Could be one of two things
1--broken ring --- burning oil from scored bore
do a compression test
2--- big end bearing failing--- overloading the oil control ring
use a mechanical oil pressure gauge to check idle oil pressure
take it to a service dealer for a proper diagnosis

2012 ninja 250r cam chain tensioner cleaning


Never heard of the cam chain getting dirty. There is a mechanism on the front of the engine to tension the chain on that bike I believe. I would try tightening the tension a bit to see if that will help.

Bike has annoying ticking noise from mostly rear cyl..bike is a 2000 shadow spirit, with 33000 miles, i was told valves needed adjustment at 30,000 miles , along with timing chain adj.. is this correct?


Without being able to stand next to the machine and listen it would be very hard to say what the noise is. Valves are generally easy to adjust and if loud have a high pitched tick sound. Cam chain adjusters generally self adjust and are reasonably quiet. If the automatic adjuster goes bad it will generally make a clatter sound or a loud clack. One thing you have not considered, if the the exhaust gaskets in the head go bad or leak air, they can also produce a loud ticking sound. You often hear this sound in older V8 engines. It sounds like a lifter is bouncing around inside the motor but the sound is caused by a blown gasket between the head and exhaust manifold. If you experience some popping/backfiring during deceleration try replacing your exhaust o-rings in the heads. This may solve both problems. If the problem is internal to the cylinder you may need to change a bad cam chain adjuster. As always start with the cheaper fixes and work your way up. Adjust valves and cam chain tensioner if not self adjusting, replace the exhaust gaskets next, and if that does not fix it, replace the cam chain tensioner. Hope this helps.

Hi I am doing a simpile head & cylinder inspection. Just bought the bike smoking bad. The cylinder & piston are damaged. I will be replacing piston rings & doing a bore job to match new piston....


The diagram below should work for you. Put the piston on TDC. the OHC cam gear will have a single mark or may have two marks, see below. Be certain the front side of the chain is taut when mounting the gear. The cam chain tensioner keeps the back side taut.

On my 1.8 volkswagan passat AWM engine,the camshaft drive chain tensioner is knocking,the engine has plenty of oil reaching the top,and the engin runs good.what would make it knock so loud?


I bet your car sounds like a diesel without the gas savings benefits. Your only solution is to replace the cam tensioner! Call VOA to complain about the manufacture defect.
