I've looked up all of the C5 manuals and the C6 manuals on line, and cannot find a picture of the same head button I have.
Could someone please enlighten me? I've spent hours trying to find the correct one.
Thank you,

Steve, captian is right...the non beveled button will work on your silver case the button you have is unique to the silver case Rody signatured. good luck finding it specially now that Sigma trading is gone. it gave that engine a broader range of power from top to bottom. I have both black and silver..My silver case Rody will smoke the black case anytime. try the new button and add 1mm shim from what you have as it is. and see what happens. good luck

Hey guys, does anyone here have an RB Matrix, or know anything about it? I haven't heard much about it at all, and no one really runs RB where I race. Do you think it's a good engine? What about performance, how does it stack up against other high-end racing engines?

Can anyone give me some instructions or point me in right direction on how to remove the piston and sleeve. I need to get my p/s pinched and I know there is a certain way the rb needs to be taken apart as to not break the piston skirt.
Thanks,
Chad

Raise the piston to the top of the cylinder before you remove the backing plate. Then after removing the backing plate, lower the piston back down. There are a few different methods for removing the sleeve. You can try rotating the piston and this may raise the sleeve enough to remove it. If it doesn't I lower the piston down and then put a zip tie in through the exhaust. Then I raise the piston up and that will normally raise the sleeve out of the case enough for you to remove it. Remove the sleeve, then take the conrod off the crankpin.

Still on the head shims, how do i change them according to the altitude. If i race at sea level what should be a good start point in head shims and also if i go race in a place which is 1000Meters (3280.83 feet)? Another question how should i change the head shims according to the Temperature/Humidity ?
Thanks in advance.
I almost forgot, i run 30%. (RB MATRIX ENGINE)

Steven, thanks for the info. The zip tie trick worked like a charm. Is there any trick to re-installing the p/s? I'm sending this one off to be pinched.
Anyone know where to get a p/s and conrod for a ws7? I want to freshen up my spare. Actually I have 3 conrods that fit good on one of my cranks. I have 2 that say 2 on the top and 03 on the bottom and the other one says 9 on the top and nothing on the bottom. What one is better?

Has anyone tried the JP 2031-H pipe on their Rody C6 in the past? I ran one at the Midwest Series race on mine and it seemed to work very well. I didn't have a 2018 to compare it to though.
I've also played around with the 2013 (non-conical header) and didn't care for it too much.
The 2031 (with short header) seemed to have very good bottom end and great fuel mileage. I do think I gave up a little on top end so I was just curious if anyone had experience with that combo. Thanks
