Thanks Aaron. Got it back together. Tore all the grass outta my backyard. It's a bottom end wheel standing monster.

Hello Tom,
I actually have a Shark9 that I am breaking in for Ofir. It looks to be a very nice engine.

Headbutton cutout?
 

could someone post a pic of the C6 us head button with the relief/cutout on the exhaust side? Thanks

can anyone tell me a cross reference for a ws7III rod? i am having a hard time finding one.

If anyone is interested, $165 plus freight, this engine has a new TKO front bearing and new conrod, the engine had almost a couple gallons ran through it and then the new bearing and conrod was installed. After the bearing and conrod installed ran once in a borrowed truggy to make sure it ran good and put away for a spare. The clutch is not included.

Hello Bigred,
The rods are all the same for the "S" and "C" series.
It is a beautiful thing!!

I may be wrong but I remeber seeing on RB's parts list that just about all thier motors but the C6(squarer stroke?) use the same part # con rod. As far as another brands fitting I have no clue. I wish someone could find a replacement rod for GRP.

The RB conrods .21 are all the same, including the C6, the new 9 series are the same conrod also, the killer 9 is not the same conrod.

ok thanks alot for the info guys.

Can I get some opinions on putting a killer 9 engine in my mbx6t w/ an rb 2045 192 exhaust set up. Seems to have a good price for what it is.
Thanks

It will be awesome! My Killer 9 in my 8ight T 2.0 with 2045/192 pulls just as hard as my C6 BBT7 with a little more top end. I get about 10 mins on a tank and after 2 gallons I still have a ton of pinch. I encourage my fellow racers to try my truck on race days during practice just so they can feel the smooth power of this engine. It will be my next back up engine for sure!

I run it with 25% Byrons Pro and OD97T, temps are so cool I don't even check anymore. Engine holds a very consistent tune as well.

Hobby 9 carb settings
 

Hi ive got a RB H9 with a couple gallons on it. I recently switched fuel and now it seems my needles are off, like almost a full turn. I just need base needle settings to get me back to factory setting. Thanks.

Base settings are 3.5 turns out on the high-end and 5 turns on the low end needle. Don't forget to reset your idle screw before you start tuning.

What fuel did you switch to and from?

The first 2 gallons were sidewinder, im now using nitrotane and im deffinetly switching back to sidewinder or odonnell once im done with this gallon. It took a full turn on both needles just to get it the ballpark.

metal pinch after 2 gallons?.....or COMPRESSION?
