Hi, Is there a way to tell if the tappet inlet is too tight without disassembling ?
Can you tell this just by looking at the mark on the magneto rotor through the inspection hole? Thanks

Sorry but you have to physically measure it. Checking the valve lash entails removing the fuel tank t gain access to the tappet cover, removing the cover etc. Did resealing your air box help?

Ok thanks for your answer.
I still do not solve the air leak because I do not know how to do it.
I do not know how to seal the air box, do I have to disassemble everything or is it enough to remove the side covers and the seat?

The air box is supposed to let air in though the snorkle or air inlet, if you think the airbox is leaking on the engine side, you should be able to get a good look at things by removing the air filter access door and peaking around with a flashlight. You shouldn't have to remove more than the seat and left side cover to get that far, and I'm not positive you have to remove the seat.  I think the owners manual details the operation, you can also find the correct parts page on the Hitchcock's web site which might help.  I wouldn't worry about the valves or anything else until you figure out if you have an air leak.

God l remember the old brits when they has inspection mirrors you could check your tappets, now its tank off inspection cover off, all on the job time, mind you if you don't do it that valve could burn out you would have a much bigger problem, head off, new valve, gaskets, a great deal of time and labour.

          It's obvious you need to get a book that covers motorcycle engines and how they work and maintenance and  then a book that covers the Himalayan engine and the whole bike and do some homework. 

           It's not tappet inlet, it's inlet tappet.

It's a simple task, setting the tappets. One of the niceties of the Himalayan is its simplicity. Plus, there are lots of u-tube DYI videos to be found for learning how to do these things of you don't want to follow the manual.

Once you've done it the first time, the next time it'l be really easy.
