If the noise disappears often, then the noises are merely a result of the engine’s operation. The best way to diagnose this problem is to inspect the bearings bearing failures can deteriorate in a relatively short period. In severe cases, maybe the bearing has failed. However, if this noise persists irrespective of engine temperature or load, it may be a sign of imminent bearing failure. This noise is due to the XV1600’s engine design and is normal. Knocking noise from the crankshaft areaĪt low speeds, you may hear a somewhat subdued knocking noise from the crankshaft area. If the piston inside the hydraulic lifter is scratched, then the lifter will not contain the compressed oil inside to make the valve/pushrod.Ī damaged lifter will need to be replaced. Constant tapping could be due to a part known as the flat-lifter.
However, Continuous tapping in the camshaft is not normal. It’ll need a few minutes for the air to spurt out of the lifter and self-adjust to proper clearance. Upon restarting the motor, a small quantity of air may enter the lifter. The push-rod rests in a position where one of the valves is open when the motor is killed, and because of pressure applied to the lifter by the valve spring, the lifter will flow down over time. The tapping is caused by extra push-rod clearance while it waits for the hydraulic lifter to be pumped up. This noise should subside as the bike reaches operating temperatures. It is normal for you to hear a tapping sound from the camshaft area while the bike warms up.
The opposite side is adjustable and must be fixed, so the valve junction point is the same as the other side, or it will create that unconventional ticking noise even when the bike is cool. One side of the rocker is nonadjustable, and the margin is self-adjusted by the hydraulic lifter.
#Rodstar o series#
A single rocker controls the opening and closing of both series of valves. However, hearing a ticking noise when the engine isn’t hot may point to improper valve clearance adjustment.Įach cylinder in the engine has two intake valves and two exhaust valves. The cylinder heads’ air-cooled nature means some ticking is inevitable, especially as engine temperature increases and parts start expanding. Ticking noise from the cylinder head area Let’s take a look at a few of the sounds in question: i. Some are actually signs that something is out of place or in need of replacement. That said, not all the noises on these bikes are normal. This makes that users experience some weird noises during either idling or riding. Unlike their liquid-cooled counterparts, air-cooled engines do not have a water-filled jacket that dampens engine noise a wide-opened, finned v-twin motor lets its roar loose.
