Re: Ninja 300 (engine) rattling noise

A 4 lac bike with engine trouble is not good. To add to it not many owners ride Ninja hard. Hope it is just a one of case.

Re: Ninja 300 (engine) rattling noise

It can happen with any engine irrespective of how much the bike cost. Its not related to cost of the bike, its more to do with various other factors including what was the condition of the engine. I have seen a R1 with a engine seizure due to oil starvation just like this one. The guy was not a show boat or street maniac. He is a very experienced motorcyclist who treats his bike well. So does that make it a bad bike? No, its just that the odds were not in its favour. It drew the short straw. No bike maker claims a six sigma accuracy. There are always going to be such cases somewhere or the other.

Re: 2013 kawasaki ninja 300 - rush is addictive

Hi guys ! Thanks for the input !
The run in (or break in) was done correctly - did not exceed 4k rpm for initial 800 and did not exceed 6k rpm - until 1600 kms - I also don't red line the engine ... Always stay below 12,500 rpm , for ninja 300 redline starts at 13000 rpm and ends (max) at 15000 rpm. Previous service was at 20,000 kms. Now the odo is reading 25,000 kms. I have given it for service right on time , that is every 5000 kms and maintained it very well.

I dont exactly know which is the cheapest brand slip on available for Kawasaki Ninja 300 , but those i have seen the cheapest is the Leo Vince GP CORSA which comes in two different makes, one in simple alloy and other in carbon fibre which costs 17.5k and 19.5k respectively here in Mumbai

Hey guys I wanted your views on how useful crash bobbins are. Here's a pic:

Also how good are they if you fall on rough roads (where the ground is not perfectly straight)?

^nd

Once we took a look at the rear sprocket, the scope of work was dramatically increased. Instead of just installing the rear sprocket we decided to replace and renew the entire drive train. To get maximum benefit we decided to a new chain and front sprocket.

Vikram of Motozone sourced a Vortex 14 teeth Stainless Steel front sprocket. For the chain we decided to use Rolon X ring chain.

We started to work by removing the rear wheel. The current rear sprocket is made out of mild steel. It weighs more than 500 gms whereas the Renthal sprocket is about 100 gms. This was change was going to reduce another 400 gms of un-sprung weight from the machine.

Changing the chain and sprockets requires a lot of patience, as the swing arm needs to be removed in order to facilitate the removal and installation of the chain.

The first impressions after the change are dramatic. Now the torque is well spread out across the range and the bike is once again extremely smooth and streetable.

The mild steel sprocket.

Renthal sprocket being installed on the wheel. A perfect fit.

Front stock sprocket. Note the speedo sensor that picks its signal from the front sprocket nut.

Rolon X ring chain.

Vortex Stainless Steel front sprocket 14 teeth. Note the gunk that gets collected below the front sprocket with regular lubing.

The gunk being cleaned thoroughly before final assembly.

Front sprocket and chain ready for final assembly.

Rear Sprocket and chain ready for final assembly.

A very special thanks to Vikram and Vijay of Motozone, Pune for the efforts taken by them to source the parts.

Is the rear sprocket made of aluminum? I read somewhere that the light-weight aluminum sprockets are usually reserved for racing because they don't last very long compared to the steel one.

Wouldn't it be because of the difference in usage when it comes to racing and street riding, how much should a bike run in normal conditions to reach the wear and tear factor involved in a race condition.

Re: 2013 kawasaki ninja 300 - rush is addictive

^^^ most people tend to think that steel is stronger than aluminium. They would be right in thinking so if what we are talking about is steel vs. pure aluminium. However, what we are talking about over here is actually aluminium alloy. Specifically 7075 grade of alloy tempered to what is known as T6 grade of tempering.

7075 grade aluminium alloy consists of aluminium, copper, zinc and magnesium. When tempered to T6 grade it has a tensile strength of approximately 550 MPa which compares very well with mild steel which generally has a tensile strength of 400 to 450 MPa.

Therefore, it's a false impression that people have that aluminium sprockets will last less than a mild steel one.

Sprockets and basically any parts used in racing may not last as long as in the streets not because of the material used but because of the kind of usage and stress it will be put into. You won't be riding as hard on the streets as on a racetrack.
