Cheers!

It's been a while. To the extent that I sold my earlie LT/SE and was without a BMW for two years until I imported this one from Sweden two weeks ago. It's a -93 and 59000 kms on the clock.

It seems I need to do throttlebody synchronizing. Queue to dealer is two to three weeks and I cannot wait that long.

There are these two types of devices available locally. Would either one do or would one of them be significantly better?

The one with gauges:

And the other one with fluid:

The manometer type work well if you don't allow the fluid to be sucked into the engine. You can find plans to put together a simple fluid manometer that costs little and will do the job. Search for "home made motorcycle manometer" and you'll see several.
I use the vacuum gauge type for carbs and EFI throttle bodies. They are rugged and plenty accurate for the job.

I have the Carbtune that Duck suggested.
Purchased it from Beemer Boneyard. Good service. Device works well and has no fluid to leak/get sucked/spill etc.

I got my carbtune from the UK many years ago and it works great. As mentioned no fluid to make a mess or get sucked into the TBs by mistake.

Carbtune ships quickly too. I ordered mine direct from Carbtune in The UK and it showed up in Seattle.much sooner than I expected.

I tried to make one of these to use following the directions/plans online...and had no luck, the fluid would just immediately get sucked into engine etc. I think its very difficult to get everything sealed up, and the restrictors were difficult to get to work right.

The carbtune looks to be good. I just pay a shop 1/2 hr. labor to do it. (i open up the bike as needed) ride over...it takes minutes to accomplish.

And the carbtune is made in Ireland which is always a good reason for buying something
Very Happy
