no i disagree. my fathers old MX bike in the 70s bent and broke stuff all the time from jumping too big.

newer bikes are built amazingly well to handle the abuse they get from todays ignorant owners

Just like cars

Old cars is an old mans sport.

Seem like every one is wanting older cars now,, my brother in law just got Plymouth scamp and a gremlin,his buddy has a fastback,,,his dad has a Chevelle my neighbor has 5.0 my homeboy cris has Nova,and working on a 64 Impala,I like the Novas and Chevelles, the gremlin is the ugliest car I ever seen. Dudes like them old cars around here,i definitely think there better built.now days everything is built in China its all about the dollar and not the workmanship, do you watch Speed Channel????? what is it you see?????

Nowdays a supercharger or turbo on a Dodge Neon will do it,no raw power look at the hemi look how it changed how they tryed to bring it back, my uncle has the Dodge rumble bee I have a Chevy Tahoe we race he.beats me by little, Tahoe with a heavy truck, they just don't make them like they used to.old cr500 are still alive and they will eat any dirt bike you can buy today.old vs new I vote old

Im 32 yo I like something old styles,I like the style of the old cr,,s and some real American Muscle if I had the money I would buy a,old project car and bike

Ok forget all that bout the cars. I vote new. Point one suspension technology way better now (I.e. no more dual rear spring setups, air shock front forks,usd forks ect.) Two, with better technology comes better understanding on how to reliably get the most power out of a given engine. Race any 2013 bike against any same cc (and stroke) from 20 yrs ago. The new gona win.

New frames designed to flex instead of break bc the manufacturers know exactly what kind of stresses are being exerted. FI better than Carb (least most would agree. And plastics vs. Metal sheeting, plastic is cheap. You mess it up rip it off throw it away buy new. Can prolly get plastic gas tank new for 100$. Could prolly get new metal gas tank 20 yrs ago 150$, but that like 500$ now.

I race a cr 250 2 stroke and we are neck to neck pretty much,the bikes older smaller and just as fast as mine,a cr 500 would smoke both of us without question, shocks did not change much over the years,the 2013 shocks did on crf450r 1 socks for going up 1 socks for coming down, that's why I bought a 2012, I did not want a experiment bike, shocks didn't change much over the years.think of it like this a old cr500 when do you have to rebuild it,a new crf450r powers not close when do you have to rebuild it, if I told you with the owners manual said you would trip, I'm not talking historic bikes,but older and the plastic on the cars cost just as much for repairs, Labor, paint my Ultima is plastic its good on gas nice car but its plastic, the front bumper cost the insurance company as much as my steel bumper on my truck. this is kind of a personal preference conversation, some people are out with the old in with the new, everything I own is new,but I still have to vote old just off what I see,,, let's see if we see plastic cars from now in 50 years like we do the older ones, I watch Speed Channel every night,every now and then I see new cars 99% are older American Muscle

I heard older 4 strokes are a lot slower than they are now, While 2 strokes had always threw your front end up!

I was talking 90's not the 70's I just wrote that because I felt that my friends 1995 xr80 and my 1991 cr80 looked better built then the newer stuff, not just thrown together in a factory with no pride in them in like older bikes/ vehicles

That's how I see it, it's personal preference but I like the old cr500 style bikes,if I had the cash, mechanical skills I would restore one

Hope so, I change oil, transmission fluid, air filter, oil filter every ride. I'm past the break in, ,do u think I should take it and have the valves checked, probably 20 hours in

check the valves yourself sean. its a simple procedure that you cant really screw up.

A Manual....

I'll buy manual and thickness gauge,im going to need your help never done no internal work,I have all basic hand tools.I want to learn to do all the work myself,

Im at about 20 hours, some dudes said check them some dude said don't.I still want to have all thats needed,when should I do it,what hour mark

Shims to right

Ur valves ain't gona need changed, put ur wallet away killer. Most vehicles recommend checking them after first month then every 6 mth there after. (Unless ur riding the crap out of it) . You don't even need to buy a whole shim kit. If they need adjusted (doubt yours will) figure out which ones you need and go to dealer an buy them individually, there only a couple bucks apiece.

Just use black permanent marker to label exactly where every piece goes, each part is mated with other parts around it so they need to go back exactly where u pulled them from. Pulling tappets easier with a magnet. Be careful not to drop shims or dowel pins down in the motor BC you'll have to fish for them or tear whole motor down to find them, Cam chain can also fall in. Some motors have a bolt to prevent it some don't.

Fyi,I never buy manual anymore. I have them all downloaded to my phone for free. IMO they should include with new vehicle purchase at the dealer I'm actually searching for free download now.

My manual/handbook says competition only,it dont have everything in it,im going to try this im nervous as shlt,but ill try I'm done with the dealer I go to,they called me today and said the c clamp I ordered is on back order for 4 weeks, when I paid for it they said they will have it in 3 days, my camera handlebar mount I still never got, I have a new rear brakes I need this, being out of commission for 4 weeks is not going to happen,I think its a c clamp,I would send you pic I cant figure it out,im going to try to bend it,for now on ill go to ebay an crfs only and moto sport and few others,

2 of them say page not found,the one for 6 bucks says 08 have they changed anything

is this what this fourm has resolved too.

more throttle less thinking

I can't believe you made it this far through a conversation like this without someone bringing up the two stroke four stroke debate... This has got to be a new dirt rider record ! Congrats guys

U dont b trippin now eh

It also said the 500 is 25000 rpm & the 450 11000 so how can this be if the 500 is putting out double rpms it dont make since to me
