how much hp?

[c10-chevy]

how much hp will this motor make ( on estimate) 1985 atc 200x 1mm over bore 12:1 piston bigger cam ( not sure on exact size but the cam lobes are a little less than a 1/4 inch bigger than the stock one) and c16 race fuel, k&n filter, kerker exhaust. im just lookin for an estimate on the power it will make. also where can i find a tach and speedo for this trike. it would be nice to have one, thanks

I would guess about 12.5 hp..maybe more if you had a 5/16 cam

thats not to bad. i would get the exact specs but i dont have a micrometer big enough. im happy as long as it will be faster than stock

i heard they are 17 stock at the crank and the utility 200's are 13

I estimate about 20-23 hp.

You will have to play with the cylinder to help you get some really big power out of the engine. The potential is there though. But big power means you will loose alot of rideability unless all you are doing is wide open throttle riding. Big horsepower doesn't work well in the woods or for most pleasure riding.

i was told that with the setup im going to run that it will have good performance and still be reliable. most of the riding is full throttle. the only reason for using the 12:1 piston is i got a good deal on it and it was brand new so ill put it to use

here's some more info i found. around page 26-27 of this mag scan shows different hp ratings for a kerker set up.
