Crf150f vs crf125fb - What Motorcycle Should I Buy? - ThumperTalk
网页2020年10月4日 — If you can find a CRF150F, IMO it's preferable to a CRF125FB. - it has a 2" higher seat height so more 'growing room'. - the 150F has a 5-speed gearbox versus the 4-speed of the 125FB. - the 125FB has a very low-to-mid powerband then falls flat on it's face at higher rpms. - both have the same size wheels /tires but the 150F has more …
CRF 150 r hard to start - CRF150R/RB - ThumperTalk
网页2019年5月13日 — Our starting sequence. 1st turn fuel on, fill bowl, turn off. Two quick twists of throttle, set choke, two slow kicks, re-twist throttle twice hold closed, two hard kicks and usually starts. Turn on fuel and away you go. Hot start in procedure if motor warm. Our 150R floods easily, and Lilly the 12 year old rider does not have much of a 'leg ...

How competitive is the CRF150R vs. SX85? - ThumperTalk
网页2017年7月3日 — As with any class, the fastest rider will win on whatever they're riding. The 150 vs 85 is less of an advantage as 125 vs 250F. The 150 has the typical low to mid range advantage but the KTM will walk away on mid to top. I have to assume your child already knows how to keep a 2 stroke on the pipe therefore diminishing the 4 strokes advantage.

Electric start is possible on CRF150R & CRF150RB!
网页2022年11月28日 — Eric heim. Well, after a couple years of promoting and bugging them, they pulled it off! The pre-order is live for electric start on a CRF150R or CRF150RB!!! This bike is the greatest mid-sized bike (in my opinion) and this will totally change how smaller adult riders and kid riders can now use this bike for EVERYTHING!
2020 CRF 150RB idle issues - CRF150R/RB - ThumperTalk
网页2021年5月18日 — What I would try to do, warm up ur bike, adjust ur idle, to low RPM. And pull choke out, see if there is any difference, rpm should go up. If no changes, then choke might be a problem, need to be clean. Also make sure ur air screw adjust properly, usually u can find how many turns in manual.
2007 CRF 150 R No spark won't start - CRF150R/RB - ThumperTalk
网页2008年8月14日 — mcguyver. If the plug is good the MOST probable cause of no spark is a bad ground at the coil. Remove the tank, look for a short wire from the coil to a round brass connector attached to one of the coil mounting bolts. Remove the bolt, clean the connector and reassemble. If that dosn't work look for moisture in the flywheel conver area.
