65.97mm is the stock piston width for an 04-09

@@motoshack1031 Thank you!

The filter is supposed to be oiled yes 👍

If you are talking about oil being in air box, that's a whole diff story, and you likely overfilled it with oil. If that's the case, I'd get the oil to where it should be before you blow out rings and have an oil chugging freight train👍

@@Atc250sx Ya so it did over flow and i blew it up but its all good now. It only took 2000 bucks for a rebuild 😑

@@quadhooligans8833 only if I was 3 months quicker to reply

@@Atc250sx haha ya its ok man

It isn’t my ATV it was a friends so I was only doing what was deemed necessary, it was pressure washed later on however. 👍

@@motoshack1031 just my ocd kicking in, lol. Great vid though

That’s great to hear and yeah the 3 stone hone has worked great for me on many engines!

@@motoshack1031 How is the Namura piston holding up? I ended up getting that yellow Z250 cheap. Top end is a mess...jug goes to the machine shop this weekend. I can get an O.E. Suzuki piston for about the same price as Namura....

@@tinygaragepowersports0122 I prefer the Namura’s over the stock ones, I have run them in many many machines with zero issues, i currently have an LTZ400 with a 434cc big bore kit with a 12.3:1 compression setup and that is using a Namura piston too, it’s been flawless! 👍

@@motoshack1031 Thanks so much for the quick replies. Good to know the Namura is ok...I read a lot of good AND bad reviews. We are just building this one back to stock to bum around some property and whatnot. Looking for all the missing parts, and giving it the maintenance it never had.

@@tinygaragepowersports0122 sure no worries, just make sure your ring gaps are within spec anything too tight is gonna cause issues and make sure the rings are clocked correctly no overlapping gaps etc and you should be gold

Yeah it’s a vacuum line for the factory vacuum petcock, most people ditch the vacuum petcocks, this one included, they didn’t work all that great hence why people got rid of them and blocked off the vacuum port on the carb!

It’s from a 1982 Yamaha XJ650 Seca Turbo, that was the donor vehicle for the engine swap!

Hi it’s as follows: IN 0.03-0.08mm (0.001-0.003 IN) EX 0.08-0.13mm (0.003-0.005 IN)

I think they make a smaller one for kids, this one and the LTZ400 which I have owned in the past they also made an LTR450 which was the fastest one they made

@@motoshack1031 I mean to replace the tires I need the measurements

Not currently, I have a 650cc 4 cylinder turbo Side by side in the works

It shouldn’t matter as you can spin the motor over after the fact and line up the TDC marks on the flywheel, even if you get it to TDC it will likely move around when taking the piston off etc so I usually don’t bother with the timing stuff until the head goes back on, hope this helps! ✌️

@@motoshack1031 this video has helped out a lot, picked up a 05 ltz 250 for pennies that was seized up from condinstation due to carb being left off. Got it running and driving but its smoking like yours was. Trying to find all the torque specs and valve adjustment specs as well. Thank you🤘👌💪

Thanks bro

Yeah the break in was done off camera, when I was done with the break in I then picked up filming again, I should have made that clearer in the video tbh!

I would make a part 3 but it’s been running good and has no more issues so there would be nothing huge to report on! 😀

Not too sure other than I know it is a Yoshimura slip on, the header pipe is stock I believe however 👍

I have the exact same Quad but mine was modified from the previous owners. I have the exact same exhaust but I don't think it was stock from what I was told and I have dyno jets in mine as well. I changed the graphics and had it painted. It's a 2004

I bought mine on eBay

Thanks for the comment I really appreciate that, I’m glad you liked the video, I’m gonna hopefully make more soon! 👍

@@motoshack1031 I literally was expecting you to have over 100k subs but then I seen you are just getting started. I’m looking at an Ozark 250 rebuild here soon. Your video gave me a good idea of what’s involved. Thanks again.

@@thewordexaminedministries6206 I'm glad it was of use to you, if you need any help feel free to comment with any questions you might have, best of luck on the Ozark rebuild!

Hi there 😄
