All You Need To Know About Motorcycle Spark Plugs

Writen by Maricon Williams

Motorcycle spark plugs have already caused several misfires. It can also tend to break into two when you try to remove them. These are instances when you are wasting money over low quality and non-durable spark plugs.

There has been a lot of puffing going out in the motorcycle market. Some are talking about horse power advantages. Nonetheless, be cautious of what you believe in, chances are they are just flowery words thus, misleading.

In order to avoid this, we have to bear in mind some pointers about this motorcycle parts.

First, always go with the motorcycle parts manufacturer’s recommendations. That way, you can never go wrong.

Second, if you have qualms over the parts, call the manufacturer to save you from further trouble. Do not experiment with parts, especially if you have little knowledge about them. They can go wrong in just a flick of the finger and can catch you off guard without any assistance and remedy.

For instance let us consider common motorcycle plug number: DPR9EA-9. This is a 12 mm thread 18 mm plug socket, P stands for projected electrode, R for resistor, heat range 9, E for 19mm thread reach, A for specials and 9 for .9mm plug gap. The next suffix letter is for thread reach. It can make you come unstock. If you put a plug with a too long thread reach then it puts a motivating impression in the top of the piston, if it is otherwise, it will not reach inside the combustion chamber. The next letter is again for construction features. There may appear another number after it. It refers to the plug gap which it is set at.

NGK plugs are good. The first letter prefix stands for the thread type and socket hexagon size. Their size ranges from 14mm thread to 8mm on the little 4 cylinder 250 imports. The second and third letter prefix refers to the construction feature.

With this kind of spark plugs it should be known that the higher the number the colder the plug. What’s the significance? Well, racing bike engines use cold plugs because they generate enormous heat. On the other hand, if fowling is one of your problems, use a hotter plug. Remember though that other motorcycle spark plugs have inverted heat range. Just consult the manual or your manufacturer to be sure that you are getting the right plugs.

If you are confused, you can always go back to the first rule - Follow your bike manufacturer’s recommendations. That rule saves!

In Motorcycle Racing or Canyon Burning Physics Matter

Writen by Lance Winslow

Any decent motorcycle racer or extreme hobbyist will tell you that the natural laws of physics do indeed matter. Whether you ride for fun, challenge or even race there is no doubt in your mind that the laws of gravity, acceleration, centripetal force and kinetic energy are very real.

In fact they can be your best friend or worst nightmare depending on how you chose to use them and there are plenty of broken bones and road rash scars to prove it out there. In Motorcycle racing you can feel yourself pulling from the turn due to centripetal force when you let off the throttle. So you get onto the brakes before coming into the turn and then feed the throttle thru it, while counter steering.

You can take a system of a combination of natural laws and change it around to fit your need for control; same with anything. Whether you are flying, sailing or skiing. Consider wind turbulence in an aircraft while flying straight and level. Your perfect system encounters an outside force, wind shear or other wake turbulence.

You were doing perfectly fine, aircraft trimmed up, nothing to do, but look outside, suddenly secondary forces. But provided every thing is correct no controls will put the aircraft into another stable system upon the disappearance of the secondary force. Or if it is strong it could turn you upside down into chaos if you are too close to the ground. You lose. Chaos wins.

There is no difference in motorcycle racing you set up for your turn correctly and prepare to adjust if anything changes or some squid loses the front end ahead of you sliding off the track. Either you adapt or end up eating pavement. Hey you decide, but do not ever believe you are above the natural laws of physics out there. Consider this in 2006.
