Yes, but you've fuel injection & an ECU which will allow you to do that. I will need to manually adjust, by playing with jets, which means recognising that there is a lean or rich condition. Realistically I would use the gauge to set up the carbs, then take it off. Just another tool.

The only reason this has come up is I'm considering options re the exhaust.

If there was enough interest you could buy one as a syndicate?

Bugger about the exhausts but you'll be able to offload them reasonably easily I would think. The GSXR pipes are quite nice looking, it's the length of some that can be an issue for me. I like the look of the Arrow or staintune cans - simple & round - they would suit the bike quite well.

The ground clearance is an important issue for me as well. I think the Maunga would prob be the limit I'd take Schmidt on nowadays, I was banging a fair bit on the non challenge bits on the DB so there would be no way I'd take Schmidt on the challenge sections on that.

I’d be keen to do this. Just nominate someone where it lives.

Shame about the 2-2 exhaust. I take it that it only fits the paralever bikes?

Pete, the USD10 version is a narrow band fuel/ air meter - not supposed to be terribly accurate. The others are what I've been looking at. Seems to be cheaper to buy them in NZ, given the postage that some of the US sites / ebay vendors want to charge.

There's a few companies offering those with free postage too.
Most mention "stepper motor" though. Dunno what that's got to do with a digital A/F meter?

Cold Kiwi attempt

I made an attempt on the Cold Kiwi this weekend. I had done some more work on Gus since the MMMM, including:
  • Putting the exhaust back to stock. The original exhaust header had been welded up with a sleeve to cover the hole. There was a bit of weld intrusion into the header, but I decided it could stay there, given an intention to replace the system in the near future;
  • Taking to the carbs back to pre-exhaust swap settings;
  • Ditched the choke eliminators;
  • Replacing the left fork seal. This was a new All Balls seal again (the 2nd of a pair I bought a while ago - I've had not had any issues with the right side, & have left that side alone). I shortened the springs - they untwist, you can cut them, & then rejoin them. This was to put more tension into it them, with a hope that they would perform better. I also put less fork oil in the leg, to reduce air pressure on compression;
  • Put a new Motobins R100R centre stand back on. This sticks out further than the GS one & is slightly shorter, but still works;
  • Taken the side stand off & replaced it with the stock item
A test run down Glenside Rd appeared to show everything doing what it should.

BUT…

Friday afternoon, running down the motorway highlighted a miss at about 100kms, when you throttled on. Intensely annoying. Right, I thought, just getting a bit lean when the throttle is cracked. I’ll raise the needle one clip at my first stop.

Pee break at Ashhurst, then did some work to sort the issue (in front of a bus load of school kids - 'whatcha’ doin’ Mista……That’s a big tank'). The spark plug on the left side looked real lean looking & kind of old, the right side seems fine, but that has always appeared slightly richer. I went to take the top off the carb, aaannndddd I’ve left my 3mm Allen wrench at home.

Bugger….

So off I toddle to Bunnings in PNth. More stripping down. Shift the clip on both sides. Then back on the road, and it’s not sorted.


My one photo for the weekend

Double bugger…

Back to Repco, PNth, to get a couple of new spark plugs. Swap those out. Maybe I should have left the right side needle clip alone. It’s real sooty now.

By this time it’s starting to get dark. So I decided to call in on Mum & Dad, sort the issue in their garage, then go on in the morning. I couldn’t see any point in having issues on the road, in the dark, or trying to set up a new tent at the Kiwi in the dark. One of the primary reasons for going to the Kiwi was to do a ride with Rosie & co Saturday morning, and if Gus wasn’t going to cooperate then some of the appeal went right out the window...

Swapped out plugs, & checked out all of the normal culprits that night.

Next morning, nothing has really changed. I called into the Honda shop & got some OEM seals to fix the fork leak once i got home, & then I turned around & headed for home. On the way home, because I wasn't in any hurry, I called in on some old friends (the Blobbys) that I hadn't seen for a couple of years, for a catch up.

Today, out to the garage with a list of things to do.

In order to fix the weld intrusion, which I thought may have been one of the issues, first I had to take the muffler off. The muffler has had a leak from where the end bracket used to be ever since I got Gus, so I decided to just weld the bracket back on, & block those holes. Of course the weld just blew thru' again, & every attempt to patch it has ended miserably. So.....I won’t be fixing the weld intrusion after all.

Is now a good time to admit that in my search for stainless to make a patch with, I discovered a couple of Mandy's old knives were stainless? Obviously these were then sacrificed to the cause. Top of the exhaust now reads made in Sheffield...

Keihan 2 into 2 here we come again…

It's just the gauge.

I've promised Mandy to reduce spending for a while, given she has finished up work (been in casual full time work for the last 6 mths). So this has taken a backseat.

If you disturbed the floats when adjusting, worth checking the little spring clip thing that connects float to float needle. If this is not correctly connected the float and needle don't stay in lock step and the fuel level can get low in the float bowl, leading to a miss or even fuel starvation..

Triple bugger Nutso.
Can we recap a minute.
You have done the timing chain aye? - timing now spot on?
You haven't changed the jets have you - just lowered & raised the needle?
floats ok?
Air leaks around the intake?
choke returning properly? cable holders right way up?
Valves all good?
Would trialing an electronic ignition unit be a good idea to see if it's something electrical?


I've got my stuff at the machinists waiting. hopefully by next weekend I should have the engine back together.

You can't post things like that on the net anymore - checked out this thread? Very funny & sad at the same time.

Checked, as well as float height, & also for crap in the needle jet. Idled fine, pulled well everywhere else, just had this issue at open road speed, when the throttle was initially rolled on. 100kms = 4200rpm. If you look at some dyno runs for modified R100GSs, this is where a flat spot occurs. Usually exhaust related.

Yup, checked all of those. Don't think it was ignition related.

Given everything was back the way it was pre-exhaust swap, I've put it down to a change in exhaust dynamics caused by the weld intrusion. Given that the exhaust is scrap now, I guess we'll never know.

Maybe you should have had the head skimmed 1.1mm to up the compression?

So we've just had a big pork roast for dinner, with all the trimming, ostensibly to celebrate Fathers Day. But I've been left with the dishes. Now we have a (nice new) dishwasher, so normally this isn't an issue. But Mandy seemingly has used every dish in the house, including a lot which either don't fit in the dishwasher, or can't be put through the dishwasher. Also there is about 1 & 1/2 loads to do. Is this a test?
