TB 88cc Big Bore kit, Race Head, & 20mm Carb Kit – K0-78 Models

TBparts complete 88cc bore kit, Race Head, and 20mm Performance carb kit. This complete 88cc Race Head Kit will really wake up your stock engine and is comparable in power to the much larger Chinese 124cc engines!!! They are extremely reliable as well! Made to our specifications turning your worn-out stock engine into a high-quality, high-performance engine that makes big power!

Starting with the 88cc 52mm Big Bore kit. Our aluminum steel sleeve cylinder is super lightweight compared to stock and it also helps with heat dissipation. The piston is high compression but safe for 91+ octane pump fuel. The bore kit also includes the top end gasket kit that includes all the gaskets for the job. Next is the race head included in this kit. This is what really sets our kit apart from the competition especially considering the price. When you replace your worn-out, carbon built up stock cylinder head with our new complete bolt on race head you get a ton more performance and power. Better geometry allows for a bigger cam, larger valves, and bigger, better porting. Plus, it is made to our specifications to keep quality in check with OEM standards. This is extremely important when turning big RPMs and making big power. Top that off with the 3mm larger 20mm performance carb kit to feed the new larger displacement engine. This also includes a port match manifold with all the necessary hardware.

Key Features:
  • Lightweight aluminum cylinder with steel sleeve
  • Cast in mounts on cylinder for aftermarket skid plates
  • Oversized cooling fins on cylinder for efficient heat dissipation
  • 52mm high compression piston with rings, pin, & clips
  • Head gasket kit and clutch cover gasket.
  • High performance race camshaft (for the Race Head only)
  • Race Head with larger 25/22mm stainless steel (21-4N material) valves for better flow and increased performance. Also has bigger cooling fins. Includes all necessary parts and comes assembled!
  • 20mm Performance carb assembly. Includes: 20mm carb, port matched intake, heatstop, gaskets, mounting hardware/wrench, long adjustable throttle cable, and an angled dual layer foam air filter.
Fitment:
  • Z50 K0-78 Models

Good value for price
Size: Freo S
Update - returned due to lackluster battery power. It would vacuum on “regular”, and come back to recharge after less than a hour. It’s too bad, because otherwise it was great. This is a pretty good system for the price, especially if you have primarily hardwoods/tile. It’s not great on carpet, and I really need a vacuum with more suction power. It will not remove enough pet hair from my low pile and washable rugs to make the investment worth it. Battery does not last as long as other models I’ve tried. It returns to recharge many times for my 3000 sq ft. I have a multi level house, with multiple thresh holds (home has many additions). I need a vacuum that can save 6 maps. This only saves 3 - which to be fair is typical in this price range. I don’t even know if there is a vacuum that can save 6? WiFi was easy to connect. Not too noisy when running. Seems well-made. Just needs more suction for my needs. Overall this is a decent system for this price point. I need something more powerful so I’ll probably be upgrading.

Not slim
Size: Freo S
Update AGAIN! I have had it 7 months now and it started making a noise like it was stuck on something but theres nothing at all there. Contacted customer service and they said its the brush and lid, so they send a new one. Great. I get it and install it and it makes the noise still contacted customer service again and they said we can send a new brush and lid, i said i just received a new one and its still making that noise. Now they said we will get back to you soon but its been 5 days and nothing. I have contacted them again and still nothing Update. I’ve had this for several months now and theres a few problems beside it being not thin enough to go under furniture. I dont like to set up ‘task’ because its not always convenient at the same time each day so i usually just open app and push start. The problem is that it doesnt do all the rooms even if i have chosen all the rooms it also doesnt self empty unless i go into the app and self empty it. It does sometimes but not always. Now customer service says that i have to set up task, but why?! We should be in control of the robot not the robot of us. Also, you can not send it to a specific spot it missed. If i move my robot over a spot to revacume, it loses its mind and wants to start remapping. I still like that it vacumes well(besides missing here and there) but i do regret getting it. Also it sucks on edges, so i sweep the edges to it vacumes more. Will not keep them in mind for the futre. Received today. Way easier set up to wifi than the coredy. Way quieter too. Its not slim and wont go under my sofas , that was disappointing. It needs at least a 4inch clearance 5 to be safe. Dont recall seeing that in description but i could be wrong . It also doesnt have a way to manually navigate it , either a control or a way from the app. I will try it out since i like the quietness and the sucking power.

Good quality for the price
Size: Freo S, Size: Freo S
NARWAL Freo S — Truly Hands-Free Cleaning! I’ve been using the NARWAL Freo S Robot Vacuum and Mop Combo and I’m genuinely impressed. The 8000Pa suction is incredibly powerful — it picks up dust, crumbs, and even stubborn pet hair with no problem. The mopping function leaves my hard floors looking fresh and streak-free. What I love most is how hands-free it is. The self-emptying base really works — I don’t have to think about it for weeks, and they claim up to 180 days! The LDS navigation is super accurate, and the obstacle avoidance means it never gets stuck.

Not a mop, vacuum only
Size: Freo S
This is really only a vacuum. It is not a mop, at best it could be considered a “dry mop” but that doesn’t really clean floors. Good price, and it vacuums well enough. Doesn’t seem to get stuck nearly as much as my old Shark. I gave 3 stars because half of what the title says it can do is misleading/not true

Budget Vacuum Surprise
Size: Freo S, Size: Freo S
I wasn’t expecting much from a budget robot vacuum, but it really surprised me! I’ve owned a few high-end vacuums in the past, so I was skeptical about how this one would perform, especially given its price. But honestly, it handles my apartment like a pro. The suction power is great enough for my place. It picks up everything—pet hair, dust on both hardwood floors and the rug. The dock is simple to use, and the best part is I don’t have to worry about it too much. Just clean the mop pads every now and then, and that’s about it. The dustbin is large enough that I don’t have to empty it after every cleaning, which is a big time-saver. For someone like me, living alone with little time to clean, the Freo S is perfect. It gets the job done without the extra features of pricier models. If you want a reliable, budget-friendly vacuum, this is a great choice.
