My grandson just completed riding today and his bike will no longer 'pull' in any gear when the clutch is disengaged. We checked the bike out and all fuel related issues are a non-factor. The issue remains, when we put the bike in gear it will not pull. Revs fine, no weird noises....just no pulling. Can actually sit in first gear, with clutch disengaged, and it will not move. When you give it gas it does pull somewhat, However, very little movement. Looking for possible causes...I am thinking he has fried the clutch friction plates and thus replacing the plates. What do you all think?

Welcome to the site !!

Yea it sounds like the clutch .... you need to take it apart and check the plates and springs , and see if they are within spec (most likely not if its slipping that bad) (do you have a Owners or Service Manual to check the specs , and a caliper to measure the plates and disks and springs ???) , not sure of your mechanical ability , but its a fairly straight forward job and if you can do basic maintenance on the bike , you should be able to service the clutch with minimal difficulty , providing you have the proper tools and manual for torque specs , etc. , also check the fluid , if it stinks , and is brown/silver looking then it is most likely toast and needs a good flushing of the case with oil till its clean , also after removing the plates and disks , you need to look at the clutch basket itself , if it has grooves like shown below , then it will need replaced as well

This is what a worn/junk clutch basket looks like (the notches make the clutch grab/jerky , it needs to be smooth)

Thank you JimDirt, truly appreciate the prompt response. I am decent with the mechanical skills and have the proper tools. You are confirming my initial thoughts. Truly thankful!!

No problem , glad to help ....

If you run into any issues , just ask ... a dumb question is always better than a dumb mistake ....
