Just out of interest.

These guys supply SCCA. Those JB roller rockers are what I want.

but Chris, they are the same price as full YT rollers..
and they are only roller tip..

Yella Terra? Nah.

These are neat and closer to the factory design which I like. They are also bushed with an oil grove in the bush, so I wouldn't expect them to wear the rocker shaft out nearly as quick as the stock ones.

I just think they're a great piece of engineering. If I literally had to choose, it would be these by a mile.

the YT ones would be stonger and stiffer, I red up on them and theres more to them then it might seem

You own a set of Yella Terra's of course you'll say that.

If you are talking about the rocker arm being stiffer and stronger, I'm yet to see even a stock rocker arm fail, so where is the benefit it in that? I reckon it's a bit of peace of mind, no?

These are simple little items that fit the stock shaft that are designed with smart lubrication features. Their smaller size to yella rockers probably mean they're a little lighter too, further alleviating pressure on the associated components.

How much do the push rods cost for the Yella Terra setup? And where can you source them?

Quite true.

Pushrods werent to expensive from 'rocket'. buy the looks of those ones you will also need ball ended pushrods, and how are they adjusted??

Rocket Industries?

The push rods themselves are adjustable.

Though I do remember there being a design that worked with stock push-rods.

yella terra rockers are heavy, and they dont come in as high a ratio as the JB ones.

Yella Terra's are only cheap now because the market is pretty sparse and they can't sell them off. That chap on ebay has sold 3 in the last couple of years (two this year).

JB Rollers are selling like hot-cakes because they're an outstanding product which is reflected in the market, which also explains the price, holding strong and well worth the money.

Saying they're just as costly as YT Rollers isn't quite true, as the cheap YT ones are the 'NLA sale' items. YT don't make them no more. Weren't hey worth over a AU$1000 when first manufactured?

Do your self a favour and buy JB. Put the Yella Terra's on the shelf behing your bar so when your mates come round you can tell them about how rare they are........and why they aren't made anymore.
