Is this bike a yamaha rd 350 twin cylinder 2 stroke? if so, its air cooled and you should not be getting a ltr of water.. but it is common for them to have a "oily" fluid come out the exhaust because it is a 2 stroke. but not alot. it comes from the engine not burning all the oil gas mix. does the engine spit and sputter? make sure there is no water in the tank, make sure the air filter is clean and buy hotter spark plugs. also adjusting the fuel air mixture may help. hope this helps...

Im not sure I understand what your asking ? It's normal to have some black burnt oil coming out of your rs exhaust either way though.

Noticed an oily substance on the left front came out but cannot see where coming from -checked the oil and that is fine


More than likely it is leaking a few drops of engine oil either trough the valve cover gasket or from one of the valve cover bolts. more like the valve cover. Could be just loose. Check the bolts for torque.

Oil coming from exhaust


2 stroke poop! A certain amount of this is normal due to the oil/gas mixture you're burning. However, type of 2stroke oil used, amount used, and jetting of the bike can all affect the amount. If it's coming all the way out the back, it's time to repack the muffler. If this is the case, you'll probably notice your bike is a little louder and raspier than before. This also impacts performance negatively and, eventually, the inside of your muffler can start smouldering.

My 04 blaster smokes and idles poorly,dies pushing throttle


Hi I am vortash .. firstly 32 - to - 1 may be a tad high I would say ... it would be fine at the same as the ducati ratio 20-to -1 with a good quality oil , you should check that your sump is not filling with oil as this will cause performance problems with backpressure .. but maybe the best thing to do would be to replace the oil pump and run it as it was designed to do ?. I am sure you will get one off the net cheaply or from a local bike breakers .... Regards Vortash

Exhaust air stronger and warmer on side than the other.


check out any blockage in the fuel  pump as its getting proper pressure to get started.
