    ive always liked the idea of a blasted finish. did you use real fine sand or something else ? ive heard of people using walnut shells and other shit like that

    i dont know nearly as much about heads as i would like. with full time job and other obligations its tough to do much real life testing. plus you cant fit much machining equipement in a 10x20 garege when its full of other shit. im sure most people can relate

    check it out. bet this dumb fucker didnt notice a thing and kept on ridin '14 and '15 are using this one. dont really care for it. just kind of rolls into the bowl with no real squish band. supposedly they lost a couple hp from previous years

    i dont even wanna see a cr250 head. heard the newer ones have a intentional converging band. i havent verified it but more than one person has said it. ive seen a few different jap and older ktm head and they mostly used the standard hemi style from what ive seen. maybe there was some variation along the way that i havent seen

    pulling random shapes out of your ass hardly ever works. atleast start with a known good working design and go from there

    a bathtub style, which is what i would call this , works as good or better than other designs. if the shape is correct. IF is the key word. this one dont look like anything ive seen before. he should of looked at the recent ktm heads and he would of been going more in the right direction

    im confused. +30hp with new domes, does that meen it was runnin like dogshit before and now its normal or it was normal before and now kicks the shit out of every other bike ?

    seems like theres a variety of various PV designs. honda,yamaha,kawi,suzuki,ktm all used something alittle different. the only one im familiar with is ktm and it works pretty good. the main port is 67% of bore width which isnt far off from what you would expect to see on a nonPV port. of course you could make it even alittle wider if you wanted. getting to 70% probly wouldnt be a problem. so not all pv engines have narrow main ports. is cheetah guilitine operated by suction from the crankcase ?

    thats usually what happens when the ports are all out of wack

    a well developed cylinder i can see a amatuer grinding away a few hp but i thought that passion guy had been around for a few days so it doesnt make sense. although i knew a guy in cali that ported cr500 for 20yrs and never could make one run any better than a stocker so i guess anythings possible. when you take it apart be sure and get pics.

    remember back in the day when this place was cool. people posted interesting shit like porting even though they hadent a fukin clue what they were talking about but it rambled on for 15pages so it was fun to read. now its just all gay shit like clutch levers and removing tors .

    i bet a small 3cyl would do pretty good. 64mm pistons and 64 on the crank

    $1300 is pocket change for me to

    probly realized he couldnt afford the crankshaft let alone anything else

    that was the bike from dirtwheels ? i have that edition. looked like a cool setup on the fuel system. so you threw it in the trash for some smartcarbs eh. what a shame

    if you dont have a machine to cut your own domes, you may as well just be another average joe with some porting tools. how the hell do these shops now days test anything if they cant cut their own parts.

    what % do you use and is it carbed with pulse pump or what setup you got, cant tell from the pics ? whats the advantage of doing it that way versus a mechanical injection like hilborn ?
  20. registered user
    cool do you got some pics ? wondering how the fuel systems are setup

    i dont see why your calling him stupid. kicking compression goes down as elevation goes up. both sides should be close to the same readings

    website says they mix but maybe call klotz to double check. or dump the shit in your tank to the lawnmower or car
