gonna go with 11:1 wiseco piston.... any opinions and possible downfalls to boring stock sleeveto 101...wanna keep it thick or going with an la sleeve 102 sleeve? it's basically a matter of $$$ vs relaibility
LOL I want to do the same but stay with stock bore. Wife says not right now. So I will keep reading up. Good luck. I would stick with small bore but that is just for the sake of maybe having to bore it later and or wanting to stroke it.
i'm a small dude....60hp will be more than enough for me....no strokers here
You got me wondering if 60 is possible without stroking. and without spray.
You talking at motor or tires?
at the tires....and it doesn't take much to get to 60hp
this is a fairly large displacement motor as is.....letting it breathe and complimenting it with a little cam here...a little bore and hi-comp piston there.....alittle porting and bigger valves sprinkled in.....bake it 4 a bit....60 hp
I have one in my 350, and it made a big differance for the better, but 660 im sure is completey differant..
yeah....a 660 stock makes more power than a 350 with the piston.....
Stay Stock Bore easier on the Connecting rod unless you plan on doing a rod swap to
hehe i just went 11:1 101mm wiseco :grin_nod: ooo and i went with a wise hot rod :) just ask hammo about the connecting rods :(
gonna go 101 bore should be ok on a stock rod....
yeah 101 only adds a few thousand pounds of centrifical force at the end of the rod...
BTW Just how much power do you think you gain in that 1mm bore?
not really any....it was just to give the cylinder a fresh round untapered and honed finish...

The 1mm isn't going to make much of a difference in cooling or reliability. But a 101mm sleeve can be bored again, a 102mm sleeve has to be replaced if it gets too marred up or out of round. The aftermarket 102mm sleeve isn't any thicker than the OEM sleeve bored to the same size so there's nothing to be gained there.

A piston alone won't get Alex to 60hp but I'm guessing he has more planned. Small bores can break 60hp on pump gas, 105+ big bores can break 70 with stock stroke on race gas.
thatll be a sweet improvement :thumbs:
see md knows what's up....
Where can I get a 11:1 wiseco for a 660?
they're about $130 on ebay.....or rocky mtn. etc.

Are you looking for new or used?
New, I'd contact Steve @ TQS or Kenneth @ KBM.
Used, it may be worth while shooting MadDog a pm. :thumbs:
i like those kenz pistons but they're more than double the price of anything else.....so wiseco seems like the way to go.....for sure stay away from the je 12:1 for the 660
any updates?
I was also wondering at 11:1 what octain are having to run? 91?

Never had a problem on 91-93, even ran 89 a few times on 80+ degree days in the sand without any pre-detonation or pinging. I would suggest premium on a stock or stage 1 hotcam, might get away with mid-grade if you've got a stage 2 or more aggressive camshaft and a bit of porting.
Well was gonna go with mild P&P and was told to skip stage 2 and go with the 3.... So many opinions... LOL
Just wanted to make sure I can run on pump gas.
i'm in the same boat. Cept it is my bills holding me up right now! And I'm looking to go 11:1 stroked, stage 2 or 3 cam, new springs and valves. to compliment my full ct exhaust. I'm not sure how big of a stroke I"m going yet. I have a worked up 700 to chase down. :) I can hang with the Suzuki lt450R's I'm not sure if they were stock or worked any. I didn't get a chance to really ask any info on them. But in roughly a 300' I was either dead even, little ahead, or a little behind every race. unless either one of us got a really good jump on the start. i'm wanting that 700. I have to look up his profile on raptorforum to see what he has.
Here is what he has i'm not sure if he crossed over to this forum or not.
mine dyno'd 38hp and 34 lb/torque. I have a JE12:5 piston,barker dual exhasut,T-rex port with +1 valves,X-4 cam,+2tb,dynatek,power commander and gytr intake w/o lid.However it is tuned perfect and runs strong. it pulled 93mph with stock gearing on the dyno against the break and overheated the dyno to where they had to abort the tune until it cooled off.mine was tuned by reading the CO2 instead of O2. they tuned it to a 3.5 CO2 reading at every 200rpm's up to 8000.So i think i can brag and say i have the fastest 38hp raptor on the planet
38 hp after all those mods? Stock 660 rated at 36.5. I know hp is arguable when compared with different dynos. hmm?
gonna say mine hit 43hp at the tires with just pro-flow and jetted with barkers. All other on the motor is stock. that is at 1000asl.

41 with HMF slip-on K&N jet and lid drilled. HMM?
That's a low to mid 60hp 700R, you'll want 65hp+ or a much better chassis setup to beat it.
are the rings close enough for a drop in? or do most need to be ground?
that 700 should be in the 60's and yes i know for a FACT it is FAST and yes it hit 93 on the dyno for a minute or two and it acutally ruined the tires. i was there, its my moms bf's 700...
ceanern sorry to say but i think youll have to dump ALOT of cash if you want to catch devans bike. hes also runnin vp race gas now so theres a bit more power too, and i think he put the 15t on not sure about that tho.

depends on the age and condition of the cylinder. mine was an 03 purchased new, put in a 100mm wiseco piston in the winter of 04. ran that piston until 2007 when the cylinder started to oval, did a couple of re-rings to it in that lifespan (honed of course) but mostly to keep it reliable as we didn't see any compression issues.
measurement of the cylinder would be the place to start with that question, IMO it's worth taking the time to measure and order second, or make sure you can return it if you need a larger size.
I have maybe 20 hours on bike....
getting ready to do its first "needed" oil change.
Thinking that the bore should be ok. That is why I wanna do the piston now while stock bore is still kinda fresh...
Sounds like you'd be in good shape then for a drop in (new piston/rings/wristpin/hone)
use a ball hone on it to scuff the surface?
trying to get everything ordered here and in by sept 12.
