Puncture Repair

[woll]

I got a puncture in my rear wheel on my dt a few weeks ago (its an mt21 tyre) im not sure if it's tubed but i went on wemotos website and ordered a tube off them but its not the same size as the tire, the tube is a 3.50/4.00-18 and the tyre is a 120/90-18 will it fit? If not then is there a cheap but reliable way to repair it myself? i was thinking of the green slimey stuff that you put in mower tyres etc.

I think Wemoto sell the motorbike tube repair kits.

Are you putting on the tyre yourself? If not just take the loose wheel down to a bike tyre place and ask them to whack in a tube that fits.

4.00 converts to 100, so the tube is a little on the skinny side, yes!


You really need a 5.00 for a 120

Staniforths list the tube size for that tyre (120/90-18)
as 110/100 x 18 (mx tyres)

so im going to have to spend more money on it then, not ideal was hoping i might of got away with the thinner tube, i've got the wheel off not attempted to take the tyre off. I cant see anything in the tyre and it is quite a low tyre which is why i was hoping to use some slime or similar
