    compression mystery?

    Yep. All sorted. On proper inspection, it was a damaged gasket. Now I have to sort out the muffler. I wasn't able to screw one of the studs in far enough and now it sounds like crap. Any body have any suggestions on how to solve this. I was thinking of chocking the bolt with some washers? Is...

    compression mystery?

    You were right on the money, Motodevo. I backed the clutch adjuster off inside the cover and then tightened up the bolts and had compression again. Win for me. Refilled the oil then kicked it in the guts and she fired straight up. Another win for me. Gave it a few decent revs and then...

    compression mystery?

    The motor actually kicked over when I had the crankcase off. When I put it back on, I slowly tighten up the bolts and it still has compression, then as they get tighter, it looses compression. Is it possible that the crankcase is squashing the clutch, causing it to engage? My old motor...

    compression mystery?

    Hi guys. I'm in the process of putting a second hand 125cc lifan into one of my pitty's. The right side crankcase had a crack in it so I took one off one of my old engines (exactly the same motor ) and put it on. Only problem was that once it was on, the motor had no compression. I took it...

    140cc wiring help needed

    I ended up wiring the unknown red/white wire into the blue and white wire and was able to get a weak spark. The motor sounds like it might kick over but I can't get it to. Out of curiosity, where could I pour some fuel into the carby to hopefully get her to fire up? I've tried a little into the...

    140cc wiring help needed

    Wow! 75 veiws and no replies. I must of gotten the only one of these engines ever made. Haha. I googled gongyu as written on the side of the motor and came to the conclusion that they are an XY motor but I still haven't seen the same wiring set up. I read somewhere that a guy wired the red and...

    140cc wiring help needed

    Hi guys. I know that there is plenty of threads and YouTube videos about this topic but I still can't seem to get it right. It doesn't help that I am not sure what brand motor I have either. There are no markings on it other than 140cc. I'm sure that thumpstar motors would have it stamped on...

    2nd hand motor help

    Haha. Thanks for the encouraging words motorman. One of the donks is a 140cc which he said,and looks, was less than an hour old. But for some reason, both sides of the motor are off. It looks clean as, and I can't see anything wrong or loose within the motor. Can anyone post up some links as...

    Some of them don't want to turn over, is that normal for a motor that isn't in a bike?

    2nd hand motor help

    Hi guys. I just brought 5 lifan motors second hand and was wondering if you guys can give me some pointers on what to look for in regards to what might work straight away and what ones might require some love. Old mate said that they all run and I'm sure that no one has ever lied on Gumtree...

    Lifan 125cc vs ducar 125cc????

    I wish I could join the debate. I have a lifan 125 that went hard for a couple of rides then started slipping in second and third gear. I was riding it around the yard last weekend and for some reason, the compression just disappeared. I tried adjusting the valve clearances following some...

    To strap or not to strap

    What kind of straps does everyone use? I have seen people use straps with a carabiner attached to the end so that the hook doesn't fall off while towing, which makes perfect sense but I was wondering what people think of the cam buckle style over the ratchet style. I'm sure that the cam buckle...

    My first video.

    Hope you all enjoyed the video even though it isn't anything too exciting. Just out of curiosity, what video editor do some of you guys use. I have been playing around with the free kinemaster app from the Google play store (hence the YouTube name Captain Kinemaster ). I don't have a computer...

    Revolution Mx info

    Hi guys. I am only very new to pit bike riding (any riding really ) and went to Marshall Motor sports the other day for a look and to hopefully get some info about anything pitty related. A fella came over asking if I needed a hand. He was pretty good, explaining a few things and answered all...

    Man's best friend "and other pets"

    Bugger about the goat,mate. There is a fella with one near here and he has an old Land Rover in the paddock with it. It's nothing to drive past and see the goat just chillin' on the roof.
