Starting the engine at 3K rpm (chock) bad for the engine?

[gsf500RR]

Hello guys

When I start the engine with chock open at maximum (I do this when it's cold for example) the engine start at around 3K to 3.5K rpm. I can then reduce the chock but I'm always risking to stall the engine (bad when it's very cold because the battery can be exhausted).

So I wonder, since the engine is cold, is it bad to start it at 3k RPM and let it that way for 20 secondes (then I would reduce the starter)? Or would it hurt the engine.

Thanks you.

Do you mean the choke?
I always try to keep mine at 3k or less when warming up when really cold or damp. I'll start riding after 10 seconds or s (about the time it really takes to get situated to ride properly.) Then by the first corner or so I reduce the choke as the idle speeds up and get it down to 2k or so for another couple blocks. If going a long distance without stops, I'll just cut the choke because I'm riding at 3k-4k rpm and after 10 or more blocks, it will be warm enough when I have to stop. I think 3k is better on the engine than cold at lower rpm where it chugs and backfires.

Yes I mean chock I am bad with english sorry.


"I think 3k is better on the engine than cold at lower rpm where it chugs and backfires." That's intersting I didn't though about it. Since I have always been told not to high rev on a cold engine I wonder if 3K rpm is really high or not (it's still 3 times more than 1K rpm).

I always start the bike up with full choke, It'll chug at around 1500rpms then start rising as it warms up. I'll keep reducing the choke so the rpm stays around 2000rpm. Usually that only takes about 20 seconds and the choke lever will be at about 1/2-1/4 on. I drive off and then take the choke off after it'll hold 1200rpm without any choke.

My GS500 owners manual says under riding tips-

STARTING THE ENGINE

When engine is cold:
1. Turn the choke lever all the way towards you. Close the throttle completely.

2. Push the electric starter button.

3. Immediately after the engine starts keep the engine speed at 2000 - 3000 rpm by varying the choke lever position.

4. Move the choke lever to the "OFF" position approximately 30 seconds after the engine starts. It may be necessary to use the choke longer than 30 seconds in extremely cold weather.



Hope this helps

Just a thought...or an insight. 90% of wear happens at intial start up of a combustion engine fed and lubricated with oil.

Now that you know that why would you ever let a cold motor of any design rev higher then neccessary to acheive warm up? Always keep RPM's as low as possible using a chock or a choke!

If Suzuki thinks this is good, why are we trying to second guess them? I'll bet they've done more testing of motorcycles than anyone on this forum!

Experince? If you know all then don't ask. I was being helpful as a son of an ASE certified mechanic is all?

I can only see one person asking a question here? The rest of us were giving advice. Seems someone has taken something a little personally?

The problem is I don't really have the choice, sometime if I try to start the engine without the engine it's pretty hard to avoid the stall of the engine (and then I have no more battery if I do that to often). Hence my question, is 3K really bad? I'm sure that if you start the engine giving gas at 6k rpm it's bad but 3K rpm I don't know if it's a lot or not.

If the manual say to stay between 2K and 3K then I guess it must be not that bad.

No worries. It won't wear out.

If you keep it for 75,000 km, maybe there is a very slight difference based on handling choke at startup, but more likely it will be gone from crash damage or you sold it by then.

At least when it starts at 3000 it's flinging oil around, that's how cylinder bores get lubed  
I would then start to get it closer to 2000 as soon as the engine allows then within the same minute try to use as little choke as you can. These things are coldblooded even after jet changes, a 3000+ burst at start up may be the best thing you can do for it?  (oil into the cylinder bores) I think your fine.

Stevo is spot on. Revs around the 2.5k or 3k get the oild pumping around quickly at start up time  - particularly important for the top end of this motor.

Probably beating the dead horse here.. But:
Start the bike with the choke.
3k rpm for 10 seconds.  (This engine can rev to 12k, 3k is not "high.") This helps lubricate the engine as it's been sitting long enough for most of the oil to settle.
Adjust choke to keep the idle around 2k rpm until the bike is warm enough to idle at recommended 1200 rpm with no choke. 
ANYTHING BELOW 1000 RPM IS BAD FOR YOUR ENGINE.
Have a nice day.

For what  it's worth... my starting routine....

Full Choke
Press starter
Let idle around 3k for a minute
Reduce choke so idle comes down to about 2k
Now put on riding gear - jacket, helmet gloves - taking time doing so
Sit on bike and put into gear
Now turn off choke all the way
Ride off Sedately not taking revs about 5 - 5.5k for a few clicks

I've done this since new and bike just had its 30k service and is running sweet, nor using oil. Did a 300+ click ride yesterday in the semi wet with a brand new front tire and she purred along nicely.

Point - a bit of idling at 3k will not kill your engine. And, it is designed to use Full Choke at start when the engine is cold.
