explained in a fashion only an engineer could love. however, couldnt you change that with an aftermarket sterring stem?

HERE IS YOUR CHANCE TO MAKE MILLIONS!!!!!!!! I will sell all four of my yearbooks as a packaged set for a total of $500,000.00 Get them before i'm famous! its a fuckin steal guys! a guaranteed winner

ya the people are the only reason im still here. recently ive been hittin a new forum. its pretty small, but it gets hitup by a few reputable builders. dan wade and such. lemme know if youre interested.

resembles a silver wing. i dig it.

bought time you showed up again. whats up dude?

absolutely. i still got his email its [email protected] send him some text sometime. i do every once in a while, but havent recently.

no, hes only got one mortgage on his house. the sanddragon arms look of pretty good quality to me, how much will those cycle?

i tihnk ive heard like 450 a set. but dont quote me on that.

thats apparent. so what is walt up to brock?

oh wow. ok not that much power. thats just rdiculous. ill post up my motor specs when i get it completed. and im gonna get a digital tach from work so that will show my rpm improvements.

haha, not by a long shot. that 250f will eat that xr250 alive. xr's are turds compared to a new 4 stroke.

ive had 2 dealing with cotton eyed joe recently, trades, and both worked out excellently! NYUK's the shiz. havent dealt with the other two.

you have no pipes? like just bare ex ports? that doesnt seem healthy. but i bet the topend is decent. the bike's got you, they hooooook and the 250 4 strokes are no joke.

im sure once you got that panzer II spooled up on the inside it would do into the 60's. but i dont think id trust it. lol

ok here is what i have so far, nothing ordered yet, i need to finish chassis work. the mods i saw to make mucho rpm (for a lawn mower) were very simple, and equally cheap. you start with removing the governor. this takes the revs from 3600-4000ish to around 5000-5500, depending on your blocks condition. from then one would move on to heavier valve springs ($12 per set) to keep the valves from floating, as well as an enlarged oil dipper ($10) for better lubing. the springs arent necessary though. since i am dealing an older style flathead motor, floating valves does not mean bent ones, a good thing. it merely mean the motor will no longer rev for the obvious reasons. the super-duty springs keep the valves stuck to the lifters better and thus push the rpms up there a bit more. this brings us to the next weak link, the piston rod. at this point rods start to warp or break, time to employ H-beam technology. CNC billet rods, in "H" or "I" configuration range from $45 to $75, that is super cheap. at this point its cost prohibitive for me to build any farther. but rest assured ill be wiring a tach ASAP, to record actual results. now we are running lean, with the help of a uni filter and 12inch dumped header. for that im looking into slide type motorcycle carbs. my buddies at the shop build xr50's and have many spare carbs leftover from high perf replacements. some time next week i hope to be machining my intake manifold to adapt the two. from then on i am going to TRY to tune it with the exhaust gas monitor at work. the problem being its designed for big street bikes, but it may work. if i cant get the power or jetting i want with the xr50 carb, up ill move. the next size i see fit is an xr100 carb. the builders i spoke with recommended a 125 4stroke unit, but they are also building more than a mild motor. does it really seem that simple? or am i missing something? i like to think that im not, however speed is never cheap. give me your thoughts guys, i need to have everything into account before i make my intake, maybe itll save me some lathe time.

yep any coil should give spark. try one off of pretty mcu anything. however, getting it to run wiould be another trick.

.......and it happens quite frequently.

whew. i thought i was gonna have to make that comment.

RJ makes a hell of a point about bubba. its true he turned 250 lap times on his 125, but the difference is the traffic. im not a bubba believer and never will be. i see him as a sparkle and fade kind of guy. and why are you guys using RC as the benchmark? doug henry is the man for sure. that dude is almost forty and still turns Very Very competitive times. larocco, hes a fast sumbitch; just a hair of a level under rc chad and k-dub.id like to see him win a couple, but a cup would be sweet. given all that, give stewart 2 seasons (one is toast). see if he doesnt grow up. if he does we'll se it, if he doesnt hell be sweepin floosr in walmart.

WOOOOOOOHOOOOOOOOO im drunk before you!

starschmucks, hahahahaa

swig a beer before you hit the gate at the dunes, then ide until your thirsty again. repeat.

reservoirs are like a radiator and add cooling benefits to your shock oil. the rezzies have a floating piston in them that has nitrogen (typically) on one side and the shock oil on the other. as the shocks compress oil is forced into the chambers and displaces the gas. basically they add more oil and a larger surface area to beter dissipate the heat generated by friction. this heat reduction makes the oil keep is viscosity better and makes the shocks work like they should instead of just acting like springs.

i with meat head on this one. to me nikasil and a wickedass port layout are totally worth the coin. even if you were to run them on a stock motor, pipes included.
