The answer is "sort of". Yes you can get dedicated "wets" which are race tyres for wet tracks. They are soft and heavily grooved but are not a practical solution for daily use. To be honest I think this is really a matter of learning the limitations of your tyres in different conditions and riding to the conditions. There isn't a magic tyre that will make ...

It sounds like the root cause of your woes is a battery that is not getting properly charged at lower speeds. Assuming this is a 14 V charging system, the battery voltage should be close to 14 V while the bike is running. If it isn't, the battery will deplete and affect components that rely on it like the fuel injectors and coils, which would go quite some ...

Unscrew the spark plug, and touch the edge of the plug where the thread is to the metal engine block somewhere near where the plug is threaded into the engine. Make sure you don't have gas fumes everywhere. Hold on to the plug via the insulated wire, so you don't get shocked. Make sure to keep the plug threads touching the engine, and the center electrode ...

The EXUP servo is responsible for closing a valve in your exhaust to create a known amount of backpressure in the exhaust system to allow the engine to work in the way it was designed. If you have swapped your exhaust then chances are you have already eliminated the EXUP servo. You can create one, a quick google search reveals you only need a capacitor or ...

According to this User Manual on Page 53 (section 6-3) a Valve Clearance check should be carried out every 26,600 miles (42,000km). It also highlights any other maintenance that should be done and at what intervals. I think checking is relatively simple (assuming you are handy with a toolkit. I found a site that gives this method of checking your valve ...

Short answer: Yes. Long answer: Maybe? As long as it is a 12v motorcycle starter relay you should be fine. The problem is whether or not it will fit your bike physically (that is whether the size of the solenoid will fit into the compartment designated in your motorcycle, and whether you have bullet, spade etc etc). I have used a few of the cheap Chinese ...

The most likely culprit is the piston rings. One way to check before you replace them is to compression test the cylinder, then put a few drops of motor oil into the spark plug hole, and retest. If the compression goes up, it's because the oil is making a better seal on the rings. Replacing the rings on a single-cylinder motorcycle is fairly easy, search ...

The closest thing I would consider to be a bible for maintenance and repairs would be a Haynes or clymer manual. http://www.amazon.com/Yamaha-XT600-83-89-Clymer-Manuals/dp/0892875461 There is a difference between maintenance and repairs. Proactive vs reactive. Learning how to do basic maintenance will teach you a lot about the bike and what tools are ...

Perhaps a forward facing intake would be good for the engine but the disturbance it would create in the air infront of the bike would be quite bad for handling, straight line stability and completely negate the effect of the fairing. On a basic commuter bike, the problems with a forward facing inlet would be compounded by bikes that are ridden in all ...

First of all by "most production motorcycles" I am assuming commuter level motorcycles used in South and South East Asia its not true that all production motorcycles have intakes facing backwards, its more or less a ergonomics based design decision , some motorcycles have intakes facing 90 degrees to the side. Some have them facing towards the back as you ...

The phenomenon is called as hitting "False Neutral" while shifting. Basically when the clutch is not able to engage the selected gear properly the drive shaft stays in the mode of stasis . i.e simulating the effect of the bike being in neutral. The only difference between a regular neutral and this one is that you don't see the neutral light on the dash. ...

Your Carburettor might be clogged. Clean it along with the air filter and you should be good to go. Also check if your "choke" chord is not faulty since it will tend to send a rich mixture to the engine which will stall it at low RPM and you get that "Missing" feeling but more importantly your fuel efficiency is affected.

I've had this on a few bikes and it can happen for a few reasons. If it it's only happened a couple of times i wouldn't be too worried. I've had a 'false neutral' when changing gears and instead of engaging the next gear the gears don't quite engage and you end up between them. Older bikes with higher mileage might be more prone to this. To avoid it I've ...

Also I want to add my 2 cents. When I look at Yamah FZ8 I see that it is water cooled... so I think that the purpose of the fan is to push air on the cooler as it should have a bigger surface than the engine itself. When you turn on the ignition the fan pushes air on the cooler but the water pump is not running as the engine does not run. So I would think ...

Stopping a naturally aspirated engine will cool it down, regardless of the fan running and etc. The idea behind "turbo timers" on turbocharged cars is not at all engine cooling related, rather it is to allow the delicate and extremely hot turbocharger components to cool down via keeping the oil feed circulating through it for additional 15-30 seconds or a ...

If the height of the new piston above the rod connection centerline is greater than for the old piston, that will increase the compression ratio quickly. For the assumption made by Zaid on the stroke, a height change of 3.2 mm will produce that new compression. If that is the case (taller piston) you would also need to wonder about valve clearance.

There is no way that a 1 mm increase in bore diameter will change compression ratio that drastically unless the stroke is changed as well. My rough calculations indicate that the change in bore will result in a new compression ratio of 8.66:1ยน. Even though you're not after power per se, the higher CR should translate to more torque. A rebored piston will ...

The clutch actuator that pushes the clutch pushrod for the the throwout bearing and the pressure plate from the left side of the engine to the right side of the engine through the primary shaft has a ball and ramp setup. By removing the inner actuator for the ball and ramp that has a worm screw actuator you can add a groove by pushing the actuator into the ...

Mine is Cast iron 1993 model Enfield Standard, I have one query, What I mean to say is even i have the same Tappet sound, but if we are not tigeting the tappet fully it will effect the engine, so if the sound is coming means it doesnt mean like your engine have any issue, as I knows, you should service from a good mechanics, and ask him how to effect this ...

I know that Fiat, with the old FIRE engines (that's Fully Robotised Integrated Engines) used to run them up to 14,000 RPM for 20 minutes and if they passed that trial, they'd put them in a car.

You say that several diodes died. Is there still one or two good diodes remaining? If so, connect one of the good diodes in series with a light bulb drawing about 1 Amp or more to your bike battery. Measure the voltage drop across the diode. This will tell you whether you have standard silicon diodes or Schottky diodes. You can then choose ...
