starter

i have a 1984 zn 700 starter worked when cold after engine heats up starter would be slow. now starter does not work.solinoid is working fine i even tried a jumper wire to the starter with no luck. removed the starter and jumped the starter with a battery charger it works but is a little noisy so is my starter bad or do i have a differant problem ive only had the bike a few weeks s i dont know its history

Did you check the condition of your battery?

Can you turn the gear on the starter by hand? If it's anything like any starter on a car (I'm still a bit of a noob when it comes to motorbikes) it will spin freely with little noise.

Did you try jump starting the motorbike? If you can jump the motorbike, it's a battery or connection problem. Check you earth cable is in good nick and has a clean connection (and make sure that it's actually to the earth - the first thing I had to do on my bike is re-attach the earth, because the previous owner had bolted it to the battery box which is not earthed to the rest of the bike.).

checked battery first,i watched some videos on you tube on starters and i am pretty sure it is the starter. when i put power to the starter it just spun it did not jump off the floor like in the vids i watched. i am ordering a rebuild kit from RICKS ELECTRICS only 40.00 bucks
