The Major Pluses to this engine and it's configuration are a few
Less costly Maintenance, I do my own maintenance, but it is easier for me to do at home on this bike.
1. Only one Throttle body, no need to Sync fuel injection that's money saved in Maintenance, thanks Honda
2. No Shim under Bucket Valves, instead Honda uses screw & Nut configuration Thank You Honda, But they should have used Hydraulic lifters for No adjustment but probably cost more
3. Major friction reduction fuel economy and smooth engine
4. Longer interval 8k Miles, instead of 3k, thank you Honda
In looking at my Honda Service Manual for my NC700X looks like this bike was and is designed right, the engine does not have to be pulled because the lousy engineer put something at the back of the engine, it fails then you Must pull the engine to replace it, I dont see that, with this new engine, Unlike my various Goldwings, stator goes out pull the engine, clutch goes south pull the engine, ignition part pull the engine.
The CTX & NC 700's those items are on either side of the engine/trans and can be pulled while the engine is still in the frame, thanks Honda
