What? say it isn't so!!!!! but this may work out to be in our favor! when people realise how good they are they will be worth 10X as much and will be a collectors item and we will all be RICH.
Well it's official - I got an answer from both Atomik & Dreamrider to say that the Hummer G4 is temporarily off the market, awaiting the release of a new model.
According to Atomik - the new model will have an optional lights kit!
Release is set for Spring/Summer - so there's a bit of a wait!
Hmmm - I wonder if this thread has made the Hummer too popular and they're getting more money by only selling to retail? I notice all the Hummers for sale in shops have either the Atomik or Tomahawk Import brand - rather than some generic import graphics.
The specs look great - although it's strange they have changed over to a Loncin 250cc OHC engine.
15.5Kw is starting to get useful on a stock engine though - and all the fruit looks as good or better than the previous model - plus of course you get the lights!
Only three questions boys! How will it perform - what will it cost and who's going to get one first Ha Ha.
hi guys just seeing if someone can help me out i have a hummer 250 and i have put a 1.5mm main jet in it with a pod air filter and a hotter plug but now i have good power down low but when i get up in the revs it is braking down like it is runing out of fuel or spark is braking down it is not over fueling because there is no smoke at all its more like it is leaning off i was thinking that now the float level might need adjusting to keep the fuel up to it as well when i free rev it i can hold it flat out and it don't rev all the way out the same time i picked up on this i was in a lot of wet mud and water the bike was covered can some help me with some ideas on what might be going on with it
Mate you've got a lot of new stuff going on there all at once - which always makes it difficult to diagnose faults.
The first thing I'd do is go back to the original plug - just to eliminate one of the variables.
If a bike runs rough at high revs, the mixture is usually too rich. You will notice this effect if you leave the choke on when the bike is hot.
Depending on where you have set your carbie needle, you can try adjusting it to make the mixture run leaner or richer (as the case may be).
If that doesn't work, you need to check that your new filter is letting the air through O.K. Be careful when applying filter oil - using too much can restrict air flow.
At the end of the day, you can always have your carburation analysed on a machine - which will give you a definitive answer for only a few bucks.
At the end of that process, you may discover your new jet isn't optimum for the current set-up - but at least you will know!
Once you get your fuel/air mixture working and the engine running O.K. - then you can try a high performance plug
The rule is - one change at a time - optimize performance after each change.
Hey Guys
I have noticed some people asking about jets,
I replaced the secondary jet in my Kuda pro when i replaced the muffler with the carbon fibre pipe and i just took the jet as a sample to my local bike shop which is easy as the carby is a Mikuni nock off! so in this case i went to a 110 on the secondary jet, after my crash i got a new double covered pod filter off eBay and i put that on the bike and it was lean as hell so out came the carby again to replace the primary jet which started off as 39 standard, again visited my bike shop and with the old jet as a sample i got a new one but the shop only had a 42 and a 48 so i got both and after putting the 42 in i found this jet gave me the pefect tan colour required.
So i just can say take your jets with you as samples but any bike shop should be able to help as the carby are Mikuni nock off's
