new clutch?? need help

[MIA_BLASTY_305]

Hey so i just bought a freshly rebuilt motor for my blaster and put it in so i took it out to ride after breaking it in and when i would go more then like half throttle the bike would not go any faster and giving it more gas would just rev the engine like if it was in neutral or with the clutch in. Then i rode it the next day and could not get it past 20mph no matter what gear.

Clutch is slipping, id bet the pressure plate isnt put on correctly, the is a dot on the plate that lines up to a doton the boss, if not in time the ppressure plate is held out away from clutch plates very slightly. If its in time was the pressure plate adjusted properly, as so that the lever arrow points to arrow on case,

Is there some slack in the clutch cable?

 

[MIA_BLASTY_305]

Thanks for the info i havent opened it up yet but when i do ill look for that.

 

[MIA_BLASTY_305]

Nope not at all. I spent like 30 mins playing around ajusting the clutch cable to no success still slips

 

[98blaster]

Dont ride it anymore, your just gonna glaze the plates if it hasn't already, then youll be replacing it again

 

[MIA_BLASTY_305]

Yeah im not riding anymore because its super boring going slow lol. But im just gonna buy a new clutch anyways. God knows if the idiot who rebuilt this motor replaced the clutch or not

 

[Blaaster]

Do you know what oil was put in the transmission.

There is supposed to be some slack in the cable to stop it riding!

I put some lucas 80w 90 i had laying around lol

 

[Blaaster]

That could be the cause of the problem, I doubt that it is designed for wet clutch application.

It is very important that the transmission oil in a wet clutch box contains no friction modifiers!

"I just want to ride" strikes again.
I see a new clutch in your future

 

[98blaster]

80w90 is pretty thick oil, an gear oil usually has friction modifiers in it. Flush the trans case, replace the clutch, make sure its assembled and adjusted properly, then fill it with bel ray gear saver 80, or type f tranny fluid

 

[Blaaster]

Or use the oil recommended by Yamaha, 10W30 engine oil with no friction modifiers.

 

[speedyslyder]

only my opinion...get rid of that heavy 80w oil it is going to kill your clutch,put the 10w30 in get it at a dealer,or the type f tranny oil that you can find at autoparts stores.

it hold 650ml no more no less it is written on side of bottle,its almost like 3/4 of a quart,but important that you measure it
