Just have to remember to clean the air filter regularly.

The record was a 372 in from France with the massive fault of....a dirty air filter!

It is about time people purchased air compressors!

I've had a look now and it seems saws over 50CC have to produce 2/3 the CO of saws under 50cc as of now,. Any new saws for sale now would have had to have been testes a year ago, so that suggests the time lag.

 

I wonder if we are seeing the same as cars, when carburettors were unable to meet emission limits about 20 years ago and injection became universal (a good thing IMO), and injection is the only way to meet the regulations, not because it produces more power  but because it meters in exactly the right amount of fuel throughout the range, whereas carbs are okay at tickover and full load but a bit out in between.

 

Oddly the bigger stage 5 2t engines will be able to emit about 33% more HC+NOx combined than smaller ones per kWh.

 

I always thought the issue with 2t engines was HC and NOx, the HC from fuel and unburnt oil carried over and NOx from running a bit weak. Whereas out in the open carbon monoxide isn't much of a risk, is not a greenhouse gas or a precursor of particulates.

But ! We only USE them at tick over an full bore ! K

Yes they are only designed for that but operate outside these two states at times. Anyway the point is injection should dose the air:fuel mixture more accurately than a carb can.

I missed out on a mint ZX7RR homologation special about 10 yrs ago, i fancied that to be a bit of a weapon, but looking back compared to now a days it probably wasn’t owt too “special”
Loved my 1200 Bandit for the hooliganism factor, and loved my Mille RSV-R for the raw punchy factor of the v-twin.
