Almost certainly a 2 stroke but easy to confim, check to see if there are valves on the cylinder head, 2 strokes dont have any, check for an oil dipstick on the engine bottom casing again 2 strokes dont have an oil sump so no dipstick!

I just got a tomos 36cc or 50cc. Not sure what it is and don't know if it's a 2 or 4 stroke. How do I tell the difference?

Hi, Dale a 2 stroke has no camshaft or intake or exhaust valves and redlines around 12,000 RPM's a 4 stroke has valves, overhead camshaft or bottom end camshaft and pushrods and redlines around 6,000 RPM's The bike in your picture is a 2004/5 MC36 and is definitely a 2 stroke. The VIN# will tell you the year, model, and engine size. For more information about your question and valuable "FREE" downloads that you will need please click on the links below.

I am having shifting trouble on my 1995 tomos targa a35 motorcycle it takes a long time before it shifts and it shifts very hard when it dose

I am an actual Tomos mechanic, and all of you guys are a bunch of shadetree troglodyte mechanics who think that mopeds are the same thing as motorcycles because you have never actually worked on one.

A Tomos does not have "shift forks" "neutral" or "clutch cable" and the transmission is not built into the crankcase.

A tomos has a 2 speed auto that is a separate unit from the motor itself. it shifts between 1st and second via a centrifugal clutch, so if your having a hard time shifting then you either need new clutch springs and or shim/replace the clutch stones. should only take an hour if you know what you are doing.

How to bore the carb on a scooter tomos 49 cc 2008

You never bore any carb. To do so would destroy the carb. You have a Mikuni carb and nothing you can do to it is going to help add honest power to a 49cc engine. Sorry.

Tomos A35 start protocal

Okay, he it goes >
  • Start the bike with the lights off. The lights rob electricity from the starting system.
  • Kill switch off side stand up and gas valve on
  • Bike should be in neutral If the engine is cold, use the choke when starting. Twist the throttle about 1/8 of a turn while kicking the starter. Turn the choke off shortly after the engine starts and certainly before driving away.
  • Go to a Tomos dealer or any dealer, Yamaha, Honda, etc., and ask them to show you the general owner maintenance needed for your bike or any similar bike.
  • LEARN TO STOP. Sure, you can ride a bicycle and you have already ridden your Tomos, but you have not practiced for an accident. STOP! ! ! A car just pulled out in front of you! You do not have the time to think, " Now where are the brakes on this motorcycle? " Stopping needs to be a reflex. Go to an empty parking lot and practice emergency stops. Pretend a car or a child is suddenly in your path. STOP! Repeat this at faster and faster speeds for about one hour. Now when you need to stop you will do it automatically without even thinking... I just saved your life.
