84cr125 said:br10 semms a little weak for trail riding, thers alot more low end and alot more oil could foul out easy. Try br9eg or br8es for a cheap solution.
84cr125 said:when u do trail riding you are in the lower rpm range and prone to foul plugs. You need a hotter plug to burn off the extra oil. a 9eg might do it. the heat range on plugs got 10eg cool up to like 7es very hot.
take a look at this reading guide, then maybe it will make sense. http://www.ngkntk.com.br/site_ingles/direct/p4.html

This makes a bit more sense;
DO NOT CHASE A JETTING PROBLEM BY CHANGING SPARKPLUG HEAT RANGES!!!
84cr125 said:Trail riding is not wrong jetting...... if he was to rejet for trail riding and then say drive down the road back home in 5th or 6th he will risk a seizure. If he keeps his current jetting which is good for high speeds but switch the plugh to a higher heat range he will be able to burn the extra oil at the low rpm, range.

KX'er said:I trail ride, my jetting is pretty close to perfect for both trails and mx. There is a reason why there are different jets for different throttle positions. I use the stock heat range plug. I don't change for one environment or the other. I have absolutely no problems with fouling.
Jesus, where are all these people coming from? I've seen quite a few posts that have just absolutely stupid suggestions. If you don't know, don't answer. A few years ago this was a good board.
