2016年7月9日 · A little dated of a thread, but my wife rides a CRF150R on trails in Pennsylvania. Her mods are: •Suspension rebuilt for trails •Crf450 front brake •GT216AA front tire •GPR steering stabilizer •G2 throttle tamer •R&D Flex Jet •Promoto billet Kickstand •Flywheel weight

2007年1月6日 · I tend to agree with you, I am considering putting in the 130 main again. The bike did start much easier with the WB setup, The anemic mid range may be able to be adjusted out, I left it at 1 & 1/2 turns out, I will adjust it out a quarter turn at a time to see if I get any gains.

2017年8月13日 · If you already ride a KX125, going to a CRF150R/RB is not an upgrade. It also depends what type of riding you do, meaning an MX race bike is maybe not the type of bike best suited for your usage. Edited August 13, 2017 by mlatour

2012年7月10日 · No doubt the front brake on the CRF150R is weak. I've heard this complaint more than once from customers. It is a fairly outdated system that was used on the CR80 back in the 90s and never updated (for some unknown reason). Here is an inexpensive alternative to the other stuff mentioned above, which by the way, will work well also.

2007年4月29日 · what about the new Megacycle 119-x3 cam compared to the crower stg 2? Frank from xr.100.com (engines only) seems to like this cam over the mega x1 and x2.

2020年5月6日 · The header pipe on the CRF150r is the same size at the muffler connection as the 250X so no modifications are needed there. The 250X muffler #001 is a bit larger, longer and heavier than the 150r muffler.

2007年4月23日 · What are the "stock" jetting specs on the 150R?? Wondering how essential the JD Jetting kit is?? I know for many bikes its essential, but how does the stock setup perform for most?? I plan on putting a heavier flywheel in and MRD pipe (when I buy the bike in a few weeks), and was wondering what j...

2022年11月28日 · 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!

2015年1月24日 · I bought a low hours 150R online, heard it running on the phone. The prev owner say's it's never been worked on since new, 25-30 hours total. I found the exhaust valve clearance at .005" & .006", the book say's .010". If the clearance was off, I would expect it to be more than spec, not less,...

2014年12月27日 · Hi, I recently bought a 07 crf150r for my daughter. Wasn't running well off idle. Cleaned carb, still was having same issues. After reading many posts i replaced the stock pilot jet size (40) with a 45. Nothing changed. replaced fuel mixture screw with an r&d flexible one, same issues with fu...
