Looks to me that I need to find a new set of GX valve springs or some replacement springs.

I've looked for some links to merchandise, donations but find nothing.

If someone could some up the issue with a few sentences, it would be great.

I use this website for 60% of my research and find it very useful and a tool that I cannot be without. I'm proud to be a member and would like to help where I can.

Matty, is it possible to list what parts is in this A12

A14 Sub
A12 GX Head
Dual SU Carbs
A12 Flywheel modified to 5.8kg

Limited to 7000rpm
Seems to get valve bounce at 7100rpm.

And this sucks, a lot, hoping to fix it thru this post

Remember my father saying this thing should do more than that. Could it be worn out valve springs or am I so far off, I need to sit in the corner and punished for being stupid.

I've done so many searches on this site, but still can't find the answers.
So let me ask a few relevant questions.

What is A series Motors able to rev in standard, lightly modified, race modified trim?

What is good modifications that can be done to increase maximum revs?
Balancing, light weight rotational parts etc, please add to this.

Please add your Axx series and the amount the bugger revs, some detail on modifications. This could be quite interesting.

I would like to know if A12 GX springs have a life time, I'm suspecting mine.

But I still have no prove.

Seriously considering importing a set from pitroad. You AUS ppl are so fortunate, Yen country is so close, you can jump in the ocean on a Sunday morning and be at home for supper with your new set of springs.

I even know of a 1200 sedan with a A15 with dual sides standing in Hartswater, all stripped out for gymkhana racing. The owner is sparkyza1.

Nice to see another Cape Town man here, if it was me looking for a datto race car it will be a ute: Reason, to be different from the rest.

Otherwise the sedan, I just love the looks of it.

Have a chat to Rezlo, he races one up country with a lot of success.

No, this is the first website I have this problems with.

Personally I do not have a idea of what could be the cause.

Would creating a new userid and testing with it be worth it?

danielblues I captured a screen shot at home last night, hope this will help in some sort of way.
