I'd like to draw on the experience and advice of the members. As a relatively new bike rider, having just bought my first bike (a used Suzuki 250 Djebel) last Dec., I've a few questions.... 1-Will the electrical system support upgrading the headlamp from the stock H4 55/60W halogen bulb to a 90/100W bulb? Is it possible to use an H4 Xenon bulb, or will additional heat be the factor? Also, are there standard 1157 'double bayonet' bulbs available that offer more than the 12V, meek 18/5W tail light bulb I currently have? 2-As the bike is used, though no probs yet in 14K km's, is it adviseable as a precaution to replace the existing throttle cables (2) and front brake cable? 3-I've a new o-ring chain...I've heard it's not adviseable to lube it with motor oil, or use solvents to clean the chain (?). The Putoline chain wax I have is expensive. Are there other suggestions for products that can be used with an o-ring chain? 4-For the sponge air cleaner, do I really need to coat it with a special sticky oil (if so what brands should I look for)...or will just plain 30W or 90W oil work as well? 5-I've read that upgrading the brake lines from stock to braided steel brake lines will significantly improve braking power. True? Worthwhile? 6-Are there high quality brake pads available that provide more heat resistance/less fade and better stopping power? brands?. 7- Sometimes the bike will be un-ridden for a month or more, so is it adviseable to add a fuel stabilizer to the gas. If so, are any fuel stabilizers available in Thailand (brands)? 8- Minor scratches on the my helmet's faceplate...is there a product locally available to remove them? While I know little about motorcycles, I'm somewhat competent as a mechanic on cars. I always upgraded brakes, lights, tires, and other components on cars I've owned and appreciate the safety aspects of such upgrades. Thanks in advance for your input!!
