turn off the key, hold the choke button and keep on kicking the crank handle for a few times but dont turn on the accellarator, After that turn on the key and release the choke button and slowly turn on the accellarator after every kick

What model - year - etc>??

Selecter forks could be damaged, gear shift shaft bent, return spring faulty, clutch dragging maybe! Try rocking it backwards and forwards engine off and see if you can find that gear! Good Luck - The Yeti

Yes , you should be fine since you will only be stretching up one size. Most tubes will fit a multiple of sizes. Just work carefully so you do not puncture the tube while installing it.

Here is a diagram of your transmission.

65PSI is way to low. It probably won’t run at 88PSI either. Put a small drop of engine oil (20w50 or similar) into the cylinder and do the compression test again. If there is a big improvement in compression it means the piston rings are worn and you will have to do a top-end overhaul. As a very rough guide you need 150PSI for a 4 stroke engine and about 120PSI for a 2 stroke engine.

low speed carb settings need ajusment also look at choke-cleanin may be in order

If you can remove the old one,just bring it to any bike shop and they should have it.There are probably at most 4 different kinds over the last 20 years.Also,one brand isn't any better than the other.There may be slight differences,but they are not worth $2-3 apiece,I don't care what the parts guy says.It's his job to make money.It's my job to give quality advice based on facts and research,whether I get paid or not.Gold or titanium tips or whatever they are trying to sell these days makes no difference.A good metal to metal electrical contact is what matters.Gold is actually one of the softest metals too and I sure don't use them.They are much more likely to scratch just from putting on and taking off the plug wire. Good luck and ride on!Greg

Sounds like a head gasket leak or cracked head

You need immediate repair. It can be caused by blown gasket or cracked coolant line

Sorry guys but its probably not!!! left hand theads the clutch nut is peened down on the threads dont beleive me look you eill see little lines or punch marks on the nut their is a special tool you can buy or you can make one like i did to hold the clutch hub still.You were on the right track with the impact wrench if that dont work you dont have a big enough air supply for the wrench good old elbow grease should get it i did it by hand after i had the tool. PS- you must punch the nut in a few places once reinstalled. I learned the hard way by breaking it first

no its not right,, check the limit screw first to see if its backed off to much allowing the throttle to drop below the idle point, if this isn't the problem,, the carb itself need to be adjusted

Hi
As long as they are both 12 volts the battery doesn't care. Put the charger on the lowest setting and remove the cell covers from the battery. Make sure acid is over the plates. If not add water. Just trickle charge or you will burn it up!

have you tryed a new spark plug?

take it out and weld it ...its simple & easy

DOES IT HAVE SPARK?

dirty air filter bike not getting enough air to run and there for too rich a mixture!

You mean cylinder jug? You don't hone the heads, but they do have special tools for polishing the valve seats. Usually they just spin the valves with a drill motor and some grinding compound to get them to seat tight, water tight. The jugs are honed out with a big brush that looks like something a chimney sweep would use. It has polishing stones on the ends of the bristles. but, they do that after the jugs are bored, they have honing stones for crosshatching the bores, kinda smooths them out. If you don't bore out the cylinders, use one of them. Check it out.

Add a bigger carb, tune it well and play around with the transmission, that is with rear and front sproket.

Hello the ignition switch bolts from the bottom you will need and 1/4 inch drive 8mm or 10mm socket a universal,short extension,1/4 inch drive ratchet.
you will have to turn the forks to the most suitable position to attach the socket to remove the switch.
Hopes this helps you.
