I agree with you , thanks to the guys who are actually techning these engine and makes proper call reguardless of whose sticker is on the engine . With that said at one time some of the engine builders who are utilizing these heads . So thats gonna cause a funny vote in my opinion . Anyone on bobs can buy a bare head for around $20 . Thats a very small expense in karting .First I'll say Thank You Don for your time and effort and being on the right side of this, and Thanks to the others for there time as well.
I know there's a Committee for rules and knowing some of the names on that list ( at least was at one time ) I can't believe this is going to go the way it sounds like it is, Perhaps the buck does not stop with the committee majority there more just a steering committee. If there is no place the rest of us can go to voice our opinions, I hope AKRA see's this thread.
Probably the way it’s gonna go. The new tool is going to check the total depth of the lower cut. It will force everyone to be on the same playing field
I was waiting on that question. Yes. In our research we found some of the 60 cuts so low as to get the valve as close to the floor as possible that the cut was “out of spec” with the new tool. Now that we implemented a .020 margin on the valve it’s gonna be difficult to sink the valves to close. Those that have not been cut really deep will be ok. Most of those heads had the seat sunk quite a bit below the floor which caused the problem. All of the TG 1 heads will be out of spec if hogging on the seatMy question will be, does the tool also make some heads that fit the current rule (30,45,60) also illegal?
That sheds a different light on things .I was waiting on that question. Yes.

Thank you and I agree about membership.Well don I agree with most that a thank you is in order from us to you ...I also am not probably as politically correct as you or most because I would not hesitate to call personally and let the one building these heads know the responsibilities of fixing his problem falls on him for cheating...he didn't just cheat his customers but everyone who raced against them .... I definitely understand there is a cost involved in this but I definitely don't want that cost to fall on someone who needs to buy an illegal part to compete ....but you have said that the flow difference did not show up on your check of this head so I definitely agree with you on a grace period to fix this then we DQ as we find the out of spec heads .... but I really do believe that we want members to join akra and I really feel like if that membership gave them a voice then we would be going in the direction along with the other benefits being a member gives you ...I have stressed to all that rolled through my tech last year how important it is for them to become a member if for no other reason just Incase they don't like my decision it gets them a second opinion.
Don don't mean to come off as a smart butt comment, but in my simple mind, my first thought is then WHY do we need a tool to deem it illegalI am going to shoot some pictures and post to my site for those of you who have the ability to look for yourself. I hope to do shots from the head off and ones by just pulling the carb and viewing things from there. One thing for sure if you pull the carb and notice after you remove the carb gasket to the “D” shape of the port and you notice that area “entrance “ has no defined edge as compared to known stock part it is illegal. This one particular builder is smoothing that are out. We warned him in the rule book last year but he hasn’t followed the rule.
To stop them from creating a better flow of fuel and air to the cylinder to create more horsepower. We need to get all heads on the same playing field now that we discovered what is going on.Don don't mean to come off as a smart butt comment, but in my simple mind, my first thought is then WHY do we need a tool to deem it illegal
