Dirt Bikes Engines

Bicycle higher ground, making strange noises engines?

one of its two-stroke bike BTW The older you just get the engine 3 began last week, been riding for some time, now sometimes when we ride and give more than 50% throttle the engine sounds like its bogging down and then theres a sort of rattling noise from the muffler, leaving the accelerator stops, but if I go back more than 50% happen again any ideas about the causes? and a remedy to fix it? Its from 1976 and theres not much information about him one of its Can-Am 125cc two-stroke oil injection

Without more information about the bike, will be whistling in the wind to try to answer. What year / make / model is the bike? How long did it sit without running before get it started? Your best bet is to find an aftermarket shop as a Clymer manual for your type of bike and begin to solve problems.
