Spark knock isnt always audible either, when it occurs the gasoline is exploding rather than burning. What can happen?
Blown head gaskets
Cracked pistons
cracked piston rings
Damaged Connecting rod bearings, rod bearing damage is the most common with knock but not always noticeable until later...
For anyone wanting a spare tire for their FL5 This has to be the best option. I just finished installing this kit and I'm totally satisfied with the results! Price from my local Honda dealer was $375. Beats trying to make other stuff work, If youre on the fence about doing this dont be.
I've been thinking about removing my engine cover as well, It'll look new when you sell someday. dont think it'll hurt the paint. what size screws did you use?
