Hey, how many consecutive minutes can you run the engine before you have to shut it down and allow it to cool off?

demonseed

My answer would be hour and hours and more hours . Check your plug (to make sure your not running to lean)white plug ='s lean dark plug='s rich, and keep up with the oil changes and it should'nt be an issue .

Freddie

That makes no sense. You're telling me that I can keep the engine running for a few "hours" straight without shutting it down to cool?

demonseed

How long do you ride for , before you shut it off ?

I've ran my crf50 for over 4 hours without shutting it off, in 90f+ weather

stage 3 88 kit from honda tb

If your motor is stock it could probably run for days without ever overheating

ya a stock 50 should be able to go for a pretty long maybe a couple hours time with no problems at all.

zbbt

the answer is as long as you want. your stock motor will run all day in any weather.

Freddie

So, if I ran the engine for an hour straight, I'm not going to score the piston, cylinder and disrupt the valve train?

When using to the max, Id say one moto about 10minutes. I use an oil cooler. Still gets warm so I stop by the pits to put some ice on my crank case and my cooler, then its back to the track.

When Im at the trails, my bike can endure about 1:30 straight. At the track, its gonna be only 10-20 minutes during practice. Races, 1moto at a time. It all comes down to what engine you're running and how efficiently it cools off (weather, oilcooler, lubes, fuel, jetting, and riding style are factors)

demonseed

Now that makes no sense .

this is a ttr 50 were talking about. even ridden to the max all day long will not overheat it. this is an issue that doesnt need concern.

Freddie

I'm used to high maintenence race bikes that are good for a 20 minute heat, 20 minute main, etc. So, when someone says that I (190 pounds) can putter around for a few hours straight on a 50cc air-cooled engine that was meant to lug around a 45 pound kid, it's a bit surprising.

Glad to hear that the TT-R50 can take some abuse though.

Me and my cousin rode some fire roads through the mountains all day when they were bone stock pretty much pinned the whole time and had no problems. On a hot ass cali summer day, too.

On a stock 50, or slightly modded one, they can run all day..

10 minutes??? I ride for at least 45 minutes to a hour non stop about everytime I get mine out...

They are built to get hot, hot to the touch doesn't matter, the engine will be over 200f at full operating temp..

I have LITERALLY ran my crf for over 4 hours non stop.. Not shutting it off ONCE! I let everyone ride it, all my friends.. I'd smash around on it for 10-15 minutes, let a friend hop on it tell I cool down.. Then I'm right back on it ripping it.
I've been on the same 88 kit for over 2 years now.. All I do is change the oil every few months, clean and lube my air filter if I ride a lot of dirt, and ride it.


And hell, same goes for my crf 150f.. Thing will run all day everyday, in 100f weather no problem.


edit: Btw I wont do it anymore because I don't wanna blow my motor.. but I have before ran my 50 at redline for over 2 minute straight, wide open throttle.. And my 150 I have ran at rev limiter for over 30 seconds lol..
Not that I'd recommend it, but they took it fine, and keep on chuggin along


As a matter of fact, my friend Trizzbizzle (forum member here), ran his crf50 with a 88 kit, with 2-3 tablespoons of oil, and ran it tell it overheated and siezed the piston! He let it cool off, it unlocked, he rode it again tell it seized! He let it cool off, ran it AGAIN tell it seized! Then he drained the oil, and only like a couple tablespoons came out.. He filled it back up, and now over a year later, rides it all the time! Not saying that was good, I'm sure it caused some compression loss. But just goes to show, these bikes are TOUGH

ya race bikes are TOTALLY different
these trail bikes, produce such little power, and are just built to run and last.

My 150f for example, I guarantee if I wanted, I could ride that thing 10 years on the stock piston/rings/headgasket no problem. Hell I let EVERYONe ride my 150 and 50.. All my friends... In the summer, both my 150 and 50 see at least 20-30 hours of riding a week minimum.. Sometimes a lot more... Hell for all I know, some of my friends could be ripping my 150 and 50 right now, I leave them both at my friends with some land, and let everyone use them haha'

I guarantee my 50 has at least 400 hours on it.. prolly more like 500-600

Thats one reason I don't care for race bikes.. I'll go and put 20-30 hours on a bike in a week.. I couldn't ever have a race bike that 'should' be rebuilt every 20-30 hours

hooper

I think what everyone is saying is that they are bullet proof. Go ride.

tt-r420

Amen!

analogrepresent

Hmmm... Bullet-proof now thats a test i gotta try
