now there is few steps you have to follow if you missed one of the step the bike
won't start
hi guys welcome back to Mini Bikes Store video blog in today's video I'm gonna
show you step-by-step how to properly start dirt bike DS67 from Nitro Motors
this is one of the smallest dirt bikes with 49 cc two-stroke engine with
standard carburetor so in the previous video I did show you how to properly
assemble the bike and how to prepare this bike for the first start and today
I will give you full instruction how to step by step start the bike the dirt
bike comes with a 49 cc two-stroke engine so you need to mix the petrol with oil
in the ratio 25 to 1 with the bike you will get the mixing bottle so I show you
now how to prepare the fuel in the mixing bottle first you have to prepare
the fuel you have to mix the two-stroke oil for motorbikes with unleaded petrol
with the bike you will receive the mixing bottle when you look close to the
mixing bottle on one side it will say 1:40 and the other side it will say 1:25
so you have to use the side with the signs for mixing 1 to 25
so when you look close you have 2 lines the bottom line and the top line you have to fill
the petrol up to the bottom line and then fill the oil up to the top line
so I have the bottle filled with petrol up to the bottom line and now just add
oil up to the top line
next close the bottle and shake it well
so now the fuel is ready you can put that fuel into the tank
so when you have the fuel ready you can put the fuel into the tank don't put the whole bottle of it
put a proxe half of the bottle just in case of any leaks
now there is few steps you have to follow if you missed one of the step the bike won't start so
make sure you follow all the steps first put the key into ignition ignition is
located just here so put the key into it and turn it to right that's ON now
on the left-hand side on the handlebars we have the kill switch this is a kill
switch so make sure to place the kill switch well in position like this
here is OFF switch so you can press it and make sure it's not stuck inside here is working properly
this white plastic here is a petrol tap so turn it to ON
like this up and down this is an ON position from the box the bike will come
move the petrol tap in on position so you don't have to touch it but just make
sure the petrol tap is in this position up and down this is ON position
next to the petrol tap it's a choke lever so pull the choke lever all the way up and leave it up
so now the bike is ready for its first start we have added the
properly mixed fuel we have the petrol tab open we have the choke in up position
we have the key ON we have the kill switch placed on and we have checked the
off switch and now we can start the bike
to start the bike put your right knee on the seat to hold the bike your left hand
on the throttle and pull it, this is a easy pull start you don't have to pull
aggressive you just pull gently to the bike start you may need to twist at the
same time the throttle little bit while you pulling
when you hear that the bike start you need to pull the choke all the way back down
so now pull the choke lever all the way back down like this and in this position the choke has to be
when you use the bike
so now you can start the bike again
we have now started the bike with the choke in the down position and now we
need to adjust the engine idle speed the screw to adjust engines idle speed
is just on the left-hand side on the carburettor it's hard to see it
so you need to put the screwdriver under the gear on the bottom
and then when you turn it in to the left it will lower the idle speed and when you turn it to the
right it will higher the idle speed the idle speed of the engine has to be as
low as possible so turn it to left and start it again
so we have adjusted the idle speed of the engine it's very hard to show you on this bike but I will put
some video short video of how to adjust the engine from the other bikes
on the left hand side on the carburetor you will see screw with the spring on it
that's where you lower the engine idle speed
so now we can start the engine again
the idle speed of the engine is a in little bit too high so I will adjust it again
so I have adjusted the idle speed again
so it's very important that you properly adjust the engine idle speed after you start the bike for the first
time otherwise you may damage your clutch if the idle speed of the engine
is to high the clutch will be in the half-open position and will burn out very quick
next you should properly brake in the engine you can start the
bike and leave it running for a few minutes 15 minutes and then for the next
three to four tanks you should go very easy on the bike make sure the engine
properly breaks in so this is the procedure how you start the 49cc
