I'm a PM guy I drifted away about a year after Brad started this fourm. I use to build YX motors and a few 124 crf bottoms. The big difference is I raced almost all the So Cal races. If we win our motors are torn down and checked. I'm thinking of running crf70 carb minus choke. We can have bars...
I need to see if they allow a oil cooler or not. That would keep it much cooler in the So Cal heat. That was one thing I was also thinking about was how often to change the oil. 10 hrs seems about right but what oil do you think would be best? I run Lucas in all my stuff plus I treat with Zmax.
Hi guys it been a very long time sense I have been on here. We'll my team and I will be racing a 24 hr endurance race at Willow. We will be racing in the Cup 50 class which is pretty much stock. I know most of the little stuff to gain 1/4 hp here and there to get a little gain. And some of you...
Hey, i never said i would run one but you all were talking about that 150 and this is a beefed up one of them. You think the crank would snap in this one to?

I cant see this being stronger then the 150 and they are breaking cranks.
