Starting procedure

[Fast Eddie]

Ok folks,

Is there a definitive starting procedure for Brum 961s ?

Specifically, do we give ‘em a twist of the throttle or not?

There have been various conversations about not touching the twist grip during startup cos it’ll confuse the TPS etc in the past. And wondered if this was actually settled by now ?

Have you tickled the carbs and picked a safe landing area !!

You can play around with the throttle until the sun goes down....won't have any effect on the ecu's tps settings. By rights you should be able to just pull the clutch lever in and press the start button....the ecu should do the rest via the iacv.

Thanks Stu.

Oh and BTW Nigel - please; you own a Solihull 961.

 

[Stu Bodycote]

I see them more as a re-release 961

Yeah - WTF - it's not Bracebridge Street!!

I'm in a similar camp - born in a semi-detached at Sutton Coldfield.

Since my excellent rebuild at Motorvated I consider mine as a 'Stued' Donny 961

My 2025 961, always on a trickle charge, has always taken four or five attempts to start, but just before Xmas when it was due to go back to the dealer to fix an oil breather weep, it wouldn't start at all. The chap who collected the bike said by not touching the throttle I was doing it all wrong. He gave it some gas and it hesitantly spluttered into life. It was nearly a month before I got the bike back but then it rained for weeks on end so it sat in my garage until last week. On the first dry day I looked forward to a run but then, despite my using the throttle, it just kept turning over but refused to start.
So I then put the bike on charge using a different charger (well I thought, ridiculously, you never know). Two days later I tried everything but to no avail, the bugger wouldn't even think about starting. So I rang the dealer who said I needed to just give it a whiff of throttle immediately after pushing the starter. So back on the charger again and then yesterday another dry day and no joy. So back to the dealer I suppose.
I also worry now that by my persisting to try to start the bike and then draining the battery each time that the loud clattering noise sometimes ensuing may mean I have damaged the sprag clutch.
Any ideas anyone? Just one question - are the needles supposed to sweep? They don't on mine.

My needles do not sweep. I have a 2014 Sport. If you pull your spark plugs , put on the wire , hold against the head and verify you have spark while cranking over. Try changing the spark plugs with new in case they fouled.

As an aside, you can actually jump start the 961 by (very carefully) attaching a positive starter cable to the M8 stud on the side of the starter, after peeling back the rubber boot, then attach the negative cable to any convenient part of the engine ( or just hold it firmly on whilst spinning the bike over).

That's curious, I wonder why some sweep and some don't. I've checked and there is a spark, plus fuel in the tank.

Thanks for that cliffa. The battery seems strong enough and there is a spark, so I suspect some electrical component has failed, emu or some sensor maybe? It's still under guarantee so back to the dealer it goes, although they can't pick it up until Monday.

It seems nothing in fact has failed. The dealer came yesterday to pick up the bike and it fired up! He emphasised that I needed to give the bike some throttle. I've had a go at starting the bike up today and, on the fifth try, it struggled into life. It looks like either my bike is temperamental or it requires a very precise starting technique, which I haven't yet mastered. I still worry about whether the sprag clutch has been damaged though.

The sprag clutch is within the starter motor, and can be replaced if need be.

Mine has never liked the cold but I keep it on trickle and it is quite reliable. Does yours turn over ok? When you say fifth try does it sound as though it is trying to catch on each try or just spin on the starter. If you run it for a couple of minutes does it then start ok or struggle again?

 

[Beetleything]

If i am outside a Cafe with little old ladies around then i usually start it and then give it a couple of good twists on the throttle

The engine turns over ok but usually shows no sign of catching on. Having said that after four tries yesterday, on the last go it did seem as if it wanted to start, so I gave it one more go and it fired up. It does seem as if you have to operate the throttle and get it just right. I'm wary now of operating the starter for more than a couple of seconds at a time and flattening the battery, because of the sprag clutch. Previously there's been some noises after prolonged attempts. Hard to describe but snatchy as if you had tried to shove a screwdriver into a set of meshing gear cogs.
I've never had a go yet at stopping the engine and then starting straight up again so I'll try that tomorrow. As soon as the bike started up yesterday I went for a quick 10 mile ride and the bike ran well. About five hours after arriving home, out of curiousity, I went back to the bike and it started up third go.

Right, that's exactly what is happening.
The starter "shoves" the pinion gear into the starter gear on the clutch hub. They mesh, then the starter rotates the engine using the primary gears.
Once the engine starts, the pinion gear is withdrawn by the starter.
Normal operation.

Give it some throttle when starting.
