Well Bruce it seems as though Honda may not be all bad towards the two stroke like has been thrown around here from time to time. This link was written in 2003 when all the two stroke shit started in the states. It seems maybe Honda was being pro active or looking at different avenues? Fuel injection may even be old hat in two strokes it seems, maybe the euro guys can market it as they are first
Interesting regarding the emission from a two stroke “they produce more harmful carbon monoxide and hydrocarbon emissions than four-strokes, putting them outside the realm of on-road emissions laws in America, and outside future requirements of other countries” maybe thats a FACT and why in California (the toughest emission state in the world) two strokes are banned. Maybe not because one manufacturer wanted them gone and slept with the government as some people argue.An interesting article none the less http://www.motorcycle.com/manufacturer/honda/honda-exp2-14293.html
Honda also ran the same bike in the Dakar which should surely help put paid to the excuse my two stroke isnt any good for long rides.
Anyone seen pics or the KDX250 Michael Goddard used to finish third in the Australian Safari ?? Third on a smoker

Yeah I dont know Roy the problem does seem to be the unburnt fuel. I read somewhere recently that the new low emission two stroke outboards are helped out by the fact the exhaust is washed through the water (the exhaust exits into the water) and thats the only way they can meet the emission laws
Its interesting for sure
Here is a picture of it in Dakar

Fuel injection will help it atomise the fuel and oil better in the cylinder for burning and that’s it, it’s the unburnt hydrocarbons that are killing the two strokes in the emission ring. The same problem killed the two stroke Detroit engine and when the emission laws tighten because of the greenies well
My fuel injected Tenere is soooooo much better in fuel than a carby 660 Tenere with a slower rider than me so I have to say you are fishing for an argument or well, lets say you are fishing :laugh: :laugh:

what one of these motorcycle companys need to do is put some of Ralph Sarich orbital engine designs into practice and reinvent the 2 stroke as the technology is there with original designs that in 1972 developed a stroke motor that was 50% lighter,30% more fuel efficient, 20% cheaper to make70% smaller and 30% less pollution we are now nearly in to 2011 and as was said in one of the current magazines that some of the motorcycle companys are looking at this design showing a motor with more power , more torque, lighter and also it wouldnt need an expansion chamber anmd could just run a normal pipe. So dont be 2 cocky all you 4 T lovers 2 smokers will be back smaller , faster and lighter
