Regapping the crank positions sensor or ignition pickup coil

Has anyone successfully regapped their CPS also known as the Ignition Pickup coil (from 1mm to 0.8mm)? If you have, was it a pretty straightforward job?

Where there any hang-ups, scratch-your-head moments? Any pitfalls I should look out for?

Also, do I need to order a new gasket for the cover?

Also, does the newer part number for the pickup coil (non-EFI) work on older models?

Hello
Setting the gap on the pick up coil is an easy job. Just hold the coil down with a 0.8mm feeler gauge in place and tighten the mounting screws. An extra pair of hands is helpful. I have had the cover off a couple of times and i was lucky in that the gasket remained intact, stuck to the cover. As has been said before.....your results may vary. A new gasket is not expensive ($AUD10 in Aus). I have a gasket but did not have to use it. I am sure it will come in handy one day........I am going to take the cover off again next winter to polish it up (I have corrosion under the clear coat) and may fit the new gasket then. BTW it is not necessary to drain the oil, just keep the bike on the side stand and have a rag handy to catch the small amount of oil that may run out. A good idea to leave the bike on the side stand for a while to allow the oil to settle on the clutch side of the bike.

Hardest bit is getting alternator cover off. If it hasn't been removed recently, it may well have stuck to gasket, and will need a bit of a jar to remove it. Also, the magnets on the rotor/flywheel are quite strong, and so "pull" the cover back into position. You will need a torx bit for the two pick-up coil bolts.

For me, the hardest part was jarring the bolts loose that hold the pickup in place. Because of the age of your bike, I'd be prepared for that also. Triumph uses some sort of thread locker in there.

Make sure that you have a good torx bit. In the end, I ended up having to soak the bolts overnight with penetrating fluid, heating them with a heat gun, and using an impact driver (it's a little unnerving hammering on an aluminum motor). And still, I gnarled the heads up and had to replace them. I ended up replacing them with hex-keyed (allen) bolts.

Most members that I've corresponded with don't bother with the locker again when replacing. So I followed suite.

Regapping is a very good idea. Get the cheaper possibilities out of the way. Since you're in there, though, one idea is to completely remove the p/u coil and boil it in water and test the resistance. That's what I did and was able to eliminate that problem without buying a new part.

BTW I, being an impatient person, made my own gasket from gasket material purchased at any automotive parts house. I got the slightly better rubber based gasket instead of the paper. For $5.99+tax I made my gasket and still have enough left over to make 2 more.

Don't forget to use a little sealant in the corners where the coil wire enters the engine case. Gaskets/rubber gromits don't seal the greatest in corners.

Re: shutting down problem. Did you check your seat pan to make sure it's not rubbing the igniter/CDI?

I'm worried it's an ignitor problem. That's a $250 problem right there and I'm not quite ready to confront it haha!

I guess I should just go for a procom unit.

Luckyduck... Check the seat isn't making contact with the igniter connector as there have been quite a few cutting out problems caused by this.
Remove the seat and place a piece of plasticine or similar on the connector, replace the seat, sit and bounce on it a few times, remove and check for any contact marks.

Another member (I don't remember who) had a similar problem just last week. He had loose wires in the plug for the igniter.
