GOOD VIBRATIONS 1981
New Member
Hello all you gas heads out there. I am at my witts end with this idler pully problem. I have a 2 stroke 66cc china kit on a 1990 style huffy beach cruiser. Anyway the problem is when I go to start up the motor (rolling start) I get up to a good speed to pop the cluth and when I pop it the chain pulls the idler pulley into the spokes and trashes out the spokes then the motor fires up and the pulley bends back to it orignial spot on the frame and everything is cool. I have a ball bearing roller pulley mounted to the bottom bar frame next to the coaster brake arm. Also when I am at low idle speeds the tork from the motor wants to jerk the chain and it pulls the idler pulley right it the dang spokes again, but when i am at cruiseing speeds everything works perfect. I dont know what to do? I am pretty new to gas bikes and this is my first build and I dont have alot of money to buy new expensive parts. Any help will be greatly appreciated. Thanks you all.
