relaxing

The advice on the front sprocket is taken - thank you everyone that gave it. I shall get onto Motorworks this morning.

My 116 link DID X-ring chain turned up this morning, now all I need is a reasonably good chain tool

Does it affect speedo accuracy at all?

Doesn't affect speedo as its taken from the abs sensor. Best to change sprockets and chain together. Wemot are someone I've used for chains and sprockets.
Remember to adjust the chain at the tightest point.

I have changed a fair few chains in my time and never used a special tool. Two hammers. One lump hammer on one side of the chain the other a ball pein to hit the rivet. Never had a problem. How to split? Use a angle grinder on the rivet. Jjh

I'd agree with that. Worked for me.

Does that work on o ring chains when I have done them with the tool you need to compress the plate the correct amount so you don't squash the o rings and end up with a tight spot or not enough and end up with a broken chain eating the engine casings at 80 mph ?

I've never had a problem I ring x ring or whatever. I haven't used one of these tools but what's to stop you over tightening with one? I'm asking because I did not think that they were that exact. Are they? I've never thought about it that way. I'm worried now. ...... Not. JJH

Replace the Chain & Sprockets While Drinking Coffee...

...and reading a magazine.
It's called 'phoning Jap&German and saying "I need a new chain and sprockets fitted on my bike"'. Two days later you leave the bike there, walk round the corner to the really good coffee shop with a copy of your preferred bike magazine (Bike, Adventure Bike Rider, or Overland in my case). Spend 45 minutes or so having a coffee and a read. Go back to Jap&German, give them some money, ride away all sorted.
You don't need a chain breaker, angle grinder or, indeed, any tools what so ever.
I've done the oily hands & skinned knuckles thanks, I can now afford to keep a mechanic in business plus I don't need to find somewhere to keep a lot of things I will only use once in two years.
If you prefer to do these things yourself, good for you. But there are a lot of us out there that don't.
That's what keeps people in business.

Control over the amount you squash the rivet so when its all done its within the chain manufacturers specs and evenly spread out without been cracked or not flared off centre I have never tried using hammers but the correct tool makes it dead easy to do and the tool is not expensive.

There are people in this world who get a lot of satisfaction from working on their bikes, while others prefere to drink coffee. For me, working on my bike is very much part of the pleasure.

Me, I like a bit of both. When I think I'm out of my depth (e.g. valves) then I hand over the plastic to BMW & they do the stuff. For this, I will enjoy sitting with my bike and doing it - including acquiring skinned knuckles if I get them. It makes me feel closer to my bike and also avoids my bank balance shrinking even further.

I have acquired a tool, Motorworks have supplied sprockets (including a 17 tooth front as advised) and I will be doing the work in a month or so, once the crud is easing on the roads. No point chewing up a new chain with Winter
