Re: 860GT runs rich --- try smaller pilot????

Hi Kara: fiddly neutral is a very common problem; my old 860GT was more hit and miss than my MHR but I still try getting it in neutral before I actually stop. A clutch pack inspection is really easy. What you may find is serrated slots on the housing where the steel clutch plate tangs have bitten in...

Re: New ignition system: need advice!

I'm talking about the pickup circuit board inside the engine, not the external black box!

Re: New ignition system: need advice!

I would contact Sachse and see what they say about replacing the pickup circuit board only (and buying the same by itself). From pictures in the manual It looks like the PCB is attached to the bigger steel positioning ring by just 2 screws. If so, this is a really quick job. Setting up Sachse igniti...

Re: New ignition system: need advice!

One of the Sachse selling points is that it is an electronic ignition with a selection of built-in advance curves. All have one thing in common: no advance at start. This means that as long as the motor is turning due to being kick or electric started, the spark is not advanced at all, triggering a ...

Re: New ignition system: need advice!

If cooking your Sachse unit is a concern, I'm interested to know where it is located. Mine is velcroed to the rear mudguard adjacent to the battery and seems to keep reasonably cool despite its proximity to the rear head. Did you read the troubleshooting section of the Sachse manual? https://www.ele...

Re: SACHSE Timing question on 860 GT

Hi Kara: It would be easy to make a pair of test LEDs. Just take a peek at the installation manual for my bike, a Bosch bevel 900, downloadable from the Sachse website to see what I mean. Because the Bosh pickups are located in the left hand cover, the test LEDs are an external, test tool only, just...

Re: Sachse Ignition on Pantah

You are correct, Pantahs run a ccw crank as seen from the left side. I figured that maybe it would have made sense to have the the V and H stamps pointing towards the cylinders that they were referring to at horizontal TDC. I can't work out why the stamps are there as they are not referenced in the ...

Re: Sachse Ignition on Pantah

OK, I've read the manual and there are a few differences between your Pantah and my MHR! The manual sucks. Logically, V is vertical and H is horizontal but the location of H and V, albeit 90deg apart don't make sense. The picture of the trigger ring on the crank is not clear enough and there's nothi...

Re: New ignition system: need advice!

Just checked: the new Sachse manual shows yellow and green test LEDS; the yellow is for the front cylinder and green for rear and the pickup leads are now brown, green, yellow, white instead of black, green, white, red. Very confusing because they forgot to change the colour of the LED in the test i...

Re: New ignition system: need advice!

900tlc: It's possible that Sacshe have changed the colours of their test LEDs and there is also a difference in delivery and set-up depending on which bevel 900s you have. In my case, an 81 Bosch, my Sacshe kit was ordered in April 2019. On Bosch bikes, the pickups are in the left side engine cover ...

Re: 1983 MHR wiring diagram

Here's an 81 diagram; I doubt the blinkie wiring is different for the 83. It's common to have issues with the switchgear contacts. I've been lucky but I did take all my switches apart, clean everything and then double check all switch operations before putting my bike back on the road. Grounds are n...

Re: 860 GT Enrichener question . PHF 32

I wonder if this is the same hole that pees gas when a tickler is pushed for too long. It makes sense that the carb with a choke would also have the same bowl overflow port.

Re: SmartCarb in 1976 900SS ?

One thing I should have noted regarding starting is not to rev the bike too much immediately after it starts; I will keep it at around 1500rpm-200rpm with a few mild blips to get the oil flowing and filling. It's particularly important on my bike as I have an oil cooler. Within 20 seconds, It's in g...

Re: How to set the timing on a Mille?

Just checked and they have different part numbers for the Mille/S2 ignition rotor. My guess is that the tool is based on the earlier bikes; the round bit will match the ignition "lobe" outer diameter. You will need to compare that dimension with your rotor and account for it in the air gap setting; ...
