Hi there,

In line for a sprocket/chain change and I do like the sounds of the JMO combo...just a quick question will this:

http://www.ebay.co.uk/itm/RENTHAL-15...#ht_3731wt_907

fit on the tenere? First time I have done a change and considering the quote offered to me by the dealer, thought I'd do it myself, is the R/X front sprocket the same as the Z in other words?

Thanks,
Tom

Wemoto show a 2mm difference (spline) between the R and Z

front sprocket
 

The R front sprocket will not fit the Z , as stated above . The Z spline is larger.

The bike certainly rides more smoothly, especially rolling off to slow down and gear changes. Vibes are as bad as they've always been (in fact in the last 1000 miles they've got particularly bad hence the change of chain and sprockets � guess my problem lies elsewhere). Bike's due a service in a couple of thousand miles so if the vibes haven't reduced I'm going to get them to look at it as it's still under warranty.

Ok i bought a new front sprocket however the new one has 2 taped holes which I cant see the original has. The second problem is trying to undo the retaining nut!

Has anyone else had the same issure and how did you get around it please? Will the front sprocket fit or have they given me the wrong one?

Easiest way to undo the nut is get someone else to hold the bike upright with their foot firmly planted on the rear brake and the front brake held on (both wheels on the ground, not on a stand) then you can get a long breaker bar on the socket and it should undo fairly easily. Same process to do it up.

Some people claim you should put the bike in gear, but I'm against this as it unnecessarily transmits forces through the engine and gearbox.

The front sprocket sounds the same as mine, two threaded holes (4mm ish?) that don't seem to have a purpose. I must admit I wondered if it was the right one given it's also missing that funny rubber surround from the original, but it seems to be OK and certainly went on alright.

It is a ba5tard getting those single front sprocket nuts off (you have bent the locking tab on the washer out first, right?)... a friend of mine swears by a 18V battery impact gun - takes it off no bother, and no need for a buddy to hold the bike!

As for the two little bolt holes, perhaps that sprocket also fits another bike that uses the alternative retention system of a toothed plate and grove in the output shaft (like a number of Hondas do)?

Obviously on the XT, you fit it using the big single nut (do check if the sprocket is handed with a thicker step in, that side usually goes towards the engine) - ideally you should also replace the tab washer, but they are usually good for at least two changes...

Mine also had the two tapped holes - I assumed they were there for removal - jacking off - so to speak.

Excellent thanks for the replies, info and advice its much appreciated...Guess what Im doing this weekend :-)

It does on my bike, multiple times, no problem. They all (X, R, Z and MT-03) have the JTF308 front sprocket:
