Excellent.

Good video.

Decent video once again Sam, well done. Wish i could do this

This is great content thanks so much.

As an amateur home mechanic and occasional engine builder, I thoroughly enjoy seeing you work through the build - thanks for posting 👍🏻🍻

Very informative as always. I have very basic knowledge of engines and have always had a 636. I hope you don't mind me asking, but when i got a full exhaust system at the dyno center they recommended removing the AIS system (track only bike) and put block off plates. I may be wrong but it seems like the top end of this engine still has the opening for that air system? Am I wrong, can you share some more info? Sorry if this is a dumb question.

@@therealtze Hi, this engine the AIS is blocked off internally 👍

[@therealtze]

@@PalmerPerf_ Aha :) Much appreciated, taking the time to drop a line.

Another great video! Currently working on my ‘16 zx-10 race bike. While the engine is out I’m performing valve clearance check, and now considering maybe putting in a thinner head gasket. (.65mmstock, might consider .55mm)Will I need to buy adjustable cam gears and degree the cams to compensate for the thinner gasket, or am I fine just sticking with the standard timing? I’ve heard mixed opinions online, but value your opinion the highest. Thanks from Canada!

@@Frozenplain204 Standard timing is good 👍

[@Frozenplain204]

@@PalmerPerf_ great thx!

so other than different cams and degreing of the cams, there is no other work for this supersport engine build? weird. because the older 2010 race kit gearbox can fit in this newer zx6 cases. and they have the transmission shafts and gears shimmed so the gears sit closer together so the lever throw will be less. i am really curious about the retrofitting of the older airbox with the top injectors. because the airboxes are the same dimensions.

[@PalmerPerf_]

You must have missed the parts about the super finished gearbox and the ported cylinder head 🤷‍♂️. It also runs an aftermarket slipper clutch. The older model race kit gearboxes would be difficult to find even if we did want to use one, the option would be a Nova Racing gearbox. There are performance gains to be had from running secondary injectors like I mention in the video 😁👍. Thanks for your comments 🙏

[@TheRealBhuado]

@@PalmerPerf_ there is a new race kit for the 2024-2025 bikes. and it mentions that the transmission is interchangeable with the older 2010 transmission. i say this because i saw the part numbers that you use for the crank bearing halves and rods are the standard parts. while the race kit is using different halves that have different coating on them. i am not judging. i am just curious of the different combinations people are building engines on. and i know this is 2019 engine. the top feed injectors would be something i have not seen before retrofitted. cheers.

[@PalmerPerf_]

@TheRealBhuado yes, for the extra expense and availability issues of the race kit bearings we've never really found any benefit over the standard items 👍. Interesting about the new race kit gearbox, again we don't tend to use them as the prices are normally very expensive and availability poor compared to using the Nova Racing gearboxes or super finished standard 👍

[@SeanRidley-g7z]

What year is this engine please?

[@PalmerPerf_]

2019 👍

[@garymorgan628]

Apart from a component failure how long would you expect this engine to last (race use or normal use )?

[@Hondmad]

Approx 2000 race miles on this spec of engine. Not a high compression build so will last longer than a really stressed high comp engine.
