GY6 50 139QMB Cylinder Big Bore Upgrades
Good Morning folks, today I will address another concern of mine that I have posted on these pages once before a few months back, I have seen many consumers read this info by looking at the stats for info that I will get a little deeper into it.
The GY6 50 Four Stroke scooter engine can be upgraded with cylinders and heads up to 52mm, as far as CC’s are concerned I have rated this at 85cc. Keep in mind that two stroke machines with same size cylinder are rated at 90cc-107cc, the GY6 125 is 52mm also and is rated at 125cc.
The 100cc kits are not 100cc please run from these
The problem that is happening is dealers online who have no shops or experience are selling four stroke big bore kits for GY6 50 engines that simply are deffective. and if they do even start to work they break down and also are junk.

Carb Jets have become one of the best ways to fix a lot of nagging problems on these two stroke and four stroke scooters mainly the low cost ones. What we have found is simply increasing the idle jet to a 45 up from 35 and adding an 80 or 85 main jet does the trick plus adding a dual layer filter from
Stage 6 Dual Layer
UNI or Stage 6 really gets things going for smooth running and easy starting.
Pilot or Idle Jet
Plus it works two ways that help both the two stroke and four stroke models. They restrict these scoots so much when making them simply adding larger jets seems to always help. The dual layer carbs hold the back pressure for gas flow.
Str8 Air Filter
When we get dirty carbs the fist thing we do is replace the idle and take a look at the main jet as well as the plug and always find we can increase the jet sizes with more fuel that way we can add more air without it getting too lean and increase it even more if we can then completely clean carb.
The jets we carry are mainly 5mm and 6mm and work in many two stroke as well as four stroke. The idle jets we have are what comes in all CVT carbs used in four strokes plus out two stroke idle is for the Mikuni style and some mains for Dellorto carbs also. We will offer a lot more for the PWK carbs we offer that we are using and the OKO.
