Can a counter balancer be used in a two stroke engine?
However, now that KTM has refined the design and size of the counter-balancer shaft (through its development on the four-stroke range for many years), it became physically possible to integrate the balancer shaft into the 2017 250 and 300cc two-stroke engines in a way where the advantages outweighed the disadvantages,” Twyerould went on to explain.
Are there any dirt bikes that have a counter balancer?
So, as far as we’re aware, KTM’s all-new 2017 250 and 300EXC models are the first two-stroke production dirt bikes that have ever been fitted with a counter-balancer. Interestingly, KTM was also mucking around with two-stroke counter-balancers in the mid-1990s.
Why does a KTM MX have a counter balancer?
Michael Viertlmayr, who heads up the engine department for KTM’s MX and enduro models, sheds more light on the design’s history. “Like introducing any new rotating mass into an engine, a counter-balancer adds friction and therefore robs the engine of some power,” Viertlmayr explains.
Why does the Honda J35 have a smaller crankshaft?
These engines are a V6 and were designed to be transversely mounted. Not only do they have shorter bore spacing, but they also have shorter connecting rods. These engines also have a smaller crankshaft than the C-series. The reason the crankshaft is smaller is to make the engine smaller altogether.
Can a counter balancer be added to an engine?
“Like introducing any new rotating mass into an engine, a counter-balancer adds friction and therefore robs the engine of some power,” Viertlmayr explains. “Plus it’s expensive, and it’s not easy to integrate without making the engine’s dimensions bigger.
What kind of engine does a Honda J35 have?
Mounting a V6 transversely can be difficult so Honda took as many measures as they could to decrease the size. All of these engines are SOHC 4-valves per cylinder and have VTEC variable valve timing. While this engine is installed in cars from other manufacturers, there are quite a few Honda models that have this engine installed in them.
Why does my Honda J35 make weird noises?
There are reports online have the VCM system causing noises, vibration and/or shudders, excessive engine sludge (although this is probably due to poor maintenance), and abnormal oil consumption.
