[Four Stroke Tech]

I have 09 teryx with msd, muzzy,dalton od plate, going to do clutch work possibly vforce john stage 3 build have been thinking about egine kit, don't know much about any of them, have talked to Todd at Hunter Works about a standard bore with cams. Could any body tell me what the 840 kits include, who makes them, what kind of hp they produce,what if any extras i would need to go with them besides what I already have, what is the rough cost of them, and reliability and longevity of the engine. thanks

My std bore kit comes with the pistons,stage 2 cams and valve springs for $850 retail,$765 members cost.The 840 is just as reliable with 100% no problems just like the std bore kit. The 840 comes with pistons,stage 3 cams,bigger head gaskets and valve springs for $920 retail,$820 your cost. The 840 has to be bored and re-nicasiled and that cost $500 more if you want us to do it. The std bore we did for Crowdog on here gained about 90% more hp to the rear wheels and the 840 was 135% on the one done for this site as their projuct. Both of these were 08 carb models done on Weller's dyno. Dasa Racing has built a 840 09' and is about to do the std bore also to have all the maping ready to go for both. They also have all the injectors and air box needs for you too.As far as longevity,no one know because the Teryx has only been out for two years. To date I have sold 420 of these kits,some have been on the Brute Force since 05' with no problems,and there where kits sold for the Teryx even before they came out. So what I am saying is there are Teryx's out there from day one with my 840's in them and are still going strong.

Wells what odd is the Std bore kit from Fundy is approx. $1550 while Mickey's 840 kit comes to approx. the same, maybe even a little less. So what gives there?

$1328 for a 840 with the cylinders done.I have seen guys that paid that price for a std bore,then tried to sell them at the very low price of $1000. They couldn't understand why no one would take it for that. Might have something to do with my retail price still $150 less then that,let alone members pricing. I will admit prices are going up here soon.
