Yamaha Raptor 700R Piston Install 2 of 3

Watch in high quality! This is a video of me installing a 11:1 JE piston. This is not a how to video, this is just how I did it. Its my first piston install. I had a lot of help from the awesome people over at ModdedRaptor.com. I also studied my service manual big time, and used the web as a source of information.
If youre watching this because youre thinking about switching out your piston, do it! The power feels so good.

Does the engine have to be in any special position? IE: TDC, etc... Did you have to do any kind of 'break in' after installing the piston?

[maxwellsteel]

@Blackman691 TDC, Yes. I just rode mine like normal, so really no brake in.

Take the timing chain and pull it up and over the tensioner guide and put a rubberband on it to hold it in place. This way you wont have to worry about slippin it through seperately. You can use a 4" hoseclamp to compress the rings so you can just slip the cylinder down and not fight with starting the rings.

Good advice from a professional, thanks Bo!

Amazing video. I'm also from the moddedraptor forums and its the best forums i've been on.

Get a dyno vid up with the new piston.

@gottagofast12 It was just motor oil.

Thanks for checking out the video!

[gottagofast12]

what was the stuff you were you rubing inside the cylinder, and then you rubbed something on the bolts too. Was that just motor oil?

[MaxSteelATV]

@doobyboy21 Yeah stock cyl, got it from tqsatv.com

[doobyboy21]

Is this the stock 11:1 bore piston???

[doobyboy21]

This is your stock cylinder right ? Where did you buy this piston ? I know it's JE but what is it's name?? This is the 102mm version ?

Excellent video Max. Found this very imformative. The only thing I would suggest to anyone attempting this same procedure would be to not use the needle nosed pliers to put the wrist clip in. It's possible to distort the clip unless you're really good with the pliers. An easier way is to lay the clip in the groove and use the little opening to get a small screw driver on it and pop it in. Cheers Man.

exactly the same
