2012 Kawasaki VN 1700 Voyager sounds like a valve tap coming from Engine. It will go away after riding and warming up. Is it a valave tap or something else?


Hi,the sound you are getting is normaly to do with the camshaft cleerance between the camshaft lob and the shim on the valve,if when the sound gose away when the engine is hot its the gap getting smaller due to exspantion,I would leave it unless you can hear the sound when engine is hot,if you cant live with it the whay it is the only way to sort it out is to get a works manual and do the valve cleerances,which means takeing the rocker cuver off and checking the gaps between each lobe and shim and replacing with the right shim to make the gap right,hope this was some help.

Seat post shim


Hi, 27.2mm is a standard size for a seatpost, popular sizes includes 30.9mm om newer mountain bikes and 31.6mm on older since it stadardized to some extent. There are still many other odd sizes out there on mostly older bikes.

If you can, get a seatpost that is 27.2mm that fits directly into your frame, with no shim if possible. that will only add weight and creaks.

Also keep in mind that the length is important when you specify a seatpost. You can use websites like this to see what is possible/available before you order:
Seatposts Chain Reaction Cycles

You will also have to consider if you need some setback, if the seat clamp is directly on the post, it is called a zero setback post like this:

How do i do a valve adjustment.


With shims. Hotcams.com shim kits. Or bikebandit.com

The shims are under the buckets that the cam lobes are on top of. You will need to have feeler gages. What issue are you having with the bike? Are you sure it's valve related.?

How do i adjust the valves on a 05 klx 125


I'm not 100% sure on this particular bike, but most late model hi-perf japanese bikes have shim adjustment. You can tell if you take the tappet cover off & the cams run straight ontop of the valves, If it's shims, you need to turn the motor until the cam lobes (pointy parts) face as opposite to the valves as possible (usually upwards) so the valve is completely shut, then use feeler gauges to me asure the gap between the valve tip & the cam. The valve springs can be compressed slightly (carefully) to let the shim on top (or underneath) the bucket be removed & replaced with the right thickness to give factory specs. Sometimes one shim from one valve can be used to make another valve correct, leaving less shims to buy. If not shims, should have a simple screw & locknut adjuster, same setup, just measure between valve & rocker, adjust to factory specs (or slightly smaller for more go)

Bike starts fine on choke then ticks over when choke off. within 2-3 mins the revs decrease to the point of stalling. have adjusted tick over to around 900 revs but as soon as engine warm the problem re...


If your bike has ever sat for more than a few months at any time, the carburetors could be plugged with gasoline residue. If so, they will need to be disassembled and cleaned.
Otherwise, make sure all of the normal tune up items have been performed; valves adjusted, air filter, spark plugs, etc. And make sure there are no air leaks between the carburetors and the engine.
Finally, if the above things are all good, then I would perform a compression check. With the throttle held wide open, you should see at least 140psi of compression, on every cylinder. Anything lower than that will cause an erratic idle quality and overall poor performance.

Are the valves adjustable on the 1990 3.0L? I


1) The valves are adjustable, but they are of the shim-type adjustment. You will need to obtain the proper shims from a dealership parts department.

2) Any Toyota dealer can, by you giving them your VIN, tell you whatever was done to the vehicle under warranty

3) There are no special service campaigns for bed replacements, nor has there ever been one. Any bed that 'was' replaced was under factory "goodwill", to maintain customer satisfaction.

Engine ticks


You need to get your valves adjusted. When an engine is new, all your parts are not worn. As time goes on, mechanical parts break down. your valves are riding on your camshaft, and eventually wear down. You need to re-shim your valves to maintain the clearance that it had when it was new. You can do it yourself, but you are better taking it to a mechanic. They have the right tools. Shouldn't cost too much. This is a common procedure. Dirt bikes have this same problem, mostly because of the high RPMs and engine break-down is more rapid.

I need to adjust the valves on my Suzuki rm-Z 250. Can you tell me how?


To adjust your valves you will need a few standard tools and most importantly a set of feeler gauges. You can buy these at any automotive store. The first step is removing the tank and valve cover to gain access to the valve train. You will see both the intake and exhaust cams plus the tops of the valves. This is where you will be measuring with the feeler gauge. The next thing would be to rotate the motor to top dead center. You will need to remove both inspection covers that are on the side of your ignition cover. This will give you access to the timing marks and to the bolt that allows you to turn the motor over.

Check in your manual as to what direction to turn the motor over. You do not want to turn the motor over in the wrong direction. Turn the motor over looking into the inspection (top) hole. You will notice a mark on the fly wheel. When you see this mark come around, look up at the cams. There should be two punch marks on the cam gears that line up with the gasket surface towards the outside of the head. At this point you should be at top dead center compression. Check the lobes of the cam, they should not be touching the valve buckets. If they are touching the valve buckets, this means that you are 180 degrees out of time. Rotate the motor 180 degrees and then start to measure.

After you measure the clearance between the cam lobe and the valve bucket, you will want to write that down. You will then need to check your numbers against the spec's provided in your service manual. If you are outside the specified range, you will need to remove your cams and replace the shims. There should be a chart in your manual that will help you to decide what shims you will need to bring you within the safe range. When dealing with the KXF250 or the RMZ 250, you want to make sure you use the correct shims. There are two types that will fit these bikes, but only one is the correct shim. Shims come both forged and sintered. They look the same until you put them under a magnifying glass, then the difference is very clear. The forged shims have a smooth surface, while the sintered shims have very small cavities. Using the sintered shims will prematurely wear the coating off of the valve stem. This will shorten valve life and cause the valves to go out of adjustment sooner.

Now, after replacing the shims, all that is left is to reassemble your machine. Pay closer attention to the instructions in your owners manual. Always double check your cam timing with what is recommended in the manual. Do not start your bike without turning the motor over by hand first. If you feel it is unusually hard to turn over or it will not turn over, you probably are off on your cam timing. Once again, do not try and start the bike. Go back and retime your cams.
