I'm convinced that for what most people want to do a standard bore kit from Fundy is the way to go, they are making 15 to 20 hp more than most 840 kits.

840 Kits are held back by carbs, intakes, heads and exhaust kinda corking them up. Yes you get a nice gain but more can be had, less trouble and less money. Sure you can uncork it but heck then you got about $4000 tied up in the mod and you then will only barely outrun the standard bore kit.

Another issue with 840 kits are warped cylinders because they are so thin plus the heat.

When you can make a reliable 90 crank HP and 65 HP at wheels you are doing something.

We are going to install a Fundy standard bore kit in a 08 Teryx and get a good set up and then do a 09 and map it on the forth coming MSD ignition/fuel controller for those want to just plug and play when the MSD comes out.

I would have loved to do our own kit but Ray at Fundy is hard to beat so no need in beating a dead horse. Our part will be the set up on fuel and ignition, exhaust etc so you get a complete set up with no worry about compatibility issues and it just plain hauls butt!!

standerd bore

Glad to see todd Iv got mine running good now. 160 dj and 165 dj 4 tpi valves and a k&n inside the airbox. I can play with the 4 tpi valve but normaly run with 3 open. 65mph with a GPS with stock 26" tires at 9200 RPM then hits the rev limiter. I had some over heating problems running it hard, but installed a pwr rad and and the new updated fan. It still ran a little hot so I tried some evens NPG+ and it really works and will not boil. I found it to run 15 deg cooler and now its all I can do to get the temp up to 210F running as hard as i can. I can spank a 1000 prowler by 7 car lenths before 65mph and it comes out of the hole like shotgun 4 cars by 30 mph. I took some tip weight off my dalton primary arms because my mud tires are 28" mudlits and needed more rpm It would even pull harder with more tip weight.I have 4 months of testing different combos so let me know what you end up with.

OK Todd you are going to need to back up a bit.To start with how many 840's have you seen run vs a std bore?. How many cylinders have you seen warp. The answer is zero. I have sold over 300 840's and not one problem with any of them,fact! Yes there is alot more power to be had with porting ,carbs ect.I DON'T KNOW WHAT YOUR PROBLEM IS WITH ME BUT YOU NEED TO GET OVER IT. I have never did anything to you but we have already had that talk. You have not even run a 840 against a std bore. You are going by Ray's word on this and I can tell you fist hand Ray and his HP numbers a hyped up to sell parts. You should really watch what you repeat because it will backfire on you, just like it has with Fundy.I can't even believe you even say stuff like this with out first hand knowledge.Yes the std bores run good but these things take torque to move them,even more so then a quad. HP numbers don't tell the whole story. I have seen numbers all over the place with my own kits,this is why I don't like quoting HP numbers. I know it sells parts, ie why Fundy has always quoted them. It's also been his down fall because after a customer gets back from the dynos they a very disapointed. Don't let this be your down fall too,you are better then that. Please don't go round about this with me,no good will come of it,just stick to what you know for a fact your self.

Four Stroke,

I got no problem with you and I won't do whatever you are trying to do here. This has nothing to do with you or four stroke tech.

I think I am allowed to form my own opinion and work with who I want to. Besides I didn't say anything about Four Stroke Tech.

I do standard bore in my rhino too and it has won two championships. I personally like standard bore kits. I like spending the least you have to to accomplish the goal.

Everyone else stay tuned to the work, will post as we go.

Please don't play games,you know what you are doing. It don't matter who's 840 kit you are talking about you are wrong in everything you said about them with no facts of your own to back up what you said. I don't care if you go with the over priced Fundy kits they run about the same as mine after all that's where Fundy started,selling my stuff. You could have made a post about your new project and never said anything about 840 kits. You know we had a little talk through PM's where you think I put you down, don't do this kind of stuff and play your games. Just give out good first hand info that you know for a fact. Again repeating someone else finds when you don't know them to be true or not will only make you look foolish.

Settle down,you want him to keep giving good info,right. That's what it's about to me,he simply gave out second hand info that is wrong. And yes there is a little beef he has with me and IMO this is a dig at me. Who else sells 840 kit? I'll let my kits speak for them selves.

Have you ever heard of a 840 having warped cylinders.NO!

Have you ever heard of a std bore out running a 840. NO!

No one is perfect,we all have our little problems. Todd has a little problem with me and he admitted it when I tried to take care of it in PM's. I can post it up if you want me to.

I'm sorry, I should also add 800, 820, 900 and 1000 kits too. Should not have singled 840 kits out but it seems the most talked about.

There are a bunch of new kits and most good I'm sure.

Again I like the standard bore stuff.

Heck you get a nice gain out of some standard bore wiseco pistons and hot cams, it depends on what your goals are.

Mine are a good gain without having to spend the money to bore, carbs, head work etc.

Example: One particular company advertised 62mph on a rhino 700 and they are great company but the parts needed was about $3000 to do it which included head work. Our race Rhino with about $1800 worth of mods ran 68 corrected via GPS 65 and got there quickly.

I have always said there are people who want the most they can get no matter what the cost but they are not the people who we cater to.

It is only a small percentage of UTV owners who will go internal of engine and even smaller percentage who want to spend $4000 on going all the way.

I'm against stroking one too.

Mickey, I don't have a problem with you. You explained what you said, I'm ok with that. Again this has nothing to do with you or Four Stroke Tech.

That was a very nice post. You say you want to give the best bang for the buck,maybe you can tell us what would make you go with a Fundy kit vs a std bore FST kit. I mean you are paying alot more so there must be a big difference between the two kits. That is if there isn't anything else behind it.

Todd are you going to test a 800,820,840,900,1000 kit against your Stb kit or are you taking others word for it that you will have a better machine? I agree the 840 kit is the most talked about and there are a few of us interested in your findings. I tend to lean towards the 840 kit just for the torque numbers but would like to see what you find?

I hope I dont add fuel to the fire here, but I know Todd, you take pride in testing a product before you promoted it or sold it. In this case you are going soley off of Rays word, which I and alot of people have heard over and over again, and not your own findings. It would be next to impossible test his st. bore against every engine kit out there, but in the same sense there are ALOT of very satisified 840 owners out there with NO issues! For you to state of the problems out there with 840 kits is not true and not like you. The 840 is great gains just with pistons and cams, you dont need bigger carts, porting and so forth to have great performance. Sure bigger carbs and porting will give you more, personally for woods riding i wouldnt want anymore than just a 840 with stock carbs and porting. For dunes or desert riding, yeah I would want more. The 840 resoponds better to those additional mods than a st. bore would. And as far as bang for the buck, the four stoke tech kits are the best deal out there!!

And that is what I was saying. I happen to know there was more to this so I made it known,simple as that. Everyone knows Todd tests everything and knows what he is talking about before he says so,and this didn't pass the smell test.

Nothing else needs to be said other then if anyone wishes to know the difference in the products,service,performance or cost we can talk about all that anytime you are ready.
