2000 XR70 bogs down need help.

Recommended Posts

This is my son’s bike and we have had it for years with no problems. I am pretty sure it is stock, I am the third owner.

It idles but when I put it in gear and accelerate it feels like it is getting to much gas or air and bogs down. If I barely hold the throttle open it seems fine, it’s when I start to roll on the throttle it bogs.

I cleaned the carb with carb cleaner and took a wire and cleaned the jets. I cleaned and oiled the air filter, and also changed the oil. I adjusted the valves, intake at .002, and exhaust at .003. The green ground wire is bolted up with the air filter. I changed the spark plug also.

Any suggestions.:busted:

OK today a new day so I went and did some more research on the web. I recheck everything and the valves where way off. I think I was on valve overlap when I adjusted the valves. It runs better now it runs better but the idle is irratic. I think I will reclean my jets and use heat! or just get a new pilot and main jet.

Any suggestions?
