Spent a bit more time on the bike today. Ran it for nearly five miles with no issues. Whilst it was ok tried putting the choke on to see if it made any difference. It didn't. Tried going down to 3000 revs several times and every time it picked up ok. Got to about 5 miles and she started to play up. Pulling any more than 1/4 throttle resulted in severe stuttering. Tried putting on the choke whilst the stuttering was happening, didn't make any difference. Road her home.Replaced fuel filter and a friend lent me a set of vacuum gauges to check the carb balance. Had to adjust 3 & 4 ever so slightly. Bike was now getting hot and fan was running as expected. Blipping the throttle when the bike is hot results in a little stutter as you flick the throttle.After the balance I thought I would remove No's 1 & 4 Diaphragms. They look and feel fine. The rubber is soft and supple and no signs of holes. I also removed the plugs and apart from being very slightly black they were fine.After I had put everything back to together the bike had cooled down a bit. I started her up and blipped the throttle without any real sign of the stutter. Got to be heat/time related.I'm now leaning more to an ignition or some kind of electrical fault. If it was a carb/jets/diaphragm issue then surely it would occur from the start.What effect would a pick up sensor breaking down/overheating have?Have a short couple of video's I took on my Iphone of the carb balance but don't know how to load them.
I'm thinking of buying a replacement coil to hang in whilst fault finding. I believe a cheaper and better mod is to fit NGK plug caps to the leads. Can anybody tell me which ones i need to buy for my 600 2003. Also has anybody bought an aftermarket coil. Cheers John S

I have a similar issue to you the bike pulls fine then hits a bad spot like the fuel of spark is been turned off from around 6 to 10,000 rpm.light throttle no issues at all and it pulls Up to 6000 fine, from cold it's much better.And I have a ticking noise similar to a spark arking I'll be taking the leads apart shortly !!!.Glad you sorted it Sent from my Nexus 7 using Tapatalk 4 Beta

It is good idea is to take all connectors apart and spray with WD40 while checking for chaffed wiring. A common place for corrosion is on the fuel pump connector and the pickup up connector.Hi Unfazed. I checked the Vacuum plugs when I did the carb balance. They look ok. Visually checked the loom from the Pick Up Coil we're it comes out of the LH Engine Cover. Also had a look at the connectors under the LH side cover. Nothing obvious there.The Haynes manual states if you want to replace the pick up coil as its part of the Alternator it has to be replaced as well. Need to be sure it's the problem as that will not be cheap to buy.
