When can i get spare parts and bigger jets for my 2006 mz 125 sm? thanx

try a online auction site or you could try a club that specialising in these bikes

the only place is the dealer if you want a warranty, check out bike parts yards, used bike parts similar to a car wrecking yard.

Best thing to do, would be to buy an aftermarket exhaust system, either complete, or just the muffler, a complete one would be better, as the header pipe is usally a bigger diameter. There are many brands to choose from, and varying prices. Put the exhaust on first, then worry about the jetting. Ride it first with the new exhaust, it may not need re jetting, depending on the brand of exhaust, the supplier should have the specs for any re jetting if needed. Mabey one size bigger on the main jet. Also, for extra performance, you need to alter your air box, or air filter system. A bigger exhaust will require more air flow intake to be of any use. Apart from that, it will sound great.

your clutch disc might be bad.

oil presure / level switch if you're sure and I mean realy sure that you have lots of oil and it is circulating ( you sound like you know what you're talking about)put a jumper across the oil presure swith and you will know you have the right ones because the oil light will go out and the bike will run
Good Luck Ride safe

started and then started smoking a lot please help.?are you saying it started smoking from the exhaust? or that you saw smoke coming from the electrical?? it sounds to me like you have a major short and it is burning up wiring etc. Don't run it if this is they case, get it to a bike shop for repair,,,

MZ says use: 1.2 L (just a bit over 1 quart) 15w50 15w40 10w40,,
