Is it true?

[RamAir]

I read somewere that after the o3 moddel years so 04 and up Suzuki changed there cylinder head to a two dome for better fuel econamy? Is that really so or are there any better or faster GZ engines to be had? I just ran mine in the ground and will be looking for options.

All GZ engines are the same. Minor carb differences, possibly some emission stuff, but any GZ engine should bolt right in.

I read your I ran out of oil thread. This was a MAJOR whoopshit. :oops:

Check out eBay, they're probably your best bet if no one on site has one for sale.

Good luck.

:whistle:

[RamAir]

Oh no thats not what I was asking I know they all bolt up but was there a better cylinder head cuz if I am gonna get another engine I would rather it be newer or better or get better fuel eco.


And its mostly my stupitity that killed it not an Oops. I should know better! Grrrrr


Thanks for your input though. Keep comenting though I wanna know everything I can!

They've always been "Twin Dome Combustion Chamber" w/ twin exhaust ports.

Isn't this what you wanted to know??

O_o

[RamAir]

lol I suppose I should read more carefully next time! lol But I say that cuz this review I found!

read the last parigraph.

My Suzuki guru said that the reshaping of the Twin Dome head in 2004 was very minor, but did improve flow slightly and the mpg increased by 1 mpg, but was done mainly to lower emissions and keep EPA compliance.

He also said that the '04 and above US spec run leaner and a little hotter than previous models.

I would suggest to find the best available deal with the lowest mileage and call it a done deal.

WOW Man you know a lot. Who is this guru you know??? I wana be his friend. Thanks man I will take your edvise. I am gonna take it to a place in a day or to get a pros opinion cuz my grandpa says it might be the valves ticking, he says they may have bent cuz the motor ran so hot. So we will see.



I will keep you gus posted.

If the engine was smoking hot I would think the tranny gears were too. They would not be very happy spinning around without the oil to lube them. Let's hope for the best but I think you may have a really big paper weight on your hands.

I do use royal purpel in my motor and a k and n oil filter but I think the purpel really helped if it was some cheap oil the bike might have just stopped on me a wial back!

But..........a big but and just an opinion, the bike might have just quit sooner and possibly done less damage overall. A lesser oil might have alerted you sooner before thing really went South. With the tranny running dry, the cam chain running dry, no valve train lubing and the intense heat you are lucky it didn't just lock up at speed and spit you off into the weeds. You are probably looking at a replacement engine and tranny assembly. Not trying to poke at you or insult but I'll bet you will be checking oil on a more regular basis in the future.
