I appreciate that. We're big on pressure washing them (@ low PSI and not the chain!) after a romp in the mud and dirt. We run them quite a bit around on the old farmstead, which is mostly a lot of grass and weeds. When the vegetation gets taller, we usually end up with green footpegs, levers, and forks!
Takes a bit of de-greaser and elbow grease with a stiff brush to get that stuff off, believe me.
You can't go wrong with a few Honda air cooled thumpers...
You got that right! These rugged four-stroke singles remind me of little tractors or draught horses...plenty of low-end grunt. It's like they just lower their heads and pull harder on their harnesses when asked.
