If this is an automatic 4-wheeler, the shifting fork will bend when shifting from fwd to rev. or vis-versa. because your not completely stopped when you change directions. (kids do this to mine so many times I am tired of changing the darn thing) The part costs appx $50. Looking at the old part you can't tell it's bent.... If it's a manual tranny then your linkage is worn and needs adjusted.

The altenator is usually 3 phase. It is unlikely that 2 phases have gone down, more likely the diode pack has failed. Check the rectifier/regulator before taking the engine to bits. It may save some time and money on spares you don't need!

.035" works well for most bikes etc.

See the www.ngksparkplugs.com site and enter your model info and the info is there.

Hope this helps.

how do you fixs pull ropes for yamaha kodak

Hi,

Firstly, if you are not a mechanical person you should never buy a vehicle that does not run.
However, here are some basic tests.
1. Connect a good battery.
2. Remove the spark plug.
3. Turn the motor using the starter motor or kick starter.
4. check for spark by inserting a new plug into the plug cap. (make sure the plug is grounded).

If the motor turns freely and there is spark, chances are good that the motor will run. This does not mean that the motor is in a good condition. Only with the motor running will you be able to know for sure.

You will now have to source a carb and fit it to the 4 wheeler.
Fitting the carb is not too difficult. Check that the intake manifold is not perished or torn, and remember to use the airfilter.

Enjoy the ride !
