First trip out on the trail my son's new YZ85, I took a small coke bottle of premix in my fanny pack and wanted to ride until he run completely out of gas. He made it 28 miles with it running very rich. He stays on it pretty hard too. Don't know if you can compare the two, but I really believe he will be ok with a few miles left.
Sounds like you guys are going to the Little Brown Jug?
We will be there also. I had called yesterday and got some info on the kids race. In the past, my son has been very disappointed in the length of his races. Seems like they would race for about 10 minutes and it was over, so I believe he is gonna love this one. About half way through mine, I may be wishing I was on the 18 mile loop. :scream:
My son is 12 and riding a YZ85 and I ride a DRZ250. Maybe we'll see ya'll there. See us, be sure to say hello. Also, I drive a Kia Sportage. Shouldn't be too hard to spot. Not many folks try that. :)
