Stop pulling the clutch in to start the bike

[M.C.]

this does p!ss me off too my CBR would strat with just the button but all i do if i'm standing up is push the clutch in with my leg and then start the bike if my hands are full

i will be doing this mod as it p@sses me off to!

Take it a step further and remove the switch too, it lightens the clutch action a little. TBH I think you've got to be a bit mentally deficient to start the bike in gear anyway And it's one less switch to go wrong and leave you stranded.

But what about the 'Start-up' map that most injected suzuki's go in to when the clutch is pulled in.

GSXR1000's loose 500rpm from the top end before the limiter when the clutch switch is looped.
A few years ago in the superstocks there was a suspicion over a couple of bikes that made more power and revved higher, turned out 90% of the Gsxr's had the clutch switch looped as part of the std race prep and the ones that made more power were std

Since then I have avoided looping things on injected bikes without being 100% on its consequences

I am not 100% certain on how it all works, but if you start a bike from cold and leave it to warm up in neutral it slowly causes internal engine damage.

You are supposed to start the bike and set off within around 15seconds

I am almost certain this was printed in the MCN a few months ago, but it may have been one of the magazines

so starting the bike before you put your lid and gloves on is deffinatly not to your advantage, well not to your bikes advantage anyway

my old kawasaki used to have the clutch linked to the sidestand by a cable. Now that was marvellous as you could amaze ppl my flicking the sidestand up... seemingly magically. And achieved the same as the clutch switch - stopping one from riding off with the side-stand down.

It was a kick start anyway so it wasn't so important if the clutch was in or not for starting.

Providing that all the engine components get sprayed with oil (the engine's idle speed is high enough) then there really is no problem. Only on a brand new bike when the pistons are still bedding in will you likely suffer from glazing of the bores which is best avoided.

You are supposed to start the bike and set off within around 15seconds

If you don't give the engine time to circulate the oil and the internals at least achieve a working temperature then you're going to cause damage riding off too soon. A good thirty seconds is, I suggest, the absolute minimum when riding off from stone cold.

Just do more exercise on the left wrist .

Who are you calling mentally deficient . I always start my bike in gear as I always leave it in gear when parked. I do pull the clutch in though before starting Mr ..wind .

For the FI bikes, (the 1000 anyway, don't know specifcally about 650s but I'd be surprised if there weren't a similar system), this is a good reason for not looping the switch out.
When cold pulling the clutch raises the tickover about 500rpm, when hot the clutch switch operates a limiter that caps the revs so it can't be over-revved accidentally, if the switch is bypassed the revs will be capped artificially and the bike will be down on power in a similar way to the GSXR mentioned.

The TRE mod on FI bikes, (again 1000s certainly, likely 650s too), disables the cold start/running fuelling and ignition map, such that the bikes don't run well until hot, this is why many people, (myself included), have switched the TRE. With a cold engine in town in cold weather, the bike doesn't tickover right and can run awkwardly with the TRE engaged.
