1150 Twin Spark Running "fluffy"!

[ianran]

you've never ridden through Glencoe on a 500/4 in the rain then, with a great light show under the tank as first one, then two and three plug leads and caps break down and leave you on an very heavy 125.
Or a Suzuki TS125 that required a plug change 5 mins after starting and needed the points reset before coming home from every rally - could do it by eye in the end.
Only happened once on the R75/6, but that was going up the M6 in a snow storm with cherry red header pipes.
The Montesa Cota coil packed in when I was offroad solo in the middle of the Mourne Mts, lucky the tracks were downhill to the main road and then a 3 mile hike in wellies to a phone to arrange a recovery.

Did have a Suzuki 750 kettle that always wanted to be a 250cc via being a 500 which got hydraulic lock and shattered a piston.
A 750 trident that through a pushrod chasing a commando and an rd400 that welded the top of a piston to its barrel!

Mine has been doing the exact same but as its under warranty i managed to get them to replace both primary coil packs and all the spark plugs too

Runs as sweet as a sweet thing all the way through the rev range now

Coil thngermy changed today runs sweeter than the sweetest thing now
Got a spare coil as well for when it fails again

Just to add to this i recently visited Neil to have my pinion bearings done ,
on the way home i could smell burning stopped and had a look round bike but could see nothing wrong so carried on then the bike started to run badly the penny still didnt drop i got home put bike in garage pulled off cover over stick coil to find it had either caught light or got very very hot, it had not only cooked the stick coil bit also burnt about four inches of wiring loom .
I rang motorworks to see if i could get a piece of wiring to replace the burnt bit only to be informed that it was a one piece loom and would need a replacement loom at £600 and they said BMW would charge £400 to fit it ,
Anyway the guy said he wasnt sure if it could be repaired so asked one of the other guys who said that BMW did a repair piece for the loom for £47 so with the stick coil it came to £115 with vat much better you must agree .
Just to add this is the third stick coil i have had go the others just failing if you do have one go make sure you replace it with grey topped coil which is improved version .

Call me paranoid but I bought a 2nd hand one and a new one from motorworks, both look same colour so is there anyone sad ( I MEAN HELPFUL!!!) enough to have a photo of the grey ones???

The flat top of the new type are light grey, the old type are black

Ian....as Neil said, the old ones are black, completely, no grey on at all......the newer type are all black apart from the flat top (ad inch or so square)....so if yours has any grey on it at all, it's a new type

The coil I bought from pidcocks 3 weeks ago and sold to Ian was all black, brand new latest stock, with the new BMW part number.

Colour alone to identify a new or old style may not be definitive.
