Noise from the Engine I own a TVS Apache RTR 180 (2011 model) and I am now looking for answers to the problems I have been facing. My motorcycle has clocked about 1.2 lakh kilometres. For the past few months I have been hearing a “clicking” noise from the engine. I have changed the timing chain and chain tensioner and also checked valve clearances but the noise not only persists, it becomes louder as the engine becomes hotter while riding. Moreover, the oil level dips inexplicably after about 1,500 to 1,700 kilometres.

Furthermore, I’m thinking of upgrading both the tyres to off-road sets. Will it be possible to fit the 100/90 R17 MRF METEOR tyre on the front wheel? The size of the original is 90/90 R17. Please advise me.

We are glad to learn that your TVS Apache RTR 180 has clocked 1.2 lakh km and is still running. As for the problem, there are two possibilities. The first one of these is that the valve stem seals have started coming off, which can result in the noise. The second is that the piston rings have been damaged. This can give rise to the noise you mention and also result in higher oil consumption. We would recommend that you get these two aspects checked by a qualified mechanic. As for the tyre, you may opt for a slightly wider tyre; however, please check the clearances to ensure that the tyre does not rub against the fork or the fender.

About the Instrument Console

I am a big fan of the “Technomail” section because I get to learn a lot about the technical aspect of a motorcycle. Recently, I bought a KTM 390 Duke. Now the company has launched the new 390 Duke. Although I am happy with my bike, I would like to change a few things on it; for instance, the instrument console. Is it possible to do so? Please advise me.

It is next to impossible to change the console as there are many intricacies involved in the procedure. All the electronics of the bike are connected to the ECU and changing something like the instrument console requires a lot of changes to the overall electronics of the bike to match the new console. Therefore, it is not advisable to do so.

How to Boost Acceleration?

I am a proud owner of a Royal Enfield Himalayan; however, I am not really impressed by the way the bike performs. I want to know how I may enhance its performance, basically the acceleration, without having to spend too much money. I do not want to modify the engine because it will mean spending a lot of money. Please suggest ways and means to achieve better acceleration at the minimum cost. Shiv Sharma, Nagpur The easiest, and also the most inexpensive, way is to upgrade to a rear sprocket with extra teeth on it. Putting a larger rear sprocket will give the bike better acceleration; however, it will also reduce its top speed. No major modification is required to carry out a sprocket change. Nevertheless, make sure to consult an expert and experienced mechanic before making the change, for he will be able to advise you about the exact number of teeth required on the rear sprocket to match your expectation.

Suggest a Suitable Upgrade

I am a huge fan of Bike India. I am currently using a Royal Enfield Classic 500. I want to upgrade to a bike that has greater power and torque than my present motorcycle and one that would not cost me more than Rs 6 to 6.5 lakh. What are the options available to me? Please advise me.

There are a couple of motorcycles that fit the bill. The first of them is the Kawasaki Versys 650, which is a powerful bike ideal for everyday riding as well as touring. You may also look at the Kawasaki Ninja 650, which is more suited to touring and is as powerful as the Versys 650. Both these bikes are within your budget. Yet another option that you may consider is the Harley-Davidson Street 750, which is a proper cruiser with more power and torque than the Royal Enfield Classic 500.
