bb pipe?

[hartwill]

You guys think I need a big bore pipe for a 335 motor? Or what do you guys recommend? I was running a sparks mx pipe but I just switched to a Paul Turner type 6 to see the difference. But It seems to run a little warm plug looks good so I'm not lean. 55 pilot, dgg needle mid clip, 185 main, 39 air striker. Will a big bore pipe help it run cooler? Also what should an infrared thermometer read on the head? Oh it has an aggressive low to mid port job..

A big bore pipe with larger diameter stinger will help the engine run cooler but it will make less peak HP. See if bigmatt will chime in about his sparks mx big bore pipe. I think it would work good on a 330-350cc engine set up for low-mid rpm. I have the same pipe but no BB engine or silencer...

I run a ESR TRX5 with my 330 5mil and it works great. You should be fine on a 335cc build without the bb stinger.
