Hey guys, Just installed this engine and this carburettor into my MadAss. Seems to work pretty nicely, but it's idling way too high. I've tried adjusting the idle screw, but it seems to make no difference so I'm guessing my jettings all wrong. Can anyone recommend a pilot and main jet size...

Just rang the RTA again and this time they told me to call a Blue Slip guy. Blue Slip guy said as long as the new engine is within 15% additional displacement and I have a receipt for it, then it's no problem. Sweet! If anyone wants a busted MadAss engine, they're welcome to it for $100 plus...

I've just had a lot of problems with it, clutch, tranny, stalling and after I had to rebuild it to fix 2nd gear. it ran for 5 mins and then stopped and won't run at all anymore. I can't buy a new one b/c they've stopped doing parts, so I'm kind of out of options. I'd like to find out if I...

Yeah I saw that listing. I'm thinking about it, but b/c it's a higher lift cam, I'd need to replace my valve springs and possibly do some piston mods which I'm trying to avoid. I might end up taking it though, let you know. JHZ

Hey Guys, Was in the process of rebuilding my MadAss engine (I believe it's a Lifan 120) and managed to damage the Camshaft so I'm looking for a replacement. It's a 74mm shaft with 6.7 mm displacement and has the three holes on the sprocket face. If anyone has replaced theirs and wants to...

Can anyone recommend an after-market pipe for the Sachs Madass 125 to improve performance? Would prefer to source in NSW if possible.
