Will, let me tell you the "Old school" way to fix this.(1) Remove all of the spark plugs. (2) Disconnect the fuel lines. (3) Pour light weight oil directly into the heads.(I know, sounds weird) (4) Crank Crank Crank Crank. Until the engine turns smoothly. If the valves were stuck, this should cure it! (5) Blow the oil out by the compression of the engine cranking. (6) Pour alcalhol into the cylindars to clean the oil out of the top of the pistons.(Starting fluid also works well) (7) Again, Blow it out using the compression of the engine. (8) Put everything back together and fire it up! NOTE!!!! Any time you know you are going to store anything with an internal combustion engine, treat the engine in the same way, by pouring oil into, and onto the pistons directly. This prevents seize ups, and helps to preserve oil seals. ^^

Check the cable is tight enough or if hydraulic that the clutch piston is not sticking

At the end of the wires!

Hi there are 4 m8 Allen head bolts use an m6 Allen key turn anti clock wise , beware there are two arrows these need to be put back facing up wards ,if you can't see the bolts there are silver buttons covering them there just pressed in a flat screwdriver will remove these try not to be to hard and scratch the sounding metal best of luck

Hi ok try the key switch follow the wires back u will find a 4 pin white connector disconnect it, then get two small pieces of wire and short them across each other ,so if u look at the wires there are two the same thickness 2.5 sqso these go together ,and the other two are 1.0 sq so these are shorted to each other one set is the control voltage for egnition the other is the starter circuit ,see how this goes ,if this is the problem the take the key switch out and clean it contact cleaner will do, don't forget to grease it after , also the fuse holder may be eroided so double check the out puts if a white coating then clean or and replace the fuses

I think the boots that is the rubber pipe going on to the engine from the carburettor ay have a hole or not be sitting quite right , on the side of the engine ,you can test this quite easy ,turn on the bike idle it as normal ,then spray carb cleaner on and around the boots it will make the bike race slightly this means there's a hole and air is been drawn in so mix ratio is wrong so loss of power ,do this to both boots hope this helps

Hi what are the problem with the bike ,eg what's it doing and not doing

if u only disconnected the cable it should just re-attach ! is the lever on the engine in correct position and have u backed off the adjustments ?

Any thing can be done, but. You would need a welder who knows their materials, types of metals. The biggest problem I can forsee is a distortin of the metal then you need a machine shop with a surface grinder to true it up again. I personally think it will be more trouble than it's worth

an absolute GUESS/Sudjeswtion, perhaps one of the diaphrams has a split/crack, thus y works with choke???

i dont kno your exact bike well but i have good genral knolage of motorcycle mechanics to kno what to fix if anything we need to know where it came from the only way to know that is to remove bits till u find what it snaped off of ok so i would remove the starter motor check all the teeth are in good condition and test on 12v power sorce ( battery ) to see it working corectly most starters have 1 wire going in positive from battery / relay and the negative power is from the frame/ engine earth id then check the cog it conects to and the flywheel looking for damages check the caseings for damages without more info i cant realy sugest much more a picture or description of the piece of metal would help is it steel or alloy ( is it magnetic? ) thatl narrow it down

replace the starter

Hi and welcome to the site,

Initially, is there a clicking sound? If yes, then check the starter relay. Temporarily jump the 2 big terminals. To locate the starter relay, follow the big cable from the battery's + terminal.

Good luck and thank you for asking.

What is it doing?

Your machine came from Yamaha with 20w-40 JASO MA motorcycle oil. Use any oil that has the JASO MA rating on the label. 10W-40 for cooler climate and 20W-50 for warmer climates. Do not use any oil that says "Energy Conserving" on the label, they can shorten the life of your wet clutch and transmission gears. Synthetic oils will help your engine run cooler and shift easier. An inexpensive full synthetic oil that is JASO MA rated and available every where is Shell Rotella T 15W-40 synthetic oil (about $23 a gallon).

sounds like a pilot jet problem. Pilot jet runs first 1/4 of throttle opening, main jet the other 3/4. Take out pilot jet (usually the smaller one next to the bigger main jet) and leave it in a cup of neat petrol overnight. By morning it should be ok.

sounds like the pilot jets are clogged,need to clean/rebuild carb,(carb kit).

There is possibly some dirt blocking the main jet supply or the float level has somehow dropped and the engine needs the extra suction to draw enough fuel in to keep running and it is supplementing this extra supply through the idle jets.

Hi there!
If bike is acting fine when in neutral, I would bet your problem is in your clutch cable, either it is broken of mis-adjusted. Please refer to the user manual and check the adjustment, because this should be easy to solve :)
Hope this helps!
