I have seen the inside of a lot of engines and Beta impresses me for several reasons. Durability, maintenance friendly, and they run soooo smooth. Look at the size of that filter! Twice the size of any KTM filter. Plus the trans is separate from motor oil, AND the pick up screen is built onto the drain plug (how awesome is that!).

Thanks for checking out our video! Hopefully yours looks just as good as these ones! Enjoy the ride, Jared

Great content, many thanks. I checked my valve clearances at 60 hours and found both inlet are of of spec. I have measured my shims with a Vernier calliper and also a micrometer. One of the shims has 2.575 written on it but measures 2.560 with the vernier and 2.508 with the micrometer. I put this down to the wear of the head of the valve stem and the wear of the follower against the shim. The vernier cannot measure the wear of the valve stem against the shim, whereas the micrometer does.

Thanks for the vid, I just did mine using this video as a reference. Wouldn't have felt confident without it. Was easier than I expected. I left the cam in, and just lifted them and the follower, and used a magnet to fish out the shim. Thanks for the tip on the bearing position (behind the gears). Wouldn't have realized that it's important. I think my exhaust bearing wasn't seated properly (all the way back) when I opened it up. Any tips on inspecting or servicing the exhaust decompression mechanism?

So you don't lock the cranckshaft with the special bolt ... old school which works well too ;) Speaking of old school, the stick in the plug hole to get the highest piston point is a good trick too ;) ( but if caring to have the real up piston timing of course ) THanks for the video. clear, good speech. Good job !!! kudos !!!

Thanks for the comment! Good question with the crank shaft lock. There is one on this bike, all you would have to do is pull the skid plate, unscrew the hex head bolt and take the thick washer off then reinsert the bolt once the bike was at TDC. I typically only do that when I'm doing a full engine rebuild. I always mark the timing chain and cams with a marker so I can make sure it goes back together exactly as it came apart. Also the screw driver down the spark plug hole is a good trick as well. If I couldn't see the cams to know where I wanted them then that would of been helpful!

Once you had the intake done, put the cam chain back on and then take the cam chain off the exhaust. I just like to keep the chain right where it needs to be during the whole process. You will do the same exact process with the exhaust, they use the same finger followers and same shims as the intake. Thanks, Jared

What do you think? On the other hand, the question about the shims meant that if it is possible, for example, one of the exhaust valves needs 2,400 mm while the other one 2,425, or the normal thing is that both thickness are the same.
