    i guess we can just throw all the physics out the window because you say that the parts are not made. venolia will make a custom piston (have to buy 10 at $100) to fit ANYTHING and you can specify the weight. manely will make you ANY valve you want. you said mods cant make higher rpms and i say they can. i did not say you could go to dennis kirk and pick up a 1000 rpms. race bikes are made to spin spin spin and that is where the power is. i would also bet probe would build you a nice custom h beam rod that could handle the power. i did mean to say lighter VALVES not springs. that was a mistake on my part. ligher springs would float the valves and make contact with a piston.

    on a side note. i dont see why anyone would spend $1000's to modify a 350x when a stock 250r will still smoke it??? you MAY be able to make a 350x keep up but put half that $$$$ into a R and you will be screaming.

    ok since you insist on pushing the issue i will elaborate with my usuall attitude.

    you obviously have NEVER built a 350X motor therefore your showing your ignorance when arguing with some who has more 350X experiance in one month then you have in your lifetime.

    yes you can always find someone to build you what you want, but why? there is a reason these parts are not avalible from the aftermarket because they DON't last. do you really think i never tried any of the things your talking about? we are not talking about drag motors that only last seconds.( i need more then a few seconds to give me a thrill) we are talking about real world off road so leave the pavement comparisons were they belong. if you had ever built a 350X you would know that using lighter then stock parts is asking for a motor failure especially if you increase H.P.

    a stock 350X makes it's peak H.P. at 8000 rpm's but maxes out at 11,000 rpm's why add more rpm's unless you move its peak power to that limit.

    finally i put over 7000 into this 350X and no stock R will touch it in its intended purpose. don't think i know what i'm talking about well i do as i have a 250R and i know its place and it is far from stock

    WOW :shock: we agree on a point. I DID say some mods would increase your RPM's.. I am glad you could figure that out.

    I never said i built 350x's or that i would build them. I do build lots of engines for other items.

    so it takes $7000 to keep up with the R. put $3500 in the R and eat some dirt.

    he wants to go fast, that is his goal. i dont remember him mentioning building an engine or riding on some long gone MX track.

    and i have never actually rode my tecate's, that is why i mentioned the the 250r. i have owned a few of them and i have modded a few of them. they are great trikes for racing.

    i started the tecate projects because i was bored with the 250r. i use my trikes as a hobby to pass time, not as my life time passion.

    i said some mods WOULD increase your RPM's. if you cant dosprove that then you shut your pie hole.

    i can change my gearing, it is called the ring and pinion gear, ever heard of it?


    i was not responding to airman in my original post, i was just correcting an incorrect post.

    get back to the original subject and quit stepping around it.

    SIDESTEPPING is what your entire post have been about. i just replied to your misinformed mind on the 350X subject.

    yes mods can increase your top rpm's...BUT NOT ON A 350X. it's been tried and failed. it already revs more then it needs. all you can do is move to power to the rpm range you want.

    so you agree with me????? i said mods could increase your rpm's i did not say that the 350x could handle it.

    all i said to the guy was mods can increase your rpm's and you just agreed to that.

    thats all folks. 8)

    you sure like to try and twist things around don't you if your gonna quote me use the whole quote not just a portion of it to suit your needs. I SAID..."yes mods can increase your top rpm's...BUT NOT ON A 350X" and that is what this WHOLE THREAD IS ABOUT 350X

    re:

    Mr. ATC

    This is off topic but those tires you have on the rear of your X I have the same ones. I was wondering where you use those. :?:

    they are just one of my all around type tires i have. i actually use them very little. mostly just for playing around when i don't want to waste my good tires for horseplay. i normally run turf tammers

    I thought your 350X got stolen? Did it? Or did you find it? :?

    OK...now I am not an engine builder or anything like that either. BUT, I do know that if you throw in a lighter piston, rod, valves, etc...THE 350X WILL TURN MORE RPM'S. If there is no rev limiter, and it will turn 10,500 stock....then if you throw lighter accessories in there it will rev higher. No, I'm not talking about 5K RPM's more, but around 500 or so.

    Pick up a cinder block and throw it....now pick up a brick and throw it. Now, which one went farther? :? (the lighter one right)

    i don't disagree with this, but those parts are not avalible for a 350X because they won't work without destruction. yes you can have them made by someone but if you want i'll make you a wood piston with 15:1 compression. does that mean it will work?

    REMEMBER WE ARE TALKING ABOUT A 350X MOTOR. NO ONE MAKES LIGHTER PARTS TO SELL OR USE FOR A REASON
