Has anyone had trouble placing a 120/90/10 on the rear of an ET4 year 2001???...

yes - only recently - exactly the same bike - exactly the same year - i cannot even get the back wheel off!!! i need help!

you have to take the exhaust off (or maybe just the silencer) to get at the rear wheel.

I managed to do mine using a basic tool kit from halfords and the haynes manual. if you take the rim to a bike shop they'll put a new tyre on the rim for you.

thanks for the post damodamo - i have already taken the exhaust off - it is on my kitchen floor at this moment - it is the nut holding on the tyre i cannot undo - three of us tried but with no success! a whole can of wd40 was applied to!!

sorry i meant wheel not tyre! i am mechanically illiterate! even lego technics fazes me!!

did you lock the wheel (cable tie/bit of string holding the brake lever down)?

may just need more leverage on the socket wrench, try using a longer wrench or a breaker bar. It will come off eventually.

The hardest part is getting the exhaust off and on...

+1

Get a breaker bar...they are not expensive and you'll need it again eventually. Don't oil it! You'll want to put that nut back on again, and have it stay on.

Holding the brake may not be enough to lock the rear wheel...see if you can borrow or make a clutch holding tool. Check the Wiki.

Yes, they are on tight.

The recommended torque is 100 ft lbs to tighten btw.

That's akin to putting a 1 lb weight on the end of a 100 ft socket handle (if there was such a thing ), to give an idea of the leverage involved.

You are turning the spanner the right way, that would be down at the back?

100 lb/ft is a bit high. 70 is good.

Hah! Found it...

Usually, I'll post a link instead of saying "search" but I had to run out.
Back home now.

Scroll on down until you find how to make a DIY clutch tool.

That and the breaker bar will make the job a breeze.

When you get that wheel nut off, watch for the washers, there will be a couple, and make sure they go back on exactly where they were originally located.

deffo, make sure its not oiled when you put it back on!!

Where abouts in Uk are you? if its anywhere near to leeds i wouldnt mind driving over and having go for you.
