I Blew Up An Avenger 85 Motorized Bicycle Engine For Top Speed Runs

- To be honest I just didn't care to own another saw build. I was wondering what the kit could do under the most ridiculous possible conditions to get a top speed run out of it. So I blew one up trying LOL Engine ran 1 breakin tank of gas. Stock top speed run. And 2 Top speed modified runs before it when supercritical! I hope you enjoy!

This was a really cool test ride! pushing it to the limits is all about the fun of it for sure! The best part is it didn't lock up the rear tire at that speed! If it's not your favorite motor then it was worth it in my opinion. I love the content my friend, Keep up the adventures.👍
@@DirectCurrent4u I have another one 😆. Just been so hot! 🥵 Like 100f here in South Carolina for July .
@@BuildBreakFix Thats really awesome! You got me thinking about building one myself. Living in New Mexico I can relate to the 100 degree heat but we have like 0 humidity. Looking forward to your next video!👍
Are you meaning to tell me they made an engine that spins almost 12k with stock 80cc rod bearings? If so that’s wild!!
lasted 2x 11 second pulls anyways lol! engine is completely blown up at the end of the second run. you can hear it explode!
Apparently Not..LoL.
@@BuildBreakFix Thank you for sharing bro I appreciate you🚴🏼♂️💨💨
In a way worth it, awesome man.
Was completely worth it 😆
As long as you imput the actual measured rolling distance of your tire there accurate. Need a few pieces a tape on your floor measured one full revolution I referenced the valve stem.
Hey! Was just at your live. Why did you mute me 😔
Yes. Cheap Chinese Speedo. Says can be off + or - 3 mph. For a 26" wheel. But it did concur with cell phone mph listed so it was close.
@@BuildBreakFix I 100% would not mute or block you
@@BuildBreakFix crap man how do I check my settings 100% your allways welcome to comment on my live. It was kinda good live somehow got to talk to guys from Egypt and India
@2strokecarbtuningportingin187 It said (user is on mute mode) I stopped in to say hi. Couldn't enter live chat. Maybe just glitch then.
Can't wait for the build good stuff
It's fun! If you like to tinker! 😜
Damn BFB that was fast for that engine..I had no idea 😂
Ported the hell out of it lol. Chamber pipes it with reed Valve 15x15mn windowed position
That song "Push It To The Limit" from Scarface should have been playing on ride #2 😂
😂🤣😂🤣
You said 10300rpm, 10t front, 22t rear, 26 in wheel? Your math is off. Thats 88mph . With your speed at 66mph you are pulling 7700rpm..
No dought its off and that clutch was smoking after. It was slipping like hell as it blew up. Just a stock clutch. Wasn't investigating much time in another saw build. "It's in the description". But yeah if it hooked up solid @ 1:8.2 and 1:1.2 ratios comes out to 87.6 actually on 12.6rotations per 1mph for the wheels on the bike. 👍. I think it could of got there is wrist pin crank bearing made id few 100 more yards. Or may of been at its limits all it has to give.
I have a 100cc engine with a 49 mm bore and 40.2 mm stroke with an AF80 connecting rod and high hole piston I had two base gaskets on it and I replaced it with thin one but now I'm only using half of my exhaust port with a 32 tooth sprocket and I'm only pulling 30mph with heavy four-stroking at wide open throttle, if I sent a video and pictures of the motor would you have any information as to how I could resolve said issue, I'll even cash app a few dollars for your time
@ericpedigo685 you know 40mm x 49 isn't 100cc right
@@ericpedigo685 4 stroking is rich jetting. Need to jet down.
@@ericpedigo685 and 32t is way to small
Do u know what went first? I suspect the lower con rod bearing?
Neither con rod breaking existed after that ride
That's awesome fast brother you want to go faster get a motorcycle lol you know I just watched a video you put out 1 yr ago about the importance of properly breaking in a engine and you took it apart and showed the piston all scorched and said this was no good for new engines now you know what happened to your avenger 85 to hard to soon same thing they were doing to the phantom 85 cause I have a phantom version 2 with around 2000 miles on her running great cause your only sapossod to run a 2 stroke 90% of its full power at least that's what my Suzuki mechanic used to tell me that back in the 70es I Googled it and it holds true today as well says they start running to lean thanks for the experiment ride safe
I blew it up on purpose to be honest 😆. I just wanted to see how long one really would last. Didn't think half the claims where true. It does do 66mph that I can confirm 😂 for 24 seconds
@@BuildBreakFixGood engine durability test 👍 😂 It would have been cool to also see stock cyl head temps with a guage. To see if high temps played any role. Next video could be engine teardown to look for scoring on exhaust side from overheating.
@@BuildBreakFixall in the name of science, very impressive thanks for your sacrifice…
Always wanted to floor one of these. See what ya can get out of it before insides come out of it 😆
@@BuildBreakFix it has potential with the right upgrades
Would you say these are reliable after this ? If sticking to a 36t sprocket
Stick to 36t . Keep it mostly 3/4 throttle and the thing will last for a long time. My only suggestion is to replace the wrist pin bearing with Ms380 or Ms 460 bearing like most suggest. One provided is very side play. Other then that seems legitly Rick solid.
Heck yeah. You cant push the limits without pushing past them every once in a while. I wonder if it would actually have enough torque to use that 22 tooth if you got a beefier clutch on that thing (probably not).
I did! That was 22t. Green pads 3 springs, 800lb of springs on saf clutch!
This is what shift kits are for :P
Do you a patreon? Can i pay you to advise me? Lol
I actually never set any of that stuff up on my channel. I'm 100% non profit channel. I donate to charities what I make off of UA-cam 😜👍
👍

Damn, what pipe - did you have? Lol
Mz65 clone
@@BuildBreakFix id imagine that you had to chop and weld a header.
There's some talk about the pipe from Gomax. But there was a guy saying that it didn't fit. He was using the CNC mount and I had said, why are you using the CNC mount? Because it looked to me that he could just mount the Avenger right to the frame and it would seem that it would fit
Anyways he didn't get back with me, so idk...
@KB_Joys all I did was cut off saw the 80cc type header off and cut a square steel plate with 3 holes in it and welded it on. One for the port and 2 bolt holes with a step bit. Nothing fancy just functional
@@BuildBreakFix I had a thought something like that.
Because the muffler comes off.
I still have a jog pipe that I haven't used, was thinking maybe to try to rig it up like the expansion chamber pipes that have the loop around the frame, then go up to the side.
Further reading someone said that id need a reed to gain all benefits.
Might just stick with the original muffler, but I still have a jog pipe, never used.
It was running....and runni...and Boom...whine,screech...Seize... I wonder. Will Gumout help??..LOL....
Glad you're smiling too.
I knew it would explode 😆. Was for science 😂
That is some serious speed 🤠 thanks for the entertaining an educational video
Was a blast to try once lol
66 mph is fast no lie about that one
Why are you trying to kill yourself with Speed?!
That poor motor you ruined it 😭
Let's face it these motors ARE just not ment for all out top end speed runs,, they disintegrate..
But if you run them at mid rpm, they last
Bottom line is red line is 6500rpms and lower. This engine blew up 10k in 2 x 12 second pulls 😂. Yeah if you keep it mid way throttle few fun rips it will last very long time.
I had an open transfer 80cc that I ran wide open throttle with a 36 tooth sprocket on 26-in wheels at 37 mph for about a year it was the cheapest one they sold on wish for $120 as a kit that thing had a tendency to snap rims as well All I did was open the exhaust at a carburetor and a redneck ram air intake to fight the vacuum behind the motor
Holy Mary, mother of your gods... 😮😮😮😮😮😮😮 the Avenger 85 in the hands of a master 🙌.... kinda scary 😅😅😅😂😂😂😂😂🎉🎉🎉🎉🎉 thanks for sharing 👍 😀 😄
Lol blew the guts out of that engine. But damnit we hit 66 mph for 12 seconds😆
@BuildBreakFix oh dip! Hahaha, well, you have said 1000 times that the bearings are not meant for those RPMs hahaa 😆 😜 worth it!!!! X 100!!
So 32 tooth and under 7k rpm
Already did that! 47 mph! Stock out of the box.
Last video speed runs where stock*
@@BuildBreakFix you think you could hit 50mph with a stock motor but upgraded exhaust
Damn that's stupid fast for a bicycle 🚲 .
Ride it like you stole it! 😂
i believe "bicycle tires" are designed to hit 60 mph without coming off.
maybe it good that the motor died instead of you!
E bike rated wheels and tires. 65mph. So yeah we are for sure on the edge.
😲
💪😉
@@BuildBreakFix 65 mph. Scary fast on a rigid bicycle, lol crazy azz 😂
