Clutch Grinding and knocking sounds

[Mickey112233]

The clutch on my 66cc has started to bind up when in motion and as revs increase,also has a grinding/knocking sound which rises and lowers as the engine rpms do the same. This engine has 68 miles total and is still in break in mode

I apoligize to all the members of the community as I am a total newbie to the correct use of not only forums but chats etc, I type with one finger and am just now self learning the ins and outs of internet use so please forgive me. My first build ended with a overheated engine, scored the piston ,cylinder walls and siezed up riding at 30mph did not fall over but did a far amount of "drifting". I rebuilt the top end, piston ,rings cylinder,cylinder head etc ran fine for 62 miles then developed clutch problems, I am in the process of a bottom end rebuild, I am saving up to purchase a Phantom 85 which I have heard is a more reliable engine vs these 80$ knock off engines, my lack of knowledge with the engines [2-strokes] contributed to the failures also, hopefully the learning curve is not too steep or expensive. I thank all of You and hope to be a helpful and fun member
