rear sprocket,supermoto re build

[scarykxer]

 :?hey all you fellow kx riders,can anyone help me with a problem,i have re built my1995 kx500/580 and converted to supermoto,problem is rear wheel is the usual exel/talon  4.25in with a Maxxi goldspeed 150-60-17,i bought a gold 40 tooth solid talon sprocket,with a standard h/d chain,but the chain is ripping the tyre worse than usual....has anybody else encountered this problem ??        also i wanted to post some pics in the gallery now the beast is 99%finished,i guess being a newbie i cant get access,any help on both problems would be great...thanks guys

I think you have to have more than 30 post to use the gallery.

have you tried maybe a 15 tooth sprocket on the front?

thanks for the gallery info,as for the front sprocket i will try a 15 tomorrow,seeing its dark in england,im looking forward to finding the right sprocket mix for some serious fast road action that will induce nervous laughter as the bfront wheel points to the sky with every gearchange

I run 4,25 and 160-60-17 and shave off little at chainside.You can also loose spokes at left side and thighten them opposite,you earn space at chaindrive and it does`nt mess up so much alignment at it bother anyway.

thanks doordie,the wheel is off for about the 50th time,so i will try what you said,dont get me wrong,i know the chain always seems to catch ,thats why i went for maxxis cos they dont seem to be to wide,just sold my husky sm570r which i fitted avon azzaro,s,the rear being a 150 and once fitted it looked more like a180  i had to dump my o ring chain and go back to standard ,now i have bought a ktm525exc with a 160 continental and o ring chain,misses the chain completely.....

When the bikes stationary I have about 3-5mm clearance between the chain and the tyre side, as the bike runs it must slap about a bit cos it still catches on the tyre slightly and makes a spirograph style patern on the tyre.

Of course nobody I know would ever consider taking the very edge of the tyre off with a very sharp knife or even a power planer set to about 1mm...

Losening the spokes on one side and tightening the spokes on the other should also help a lot. Just make sure it's done evenly, if you don't feel upto it send a PM to Brokenlegs who uses the visordown Supermoto section as he has rebuilt the wheels of loads of lads on there..

One of these days I will just bung a chain guard on there so the chain doesn't slap about quite as much and even though I don't legally need one it does look better when I get pulled but I have not yet got round to it.

 :lol:getting pulled  on supermoto,s,sounds like something that happens to those hooligans who cant leave a set of traffic lights without aiming the front wheel at the sky,my local plod seem to have a problem with the glorious sound of a titanium pipe on full tilt in a built up area,whereas i think its one of the best sounds ever,gotta say its 3 years since ive had a kx500 on the road,and the neighbours are dreading the sound of an angry wasp buzzing the area early on sunday mornings but i dont care,cheers for spoke advice,i will tell you how i get on
