Fully Built 3mm Stroker Yamaha Blaster TOP SPEED RUN! Wheelies at the Basket!

Didn't go as fast as it should because it has a different sprocket on the rear axle. This one came with 3 and it was race ready set for the track! Still went pretty fast not like the Yerf Dog! Still I love the $200 Blaster! 10:00 Top Speed Runs.

I did full port n polish on my daughter's Yamaha blaster installed a 10.3:1 piston plus put the tallest sprocket up front and smaller out back plus it has 23x7 tires up front and 22 inch tall tires out Back, also used a 34mm intake and 34mm mikuni carb plus tapped for oil injection, it will smoke a Polaris scrambler 400 2-stroke 4x4 in a drag race for two high line pole lengths, it will top out at 72mph. Keep up the good work. If in North west mn, come for a drag race. 😉

Mine has stock clutch so it slips some, thats all it needs. Even has carbon fiber reeds, all the port holes and skirting trim. Plus it has one of a few flywheel coil adjustments for retarding and advancement. I got it all in a tote in parts and had to throw like $400 OEM parts into the tranny but its fun for sure! Nice build you have buddy!

@@kartguy not my atv, it's my daughter's she loves riding 2-stroke. Myself built a yamaha raptor 770cc, I installed a plus 5mm stroker crankshaft efi controller. 105.5mm cylinder and piston plus 3mm intake valves and plus 2mm exhaust valves, 11:1 compression piston freed up the intake and exhaust plus it's geared to the moon. I can pull it up at 70mph then shift into 5th and it's just stupid. Enjoy riding myself. Keep up the videos 😉

[@georgemiranda-nz2fd]

The pipe is the only thing and the gearing holding this beast from close to doing 80 mph. But all in all sweet ride. Want to build a blaster with your same mods but with a CPI pipe. Do you have the triple exhaust ports done to the jug and the boost ports on the intake side ?

[@kartguy]

All pipes are good but yeah you will love it brother! Sorry it hid your comment in spam IDK why sorry. I have the FMF fatty and Powercore 2 they are pretty good. Yeah it has all the porting and the holes drilled buddy :D Here I show the difference between a stock adn ported jug :D kzbin.info/www/bejne/p4fJdYaLZailmZo

Sounds crispy!!!

[@kartguy]

Thanks!

[@austinhenderson4531]

Mine goes infinty mph

[@kartguy]

Hell yeah!

[@robotabot3]

Is this bored over to 72mm? Also, I have an engine the exact same displacement if it's bored to 72mm with that 3mm stroker crank. I want to port it out and put a 32-35mm carb with new piping and also do a stroker big bore kit a lot later in the future, but I'm not sure if I should. Currently it goes about 50-55 stock, but it's also an automatic. I'm wondering if you have any suggestions about that?

[@kartguy]

Sorry at christmas party try to write again later but yeah I run a 34mm Keihin with porting aned everything. I bought it like this but in a box in all pieces even the tranny for $200 kzbin.info/www/bejne/pX3ceWCNh8ZmgLM

[@kartguy]

I'll try to remember when home to write again buddy!

[@robotabot3]

@@kartguy Damn that's sweet, I'm shocked you got it for $200 even in boxes. Good blasters in my area run for around $1500, most aren't strokers or big bores either. Awesome build though, definitely worth putting it together, even for me if I paid $1000 out front it'd be worth it to put back together.

[@Extrabullets.3nt]

Any words of advice in finishing a build with a 3mm stroker just waiting for my top engine bolts to come in

[@kartguy]

Not really buddy pretty straight forward build, thats why I love Blasters!!!!! For real, but any questions let me know on here and I'll help you out best I can buddy! Hope you get them soon and get to riding!

[@mrstackracks1189]

@@kartguy do u know if not haveing reed stoppers on valves will cause starting problems?

[@kartguy]

@@mrstackracks1189 Yeah I'm not 100% sure but I would think it would cause it to be rougher to start at the least, so could be in my opinion. Sorry hope I'm helpful.

@@kartguy thanks

[@andrewkent1422]

Stop shifting so fast

[@michaelangelod5008]

Really cool did you ever see what sprocket size you have also only guy on KZbin showing a moded blaster going this fast with speed gauge also would be cool of you put street tires and look at gearing and see if you could do 70mph also completely stock everything they go 55mph you doing 9mph faster is impressive

[@kartguy]

Thanks no I've been working on so many things at once I'll try tomorrow I just fueled it up to ride it some more this month. Yeah I'll have to check all that even tire size because I know everything was changed on it. Thanks again buddy!

[@michaelangelod5008]

@@kartguy thank you with what it's geared at do you think you hit top speed to fast or is it just right with how you ride

[@kartguy]

@@michaelangelod5008 I think its just perfect actually. I probably let out little earlier too watching that back. Thinking of trying agin in next couple days over next road on this strip where I did my Kart at beggining of this video first like 10 passes over cam love that lol kzbin.info/www/bejne/baCcmXugo55re5I

[@JoeMama-gs2fw]

What upgrade did you get on it? I’m trying to upgrade mine because it’s bone stock

[@kartguy]

Its got 34mm Keihin Carb, Carbon Fiber Reeds in the V-Force 4 Reed Valve System, custom aluminum air box, the FMF pipes, the 240cc piston and jug, also 3mm stroker crank and all the porting done. I bought it like this in pieces for $200!! Heres what it looked like in pieces! kzbin.info/www/bejne/pX3ceWCNh8ZmgLM

[@devrider2816]

are your sprocket stock?

[@kartguy]

I don't believe so I bought this in pieces and got 4 different size rear sprockets. I think just guessing this is a 53 tooth I will look for sure and that might be the stock as well, I just know it came with 4 different sizes. Let ya know soon. Video of how I got it. kzbin.info/www/bejne/pX3ceWCNh8ZmgLM

[@TheDelbay]

This is nowhere close to a ''fully built'' blaster ... Its not bad, but I wouldnt call it a ''Fully built'' blaster

[@kartguy]

Well my friend it has a 3mm stroker crank, 72mm piston biggest you can get, 34mm Keihin, with the custom aluminum air box you have to have, flywheel with stator that can advance or retard timing, fmf fatty with power core 2, carbon fiber reeds with vforce cage, ported jug with holes milled down head, has a billet clutch boss and basket and just upgraded the clutch. Thanks but it is fully built makes 38 horse when I got it had the sheet. I didn't build this bought it in tote go back to video where it was laying on table in parts and you will see most of the parts. So I do call it fully built.

[@kartguy]

Let me know what else can be done, and if we are talking body as well it's even got 6 inch front extenders to make front 6 inches wider, sti rims and hole shit tires. Upgraded coil and few other things. Let me know what else can be done to engine because there's nothing left buddy.

[@kartguy]

When i got it, you can see some of parts except for i did replace the carbon fiber reeds and the billet clutch boss and basket and upgraded clutch. kzbin.info/www/bejne/pX3ceWCNh8ZmgLM

[@kartguy]

Thanks for telling me it was not bad bud, not bad at all for $200

[@kartguy]

The fact that you said no where close to fully built has me baffled what else can you do I mean there is literally no bigger piston than 72mm and 73 bore on jug which is what I got vitos piston even. Carbon fiber reeds can't get better, the exhaust between Tomey and FMF is a throw up to whos betters but I got FMF, got the best carb, the airbox is over $300 on ebay, got the 3mm crank for more compression along with milled head. I can advance and retard my timing with custom stator which I haven't seen anyone else with same one. Like I said idk whatbelse I can do but maybe you didn't see that was all done to it but it is.
