Was wondering when you guys are gonna have a bottom end rebuild video? I have already rebuilt my top end from watching you guys video's! I learned alot from you guys and I plan on rebuilding my old engine completely. No transmission work if it's not needed
Thank you sir! I bought a brand new OEM cylinder, piston, and rings for my YFZ450 and they don't even tell you which ring is the top or the 2nd! Both are marked exactly the same! Thanks again for clearing that up for me ... much appreciated!
How come you didn’t check the ring gap? Also, why does Yamaha ask for the harder chrome ring as the second ring whereas my raptor manual said for it to the top ring?
Most top end kits come with the rings already gapped and for 2 most of the manuals give out faulty instructions everyone has come to find that out over the years
Hi good video:-) I have the same ATV some day the wheels blocked but it seems like nothing broke in the motor but I could not crank it there was to much compression. When I look at my Exhaust cam it seems like the tootwheel is turned on the axle when I time the motor the last lobe is more up then before have you seen that before? best regards Michael
Anti seize on a spark plug? That goes against every spark plug manufacturer's recommendations and is also not recommended in the Yamaha service manual.
So how long did it actually take to get the cylinder on the piston? I see looks edited and it is never that easy. It would be nice to see it all but for time wise I understand
shavings in my oil filter so I disassembled the top end and saw that my crank is stiff so I will replace that and I was wondering if I should replace my oil pump too it’s a 2007 yfz450 and it has that oil squirt thing
If you use a wiseco piston the two top rings swap im guessing because i couldn't fit the dark gray one in the top slot. Anyone else have that issue also???

You make it look so easy, I’m gonna give my engine overall
Keep them great videos coming👍🏽
The best video in the world! Thank you!
Did I miss the part where valve lash is checked?? Or is that another charge so it wasn't done for a "top end" service??
Thanks for the video!!

Never seen it before, but it sounds like a new cam is in order.

Your videos make me wanna buy parts from y'all.
What about a Yfz450 bottom end rebuild
So how long did it actually take to get the cylinder on the piston? I see looks edited and it is never that easy. It would be nice to see it all but for time wise I understand
It varies a bit by how easy everything goes together, it really doesn't take that long though. I don't think we timed it. Maybe 30 - 45 minutes?
Hello can u help me with rings position of Honda crf250r 2006 thanks
shavings in my oil filter so I disassembled the top end and saw that my crank is stiff so I will replace that and I was wondering if I should replace my oil pump too it’s a 2007 yfz450 and it has that oil squirt thing
Yess or just flush it out really good
Is it supposed to be 14 pins in between the two top dots??
If you use a wiseco piston the two top rings swap im guessing because i couldn't fit the dark gray one in the top slot. Anyone else have that issue also???
Why no mention of checking of ring gap?
How do you tell the difference between compression stroke and the decompression stroke?
Your cam lobe position.
What size is the honing tool.
Well. I installed my piston rings all wrong. It is still running fine though.
