    1982 Yamaha GT80?

    I have an 83 MX100 and can confirm that yes you can get parts for the engine but they aren't cheap and if you're on a budget you will need to keep a lookout for them. On the front of the colour scheme, I'm unsure, could have parts off an 80 because that's what he could find that would fit in the...

    Are There any good places to ride a pit bike in Perth?

    just really comes down to whether you are south of the river or not, because living south is like the region I know so you are really better off trying the dirt bike groups for perth on facebook as there are riders from all over the state on there

    Are There any good places to ride a pit bike in Perth?

    Kwinana offroad, next to the motorplex is really good, stakehill is fairly popular too, ther are obviously the mx tracks such as costals, ducks nuts and dirt riders heaven but the last two are fairly far north and all the tracks are obviously pay to ride

    upgraded cases.

    I was unaware that they had that issue although I do recall reading about several people who have had issues and it makes sense now. Should be okay as long as you use proper kicking teqnique

    XTM 200 studder at full throttle

    I have been given an XTM 200 with a ZongShen 200 engine, I have ridden it a few times when my mate owned it and have noticed that when held on limit in fifth gear for any more then a couple seconds it seems to die out and splutter but then you release the trottle and blip it a couple times and...

    Pitbike newbie help

    sounds to me like either the shift drum is in the wrong position or one of the shift forks has snapped, maybe other things but that seems most likely to me

    Hummer Make/Model identification HELP PLEASE

    they are all fairly similar but the horizontal engine pit bike parts will not be interchangeable. eBay will be really good for parts but most of the parts should be interchangeable between the two. Crf 250 plastics should suit the bike.

    Hummer Make/Model identification HELP PLEASE

    on the cylinder somewhere there will be a number, I'm going to say its either a 200 or 250. Crf 250 plastics will suit it and they run 14/17 wheels, a bit smaller then jap and European bikes

    Hummer Make/Model identification HELP PLEASE

    I have just searched up pictures of the hummer bikes and it seems they have vertical engines, not horizontal. This means that its either a 125, 150, 200 or 250

    Hummer Make/Model identification HELP PLEASE

    post some pictures and there will be a lot more help under the sprocket there should be an engine id code, on the cylinder, it will say what cc all good pit bikes are four strokes. There are also a lot of possible cc's, 50,70,88,90,110,125,140,150 and 160 are what i would consider the possible...

    dual perimeter frame mini builds

    does anyone know what head bearing they would run, one frame has the really steep angled bearing that are probably 10 mm deep into the head stem and the other has the usual very shallow curved bearing that sit probably 5 mm into the head and wrap around the bottom of the bearing

    dual perimeter frame mini builds

    So I've been lurking on the forums for over a year now and finally managed to get my hands on something to build. I picked up two perimeter frames for 50 dollars, they were a bit dirty but were complete (frame, swinger and subframe) They came with three swingers, two seem to be the stock...

    New thumpstar bikes 2018

    the frames look like they have dodgy casting or machining because when you see up close photos they just look messy

    Lifan 125 build

    I was more thinking of boring it to 56mm and then getting a shorter rod to get come more rpm out of the engine

    Loco's Ciniworx cxf build....

    what came of this bike, it's probably my favourite bike ever built. As in yours specifically and after all the troubles it leaves me thinking if shes still going

    New thumpstar bikes 2018

    they seem very restricted in the exhaust, my mate has that pipe on a z110 so if you were to get one I would buy a new pipe. There are other little things that would pay to change. Levers would probably snap easy, swingarm would be questionable, rims as well and the bearings would be something to...
