At F2 Motorcycles Ltd we still hear from people who have set their tappet gaps according to the factory handbook. They usually complain of lots of noise coming from the right hand side of the engine. So here is the F2 Motorcycles Ltd guide to setting the tappet gap.
The factory handbook instructions require the tappets to be set at top dead centre using marks on the flywheel. This system assumes that the lowest point on the camshaft is machined exactly to correspond to the position it is in when the piston is at top dead centre. A fair assumption, but unfortunately in the case of Ural it is a completely false assumption. The method and settings we use at F2 will work on all Ural 750 OHV engines. The same method but with different settings will work on every 4-stroke engine I have ever come across.
It is so simple.
