If you want mad power than go with the crf. It's a beast.

I have not had it long enough to give a true statement. I have about 3 gallons on it so far and it's still going strong.

Shane Racer , have you had any problems with the carb ? I`ve heard that Picco and Picco based engines have carb problems like when the composite gets hot it warps and there is air leaks around the metal parts . Also what plugs have you been using ? I plan to get the CRF soon but can`t find anyone that sells Orion or Picco plugs and heard many other plugs don`t fit and leak .

I have not had that problem. I would recomend that you pull the slide out and take the sharp edges off the idle screw channel and the end of the slide just for added protection. Sometimes the carbs will stick just a little bit but after doing that they feel really smooth. I have been running a p4 in mine. I will be trying the Orion plug though.

Good motors, but all of factory motors are so similiar. Modded motors seem to make cusomizations that would be difficult to reproduce in a standard manufactuing process. I have found for the money, a lower end mill modded seems to get better performance than any manufacturer motor I have seen in the past.

You can`t compare a modded engine [lower end or higher end] to a non-modded engine . Like comparing apples to oranges .

Shane , are you still running Homer`s fuel ? Was thinking of making the change and after seeing the thread about it I`m going to . With the Orion engine , do I need to add or remove any shims to run 30% ?

I am running TQ fuel now and like it a lot. There is nothing wrong with tilted at all. I just had a good oportunity and took it. TQ runs very well and would recomend it to anyone. I've run it all summer and have had no flameouts or bearing issues.You don't need to add any shims. Just hang on because it's a beast. The bottom end is very controlable and when you grab a handfull it's very fast.
