* About quality and texture, So many parts in this kit but the ones to focus on is the NC machined cast aluminium piston, all aluminium ceramic plated cylinder, forged aluminium roller rocker arms and the aluminium super 4 valve head with efficient valve design and NC machined combustion chamber.* About the feeling of use, This 4 valve head and 181cc cylinder kit changes the Grom entirely. There is just so much power down low now and the power keeps going as you rev all the way to 10,000 rpm, it's a beast.* Products to buy together, So many needed but the Dynojet Power Vision 3 is a great product to add to your cart for your timing and fuelling needs to operate the engine with this huge change.* Difficulty of installation, Installation of just this kit is straight forward when following the instructions, be sure to take your time checking the ring gapping at the start and the valve adjustments at the end. The process was completed in 120 minutes with a little difficultly.* Cost performance and comparison with other products, The SP Takegawa 4 valve big bore kits are the most expensive available. You can also take a look at the Endurance 4V 170cc BBK which is cheaper but take a look at the supplied power charts to see which of these 2 kits is best suited to the style of riding you intend to do.* About shipping and packaging, I am happy to wait 8 weeks on average for my parts to arrive in Sydney Australia via Webike's sea freight which comes with tracking and insurance so I know I'm covered in case something was to go wrong but with there outstanding bubble wrapping and boxing there have been no problems.* Any concerns, cautions, or advice when purchasing, As mentioned above you need to purchase a huge amount of parts to install one of these kits and keep the engine running reliably, all available to purchase here on Webike. Use the product reviews to assist in making a decision on your purchase.

1 cam 4 valve head for easy handling and high output!
It also comes with a big throttle body kit to maximize the performance of the Superhead 4V+R head.
■Super Head 4V+R (1 cam, 4 valves)
Two intake / exhaust valves are used each to increase the valve curtain area and achieve high intake / exhaust efficiency.
The original head shape was designed to balance the center plug, valve pinching angle, combustion chamber shape, and port shape to achieve a higher output than the stock head.
The combustion chamber is finished with high accuracy by NC machining.
The highest class of SOHC intake and exhaust efficiency
Valve diameter IN: 25mm x 2 / EX: 21.5mm x 2
Valve Stem Shaft Diameter: 4. 5mm for both IN and EX
The use of unequal pitch valve springs prevents surging at high RPM.
The cylinder head surface is painted black.
Since the inspection breather cover is included, you can release the internal pressure of the engine by purchasing the oil catch tank kit separately.
Inspection Breather Cover and Inspection Cover are machined from aluminum and plated with beautiful chrome.
L. Cylinder head side cover is made of die-cast aluminum with barrel polished finish.

■Camshaft / Cylinder / Piston
auto decompression camshaft
It is possible to start the engine smoothly without putting a burden on the starter.
All aluminum ceramic plated cylinders.
Bore Diameter: 63mm Stroke 57.9mm (Stock)
