anyone take the side bleed and remove it and put a exit near the end of the pipe? Will this help on higher rpms? I do alot of parking lot racing. street tires
 
The stingers protrude into the expansion chamber. I would hate to ruin a pipe. The end bleeds do promote top end. If you are running the factory engine you will be limited on rpms. A race ported engine revs much higher.
 
ok. what top end kit do you recommend? Local hobby shop has a race ported kit for 30.5 comes with piston, cylinder,and gasket and new plug for $140
 
I'd go with the champ port. It's going to be a little cheaper from DDM when you use the 'HBF' discount code. Plus, you'll need to order those gaskets, anyway. May as well get them at the same time.
 
i know my lhs carries the champ ported esp and the head gaskets i would contact them and see witch headkit it is that way you wouldn't have to wait on the shiping price wise even with the cupon code you are only looking at around a 7$ savings in my opinion not having to wait a week for shiping is worth the 7$ lol

I would not save the $7. My problem is I keep shopping to try for the $100 and free shipping every time. LOL

A lot! The factory engine can hit 14,000. My OBR is pushing 20,000. Its not apples to apples though. The OBR is a 27.2cc which are known to rev to the moon.
