    Problem starting Pit Pro 140cc

    It could be numerous things But the first is to make sure its at TDC when you kick. Then if its running too lean it can behave like that, I just went through it with my bike and it turned out to be sucking air through a cracked manifold seal. Clean out the carb and make sure the jets arent...

    how to tell difference between lifan 125 and 140 engines ??

    They have different engine numbers. The 125 will probably be either 1P54FM1 or 1P52FM1 depending if its the big valve model, and the 140 should be 1P55fmj, I'm pretty sure

    what to buy???

    There is a fair difference in power between the lifan 140 and 150 I dont know too much about the YX motors. I have a lifan 140, weigh 80 - 85 kg and its good for fun on tight track but certainly not a powerhouse. A mate has the 150 and it has heaps more power as it has an ORK fitted, bigger...

    abit of help anyone?

    When you say the "type R" I imagine you are talking about the pitpro model. If so I think its a start in neutral motor, if so stay away from IRK's. Ask Rotn50 how many clutch baskets he destroyed after fitting one. They didnt last at all and he ended up just buying a 140. Heres a link for some...

    new pit bike

    I just got a 140s from Brissy and the bike is great quality. I honestly dont think you would get a better bike for the price. The frame design is nice and strong and the suspension is pretty good, its way stiffer for jumps than the Pitpro I had before it. I did have a few teething issues at the...

    What Bike Should I Get?

    For your lil bro, maybe look at a pitpro 110. They are 110cc, semi auto with 10inch wheels or I no that one bloke on here bought a 12/14 combo one. The 10's would probably give the seat height you want

    lei moto xk 90cc crf50

    Are you sure that there isnt something holding the swingarm in place from the packaging? My bikes have always come with a metal bar between the swing arm and frame in place of the shock. If there is absolutely nothing to restrict it than I would guess the swingarm bearings may be seized but you...

    lei moto xk 90cc crf50

    Yes put it in neutral. Dont touch the rear brakes, if the chain is that ight it stops the wheel from spinning. Just jack it up so both wheels are off the ground, dont have anything touching the wheels that can interfere. Loosen the rear axle nut(the bigish nut on the right hand side on the big...

    That hose is your crank case breather hose. It doesnt lead to anywher it just sits down the back of your engine out of the way. If the pedal is only steel not alloy which I imagine it is, you can straighten it using a couple of vice grips or multy grips to twist and maneuver it, they straighten...

    DMX Pro 140 cc

    When you say DMX/Atomic Nitrous, are you saying that they are the same bike like Orion/Atimok? I'm not arguing just curious as in the mag both the DMX and the Nitrous are reviewed seperately and look totally different. Is the DMX basically a Nitrous with a few parts changed? If so Coolie would...

    DMX Pro 140 cc

    Its really hard to say if 1799 is good value as I havent read any feedback from people who have owned one. If the forks are genuine Marzochi's I'd probably say that its worth that much but I dont know if its a real bargain. In the 50 brotherhood they reviewed one and really the only bad thing...

    DMX Pro 140 cc

    You'll only get an MSO if there's one floating around at a dealer somewhere. MSO the company doesnt have any more bikes. I dont know if they are still operating but you could try to contact them from their website and ask for your nearest dealer. Thats probably your best bet as far as finding an...

    how do you clean your bike??

    Why the hell would you want to spend heaps of time cleaning it? My bike is for riding not puting in a "cleanest bike with the most shiny bits competition". I just cover the filter , plug the exhaust, hit it with the gerny, wash it with a bannister brush, and dont spray too much directly onto the...

    PP140 forks...

    Why would you want it to be at full compression? That would mean that your bottoming out all the time. Sounds like their working fine to me unless your jumping big and their locking up suddenly near the bottom of the stroke.

    Review; 2009 Pit Pro 125cc RR

    yeah better bars like Pro tapers or Tag metals + some better grips are a must. The only reason I didnt say them before is that bars are a mod that pretty much every china bike needs and I just took it for granted that someone would have already told you. Just consider that all the money that you...
