Enough.... You should have dipstick to tell you how much oil should be used. This dipstick is meant to be checked when fully screwed out and with the bike on the center stand if available. If no dipstick, you should find a small glass window somewhere on the side of the crankcase. Compare the oil level there to the marks on the crankcase. If you're still confused the FSM should have more accurate fluid requirements for different situations/procedures.
Hi, Anonymous you may need a top end overhaul for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix or parts inquiry. If necessary transport your vehicle to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your issue. For more information about your issue please visit the website below. Good luck and have a nice day. 4 stroke motor Parts 50cc 70cc 90cc 100cc 110cc 125cc horizontal motor Documents matching bajaj pulsar 150 Scribd
if its a 2 stroke then you need fuel spark and air to get the bike to start have you got compression? check it by removing the spark plug and put your finger over the hole air try and start the bike your finger should be pulled into the hole if not then a piston ring is either cracked or broken
open the air box and check the filter then clean the carb thats all you need for a 2 stroke
if its a 4 stroke then again check the air filter and compression remember that a 4 stroke doesnt have the oil with the fuel it goes in a separate chamber
Go easy on twisting the throttle. Every time you twist, a shot of raw gas goes into the carb. The bike will flood easily. Put in a new spark plug, clean the air filter and drain the carb float bowl. Then get a can of starting spray. Spray into the air filter and then try to start it. The gas valve is turned on isn't it?
Please rate my answer. Thanks.
The single coil ignition system works on a twin cyclinder 4 stroke motor by sparking every revolution. In other words, whilst one cyclinder is on a power stroke, the pother has just started an intake stroke, and so both spark plugs can fire together every revolution using a single coil.
Happy to answer any questions you may have about this. Thanks for using FixYa
get a can of starter fluid and spray a short burst into the air intake...it should fire up...if it won't stay running or idle your carb is clogged from storage i presume...right? usually storage for more than 3 mos will clog a carb if you did not winterize it...Good luck to you friend...Tim
Who said the swap would work? If it was the dealers shop mechanic then it may work. Anyone else and I would be doubtfull.
The old Yamaha 125 / 175 could swap. The key is the stroke length. You are changing the bore, no big deal. BUT if the stroke is different the swap will not work.
Check with the dealers parts department. Look at the engine specs of the 49cc and the 70cc. If the stroke is the same, then it MAY work. A few unknowns are present. Ignoring the unknowns, did you use new cylinder base and head gaskets? New carb and manifold gaskets? Where is the 70cc carb and manifold? You have 42% more gas/air mix needed but a carb designed for 42% less than now needed. If nothing else, the engine may be starving for fuel. Granted the carb may have the 70cc capacity, but the only way to tell is by compairing the part numbers at the dealers.
One last thought. If the engine is a two stroke, how good are the crank seals? You are increasing the bottom end pressure by the swap. How much pressure is getting past the seals? Lower than needed pressure = no go.
put your hand over the carberatoer to choke it while your dad kicks it and after about 3-4 kicks in the middle of him kicking et go and it should build up enouphg pressure to start it up.ive used this method many times on my 200cc yamaha
