well....i am not going to make another long post stating prices of modern bikes. the last time they made a 300cc 4 stroke was eons ago. single cam...blah blah blah. 2 valve...blah blah, non coated cylinders, air cooled...so on and so forth
i made my living the past 15 years doin this stuff....

go to rockymountainatv.com and price some things for modern rides. 2 cams, 5 valves per cylinder, nikasil coated cylinders.....technology in the quad world/dirtbike world has changed on the 4 stroke side. the valves for my z400 are 60 bucks a piece, and theres 4 of em in my cylinder head, not to menion dual cams, they run almost 400 dollars, and if i need a piston, 200 dollars. if i need it bored, well...theres the machine shop charge, then it has to be sent out to be re nikasl coated. you cant just bore and hone and toss a piston in them anymore. a topend job will cost close to 500-1000 dollars on a modern machine if you do it correctly, depending on parts and if you do the labor yourself.
regardless, if you plan on racing motocross...the ttr 125 is by far the {flaxulation} thing from a motocross bike.

the thing on a 2 stroke you need to pay most attention to is compression, and jetting. once the carbs jetted right..no worries. i always rejetted any 2 stroke i bought just to be sure i was right, you never know what the last guy did. temperature wont be an issue as every 125cc 2 stroke bike has water cooling...as for pipes, you have the run of the mill fmf, overall power, pro circuit..mx powerband, trinity..all out race. there are no bad 2 stroke pipes on the market anymore (besides dg). as for 4 strokes...theres a huge difference in pipes as well, you can go with a slip on, leave the stock header, or you ca go full system. there can be as much as 4hp difference between pipe brands on 4 strokes...2 stroke is just a matter of where the power hits the hardest, which is where the pipe design comes in. long, fat chambers with short stingers produce alot of top end power wheres and narrow short chambers with long stinger section produce more power on the lowend and tend to drop off power at higher rpm's. then you add on silencer lenght, and diameter and theres a whole new ratio to throw in the mixture.

this guy knows way to much and I like it.

[gokarter45]

Those spindles are easy to that why im getting new reinforced ones. And yeah Ill go check that place out the reason that if be nice if i got a yz 125 is that it be race ready for when i do motorcross.

okay u know alot about bikes find me what i need for my cz 125cc 2cycle racing engine

[jeremy]

so what is it you need?
year? street or dirt model?
being its a Czechoslovakian make, it may be hard to find performance type parts. you always have the option of sending the cylinder and head off to be ported and polished. the biggest bang for the buck for performance is porting. its not something you want to do on your own. there is extensive research that goes into each cylinder to optimize flow and port timing. you can also have a custom pipe made to match the engine porting and flow.
this place has upgrade carb kits, pipes and i'm sure they could hook a guy up with some engine work.

[gokarter45]

Damn thats good place for them. Can you show me were i could get upgrades for a yz125 or a ttr 125

[jeremy]

i buy all my stuff from
motosport outlet (google it for the website)\and RMATV.com

i took my 02 blaster that i had from bone stock (55mph) 200cc 2 stroke to a 75 mph machine and never even tuched the lower end of the engine. my next mod was going to be a stroker kit and some serious drag port, but i traded it off.

[gokarter45]

yeah that stuffs a B**** to get off with all the old corated parts.

[smgs92]

[jeremy]

[gokarter45]
