How to adjust tappets

You have asked a very big question. Adjusting the tappets is another way of saying adjusting the valve clearances.

Lots of engines these days are fitted with hydraulic tappets that are self-adjusting. Some engines are overhead camshaft types with bucket tappets and the clearances are adjusted by measuring and selecting different thickness shims. The shims are sometimes under the bucket and sometimes over. The former is a fairly big and complex job to adjust and the latter is fiddly and requires much patience.

Traditional designs using adjusting screws and locknuts exist on all manner of engine types and once the principle of which one to adjust when is learned, these are relatively straightforward.

I strongly suggest you discover first what sort of tappets you need to learn to adjust, learn something about the way the engine works and why the tappets need periodic adjustment and then pay somebody to show you how to do the job so next time you will be able to do it yourself.
Adjusting the tappets is one of the core skills of the mechanic and it is learned better by demonstration and understanding than from a book. No book can adequately describe when a feeler blade has a good or a bad "feel"...

Good luck!

MOVE EACH CYLINDER TO TOP DEAD CENTER OF COMPRESSION STROKE ( sorry caps on .) check that timing mark in timing cover hole is in line .remove adj cover per cylinder in alignment and adj valves according to mfg specs. to adj : under adj cover , loosen lock nut on top then loosen adj nut on btm @ top of valves . insert feeler gauge under rocker and adj ,this is tricky to say the least. usually takes several tries to get it right, keep trying the valves must be set right or major expenses can be expected to occur. intake and exhaust settings are different normally at least .005 .be sure to tighten locknut on top before checking if clearance is correct. holding the btm nut while turning the locking nut is the tricky part 4 me anyway. 2 valves per cyl. on most atv eng. adj all valves .start eng and listen to eng w/o reving up. any ticking noise and you get to start over. should be smooth idling and quiet. no popping or backfiring. smooth starting and off w/o run on. should not be performed unless you are familiar with the procedure. contact me or service center near you if not sure on procedure.correct adj. is slightly snug fit . valves making no noise when done .

What is tappet settings

Hydraulic tappets are tappets that contain a small hydraulic piston, pressurised by the engine's lubricating oil supply.[5] Although the piston does not move appreciably or frequently, it acts as a hydraulic spring that automatically adjusts the tappet clearance according to the oil pressure. This makes the valve actuation self-adjusting and there is no need to adjust the rockers. Hydraulic tappets depend on a supply of clean oil at the appropriate pressure. When starting a cold engine, with low oil pressure, hydraulic tappets are often noisy for a few seconds, until they position themselves correctly.

Loose drive chain

You have a big nut on one end of the axle, and the 2 adj screws on either side at the end of the fork. Loosen the nut, tighten the adj, if your bike doesn't have marks on it, make some now before you move it, then move no more than 1/8 inch off the mark you made. Tighten up the axle, you are all set, the chain should have a little slop to it, 1/2 min, Hope this helps.

Valve timing marks

Valve adjustment is performed with the piston at top dead center (TDC) of the compression stroke. On the flywheel, there's a "T" mark that indicates TDC. Align the "T" mark and check that all of the valves are closed (this is where they must be to check and/or adjust the valve tappet clearances). If they are not closed, rotate the crankshaft one full turn, aligning the "T" mark again. Now the vwill all be closed.

Before adjusting the valves, 1. check the oil level 2. use an engine cleaner that you add to the oil (berryman's or equivalent) and run thru the engine for 30 minutes 3. change oil and filter 4 run and check for tappet noise. This may improve things without opening things up.
