Rebuild Your Yamaha Blaster 200! | www.rockymountainatvmc.com/Sa...
Whether it's because of excessive noise or just wanting to refresh your engine for the riding season, rebuilding your top end is a great way to get familiar with your ATV and prevent more catastrophic failures in the future. Knowing how to do the job correctly will save you tons of time and money compared to taking it to a shop as well. In this video, Charles shows how to rebuild the top end on a Yamaha Blaster 200.

KZbin tutorials are a blessing. When I was a young teenager my curiosity and determined, but ignorant, "I can do it myself" attitude had me learn all of this the hard way - by trial and error - on my Blaster. Good times. Great upload BTW. My Blaster still runs great, but I couldn't stop watching due to nostalgic reminiscing; "Dad!!! I need your help again. It's the last time - I swear!" Lol

Great post man. I had a blaster when I was 15, back in 2003, and just like you I learned the hard way on everything as I tried fixing things myself. Every young man has that curiosity in him I think. Quads are a great intro to the world of mechanics.

[@Erix7810]

That blaster is in crazy mint condition.

A+ I've never done ANY engine work on anything in my life, so thank you for this video Thanks to this video if one of the 2 Blasters I will be buying used soon needs the top-end rebuilt, I could easily do it, thanks to your video!!! THANK YOU!!!

Compression is key! The lame 6.6:1 Stock compression is ok for beginners, as those advanced, modding with a port n polish along with high compression, and bigger air intake and carb, are the ticket along with changing out the sprockets to different sizes, taller up front and smaller out back. My daughter's Yamaha blaster does a little over 70mph and it will eat my brother's 400 Polaris scrambler in a drag race. Don't fall short on running good 2-stroke oil, every one has there own they love. I like my amsoil for oil injection, watch farm project it actually runs over 20 degrees cooler than other synthetic 2-stroke oils

[@sploofy4878]

no way it does 70

GPS on my cell said otherwise...I'll put money down on it, and like I said it's geared up on front sprocket. Down on back sprocket. 22" tall rear tires. Bring it on....

[@tiberiuculda171]

great video buddy but i do have to correct you dont ever use a ball hone on a 2 stroke cylinder us the straight stone type .. ball hone will damage ports

[@dentalnovember]

Blaster=Two stroke goodness!

[@gabepim3496]

Rocky I wouldn't use china ..bad experience with them and never again ughh whyyy

[@Sean85Laney]

Oh boy!!!

[@titletownclowns1545]

Great video as many of these machines don't get the top ends replaced as needed and showing how easy it can be to restore power to the little beasts. Make sure the ports chamfered free of burrs from machining and it should be mentioned if the rings do need filing to remove the burrs on the end gaps. I would use the correct tool for expanding the rings on the piston and the "if you don't have the tool" as shown, gotta upsell to the customer. Pops

[@electricianslife1984]

What’s the cost of doing this yourself vs. having someone do it for you?

[@skyroboss]

Does it matter which side of the cylinder nut washers face down? Theres a flat and a rounded side.

[@janeali1174]

Sir i have two stroke cylinder i want to increase its rpm power please help me how i can increase the speed from its ports. Please help me tell me sir

[@the_ltz_guymaster7912]

I’d like to see a 97cr250 there so many blaster videos and none about the 97 cr 250 no shops will touch them

[@chriscortum7743]

Where does the oil injection line go into? Cylinder -intake boot

[@RubberSalt]

Those green base gaskets tend to leak and blow out. Those china pistons tend to grenade. The cheap wrist pin is the worst part of all. They can't take the load of the blaster... I'm only 3 minutes in

[@Donnavinn]

When my blaster blew up on the side of the tip of the piston chiped off and dug into my boar dose anyone know why?

[@Deepwater_hydro]

Please answer this question. Why does your Reed boot have a blocked hole at the top but mine is open???

[@pollux2825]

it’s blocked to prevent an air leak. If yours is open you got a huge air leak

[@julianmontes8544]

Do you know how to fix a blaster that won’t shift passed 3rd gear?

[@rmatvmc]

It's hard to say exactly what the cause could be but it sounds like a transmission inspection and rebuild is what's needed.

[@evil14life]

Great video....BUT there is no way I'd use that cheap china stuff. Those parts fail at a very alarming rate, and are the reason cases for the blaster are getting hard to find and expensive ( once that cheap piston drops the skirt and wedges material between the crank and cases). Ask any engine builder out there (Ken O Connor Racing, Eric Gorr, etc) what they think of these parts, you won't like the answer. I am honestly surprised you guys offer and promote these cheap parts. Boring the oem cylinder and using QUALITY parts ( Quality brand piston kit and gasket set ) will be the best way to keep these machines reliable.

[@bobbymckinney1264]

Put ya a 240 kit with a fatty pipe,and some v force reeds,smaller tires on back make a wheelie machine lol check out time machine channel he's good on these blasters,this was good video showing how bring it back to stock

Right?! haha

seems to be out of stock on your site

[@jonathanoutlaw8925]

Arnt u suppose to glue that gasket down where the bottom end is at and the top???

[@rmatvmc]

No glue necessary. Especially not on the head gasket. Just make sure your gasket surfaces are clean and use new gaskets. -Charles

[@kingken5395]

14:09 low coolant?

[@pollux2825]

Not talking about a blaster engine just an engine in general.

[@matthewedwards6108]

I just bought one and guess what this same top end is what is on it and now im having to have a OEM top end bored and fit for new piston just to put this bike back together. Like its ment to be the Chinese top end was junk and bike was running hot cause of it and would have cost major failure just like a great bike here and a original top end that u just took off to make it so called easy when u could have put the OEM back on it bored to the next size .... if i was the owner and you pulled this 💩 ud be replacing it with the oem or not getting paid knowing the part you put in will not last at all

[@rmatvmc]

The owner of this quad is the one who decided on what piston and cylinder kit to put in. Thanks for checking out the video!

[@pollux2825]

This dude really put fake chinese parts on this quad 🤦🏻 that’s sad
