* Any * pipe on bike = must be replaced within 2-4yrs max.
Rubber rots inside too. And gums up parts. Stock lines have tiny holes (slower flow)
Braided fuel and air lines last 10 years , and they run colder (meaning heat resistant) so your fuel doesnt turn gassy on a hot day.
Big holes flow more air and fuel. So your carbs get fuel quicker , big vacuum lines help your pump flow fuel better (it works like a pulse)
So more air in the vacuum system helps.
Giant filters (a good one!) Hold more clean fuel as a mini reserve plus your carb has less dirt going to it. Cant trust every Petrol station out there.
So yes air and fuel lines help. Any extra info is at /shop/ page or search *fuel* in the search bar ^ for a diagram . Pictures will reveal the differences.
Next up. Stock jets are crap. I’ll leave it at that lol.
Bigger jets = slight torque boost, rear engine is COLDER since petrolium has cooling effect.
To understand or how to swap carb jetting Search *Carb* ^
There is a lot that can be done on these machines, but one warning. They hate *china* copy parts! Eg. Cheap £1 lines. 😉
For anything else (tune wise), copy this link or tap below
It saves me rewritting as i get asked often but i am amending the list above as i have done a lot more since then.
Will be finding time to make a proper 101 Book for all things GT125R tuning with probably 3 pages but should be enough to allow people to do things without paying mechanics robbery prices.
Also i have uploaded as many service manuals in forum as (125/250 = same frame) so books also contain a lot of maintenance info etc…
Ofcourse, if try everything I said in the previous replies , your bike WILL run better!
