My better half was warming up the engine of his Blade when a disgruntled neighbour came out and shouted abuse. He asked why my boyfriend was "revving the engine so much" and that it wasn't neccessary to do it.

My boyfriend said he didn't know what he was on about and the guy replied: "yes I do, I used to have an R1... look" (and showed him a scar on his arm where had obviously come off it).

My boyfriend "revving the engine" or using the choke as it's better known as is neccessary as far as I'm concerned because the engine and bike performs better when warm.

What do you lot think? Is the guy a twat who never warmed up his bike and tried to get his knee down so trashed it? Or is he right and we should start pushing our bikes down the road so we don't bother neighbours with noise?

Also, if you agree with me then what should I do to him? I fancy getting the entire North London biking population to start their engines at 5am right outside his window

Never bother myself, can't see the point, it'll be just as warm 100 metres up the road and will have least had a bit of a load upon it. (Although putting ones gloves on might count)

Let me guess - race exhaust?

I'm of the school of thought that you can warm a bike up by riding it, so long as you don't use loads of power or revs for the first few minutes.

personally.....start it, ride it conservatively, gets to 70 degree, berries -> given

Put a noisy race can on and tell him to fuk off. I have miserable twats living in my street like that.
I did used to go to work at 4.30am tho, dya fink i was unreasonable. :burnout:

I can't blame your neighbour. I'm currently dealing with a next door neighbour who has a facked exhaust on his 4x4 and warmed it up for almost 10 minutes at 05:25 the other day.

Rule of thumb, is start bike up, put helmet and gloves on and ride up. The engine needs no more than 30 seconds to get the oil circulating and warm.

no warm up, it only warms some limited parts dunnit?
Whereas gentle riding will warm the whole engine/drive system.

R1 dude's right.

yep unless it's a 2 stroke, RS250 used to take at least 5-8 mins to warm up to running temp...enough time to lock up and get rest of kit on.

Of course!

But the R1 guy did wake me up at 1am coming home on it one night and sped up the road like mad so the c*nt deserves it!

I warm up by riding gently for a couple of hundred yards, as long as you don't rev the hell out of it then it should be fine.

On that note why does your boyfriend rev it when warming up outside the house, that's not going to help at all.

You really don't have a clue.

I'm not suprised the neighbour is pissed off, I would be.

wind your neck in and appreciate that to other people an inline 4 is not the most beauteous of sounds.

If your other half apologises, politely, even in a friendly manner, promises to be more careful in future the neighbour will more than likely be satisfied that you're not Hell's Angels and will go back indoors.


Having done this you can go back to doing what you normally do - run the bike on choke for a couple of minutes then take off.


BTW - what revs does your 'Blade run at on choke? Mitzi's 01 bike (which I'm currently borrowing) runs at 2K on the automatic choke - and if that was going through a race can it'd be a hideously raucous chorus cos the engine doesn't run terribly smoothly at that engine speed.

You must warm modern engines before riding. Modern tolerences for high revving engines mean the clearences are much tighter. An engine under load will warm it's pistons up much quicker than the cooled cylinder wall. You won't really notice a few bhp down on your 150 though I suppose. The thing about 2 strokes is the pistons are not exactly round. It is slighlty small (ovalled) by the exhaust port as this runs hotter and expands more. Of course if it's a 4-stroke and you sell it after 2 years of abuse the nexy guy can worry about it. My bike is 13 years old so I have to look after it :burnout:

You ever see racers go out on a cold engine? They even warm thier tyres for goodness sake!

There's a difference between letting the oil circulate and riding off at low revs than riding a race bike. Letting a high revving engine idle or go way up in the revs without any load on the bike is probably doing it more harm than immediately riding it away.

Any comparisons to a full on race bike are a non-issue.

I am not talking about circulating oils. I am talking about temperature of burnt gasses heating metal parts in isolated areas. Modern sports bikes are closer to road bikes than ever before (vice versa) but that wasn't my main point anyway. Hey it's your bike, warm it how you like I guess. :burnout: But the piston will heat a lot more quickly than the cylinder and that is a fact on any engine. Cars (every day types) tend to be able to take it as they are designed for it. A sports bike is not. Sure you'll get away with it for years like I said but some damage will be done. I have to warm my bike at 4k then 6k blipping for two minutes or risk a cold seizure. Ask your local Honda dealer if they recommend you ride thier new Blade on a cold engine? I am sure they won't as they don't want to risk a warrenty claim. They will tell you not to ride it until the needle (oops bit old fashioned there) or digital HUD has moved off cold and into warm.

Well, in fact it was my local Yamaha BMW shop's head mechanic who said that the time it takes you to put on your gloves and helmet is enough time to ride off at low revs.

And your experience with 2 strokes is fine. I don't ride them much, so you could tell me it takes 30 minutes to warm one up properly and I wouldnt know the difference.

I do know that the old RZ350 (LC350) that friends' owned didnt require a lot of time to warm up either, and one of them was raced.

To say that you'll be doing your engine some damage is saying that as soon as it's started, you'll be doing it damage, warm or cold. That's true, wether warmed up correctly or not.

cant see that there is any technical reason why warming up at sensible speeds on the road is any real difference from warming up standing still. anyway, its not the warming up thats the problem, is it? the problem is the noise level from a bike with , I suspect, an after market exhaust. is it even legal?

personally, if I had a neighbour so inconsiderate as to warm up a bike with a so called race exhaust outside my window at all hours, I would put sugar in his tank. Not saying that this is whats happening here since we dont know- but I can't see someone objecting to the level of noise from a modern factory exhaust.

you have a right to ride your bike. your neighbour has a right to peace and quiet.
