Re: i love my life
I dont know if they will fit the same but I'm going to use cbr 600 f2 wheels and brakes on my KX. I paid $112 for everything and all I need to do for them to fit is make spacers and get custom brackets made to hold that calipers 
Just a thought, alot better then going and dumping a grand on rims.

Re: i love my life
i've heard a bunch of ppl say the hondas are junk for valves and they only last about 12 hours worth of riding if your lucky, i know guys that race every weekend and constantly replace them after ever final cuz they wear so fast, i guess its someting to do with the unicam system that honda runs, and i know that when they released the honda 150F they used stainless steel valves cuz most parents would have a **** fit if they had to replace valves every other day for kids to ride, they deffinately can have some sick power but i wouldn't have went honda just for that reason. just my

Re: i love my life
How are spacers and brackets going to be alot of money? Neither are that hard to make, and yes I have a friend that owns a choppershop with all the machines that are needed.

Its not the valves or the cam. believe it or not it is the intake valve spring that gives the valves a short life. The intake spring cannot control the valve during high rpm's. When the motor is turning fast the valve looses contact with the camshaft as it is closing....in this case the valve slams into the seat. Stiffer valve springs will control the valve better....instead of the valve slamming into the seat the valve would use the trailing edge of the closing camshaft lobe to ease itself into the seat. If you really think about it its very much like over jumping and slamming down a jump vs. landing on the landing ramp. Now do that 30 billion times.......

Re: i love my life
Im serious.........Im not ******* you at all... time is money and there is alot of figuring to make a piece of metal to line up correctly to not only fit but to clear other moving parts. God knows how much a shop will charge to make a bracket. The spacers are nothing but the brackets.................
I mean look at a dirtbike oversize rotor bracket (they are mass produced and they still retail for 80 bucks and its just a little piece. I work for a floor company, we were charged 300 bucks to have a 4 foot curved piece of oak threshold made. I know this is different but the same thing will pretty much happen with those brackets.

Re: i love my life
I think the big issues with the Honads wasn't valve float but more that because of the unicam setup they had some weird *** valve angles. We pulled a crf450 and yzf450 apart in the spring and compared while they were apart, definate difference.
As far as the street wheels go.......it's not too bad. We put a set of f3 wheels on an 03 crf450 and it wasn't too bad. A little bit of a pain but no big deal. You just need to machine a few spacers then measure out the brackets. Do it yourself. He is right in that if you pay someone to sit there and design them you are hit. But if you have the time to measure and line everything up it's a cake walk. I think total time invested on makng the f3 wheels fit was like 3 hours.

Re: i love my life
The uni cam has nothing to do with the wear of the intake valves. The intake valves are ran directly by the camshaft (shim under bucket design) just like every other motocross 4 stroke out there. Nothing is different between the intake valve mechanism of the Honda verses the other 4 strokes. It is the exhaust set-up thats different as it of course is ran by a rocker arm (unicam) and this rocker is ran off a separate lobe than what acctuates the intake valves.

Re: i love my life
I had an older Honda XR dirtbike and that thing lasted all the way up until I wrecked. Hondas suck when you hit a fence in a cow pasture at night at full speed.
XR's are bullet proof.

Re: i love my life
Do you guys know where I can get the stock CRF 450 springs?
Mine has Pro Action Suspension, Its setup for a 200+ lb. rider.
I need to get the stock ones rated for a 150lb. rider.
Kinda left field but it does'nt hurt to ask.

Re: i love my life
LOL my answer for everything is EBAY...Id say you can get front and rear springs for 40-60 bucks...plus you can sell your existing springs and get your money back....good luck
