    Going to try the new Hummer G4

    Hi Eban, It's not unusual to get a few chips in the oil whilst you are running these bike in. The trick is to change the oil fairly often (say every 3 or 4 rides) and not thrash the crap out of your motor for the first 500K You have to remember that the engine finishing technology on these...

    Going to try the new Hummer G4

    The original Hummer rear shock had both rebound and dampening adjustment screws and was a good quality component to work on. It sounds as though this has been replaced in later models with a cheaper component. I'd advise you to try and get hold of an original replacement unit on e-bay, which...

    foot pegs Has anybody busted a footpeg on their Hummer? More importantly - has anybody found a good quality after-market peg that fits the Hummer (preferably oversized)?

    Yep - the bike still goes as good as day1. I'm spending more time abroad now though - so only get to ride the Hummer once a month or so. Even so, I give the bike a good work out - but always make sure to drain all fuel out of the tank and carbie before leaving it in the shed for any time...

    I'm not sure what gauge chain that Honda takes mate - it could well be a 520. Also, the machining for additional bolt holes has to be spot on - or the sprocket wont run true. If you can't get service from SNC - I'd buy one from Atomik. They do nice sprockets in both 48 tooth and 52 tooth -...

    Hi Johnny 1 You divide the number of teeth on the front sprocket into the number of teeth on the rear sprocket to work out the sprocket drive ratio. If you have a 16 tooth front sprocket and say a 48 tooth rear sprocket, that works out to a D/R of 3:1 If you have a 17 tooth front sprocket and...

    Hi Johnny#1 Yes, the sprocket will fit just fine. There are a couple of notes however, 1. You will have to extend or remove the chain roller from underneath the swing arm, or else the chain angle will be too steep. I've now removed mine and it hasn't caused any problems. 2. I'd also buy a 17...

    Hi Cujo, You may have just had some water condense out in your carbie whilst the bike was laid up. If not, a new 250 Zongshen head gasket is available from just about anywhere these days and changes over with no hassle. If you don't have the torque for the head bolts in your owners manual...

    Hi Mate, You can order them mail order from here. Saturday Night Cycles Home Be sure to give them the specs for the chain size and sprocket mounting holes - since they sell a lot of different models. I'm currently using a 17 tooth front sprocket and a 56 tooth rear sprocket (purchased from...

    You need to get yourself a rear shock spanner and tighten down the spring. Loosen the top lock-ring first - then tighten the bottom ring to compress the spring. Don't tighten down more than a three full turns - otherwise you are exceeding the disign parameters of the spring. Once it's adjusted...

    Yeah - it quite easy - though be prepared to stick your fingers in your ears when you start her up! Also, the amount of exhaust back-pressure will be changed slightly - so you may require some carby adjustment or re-jetting to get the power band dialed in to optimum. There are heaps of...

    Atomik should stock them - although the Mikuni Carbie and engine on your bike is pretty standard for most China 250s - so most of the China bike stores will carry them.

    Dirt bike registration- illegal riding

    Yeah we do OK over here really. The web site below is the WA trail riders association. They got a state grant to try out upgrades to trail surfaces etc. Recreational Trailbike Riders' Association WA Their site is a good read and gives some info about what's going on and where to ride.

    Dirt bike registration- illegal riding

    In WA you don't need any road going gear (lights horn mirrors etc) to get off-road vehicle registration. You just fill in the application form which asks for the bike make, model, serial number and colour. You sign a declaration to say the bike is safe to ride and complies with noise output...

    Dirt bike registration- illegal riding

    Hi 370, Over here in Western Australia you can get off-road registration for a dirt bike or quad, which costs around $12-00 per year and is issued by the same place that does the road registration. The state government has made a number of designated off-road recreation areas available, where...

    Going to try the new Hummer G4

    Hi guys, been offline for a while with shingles. Take my word for it, you don't want to get them! Over here in the west, most of the ride areas are really soft going and it can be a real bugger staying upright in soft sand. I just fitted a set of Motos Tracular tyres this weekend and I...

    Yeah the drz 400 looks good performance wise - but I just don't like the concept of a liquid cooled bike - I'm just getting old & grumpy I guess! True the DR650 is getting a little long in the tooth now, having been in production so long - but there can often be benefits to buying a bike...

    Going to try the new Hummer G4

    I've read a fair bit about them - but from what I can tell they're not much different to the standard hummer or similar. I think somebody just went the extra step and had some mods done - then did the legwork to get them compliance registered. If you're looking for a recreational bike that...

    Let's just hope they take the extra step when they put it on the market and offer a dual sport version you can register for on/off road!

    I'm hearing rumors from the States about a 450cc version of the Hummer being put on the market next year. Anybody else heard anything similar?
