Hi All,

I am new to XBHP, I have Yamaha Fazer 150 which is almost 4 years old. I intended to upgrade some of its components, I need your expertise on finding the right products.

First and foremost its time to change tyres

1 Tyres
Are stock tyres of fazer /fz16 are highly prone to punctures and do not provide good grip in wet conditions. But there aren't any other options available in 140/70 R17 tyres. So is it ok to go for 140/70 R17 tyres from other manufacturers what are the advantages and disadvantages of 140/70 over 140/60 tyres. Please suggest me a stable pair of Tyres. I occasionally go for touring and every day city commuting is around 25 kms on average. I stay in Bangalore so roads are not guaranteed of their condition.

2 Spark Plug and Air filter
When I have asked in the Panache Yamaha Show room, they said they will not install K&N air filter and Iridium spark plug as they are not standard. Are they are any issues by installing these. If they are no complaints or issues with installing them, Please let me know where can I get K&N air filter installed in Bangalore.
Shall I go with NGK or Bosch or iridium spark plugs and where can I get them in Bangalore.

3 Battery
One reason I wanted to upgrade battery is I wanted to install projectors as lamps. So Battery up-gradation is not necessary, but If there is an really awesome battery available for Fazer I would really like to change to.

4. Head Lamps
Another problem I am facing is night driving, I have calibrated my head lamps good enough but still I am not very comfortable driving at night. So please suggest me powerful and stable lamps set for Fazer 150. I am interested in installing projectors but afraid that it will drain the battery since my bike has no kick rod.

Are there any other upgrades necessary for a bike which is 4 years old . I am open for suggestions.

Thanks for your valuable time
