You didn't say WHY the cam / valve timing needs to be reset. For some reason I get the feeling someone told you that resetting was needed and so you are asking how. Obviously, you may have installed new pistons and that is why the resetting is needed. In either event, when the cam timing is set the valve timing is also set. Other than adjusting valve lash, setting the cam sets the valve timing. Below is a web site where you can do a free download of a factory service manual. The process is not hard but having a manual will be more help and faster help than I can give online.

Back the screw handle out so the end of the screw is inside the the large collar. Remove the nut and washer holding the flywheel on the crankshaft. Screw the puller collar fully into the flywheel. Now turn the screw handle inward to contact the end of the crankshaft. Tighten the handle down then strike the handle arm with a hammer for extra pressure on the screw. Next, strike the center of the screw with the hammer. Alternate strikes between the center screw and the screw handle. Do that until the flywheel pops free. Some pullers have flats for wrenches instead of a screw arm. The principle for removal is the same.

try checking your valves more than likely they are burnt. or u possibly need a valve job.

Sound like you have a stuck starter. try swatting the stater motor with a block of wood and a rubber mallet. if that doesn't cure it or dislodge it then I would start looking at a bad relay. Follow the battery positive secondary cable. ( usually a smaller gauge wire ) down to see where it attaches too. Find the main relay and I'd be wiling to bet the contacts are stuck or melted from continually trying to start it.

Hi and welcome to fixya,

Hi and welcome to fixya. The intake manifold should be taken as the last option. Basing from your description of the problem, the most probable case is poor firing. You will need to do a full check on timing, fuel mixture and spark.

Cutting out can be caused by poor fuel. In this case, there might be water on the carburetor reservoir. Drain the carbs. Until the muddy or rusty residue becomes clear. This procedure doesn't require you to open the carbs but if you want to be sure. You can do full carburetor cleaning meaning you clean the jets as well.

The rattling noise can be caused by timing. The timing chain maybe loose or there's a failure of one of cylinders to fire. Since you mentioned it runs fine again, im guessing there's a problem with the spark plug. Make sure you have good plugs. I recommend replacing them all at once to narrow down the problem. Even if the spark plug seem to be fine, the copper core could have been corroded. I recommend replacing it if its more than a year old and have been extensively used.

Make sure you have good fuel and air mixture. It usually is 2.5 to 3.5 turns out from a full close. but if you haven't made changes to it yet, let it be. This will save your plugs from wearing out too soon.

The leaky intake manifold can cause lose of power, and will definitely lean out the mixture. Physically check it to make sure there isn't any cracks or big holes that can let air in.

I hope this info helps.

FUEL LINE MIGHT BE CLOGED CARB NOT GETTING ENOUGH FUEL,CARB IS IN NEED OF SERVICE,JETS PROBABLY CLOGGED,CHECK FUEL FILTER SEE IF THERES ENOUGH GAS IN IT,ALSO CHECK GAS VALVE MAKE SURE ON/RESERVE AND CLOSE ARE NOT CLOGGED EITHER

Hi did you replace your plug cables, had that on my vfr400 . I replace the cables and problem solved.

I would take carnurator out and clean the jets. I believe I had the same problem, but everything works after a clean Carb
