A friend sat on my bike, started the bike and immediately rev it to 6000 rpm twice before I got a chance to stop him. He never being on a bike before so he thought we could do it the same way he does it with cars. I always wait until it hits 120 degrees before riding off or revving the engine.

Could this have caused engine damage...? I started the bike for a few seconds the day after and I could smell oil when I first started it.

Are bike engines that sensitive? is that the reason why we always need to make sure the engine is warm before riding off?

im no mechanic but i know you have to wait for your bike to warm before riding it as you shouldnt rev the bike whilst the choke is still on as it does cause engine wear, however i would have thought damage will only be caused throught constant abuse, u might just smell oil cos your paranoid

It's not good for a bike or a car to rev it up when it is cold. Doing it once shouldn't kill it though. It probably did minimal if any damage to your bike.

I think the jury is still out on this one - I have read that you should start the bike and get moving as soon as possible. Don't redline it until it has warmed up, but don't let it sit and idle just to get the engine warm. You need to put some load on the engine and vary the revs to warm it optimally. Just letting it idle in the garage until it's warmed up can cause blue pipes and damage the engine.

Have you all heard something else?

As for starting the motor and revving it up a couple of times ... if the motor has been properly broken in (you have more than about 1000 miles on it), this should damage anything - I just wouldn't do it too often ... :roll:

Question - Why do you let your friend sit on your bike with the key in the ignition? You're damn lucky he didn't accidentally pop it into gear and send it through a wall!

Good observations, Inspiron.

Right after I got my Bandit, everyone at the FD wanted to sit on it (for some reason). One guy, that I particularly did NOT like, was sitting on it (his turn, I suppose :roll: ), and he said, "Where's the keys?" I patted my pocket and said, "Right here." he puts his hand out, like I'm going ot give them to him. I said, "I don't think so, Timmy." He said, "I ain't gonna' start it."

I said, "Then why would you want the keys?"

<heh heh>

<heh heh>

to take the steering lock off, if it has one dunno what u ride, it prob just said but i didnt look>


as for what inspiration said ur right i do normally slightly fluctuate the reves while it warms up, just dont give it death

 

[themeatmanlandry]

The steering head wasn't locked.

I don't know much about this, but having heard it from 2 motorcycle mechanics: Bike engins are tough little things. I really, really doubt he damaged anything or even put unusual wear.

Thank you for all the replies.

I took the bike out this afternoon for the last time this year.... it's getting too cold and it's time to put it away until next year. It seemed to run fine and I am looking foward to another great riding summer in 2005.

As long as he didn't rev up too high ( close to or at redline ) then you will be fine. With the newer engines coming out these days you can actually put them through a lot of abuse before you notice anything wrong. That being said there is no way that I would let him sit on the bike again. If he really wants to do so that bad, he can go to a dealership and try their bikes out.

If it ran long enough for oil pressure to build, it's fine. If it was so immediate that metal-to-metal contact occured, you took some miles off 'er.

What a jackhole. Shortly after buying the Bandit I stopped at a park to see my brother, who was working with a group of kids. One of the more obnoxious ones walked up and grabbed a hunk of throttle before I knew it was coming - the first week I had the bike. :evil:

 

[jaydog19833]

Hahah I hope its not too bad either. About 3 days after I brought mine home I started it in my narrow shed, and it almost tipped over when I took my hands off the handlebars (the wooder floor buckles under the weight of the bike). In reaction I grabbed the bars again WHOOOO WHOOOOOOOM right on the throttle. haha oopsy.

Inspiron, there's been oodles of debate over the best warm-up practice here in frosty Minnesota. We talk often about that when it's 12 below. Here are my thoughts:

Warming an engine up by easy driving is quickest. It's best practice unless it's witch-tit cold. Then, you should let the engine run for a minute or two to really let the oil get moving and burn moisture out. Otherwise, mild driving warms the engine up more quickly without causing undue wear.

Idling to warm-up will not cause damage, as you indicated, but may allow blackening of the spark plugs, and more soil deposits in the oil. Blue pipes come from overheating since there's no airflow over them while parked. It happens eventually anyway.

I've always been told to crank your bike (cars too) and lety it run for just a short minute or two (depending on outside temp) then ride it to warm it up. I was told this was best because it lets all parts get oil before you take off.

 

[Clint]

If oil isn't flowing within several seconds, you have a mechanical suicide on your hands. The reason you'd wait longer is so that the cylinders have time to warm and expand with the pistons.

I didn't know that. Good info to know. I thought you let an engine warm up to warm the oil, changing the viscosity to a desirable level.

 

[Uncle Bob]

As most have stated here, a minute or so depending on weather is more than enough IF you're enigine is in tune.

Don't want the engine dying as your taking a hard right out of your driveway, can you say Fall down go boom ?.

:shock: :shock: :shock:
Yikes. I know what you are talking about. I started to pull off one time and it puttered a bit. What if I'd been turning out of the neighborhood and entering traffic? :?
