Yep, new retaining ring needed. Luckily I had a few new ones kicking around in the garage.

A quick call to Riders to stock up tomorrow :twisted:

So, new retaining rings were fitted, took SoM for an MOT and she passed...

Oberon bar end mirrors were fitted, plugs banged into the mirror holes on the controls and the timing cover replaced...

It did feel like it steered like a tea trolley, however that was traced to tyre pressures (Avon Storms) being 15/20 when they should have been 36/42.

Pumped those babies up and now it handles like a dream. The rear shock, a Cooter cast-off, is not bad at all. I'll use that until Ronnie goes back to AST and we can get a deal on shocks again...

I cleaned the front disc up, the right hand fork seal had been leaking on it, replaced the front pads (bargains to be had on eBay at the moment - http://www.ebay.co.uk/itm/EBC-HH-Motorc ... 4624c5c4a1) and it stops much better. I had cleaned the disc and pads previously but the oil must have been hiding :P

Had a great ride on it today, pics here - viewtopic.php?p=269131#p269131

I must say, I really do like it...

Still lots to do on it though, including:
* addressing a snatchiness when I pull away in first
* enhanced under tray
* get all the rogue paint off the primary cover
* fit my US speedo (it currently goes really fast)
* fit a new rear caliper
* fit some Renthal Ultra Low bars
* tidy all the stuff I rushed

Is Ronnie going back to AST ? I hope so as the current agent is really really shite :?

I must say that AST tend to pop their seals just as frequently as the Showas do , in fact my Showa managed more miles than my AST , good thing about the AST is that it is rebuildable whereas the Showa was not designed to be.

Don't think mine ever had a warranty lOl Had it for years having bought it from GB once Ronnie had rebuilt it for him after it broke :shock:

Can't see both sides at the same time and the right-side looks always the nicest!

Sister of Muffin continues to exceed expectations, but one thing I have noticed that is spoiling to enjoyment is idle...

I have been finding that if I want the bike to idle nicely at 1050RPM when cold, whilst I put my crash helmet and gloves on - a bit like Freddy here at 1:00 - I end up with the bike idling at 1300-1400RPM when it's warm. And add to that, a slow decel from 2000RPM to the 1300RPM... Grrr...

And I don't appear to be alone, after asking the question to a handful of other X1 owners, they suffer from the same annoyance (although they appear to be more forgiving than me)

SoM is fitted with Race headers and muffler and a Forcewinder, but there has been a minor apology, I have been running with a standard ECM. Not such a big apology as the bits of the map that matter are common between two. And although I was very happy with the static timing, I thought I would do another TPS reset. The difference was 0.02V which is an error of 1 TPS value on the map. Obviously not helping, but I am sure not noticeable...

After the TPS reset, I also loaded the Race maps.

I still haven't ridden it since as the weather is more favourable to windmills than motorbikes, however I am already planning potential fixes...

There are a couple of options:

1. Play with the Warm Up Enrichment table - not preferred as it affects the whole map
2. Play with the Idle Spark Advance Table - I do this on my XBs to have a crisper idle and pickup
3. Play with the Idle Correction - this is a factor on idle fueling and has no effect on an XB as they have a Closed Loop Idle control
4. Invoke the Closed Loop Idle control and do 2.

The Warm Up Enrichment table looks like this:
Image
This factor is applied to the whole map in response to the measured engine temperature.

The Idle Correction table looks like this:
Image
This factor is applied to the idle area (below 1350RPM and below 27 TPS) in response to the measured engine temperature.

The Idle Spark Advance looks like this:
Image
This advance is added to the ignition timing map in response to the measured engine temperature.

So, plenty to play with. My money is on the Idle Spark Advance to give me a good result, 20 degrees (plus the 5 degrees advance on the base map) seems a bit much at 10 deg C.

First, I need to get the bike ticking over nicely when hot as I have since changed the tickover screw setting when doing the TPS reset... Hopefully I can do that on Saturday...

Been doing lots of intersite stuff for work this week, so not had too much time to play motorbikes, however I got in the garage tonight...

I started the X1 up and set the idle adjuster for a 1000RPM tickover and waited as it warmed up...
Image
Check out the amount of advance (17.75 deg advance) at this head temperature (24 degC)

Image
Advance reduces to 13 deg at 47 degC but look at the tickover, its gone from 1050 to nearly 1200 :shock:

Image
Advance down to 10 deg with the temp at 69 deg C but we are up to 1300 RPM...

Image
Backing off the idle adjuster from 6.7deg to 5.3deg brings idle down to around 1000RPM (1092 I caught it at here)

Image
And 1035 here...

So, plan of action is to reduce the advance and try see how it ticks over tomorrow morning when cold...

From this:
Image

To this:
Image

Changes made by setting 0x15F to 3C and 0x161 to 28 :mrgreen:

Let's see what happens tomorrow and if it ticks over with the idle screw in the position for a warm engine...

Couldn't wait until tomorrow so I ventured to the garage with my new EEPROM to burn...

Now, at 20 degC engine temp, it idles happily between 1000 and 1100 (a bit lumpy until warmed up).

Are you just playing around or are you trying to achieve something?
