170cc to 184cc Big Bore Kit
and 28mm Carburetor Performance Kit:

  • All aluminum ceramic plated 64mm cylinder with skirt
  • We increased the skirt height and size on the lightweight high compression 64mm piston with rings, pin, & clips to increase reliability and service life (picture is not updated yet showing piston change)
  • Head gasket kit – includes the cylinder head o-ring set and an exhaust gasket.
  • 28mm Performance Carb (125 main/50 pilot)
  • Rear Facing Intake Kit – not forward facing like the KLX110 style (picture is not updated yet showing intake change)
  • Jet kit for varying conditions and exhausts
  • Throttle Cable

If looking for easy bolt on power for the YX/GPX/Zongchen
engines, this big bore and carb
kit is it! Works great with your stock head or our new V2 Race
Head. The kit includes an all aluminum ceramic plated 64mm
cylinder (with skirt) which will increase your engine displacement and power. This
cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction
(increasing power), improves sealing, and provides better heat transfer (runs
and cools down quicker). We top off the bore kit with a 28mm performance carb
kit that is easy to tune and works much better with this setup than your stock
Chinese 26mm carb. Additionally, our head gasket kit also includes a head o-ring set and exhaust gasket so you don’t
have to re-use your old ones or make a trip to your local dealer to get new ones
and spend more money. The new bore kit consists of high quality
parts and requires no machining to the cases – bolt on
and go! This kit is only for the YX/GPX/Zongchen 150cc to 160cc engines with
a a KLX110 type topend. The increase in displacement will depend on your
stock engine size. With this kit:

  • A stock 150cc engine will increase to 170cc
  • A stock 155cc engine will increase to 177cc
  • A stock 160cc engine will increase to 184cc

There are no installation instructions, but if you can replace your
piston, you can install this kit. If you don’t have any experience working on
your engine, we highly recommend having a professional technician install this
kit. The parts are installed in the same manner as
OEM parts.

Great mount / Terrible charge rate
Love the mount. Easy to install and with a small piece of double sided tape under the top edge, it’s very secure… The magnetic mount is strong enough to hold an iPhone max (at least mine). The charging ability is where it falls short *BAD! It will charge but, barely.. If you’re using maps, making calls, etc.. the phone continues to drain at an alarming rate…

Not suitable if you have a silicone case.
I'm waiting for delivery of new phone case, as the silicone one I have on my phone will not hold onto the magnet provided for this holder. Installation was a snap and I love how it looks in my car. Cost seems fair for the product. Fingers crossed that it will work fine once I get a new case.

Charger portion stopped working twice now
Works well until it doesn't. Was excited to get the phone mount off the car vent but I have gone through one replacement already and now I'm past the point to completely return it. Twice now the charging portion has failed. The first one stopped lighting up completely with in about a week and now this one just constantly flashes and no longer charges after another few weeks. I have tried different cords and outlets in my car with no success. The magnet portion however is strong and does hold the phone well.

Perfect for every day use
The Wincar Magnetic Wireless Phone Mount and Charger is a thoughtfully designed accessory tailored for Toyota 4Runner models from 2010 to the present, and it also fits well with other vehicles using a 17mm ball mount base. The package includes a sturdy mount, a 15W magnetic wireless charger, a charging cable, and two steel rings. These steel rings are particularly useful for those who do not own a MagSafe-compatible phone or case, ensuring broader compatibility.  I specifically purchased this charger and holder to use with my existing 17mm ball mount base, which I found challenging to match with most other products—especially for my Lexus GX460. While there are many phone holders on the market, very few offer the dual functionality of both MagSafe mounting and wireless charging in one unit. This all-in-one solution eliminates the need for multiple accessories, but it’s important to note that the charger /mount  require a power connection to operate.  In terms of performance, the Wincar mount and charger deliver impressively. When connected to a reliable USB-C charging source or a USB-C cigarette lighter adapter, the magnetic grip is strong, keeping the phone securely in place even during bumpy rides. The wireless charging is efficient, providing a reasonably fast charge without overheating or lag. The magnetic force is particularly robust, ensuring that the phone remains stable and aligned for optimal charging.  Overall, this mount and charger combination offers a seamless, convenient experience for anyone seeking a reliable phone holder and charger for their vehicle. For my needs, it has proven to be both practical and effective.
