I run a race cut harness so i actually don’t have the connection for that along with some other stuff i eliminate. As far as the machine goes i don’t think you gain anything w the delete.

Thanks for the video bro really helpful. One thing i need help with, the shim sizes you use for hot cam stage 2 if you have. Or maybe the specs. Thanks in advance brother
@ononewheel74 ай бұрын
So the best thing ti do is grab the hot cams shim kit then just check the valve clearances and adjust accordingly. A good micrometer is a must have and there are websites online that can do the math for you to find the correct shim size.

Awesome video John! One question for you, I have a small drippy oil leak from my rebuilt motor, at one of the bottom end case bolt nearest the brake pedal. In your opinion What could be a temporary solution for this leak as an engine builder without tearing the engine apart to chase a leak? Some sort of rtv? Thanks in advance.
@ononewheel73 сағат бұрын
Thank you. Have you tried just re torquing the case bolts? Is it coming from the case half’s?

Great video! I picked up a 2010 Yfz450r and the engine was in boxes all apart. The buckets that hold the cam shims were all separated. Any idea what the stock shims would be for intake and exhaust?
@ononewheel7Ай бұрын
Thanks man. You would really need to assemble it on a bench then bench shim it to see where it’s at then adjust as needed.

So my 1/4” one is a huskey (home depot) then my 3/8” one is a Kobalt (Lowes) i actually just replaced them both today with a new 3/8” digital one from lowes a kobalt and it goes from 5 ft lbs - 100 ft lbs it was 176.00 which i don’t think is horrible considering it will replace my previous two. I am excited to start using it. Thank you man put a lot of work in this one glad you liked it.

Would you be able to tell me how to verify oil pressure/feed going to the top end on these? I just did a full rebuild and want to make sure as the oil pump looks a bit worn (new one ordered) should I just run it for a minute and check if the cams are soaked popping the cover off?
@ononewheel74 ай бұрын
Remove the valve cover and pull the spark plug wire and turn it over and check for oil coming out on the top end
@ivan535944 ай бұрын
@ononewheel7 should there be alot coming out or just a dribble from the top? I'm not sure if my starter is spinning it fast enough to pump all the way up to the head.
@ononewheel74 ай бұрын
It should be a decent stream of oil
@ivan535944 ай бұрын
@ononewheel7 I guess there's a check bolt on the backside of on the cylinder #8 bolt near the intake boot. Once started it streams out of there pretty good. Thank you again for your videos and replies. Thanks to you I feel like I know these motors in and out now😀

hello, I have a problem with yfz450r. Currently I have sharp camshaft and an hc piston. The engine has no strength to turn, there is too much compression. Valve clearances are 0.20 exhaust and 0.10 intake After blocking the decompressor, it turns the same, and he sees a defect in it. Is it possible that the valve is not extending enough? how to adjust it and is it possible?
@ononewheel74 ай бұрын
You need to double check your timing. You need to set top dead center on the compression stroke this is when the piston is traveling up when turning the engine over by hand counter clockwise. Your cams may be 180 degrees out of time. Check that and let me know.
@QuadGarageATV4 ай бұрын
@@ononewheel7 So here's how: I checked the timing three times and it's OK each time. Turning the engine with a socket wrench is no harder than in other engines. The problem occurs only when trying to start it with the starter - before the TDC it slows down a lot during the compression stroke and as soon as it passes it accelerates and then slows down again. One person suggested setting the valve clearances tighter (0.15 exhaust), (0.05 intake) and setting the decompression clearance, whatever that means.
@ononewheel74 ай бұрын
@QuadGarageATV you can’t really know by turning it over by hand its normally hard as it builds compression. How old is the battery and starter? One or both could be weak. If you have a compression tester you could check compression. And the decompression spring is intact right. I run 14:1 compression and mine starts fine .
@ononewheel74 ай бұрын
I don’t think changing valve clearances will change anything. If you go tighter it will make it harder to start. Looser won’t make too much of a difference except for some valve noise.
@QuadGarageATV4 ай бұрын
@@ononewheel7 Hi! I dealt with the problem of difficult starting and basically the inability to start. It turned out that the error was in the rollers made by the company. The decompressor pin did not extend as much as it should, I put a different exhaust shaft and everything returned to normal. The exhaust shaft went for repairs where they previously wanted money for supposedly adjusting the decompressor clearance lol! Thank you for your willingness to help, sorry for my English but I use a translator :)
