hey guys just picked up a 05 crf 50 for dirt cheap. i just have a couple questions.
1. what is the engine oil capacity for an oil change?
2. i put on a tb 20mm carb kit on it and the bike idles great and the runs good in the upper RPM, but bogs down to almost stalling on the bottom end unless i slowly roll on the throttle. the kit came with a couple other jets. so not sure if re jetting will help this. also the core out of the exhaust is missing.could that be the cause for the low end power bog?
