Cold start lurch
- Thread starter Engineer
- Start date
Some numpties might start in on the side stand with it in gear and clutch pulled in - then climb on board, not sure why they might do this but there are all sorts of strange behaviours, as are seen on this site every day!
is it more than a bit dangerous to allow a child to start and rev a bike like that ?
if his foot got onto the gear lever , it would engage and although the sidestand switch will kill the motor , it wouldn't kill it soon enough to stop the engine's momentum sending the bike forward and off the sidestand.

Tested that as worst case scenario. Its fine. Minor movement. Engine dead. Anyway he knows not to stretch for it. If he does then he cant go on it. Simple. He's good like that.
The OP seems to suggest that he has a problem starting the bike from cold in neutral, as he states he eliminates it by putting it in first gear and pulling the clutch in. if that is the case it would suggest an issue with the gearbox having excess drag when cold.
I think there is some miscommunication here somewhere, either in the transmission or reception.
1. The clutch has drag
2. If the bike is placed in 1st gear with the clutch lever pulled in and then the engine started the bike can lurch forward due to the clutch drag.
3. To eliminate the 'lurch' before pressing the starter simply move the bike back or forwards a little - it appears to 'free up' the clutch drag and eliminate the ''lurch'
Simples!
Are you sure you went to school?????

So...I'm guessing you fall into "Civil, Chemical, Sound or Electrical" ?.........Much like a "Doctor of Philisophy" calling him/herself..."Doctor"......

I repeat, define Engineer - I am guessing that you can't
In exactly the same way as you would think 'real Doctor'. Without the accredited degree level qualification for those that have been in the industry for eons, there should be a demonstrable level of vocational experience regulated by an industry recognised body. IMO it should be illegal to call yourself an engineer without this.
I agree with a lot of that and I used to be registered and have the necessary qualifications - I de-registered myself because in my opinion the UK Engineering Institutions do a very poor job of promoting our profession, they have turned into a self serving organisations and have been promising much for the last 40 years and delivered little.
Interestingly, in my technologically fast moving sector (electronics R&D) most Engineers do not bother registering, many of them have masters degrees and PhD's are are vastly more experienced and knowledgable than most of the registered Engineers that I have come across.
Other countries in Europe have much tighter control over who can call themselves Engineers and consequently it is a more respected profession than in the UK, those countries also seem to have a much better manufacturing industry than us too.

I work in the gas industry as a gas engineer and registered. The definition for "engineer" is latin for "intelligent/clever person".
Plumber is also derived from the latin word "plum bum" the latin word for lead the material used for early pipework now outlawed in this country and most of the EU.. People who work in my industry are revered around the world and most sought after. Qualifications in this country in the gas profession are second to none in the UK.

Washing machine engineer? TV engineer?
Anyone else remember when they were called "repair men" and the term Engineer was given to those who built impressive "stuff" ?

Gas safe registered engineer. Legal requirement to carry out any gas work. Cant work on live gas without registration. Would be a court case and possible imprisonment if found to be carrying out any gas/flueing work... gotta have it.
Hmmmmmmmmmm - we have digressed a little from the original topic
