Hi, I'm new to this website. I have posted two questions, but received no reply. Maybe you can help. I have a two year old doodlebug with a bad centrifugal clucth. I have removed the clutch, which came apart not intact. I have a stock Lifan 2.8 with an 11th clutch with a 35 inch chain. Multiple questions. Am I too heavy to ride this at 210lbs? My son, Nick is 10, and it is his bike. It's pretty fun , but I am wondering if it was not only my inattentiveness with the lubrication requirements for the clutch as well as my heavy ass trying it out while trying to recapture my youth. Lastly, I have seen clutch replacement on EBay for about 35.00 plus shipping. Is this something I could do better buying locally? I live north of Kalamazoo, MI. and wondered if I should try a parts store or a bike/ snowmobile shop. Any advice you might have would be appreciated. Thanks for your time. Regards, Jayman
