Look man I shouldn't have gotten personal.  The helmet is fine (not as good as full face) but if that's what u want to rock, bandanna and all go for it.  What is frustrating the #$%* out of me is the danger you are putting yourself in.  Your right people crash bikes, and they end up in salvage yards like yours.  If you bend forks or frames, you replace them you don't roll on them, or bend them back into shape.  You kept saying you were going to ride this frame to check out the other parts/systems, this is a #$%*e idea.  You came to this site for advice, just like the rest of us, but you're not listing to the message.  All the experts are telling  you not to use this frame and your response is always oh it's only off an inch or oh I'll only be doing 35 mph.  Hence my verbal #$%* slap, hoping to get through to you.  Guys are talking about wheel balance, tire pressure, swing arm bushings, minor things when compared to a bent frame causing tank slappers, head wobble etc.  I think your coming around but I'll say it one last time just to be sure< Don't use the F*in bent frame!!!
Respect!

na dude i totally respect im a little think lol

Good call on the helmet.  I looked up percentage damage on helmets a while back, and around 90% of accidents that cause damage to helmets have damage around the face.  I'd hate it if you dropped your bike and lost part of your face... and I think you would too.  Play it safe, you never know where trouble will come from.

You could always weld fill and grind those notches out. Honestly, the most insane thing I find about the whole thread is the fact that you have a junkyard that has and will sell motorcycle frames and parts. I couldn't find one anywhere near me.

have seem some tremendous tank-slappers on the intranets where not much can be done before you fall off and go BOOM! but mine was relatively benign.  trying out a bike and got into trouble, luckily no get-off.  severe bar oscillation side-to-side on decel.  did what i heard what might save me, that is:  loose grip, steady throttle, slight rear brake.  oscillations were reduced such that i got control back and returned the bike to the owner.  worn swingarm bushings, head bushings and tires.

mine was like rodeo sex, but with a loose grip. ;)

its like any other family owned operation. you just have to haggle with them. i mean they help you out and all but its not like a guaranteed it just needs a new battery tires and carb rebuild

i would imagine there is inherent risk when buying a bike like this especially an old one and try to fix it up.

when they get bikes they dont really go over them they just place them in the yard. i made sure to do everything else. checked the vin on the frame and engine, kicked the bike and made sure to get the one that felt better, check to see if the carbs are right, the airbox is still there, the forks are good and not bent, the least pitting on the exhaust and frame, all intact electrical system, good controls like the starter and horn button etc etc, and all that other jazz. i just didnt know much about the frame angles and rack angles and stuff

i will try to haggle with them and i think $100-150 is a far price for another frame and title because i know this place charges double for a frame with title.

mostly i would imagine they just dont want to lose money. 1hr of labor for paper work, the state fees etc and $100 is what im shooting for.

so idk thats where i stand on the whole situation im not really going to #$%* to hard because 1) the mom is super cool with me :) shes been discounting and giving me free parts ( both those k&n cb550 filters and bracket, left controls and a slew of misc parts) 2) there daughter is kinda cute  :P

so idk its all good

guess ill just get the title for my second frame and try to sell both to recoup some lose/profit granted ill let them know about the damage but people still like to chop and weld

i still think my second frame is good other then the highway peg over tightening on the front down tubes.

ill take some more detailed pictured of my second frame i just never thought id use it so i havent really taking the time to go over it completly

ya i would never have done this kind of build without the place. doing all this from ebay i probably wouldve killed myself. if it wasnt this i was going to be that douche that bought a moderately wrecked cbr600rr and put a full crash cage, a 12 o clock bar and a bigger spocket and turn it into a stunt bike

I wrecked my bike,a cb500-4 , in '04 on my way home from a 5000 mile ride.
got sideways at 65mph hitting the grass at the side of the road and sliding til my tires caught the edge of a concrete driveway into a restaurant,the bike stopped,flipped me off sending me flying.
landed on my shoulder,broke my shoulder blade parrallel to my spine but about two inches away.
I survived the wreck,bike looked fine except for a bent brake lever on the bars.
got back on went up the road to a repair shop borrowed a torch heated and bent the lever back straight,and  rode the rest of the way home(900+miles)with a broken shoulder.
have been stripping the bike to freshen it up and found that my frame is bent,rear supports where shocks mount are offset to the left by approx 1 inch and steering head is off by three quarters of an inch. hard hit when it flipped.
I've been riding this bike this way for so long I dont think I will fix  it,still rides fine,can take hands off bars at any speed with no effect as far as I can see or feel.

tank slappers are almost always caused by worn parts,or bad design in the first place,I have had my share cause maintenance was not my strong suit back then.

not to hijack thred but...have any of you ever ridden up on the cement wall that is usually on the outside of a hiway ramp?

had a kz440 that happenned to me on,scary when you cant get traaction and the bike keeps workin its way to the outside of the lane, then accross the shoulder as your tires get to the barrier and cant go further unless you go up the barrier, which I did at over a hundred on the clock.
the hard part was getting back on the ground before the barrier ended.
that was a wild ride,the sporty I was racing at the time gave up when he  saw me on the barrier parrallel to the highway when I passed him,LOL. good memories,good memories.

ride long enough and hard enough and you too will have stories like this to share too!

Thats not true, do you ever watch world superbikes or moto GP.? Some of the best built and handling bikes on the planet and they still get tank slappers. Poor maintenance can also cause it but it is a phenomenon caused by multiple things including poor road surfaces. The slightest bump at the right time can cause tank slappers on any bike..

in my opinion motogp and superbikes are designed wrong anyways.
all my knowledge comes from seat time on a ROAD bike.
all those crotch rocket style bikes make me feel like i'm over the front tire and heading for the pavement just sitting still, dont like the riding position at all.

remember this is just MY opinion.

It fine to have an opinion but what i quoted was a blanket statement.

All the technology comes down to us at street level from racing, yes those bikes are built on a knife edge but they are at the forefront of motorcycle technology and are the benchmark when comparing to everything else. Why would you think they are built "wrong"? They are designed to fit the rider for perfect weight bias so they handle as intended, they have the best suspensions and tyres money can buy and whilst you may think they are uncomfortable to ride, they are perfectly comfortable to race on as designed. If the 750 is a bad design {i have had a monumental tank slappers on a 750} and the modern superbikes are built wrong then what is right.? Crotch rockets are designed to get the riders weight forward increasing cornering ability and front tyre traction, { going for a 50/50 weight bias} you couldn't corner as hard on a sit up and beg riding position.

back to exsmooths original question,,this is your first bike?and youve never ridden a motorcycle yet i think you posted once?do you know anyone who has a trailbike you can ride somewhere?or is there someplace off road that hires dirt/trail bikes you ride on site?even if they have auto clutch but manual gear select?dont try and ride a full on motorcross bike just a trail/dirt bike,,this way youll get a feel for things like clutch and throttle control,rear VS front brake control,,most guys who start out on trail/dirt bikes make better riders(im ready to be flamed here),you can crash a dirt bike ,dust yourself off and go again 97% off the time riding within your limits,i always say you have to learn how to crash!learning on a lighter dirt bike shows you what to expect on bumps and bad camber roads etc,pot holes and locking the rear wheel to control a slide on purpose,,i think you said your going to take a course etc and if you can also ride on dirt somewhere without pavement/signs/rules you just learn the bike without all the putting on your indicator and so forth,,you can read all you want about how to ride and how to correct and how to react etc but you wont know or actualy learn untill youve done it.
