I haven't rebuilt one of these in a long time, but, I'm currently having an issue with my timing chair going around the front sprocket and screwing back in, I'm not sure why there's not enough slack for it, any tricks or reasons for this?

@@WaldensWorld thanks, but the timing chain on the bike itself was a tad short, I had to legit use a flathead and pry it to get it back on, the holes and everything wouldn't lineup, I then removed it after and just out the whole top end in my other engine and it all fits fine, it's the timing chain itself was the issue

Wasup man I got a 125 rfz starts up good rides good but once it’s fully warmed up after riding it around for 30 min or so it’s starts to smoke from exhaust and I’ve noticed that there’s a air hissing sound coming from the hose that connects to the air box and crank case any idea on what that might be about

I’ve got one of these and when I pull the throttle back there’s a rattling sound, the previous owner says it’s the muffler, but it sounds like it’s coming from the engine, anyone know what that could be?

I’d check the valves see if they have to much slack in the adjuster first

Is it burning oil ? Is vent from engine hooked to air box ? Bad rings time for rebuild or if you have vent to box u may have carb leaking into engine n blowing oil into air box then into carb ! Idle I’d check the gaskets around the intake for cracks or leaks ! Be my first guess n thanks for watching
