Cheers lads, for all the encouragement .
Continuing from last week, I can now bolt the hub to the adapter I made and machine off the 9mm of material needed.
Bolted in place (the carrier ran very central- I didn't bother to get the dial gauge out)
SDC11727
After many passes and checks,an image of the carrier machined
SDC11728
The rear wheel and sprocket carrier are from a 600 bandit. Suzuki use a strange flat sprocket bolt that is captured by a flat. So I'll thread another 9mm on the 5 bolts and then cut them down by 9mm, that will complete the rear wheel, swing arm and rear suspension. The rear sprocket will be 39T, 520 pitch and from a GS500, which has the same mounting dimensions as the 600 bandit.
Cheers, Mark

Continuing with the sprocket carrier,
This image shows how much of the shoulder of the captured bolt needs to be threaded
SDC11730
So I got the tap and die set out, and cut another 9mm of thread. Using plenty of lube, the bolts cut a thread quite easily.
SDC11731
Then repeated 4 times and I then cut the bolts down by 9mm. A touch of Dremel work to finish the ends of the bolts and the jobs a goodun.
SDC11732
Cheers, Mark

Your posing now on that lathe😆 Be getting one for my new mancave once it’s built👍 It’s eating all my readies at the mo so all bikes are on hold for a while🥴 Anyway keep the updates coming mate,it’s still free to read thankfully 😂

I wish I had a lathe if I ever extend me garage I would seriously consider one
Your a clever bugger I will give you that so impressed with this build and I thought the triple was mental
Looking forward to future updates

Stusco and Reggie, I've got into the habbit of never letting go of the chuck key, and always rotating the chuck to make sure it will spin freely and not hit the tool post. The comment to Dusty was when I tried to cut too much material off, and the work flew out of the chuck. I won't be doing that again in a hurry
Spacejunkie, ages since I've heard from you, is life good? Cheers pal, I would say, get a lathe, they are great fun

I'm booked in with Mick Abbey (living legend), for the exhausts to be made at the end of Febuary. So I thought I'd make the pattern up for the airbox so I can fabricate it while the bike is at Mr Abbeys.
About an hours work produced this bizarre shape (the small blocks of wood are the clamp it in place)
SDC11735
All the heights/spacing's worked out, and I've maxed out the volume of the airbox where I could. Image of the front view
SDC11733
And lastly, showing how much the airbox will stick out past the side panels - Gulp!
SDC11734
It's going to be proper bonkers,
Mark

Mark, I worry about how much air those end carbs will actually get at full bore but expect youve checked that. I say that as I did worry about the volume of the OEM LC airbox on my 421 and for that reason went for pods. The issue as ever with the LC is packaging as its a small bike with a shock absorber right where the airbox needs to go.
I was thinking that you could possibly have a more normal shaped 'two' cyl box and then come around the frame spar and through the side panel with a curved rubber or plastic tube? Obviously it depends if youre using the oil tank and battery box etc.

Obviously it depends if youre using the oil tank and battery box etc. Hi Jon, hope your good. I researched this heavily on the triple, and have almost doubled the area of the passageways in the airbox. The passage feeding the inlet rubbers (carb to airbox) is over 6 times larger than the carb area (reed block side). I also measured the airbox volume on my H1 500 (very similar to the H2 750), and found the LC's standard airbox has over 6 times the volume!! The H1's and H2's seem to go alright . My understanding is the size of the airbox has an impact on midrange, two strokes like a smooth flow of air into the carbs, some pod filters (the ones with the end blanked off) make the air turbulent. I assume your beautiful 421 makes serious power- 80/90 HP. The 700LC will make hopefully 95/100 HP, but it's engine capacity will mean loads of midrange.
You are spot on with the shock absorber is in the way, and oil tank and battery box to spread side wards.
Your right, in that a smoother, straighter airflow would be achieved by ducting through the side panels.
For me the look of the bike is just as important as the performance.
My airbox also looks very much like a GS 1000, similar widths as well.
Cheers, Mark

I started on the airbox this week but proper work got in the way and stopped play . A while back I fabricated my rear indicator mounts and had them welded to the rear sub frame. I've relocated the rear indicators further forward on the subframe (the same as the triple)
SDC11736
SDC11738
Next week I should have all the measurements and volumes of the oil pump
Cheers, Mark

Sorry for not posting for a couple of weeks, just life getting busy.
A few weeks back I managed to set up the oil pump and measure the output of the Rg500 pump after the gear alterations.
Just to refresh you memories - the RG500 pump geared down in the LC clutch cover
SDC11715
I ran the RG and LC pumps for 2 mins 30 secs using a rechargeable drill. The first test was fully open, second test was fully closed (oil delivery on idle), then repeated for the 350LC pump. Both tests were with the drill running at full speed.
RG 500 pump; Max opening 2.5 mins 2.2 ml Min opening 2.5 mins 0.4 ml
LC 350 pump; Max opening 2.5 mins 1.9ml Min opening 2.5 mins 0.4ml
I then had to work out and measure the throttle cable actuation between the pumps.
RG 21mm cable exposed on min 42mm cable exposed on max = 21mm stroke
LC350 24mm cable exposed on min 48mm cable exposed on max = 24mm stroke
So very close and happy with that.
I assembled the rear wheel with the machined sprocket carrier, so the chain run can be checked, and output shaft measured
SDC11741
Cheers, Mark

The bike was booked in to Mick Abbey on the 29th February to have the cylinders matched/ tuned and the exhausts made. So my son Paul and I did the 500 mile round trip and delivered the bike to Mick. I took some photos of the work I've done in the weeks leading up to the bike having it's exhausts made.
I made a template for the rear tray and marked it out on a sheet of aluminium
SDC11740
I then cut it out using a jig saw with a fine metal blade installed
SDC11742
Cheers, Mark

How the hell did you do that perfectly with a jigsaw? Looks like it was done by a computer laser thing. Brilliant work Mark.
