As the clutch is let in and revs slowly increased (as normal) to take of in 1st gear, the clutch isn't gradual. It is sudden, grabby and noisy. It will stall if abnormally high revs aren't applied. Impossible to take off on hills. Once in a while it works normal. The problem doesn't seem to appear temperature sensitive.
The clutch is NEW! It has been out since replacement and is fine. Gearing isn't too low.
Fully Synthetic oil is used and changed regularly.

Re: Grabby clutch in 1st.
I'll bet you replaced the "fiber" plates only in which case you need to either take the steel plated out and have them sand blasted, or preferably "glass beaded", you have a hot spot on one of the plates which is causing the clutch to be "grabby" also not sure if you replaced the clutch springs but if you did and they are after market they may be to high of spring pressure. Did you install a stock clutch or a after market one? Many times the after market hi-performance clutches are made with aluminum plates and then they add the fiber and the clutch will chatter because the engine HP to to substantial for the aluminum to handle. I highly recommend using the stock Yamaha clutch plates and springs. They are of the highest quality and are the best to use. Please let me know what type of plates you are running and I'll work from there with you. Also if you cannot get the plates blasted you can take them out and rough them up on your garage floor. Your want to use even pressure and move in a circular motion to scratch them up. Make sure you clean them afterward in mineral spirits. You can buy that at any paint store real cheap. Good Luck, RSelvy

Is your clutch good put it in 1st gear hold the brake on and try to move rev it a little let the clutch out and see if it revs up or wants to stall do not burn it up just see if it slips in 1st it just may need a clutch adjustment.
Find a long straight road that climbs fairly steeply get into top gear at about 40 MPH then try to slowly accelerate. If the clutch is slipping you will find that the revs increase but the speed does not. It is not a good idea to rev to the max in each gear it can damage the engine and gearbox. Have you checked the clutch cable and the adjusters also is the clutch release mechanism (push rod I think in your bike) working correctly. A poorly adjusted or damaged, un-lubed cable, with no free play at the lever will not help a clutch to operate properly. I would also have the clutch checked as it could be the friction plates are worn and/or the spring tension is incorrect. (Wrongly adjusted or weak springs will also not help the situation)
Sounds like you have a slipping clutch. You can check your owners manual for the proper clutch lever free play. A quick check would be to see where you are starting to engage the clutch or friction zone. With the bike warmed up and running, shift into 1st gear and then start to slowly releash the clutch lever. If the clutch does not start to engage until the lever is 80% released, then you can try adjusting the clutch lever free play. You can do this simply by sliding the rubber cover from the clutch lever. If the cable end is showing a lot of threads then you can loosen the larger lock nut, a serrated looking wheel with a slot in it, and give the cable end a few turns in. Lock in the lock nut and start the bike and see if the friction zone is catching earlier. Try adjusting to get it to catch within the middle of the travel. Once you feel you have the clutch adjusted, give it a road test to see if the engine will not rev higher without a corresponding increase in motorcycle speed. The owners manual will give you a precise range where the clutch lever free play should fall, usually measured from the end of the clutch lever. If the clutch seems to be adjusted properly, then a worn out clutch could be the problem.
hi, if when you start your bike you press the gear lever down to go to 1st from neutral and then pull it back up to go to 2nd,3rd,4th and 5th then the only way to get back into first gear is to press the gear lever down 4 times to get it back into 1st gear their is no quicker way to do this you have to work your way back down the gears.
if your coming to a stop quick then just pull the clutch in and keep pushing the lever down until it dont push down any further it will only go down 1 gear at a time so you will need to push it down 4 times but you dont need to count you can just keep pressing it down the gears until it dont go down any more then you know this is first, you need to keep the clutch in when doing this.
how ever if your slowing down is more gradual then what you can do is go from 5th down to 4th then let engine slow the bike down then when the revs drop down change down to 3rd and so on until you get ot 1st gear.
if your coming to a stop quick say at lights or junction then if the bike is in 5th gear then you can change down the gears once the bike has stopped just hold the clutch in when you stop and keep tapping the gear lever down until you feel that its not going down any more gears this way you know its in 1st without having to cound down the gears, their id no quicker way of going down the gears to get to 1st.
i hope i have read your question right and gave you the answer you was looking for if i got the question wrong then please explain then i can assist you further ok
well this is something that is as you said " not normal" i would guess that clutch is smoked. after it warms up do a 3rd gear roll on at about 45 mph. if you drop the hammer and the motor revs and you don't go anywhere stop the ride and R&R your clutch
something else to make sure of is that you clutch fuild is good and has no air in the line
pull left leaver (clutch) foot down one on left prody thing (gear shifter) keep clutch in bit on throttle so it revs up then let clutch out slowly until it hits bitting point rev abit more and let clutch full out it will accellerate once done let off revs pull clutch gear shifter up fully release clutch and hit revs and when ur on the road it will be easily done and letting clutch out and revving will become simunatiosly
to slip clutch then rev high and let clutch out smooth and excact to bitting point and keep it there
u sound smart n thanks for goin oldschool-1st buy a manual-thats how the pros work--in bike yrs its in its 50's-parts wear out-try ajustin cable n then do clutch itself-that does not help-rebuild is probable
This sounds like a broken tooth on the main axle. This would account for the lump in every gear and a power loss due to the axle being bent also. I would change the axle, support bearings, and the gear the axle engages. Check the output shaft for bending also.
This could be bad bearings on the shafts but is is highly unlikely if the gearbox oil has been kept at proper levels. In any event, the gearbox will need to be opened up for inspection.
