Atc 88 dyno results look!

Nice collection! I really like 70s and the A+ frames. I still gotta ask what your basing your opinion on you say you know 70s and it looks like you've dealt with a few you've got a fine collection but if you don't know what one of em makes for power why do you doubt so much what mine makes. Like I said its a Mustang dyno and the load cell was just calibrated. I'd like to see what some of yours are puttin out! I'm sure you've got a good feel for power by racing em but if you don't know what yours are making then how do you know mines inaccurate maybe yours are over 20 horse obviously mine doesn't make near the torque bigger trikes do but little engines have the revs to get the horsepower up. I definitely need to go up a tooth on the front it'll do 48 like I said with stock gearing my only point ther is how high its revving I'd like to gear it up a bit and see what it'll do.

http://www.muckandfun.com/index.php?...&id=6&Itemid=7 Scroll down the the brand new 160cc race motor and read its "APPROXIMATE" 18 hp. rating. That motor is twice the displacement of yours with absolutely all the best stuff money can buy and it is still quite a bit shy of 20 hp? Not saying it is not reachable....but that is where I based my hp findings for my yx150....from the factory specs they gave me. It would cost me 2000.00 in upgrades to get 2 more hp's out of mine. Nice build...we are not trying to haggle ya.......that is just a number I have a hard time believing when compared to some of these big bore newer motors. Great stuff still.

You can calibrate dyno's to say what ever they want though. What was the correction factor, if any?

Good to see some other HP ratings. I just wanted to see something other than opinions Ive never seen what those big bores are making. Certainly if a 160cc monster is making 18 HP the dyno was off on mine cause mine wouldn't be close to a 160. I just wanted to see some other ratings thats all. Thats exactly what I wanted to see, thanks for posting CRAZY70MAN!!!

You are welcome. I don't beleive anyone here is trying to tell you "I told you so" but there are members on here that eat,sleep, breathe 70's and the mods for them such as Kasey and others. I always am willing to learn or try a new trick and or listen to someones ideas, thats the way we all learn. You have some interesting points and ideas.

even though some people eat sleep drink 70's or think they do, or think they r god here which i personally think is more of the case, no one has posted dyno numbers. and no one has talked about the mods done in this case as in depth and what it is actually changing. who knows.... but i would never discount it without 100% proof. thats just being ignorant to act like u just know he's wrong. but on here...... its expected to c that response.

Some of Kasey's 70 builds look like God may have built them..........lol..........

The most you could EVER get out of an 88cc air cooled 4 stroke would be around 8hp. Dyno was definitely off

Love your build though! Awesome work regardless of its HP.

Here is another dyno chart from Sterdy with an 88cc kit and their performance pipe. Tad over 5 hp. http://www.sterdyproducts.com/produc...8&idproduct=50

Well... ^^That helps make my decision, on doing a 88cc kit, or a lifan motor swap... Lifan it is!

Exactly what I was thinking.
Lifan 125 with kickstart it is!
Make a custom lever for the rear fenders so its like a big red. (Swings up backwards) and we will be good to go!

well i still after 32 years of riding 70's i still have the passion for them unmatched by 90% of you guys,, just ask me!!! i do not need a dyno to tell me anything,,, it would taks a specialized dyno to be accutate with these small hp motors,,, i do know that,,, and i can tell you with a pretty good amount of accuracy from the list of mods to his motor its not even close.... HOW you ask??? well lets talk about it,, first of all i see no timing advance,, you need alot of timing to use that amount of rpm's... stock 70 have NONE ,,, so when i built a 95cc 70 motor.. YEP 95 cc's you can go that big ,, with about 12 to 1 compression,,, i didn't use a stock 70 head either,, because it has no bearings on the cam,, and the betrice cam has very small diameter bearings ,, which help but at 10.000 rpm's hinder also,,, i used a xr70 honda head with large diameter bearings,,, the head was flow ported very nicely i also used a 24 mm carb not a 20,,,, more air more power at higher rpm's.. as far as timimg i used a ct 70 flywheel which has a built in centrifical advance much needed,, also the flywheel ia aluminum reducing rotating mass ,, after spending A buttload of money I installed it in a chassis to see what all the hard work had yielded,,,,, wow big power alright ,,, then i finished the install of the PITSTERPRO 155ho.... well the 95 cc build is on the shelf as much power as it did have ,,,,, the 155 seems to be DOUBLE THAT ,,,,,so believe me i have been around the block for many years with 70's everywhere from my garage to parts in the dishwasher,, so a dyno really means nothing to me... get me a video i will tell you all you need to know,,,, and if you want to build a HOT ROD 70 call me i will be glad to talk about it for hours!!!!!! OH and ITS OK TO USE MY NAME IN YOUR POST!! i have broad shoulders and i can take it ,, no sense in beating around the bush!!!

believe me i do not discount the knowledge u have with 70's or any trike for that matter. its far more then i know. i read about and watch all the builds u do. they r great. i just disagree once in awhile on how people go about things. and i am not saying just u..... i know its how it is, and it won't change. just have seen it all too much on forums. i guess its just something that bothers me too much, or i think about it too much when it doesn't affect me in any way.

and i as well thought wow 16hp?? but i just didn't know 100% for sure. i understand now how u did know for sure.

anyway. i am starting two 70 builds. one basically a stock restore and hopefully a suspended 150cc for the other. we will c, lots of other projects at the moment, but i chip away at a little on each here and there.

[bigworm626]

We have a verdict: Kasey is God of the 70cc. Like they used to say in ECW... Holy Sh!t!!! Holy Sh!t.
