Hi I currently have a raptor and 2 warriors, i love the raptor for the dunes with the engine mods i have. I beat banshees that are piped filtered jetted, and mild port jobs. But I feel the need for a 2 stroke and was thinking about a Zilla, what kinda mods should I put on it to beat some of the faster shee's, but the drag one's just the heavy port polish with compression and maybe strokers.

 

I am no expert but I would say get a different carb and pipe+silencer for a start and that will wake it up pretty good. You think your Raptor was awesome just wait till you get a Zilla! Its ballzy fast.

 

Ya I've seen a few piped Zillas over at dumont, they took piped raptors and any piped 4-strokes. I beat it by about 10 quad lengths though... I'm looking to make it rip. Are there alot of after market engine parts for these machines? reeds, pistons, rods, etc.

 

Unless your Raptor is REALLY modded, ( 686, 727, cams, porting, ect..)
That Zilla wasnt running right if you beat him by 10 quad lengths.

It would take some extensive mods to make a raptor run side by side with a piped Zilla running properly.

 

I've got a small bore 11:1 piston with stage 2 cam, new springs, pro flow intake, dyno jetkit 190;185, and big gun full exhaust i also wiegh 155-160 lbs, the Zilla was running properly. The other rider wieghed maybe 200 at the most, at least 180

 

Depending on what you spend. You still might not beat the highly mod'd banshees.
Don't get me wrong, there is nothing like the power of the big 500, and you'd be all smiles... Just don't believe that it's always the fastest thing out there.
It's all about cubic $$'s.

A good stage IV port job, mill the head to get around 180psi static compression (With the appropriate squish band adjustment), 41.5mm PWK carb, and a good pipe (Paul Turner or LRD) would make a very happy machine..
You'll always want to run high octane fuel with any head mod, as these pigs are prone to detonation. Coolant temp gage is a wise investment also... Overheating is a common killer of the 500's

One thing you might want to consider... a 2 stroke requires more maintainence than what you are used to.

Good luck
