Yep, sell it and buy a cr125 Seriously mate not worth the trouble. Could be dangerous too.

Maybe illegal at proper race tracks, but they arent the only tracks on the planet mate. In Vic we have a thing called rec reg so you can ride in the bush. If your talkin bout this, no you havent seen them on ebay, those are overgrown pit bike heaps of shit. :::::  S I K K   T O Y S   M X  :::::

Yep. Your looking at a 50kg dirtbike / or a powered down hill bike. Depends how you look at it. Its powered by a 140cc lifan start any gear etc. Front end components are of a downhill bike, 200mm travel forks with a 200mm rotor. Rear is a 19" wheel, which is the front wheel of an...

If its got fark all top end the screw wont make any diff. Fuel screw affects the bottom end only. If your plug is sooty try a smaller main jet, or drop your needle.

Down hill bike - come pit bike. Uni engineering project.

Ok thanks for the input. Sounds like il have to strip it for a squiz anyway. 2 stroke engine would be good for this project, maybe phase 2 :D

cam chain adjuster. pushes on a rocker which pushes down on the chain.

bumpy bump, cmon guys

I dunno what you are on about, but sounds like you know fark all about it mate

New tyres first up bloke, those are shite! Save the rest of the do for shit that breaks.

Ok heres one for the Pit Bike gurus. Id like to know how these Lifan engines lube the cylinder and top end. The engine I have is a 140cc 1P55FMJ Lifan, which has the two outlets for an oil cooler underneath on the right hand side of the casing. I want to (need to) tilt the engine upward...

They are KLX110 rad shrouds, rear fender, front fender and front num plate but not side plates. CRF stickers wont fit.

Yeh mate good one seen u do DHZ and monsoon bikes as well.

Dude ur 25mm mikuni is just right for the 125 Put in a 105 mainjet with the needle in the middle position, and tune the air mix screw. Best you will do. Remember its just a pit bike.

Think about a standard engine. You have a flywheel on one side of the crank. On the other side you have the entire drive to the back wheels. It is already unbalanced. I cant see how you can snap a crank simply due to an IRK.

Where did you get it from? Did you get a CDI with it? Those two wires go into the cdi.

Ridin, i have the same bike. It will prob be the exhaust. Its a 3 pice exhaust, and the middle piece just sits there, and rattles. Get some small exhaust clamps, and tighten her up!

OK. so im sick of hearing about 'you cant put an irk on a non start in gear bike cos ul snap the crank' Has anyone actually ever seen one? Simply due to the lightened fly wheel? Ive had one on my Lifan 120 for ages. Its a non start in gear, has a hot cam too. Revs like all buggery. No...

My Lifan is a 120 with 52.4mm bore. Its in a PitPro outlaw. Its a 1P54FMI It has 124cc stamped on the bore, and i measured it to be a 120cc, so dont believe anything with these dodgy chinese. According to the guru's at Akunar.com, my lifan engine has a Jialing cylinder (hence the 124cc)...

Yeh cool , no oil cooler on her. Just bought one so will throw her on and see what happens. Dont think running lean will make it get hot. Thats more a 2 stroke thing where the fuel is also the lubricant. Less fuel less lube more heat. I think because the Cam is now letting more fuel in...
