I may try a gear change. I have to say its a little annoying. It would be nice to fix the problem. Its probably fine if your at the MX track and rippen all day. I think the bikes great for the woods. Just needs too be tuned.

The "problem" is it is a MX bike trying to be ridden in the woods , and by a novice rider , there is not much "fixing" you can do with that , it is the same exact issue people riding 450's encounter , a MX bike was not thought of during production to be anything else except a "race bike" , so though some of the attributes are things you like , the things you do not like are the very things that make it a good MX bike ......
I ride my 450R in the woods , and it made me think of 1 more item you can try ...... a heavier flywheel , or a flywheel weight , it will somewhat (it will add to gearing) help mellow the hit of the bike and make it more manageable , and it will help with stalling , I primarily ride my R on the track , but on occasion I do ride it in the tight woods , I also use it as a loner bike to some of my friends , those friends do not have a bike , and are also less experienced , what I do is run a 52 tooth rear sprocket (I use the stock 13 up front , and when I ride it , I run a 48 rear on the track , and 13/52 is the same gearing I use on my 450X **stock is 13/51**) , but the combo of gearing and flywheel weight , allows my less experienced friends the ability to ride the bike and for the most part , unless it is caused by lack of experience , they do fine with it and only stall occasionally or struggle in tougher spots , where without those changes , they would be miserable and struggle everywhere .........
The trick is , to buy a longer chain (I run a 120 link) and cut it down to the regular gearing links needed , but I buy a extra master link , and save the links I removed , then when I gear down (which is by using a larger sprocket) I add the links necessary ,then cut those to the length needed , then use the 2nd master link to join the 2 , what I now have is the ability to go from stock gearing , to lower gearing , using 1 chain , and all I am changing is the rear sprocket and adding the extra links ..... so it keeps the cost down , and gives a wide range of gearing combos , you can add 2 links if needed to add more chain length , by taking what you did not use with the extra link , and adding the remaining link/s , it will not weaken the chain or cause any issues (just make sure all the open ends of the link clips face backwards when that section of chain is at the top of the swingarm) ........
