dont have a 125 but im pretty sure that ATHENA makes a big bore kit for 125's that brings it out to like 145 or 150

 

[drag lt guy]

you dont really need a big bore. just send it to flotek and get an agressive trail port

 

[00_yamaha_man_125]

y do u say send it to flotek

 

[drag lt guy]

good prices great work. most companys your paying for a name is all. flotek is run by a member on here eviltwin and he will work wiht you and give you his full ability on the port job
what im saying is evil knows his stuff

 

[00_yamaha_man_125]

is there more of an advantage of get it ported than buying a big bore kit. i have read that a lot of people send the stuff to evil and only herd anything good about his work . i was just wondering if a big bore kit is the way to go

 

[drag lt guy]

what kinda riding do you do?

 

[00_yamaha_man_125]

trail riding mostly i go to the tracks every now and then with my friends but that it

 

[flotek]

the big bore 125's ive see nand know if often have problems they dont offer enough transfer and crankcase area they wont run much better than stock and usually overheat ...most guys jus trade up for a 250 bike when they are read yfor me power ,porting a modern 125 definitly helps but it isnt going ot give massive gains like you might see on some older style quad engines

 

[00_yamaha_man_125]

what will the porting improve the most

 

[flotek]

probably midrange to topend

 

[00_yamaha_man_125]

how much would that cost to get done

 

[drag lt guy]

depends on what kind of porting you get. i personaly would recomend to get the V-force reeds and maybe a bigger carb with an agressive trail port. it all depends on how much you wana gain. if you were drag racing i would tell you to get the big bore and port it all out but you just trail and track so that would take away reliabilty

 

[drag lt guy]

corectt me if im wrong but i think evil charges $180. which is cheap if you would compare to big name company's prices like $400 and up

 

[00_yamaha_man_125]

i want to be faster but i want it to be reliable also

 

[drag lt guy]

i would recomend cheaper things than a big bore. as for the agressive trail port and V-force reeds. maybe even a bigger carb

 

[drag lt guy]

with those mods i would say you could easily walk away from an unported big bore 125

 

[00_yamaha_man_125]

what size carb should i get if i get it ported

 

[drag lt guy]

getting the carb after a port job is not a must. umm. what size is stock and i should be able to tell you from there

 

[00_yamaha_man_125]

im not sure ill tell you later when i get off work
