What is the valve clearance on Suzuki GN 125


Hi, Robbie for this scenario you will need your service/owners manual if you can't find the first and best tool you ever bought for your Suzuki, despair not, for a mere $10 you can download another one. For more information about your issue and valuable "FREE" downloads that you will need please click on the links below. Good luck and have a nice day.

What are tools required/procedure for adjusting tappets?


A good feeler gauge set and a basic set of sockets, wrenches, and a screw driver set will work for most engines. I hope this helps. Rod
Now first you check the clearance and record the clearances. If they are out you need to change the valve bucket (which comes in different sizes). This involves removing the camshaft to change the buckets and then reassemble and recheck the clearances. This is a big job and dealerships will often charge $1500 plus to do this job. I am going to post some info from a thread which will explain further. Many motorcycles are similar as well.

The general procedure for checking and adjusting the clearance based on having done this on bikes is;
Before removing old belt
Measure and record each intake and exhaust valve clearance using feelers gauges. Use the crank rotation sequence and measurement order listed in the manual, else you may get erroneous readings due to cam journal clearances and the valve springs pushing the cam around in the bearings. Some are not measured on the exact base of the cam (i.e suzuki)
Compare the readings to specification
If any are out of tol, calculate the difference between the reading and spec.
Remove the camshaft with the out of tolerance readings (usually both if one is out of tol).
Record the markings on the bottom of the buckets that are out of tolerance. (I usually like to measure these with a mike to verify markings and or determine if there is any measurable wear and adjust accordingly)
Refer to the list of available bucket sizes (from svc. manual or dealer parts counter)
Add or subtract the difference you calculated above to determine your new bucket size. (bikes typically tighten up so you end up going with a thinner shim, er bucket)
Order the buckets needed (sometimes you can swap them around between locations to minimize the qty needed to order).
Install new buckets in the proper locations.
Re-install cams, new belt, new tensioners, and new Idlers.
Repeat measurement process from above.
If measurements are in spec, you are done.
If not, repeat.

Last winter I checked the valve clearance on a 2001 Focus ZX3 with the 2.0L DOHC engine. It had about 85K on it. The clearances were all pretty close to nominal. I don't know the history on the car since new so they may have been adjusted at some time in its life. IIRC the interval for that car was 75K.

As I said above, bikes typically tighten up with this type of valve train. This is due to the valves seating deeper in the valve seats due to wear. This increases the installed height of the valve, decreasing the clearance to the cam. The rate of seat wear exceeds all other wear causing them to tighten.

Tight valves are worse than loose valves. Can eventually lead to low compression, and burnt valves.

If the wear of the cam, bucket, cam journal exceed that of the valve seat, the clearance will increase.

I don't know what the general trend on these engines are as far as tightening or loosening, but if they are like a bike, they will tighten.

I can tell you that on bikes if they are operated a significant amount of time near the red line, they will require more frequent adjustment compared to one operated more conservatively. A bike that is operated conservatively may not need any adjustment at the first inspection interval (not unusual for my Yamaha FZ1, 26,000 mile interval)

Sorry about being long winded, but I thought I would do a brain dump to help people understand the process.

I hope this helps. Rod

Personally i would check and see if you have any water in the carb before anything. this seems to be a common prob.

Valve Clearances inlet and exhaust


j24b engine D.O.H.C.
U.S.A?
open hood , look up. see white sticker, see clearances.?
off online F.S.M
Valve clearance specification when cold :
59 to 77deg F or 15 to 25deg C (engine temps)
Intake: 0.0063 to 0.0094 inch (0.16 to 0.24mm)
Exhaust: 0.0123to 0.0153 inch (0.31to 0.39mm)
you must remove the bucket,tappet , to change lash.
MIKE IT (that means a micrometer)
then buy shims or new buckets to fit. (generic answer)
the book says buy correct tappet after measuring, yours.
and it's out of range, and doing the math first.

that is it.

I hear a ticking/rattling sound somewhere in or around the engine of my 2006 suzuki Forenza. The faster the acceleration, the faster the sound seems to be. Any idea what would it be? This is my first...


Sounds like your valves are knocking. They can be adjusted pretty cheap.
Or you could do it yourself. Basically you drive the car to get it up to normal
operating temperature, then remove the valve cover and use a feeler gauge
to measure/adjust the clearance between the rocker arm and the camshaft.
You would need to know the proper clearance clearance.

If you get a Chiltons manual for your car at Oreillys, it tells you how to do it.
And it tells you the clearance you need that i mentioned before.

But an engine/head shop should be able to do it for a reasonable price.

I need to know the valve adjustment procedure and


Valve clearance ideal setting is 0.10mm however as ideal replacement size shims are not always available use tolerance 0.05 to 0.2mm inlet and exhaust Procedure remove tappet cover rotate motor to tdc compression (inlet valve lobe pointing to rear wheel and exaust lobe to front wheel) measure clearance if no clearance depress cam bucket hold down by wedging a screwdriver or suitable tool (allen key) between cam bucket and cam remove shim measure with micrometer an relace with a shim 0.15 thinner depress valve remove wedge and measure clearance (if any) repeat procedure 4 each cylinder if clearance to large replace shim with a thicker one till clearance is in spec

What is the right valve clearance for a 1979 suzuki gs850 i had to replace the head and cams but the shims are not in the head how do i check the clearance and at what cam position do i check them at


You need to put the shims in and fit the camswith all the caps and bolts on.
Then measure between the cam lobes and the shims with a feeler gauge, when the cam lobes high point is away from the shim bucket.
and write down all the measured clearances.
Then remove the cams and fit the correct thickness shims to get the clearance correct.
Fit the cams again and check, this can take a couple of tries if there were tight clearances in the first instance.
either fit the cam chain up each time to do both cams or make sure the pistons are only half way up the bore and do one cam at a time, to make sure the pistons and valves dont say hello.
cant help with exact clearance but a kawasaki 750 is 3-7 thou which will be pretty close as the shims let you adjust 2 thou at a time
ie if the measured clearance was 2 thou you would need a thinner shim to adjust the clearance to 4 thou

Valve Clearance


valve clearance, with engine hot, intake valves are .005-.006 in, exhaust valves are .011 in, if engine is cold then its intake .009-.011 in and exhaust is .007. hope this helps good luck.

Valve timing check


Chain drive. Unless the engine's been apart, why would the cam/valve timing change?
Valve clearances are another matter, and unless you want to remove the camshafts, get a mechanic who has the proper Suzuki tool to do them for you. You can measure the clearances, but the shims are between the cam lobe and the valve bucket, and the special tool holds the bucket down whilst changing to a thicker or thinner shim.
