Been mulling around the idea of either punching the 1300 out to as big as possible or just going with a turbo for it...Both would be a bunch of work but fun and do-able either way as I do have a good engine knowledge in both areas.. Has anyone done either of these to the Stryker yet that would have any info on it?! A good buddy of mine knows a bunch of ATV pro builders that have the ability to punch em out bigger but I'm wondering just HOW big one can go with the jugs on these.... Not to mention I wonder if my PowerPro AutoTuner would be able to handle the change either Turbo'd or Punched out....

I love the new power from the Cobra Intake, Swept Exhaust, PowerPro and 30tooth but am needing some more :)
And don't say go buy a Raider!!!

Any info helps!! ;-)

Nobody I know on this forum has done that yet. Closest would be Megabuddys NOS setup. Would most likely have to have a piston made as I don't think yami makes OS pistons and rings. Only Std jugs, piston, & rings. Would be a lot of Money spent to get 15 or so more horsepower, that you will outgrow in half a season and want more. Just my opinion.

Ceramic-composite cylinder sleeves are used and if I am correct cannot be bored or would take special stones to be honed.

Update- Just checked with Machining Supplier that I use for my business. These cylinders cannot be honed oversize. There are some Performance Specialists that use special boring process, but an Expensive coating process would have to be done afterwards to make cylinder usable. As always- nothing impossible as long as your pockets are deep enough.

What about just doing away with the ceramic sleeves and gaining more internal room through the use of Nickle plating instead after the boring like they do on ATV's?! The nickle would easily withstand the use as ATV's are much harder on as per the constant higher revs they deal with apposed to the random high r's with these bikes..
On the other hand.. I think the turbo project would fairly easy as well and smaller turbos for this type of project are fairly cheap to get ahold of and one issue would be in the construction of the turbo manifold which being a good welder I can make one of those myself along with the other exhaust needed.. The main issue would be tuning.. I am not sure if the Cobra AutoTuner would keep up and I may be forced to get a normal one and have it professionally tuned but thats minor in comparison...

decisions, decisions, decisions....

nicosil (spelling may be wrong) is whats used on most sleeves, you could find out the bore of the sleeve and what you could fit into the cases. then when you find that you can contact a place like lasleeve and have them make you a iron sleeve that will be put into place.. all that after you pull the motor apart and see how far away from the head studs the oem sleeves are placed to see what you could even fit into the jugs. then theres a problem getting pistions in the new over bore set up.

instead of trying for a cc size goal, consider pulling the heads and have them ported for a better flow profile. i havent pulled one of these motors apart but as all manufacturers do theres room for improvement for sure. i have never seen a huge gain in usable power from just going to a bigger bore alone, though portwork would make an even bigger impact for your money spent.

the force induction would be pretty cool on these, i think the problem that the v style motor is going to run into is that depending on the crank timing there may be a point where the boost pressure will back up because both cylinders are going to have the intakes closed at the same time. then theres the problem of getting a different set of injectors to feed you enough fuel to keep up with the need as your under boost. not to mention where your going to mount the turbo, piping routing ect..


the auto tuner i highly doubt would work fast enough to compensate for the boost if you go forced induction, n/a though it may if it has enough range in its tuning ability and is given enough time. much easier to get a power commander or something and have it tuned on the dyno..

If there is a will there is a way! :)
I'm still in prelim stages right now with contacting various people my buddy knows who do the nicol plating and what not on ATV's but I'm leaning towards Turbo instead...We will see..... I really love the sound the spinny things make and the pull they produce when spooled!!:rockon::biggrin1: hahaha
Ok so... The piping wont be an issue.. I can figure that out easy enough with my tig welding abilities.. Which also helps out for the oil return line.. Making a turbo flange wont be that difficult either as I Know a few good engineers with lathes and CNC's :thumb:
As far as the programmer.. I am with you guys, I doubt the AutoTuner will keep up so I will most likely have to ditch that and get a standard one and have it tuned.. No big deal.
As far as injectors go however... What lb are our stock ones?!

And this exhaust backup you speak of.. I will have to research that more so I can learn about it more.. Never really thought about that aspect of the build.. Any more info on that?! ;-)

I only plan on running between 8-10lbs of boost and I'm fairly sure this motor can take that...
Again, any and all info is greatly apprectiated!!

Thanks guys!!

Referring to the injector size.... I would like to think that the Injectors from the the Raider wouldn't be different externally.ie..actual size.. Therefore could be used instead along with the use of a inline FPR....
Does anyone have technical specs or knowledge of the comparison of the Raider vs Stryker injectors? Thread size and injector pressure numbers would be great...

:censored::boxing::playball:

I knew someone would go there! ;-)
Now what fun would that be?!! That's too easy and inside the box for me!! :-D
Unless....I could shoe-horn a Raider engine into the frame on the Stryker...........:smokin:
I looked seriously into getting a used Warrior engine 2 years ago. A lot of things to change around though.

You are looking in uncharted territory my friend. You will have to be the first to do these mods on a Stryker as far as posts in this Forum. I will help as much as I can.

For nikosil plating call or look up millennium plating, they handle a good bit of the industries plating. I have had them do a bunch of different cylinders over the years of atv racing.

I like the whirly things... Lol



I haven't found the cc size of the stock injectors, you may could build the system and start tuning it with the complete stock motor,then see where the injector duty cycle is at low boost.

From what I've read these motors already have forged pistons and a low compression ratio, may go good with boost if it's kept pretty low at first.

I love whirly things too!! ;-) And that thing looks BadASS!!
What are the specs on the turbo you are using? A/R's and such... I have found a couple small turbos that will work but options are good!!

I'm definitely leaning towards turbo w/ port and polished heads.. The head work is a no brainer that is for sure!

I suppose sticking with the stock injectors to start with would work too... Then if they start getting overworked and it starts starving for fuel find bigger injectors.. Would be nice to know what the stats are on the Raider and Stryker injectors ahead of time though..Wonder who would have some of these specs...

Why not cams, ported intake and high compression pistons, boost the octane level for starters.?

The intake will get ported at the same time heads are. I've thought about higher compression pistons as well but then I would do-away with going turbo..our 9.5:1 is about perfect for 8-13lbs of boost... The cams might be a possibility though.. I'll have to start looking for people to grind them as I do not know any....anyone?!
