CT125 Mods and upgrades

[chuckklr98]

Anyway to take out the references to other models on the ct125 page? Some of the stuff has just Monkey, Grom etc on it, but is on ct125 link.

Can't wait to hear a video review of the 181 big bore performance...does Hardracing do installs? If so, how much to install this kit?

until a reliable fuel controller for the trail is available (hopefully soon), you might have to wait for that. Unless you want to go deep into a carb conversion. (yes they do exist.. i'm sure can be adapted to a trail). http://shop.yoshimura-jp.com/en/product/result.php?maker_id=2&car_id=1097&second=17


I can assure you a 170 4v setup is very sweet, i loved mine. But be prepared to fall 'deep' down the rabbit hole. .. and i still have my big valve head and 34mm tb just sort of sitting around.. just. in. case.

not to disparage HR's page... but you need to verify your ecm looks like this (the one on the left) to use the controller they have listed. IF you do, you're in luck. Mine doesn't, and has the ecm to the right in it as i would image most (at least north american models) do.. as of yet i haven't seen a controller with this interface. .02

For performance records. I work with DHM and he tried so very hard to access the ecu or have another ecu work on it but he had no luck. Also tried 2022 grom a-racer but it idled very high. Looks like the main problem is he cant get into the TPS. says some pins have changed or are different from 2022 grom USA version and Thailand version

yeah and therein lies the rub. I currently run the efie to fool the ecm into running a different afr, and the cam and opened exhaust so far work well with that, no issues for over 800 miles. But im hesitant to go much further w out some sort of controller. I'm figuring i could go to a 143 cyl w my current setup and a bigger injector but that's about it.

I'm still waiting on mine from Beez Deals
@warro has them installed and couldn't get an answer from YSS at the time about how much fluid, so put the same amount back in as what was removed for the install.

It should be the same as stock typically.. wont hurt anything.

It should be the same as stock typically.. wont hurt anything.

In that case, the 2021 Trail125 Service Manual lists 120 ± 2.5 cm³

Hi Folks, fitted my YSS rear shocks yesterday, quite straightforward, thought it prudent to use a small amount of blue loctight on the shock fasteners, also a touch of nickelslip on the exhaust nuts, left the shocks as factory and went out for a spin, road near me is particularly undulating and the difference is night and day, so will tweek the rebound and they will be perfect. next, when time permits will be the YSS front fork internals, ill keep you posted.

 

[Bigman]

here you go...

Did you purchase them from abroad?

 

[Bigman]

they are for sale direct from YSS in Thailand, (ebay) however i bought this set from a guy in the UK who had purchased them and didn't take delivery of the bike, so i had them
