No surprises in the PO Box again today... I think maybe the seller has gotten together with the seller of my manual and decided to combine postage by shipping the HEI modules via New Zealand with the manual... :rolleyes:

Bought this on eBay this morning too, just waiting for the seller to send me an invoice with postage on it. I'm guessing he's waiting for Monday in the US:

http://cgi.ebay.com/ebaymotors/ws/e...0494460561&viewitem=&sspagename=STRK:MEWNX:IT

I can't believe you can't buy these here, or if you can they're extremely rare. There must be hundreds for sale in the US and the only difficulty I had was finding one where the seller was actually willing to respond to a question about the postage cost.

Anyways, so tonight I pretty much finished up the electrics tray except I'll need to file all the sharp edges yet and finalise mounting:



I think if I get some thin hose clamps and feed them through slots cut in the tray where the four brackets curve over, that should mount it pretty securely.

It's big enough to cater for the heatsink I got for the HEI modules as well as the R/R to sit underneath to maximise air flow:



The starter solenoid will probably end up underneath as well, so on top can be the HEI modules plus fuse(s) and indicator relay.

I'll also need to cut out an entry point for the harness at the back left as well.

I then went and got my temporary fuel tank sorted.

Enlarged the existing hole and whacked a grommet in:



The grommet's just an electrical one, but where it sits it shouldn't be soaking in fuel so should be fine.

Fed the fuel line in so the end is right in the bottom of the tank:



Hooked up the fuel tap:



And with some rope on it hangs conveniently from the left 'bar higher than the carbs so it should feed well:



Now, given that the exit point of the tank is so high up, I expect I'm going to have to syphon to get the fuel flowing to start with, and then the gravity feed should take over.

I don't expect the carbs will suck the fuel up from the bottom of the tank there, although if they did that would be awesome.

And the reason I didn't put the exit point at the bottom of the tank is simply because the only grommet I had was an electrical one, so not neoprene or anything fancy like that and I also haven't got anything handy that would seal it up that would be fuel safe.

So, fingers crossed I'll get some HEI modules tomorrow... I still ain't holding my breath though!
 
Still no parcel, but after talking to my wife and house mate, I've learnt that small registered parcels are the slowest form of mail with Australia Post and are known to take a week or more. Great, just frickin spectacular. Good onya Aussie Post! Oh well, glad I wasn't holding my breath!

Anyway, paid for the GSXR left control this avo after getting the shipping cost from the seller, so hopefully it'll be here in a couple of weeks.

So, went down tonight and trimmed the electrics tray up a bit because I wasn't happy with the fit.

I want to be able to just drop the tray in from the top, whereas I cut it a little large so I initially had to put it in from underneath, but of course that won't work with the brackets curving over the frame rails.

So, trimmed it down a bit tonight and also cut a corner out to let the harness in:



I made it a little messier because I only had a little to trim off the edges, but hopefully a good go with a file will clean that up a lot, just can't do that at night as it's a little loud.

I then decided to measure up and design what should hopefully be an effective choke cable bracket to mount on the left carb.

This will mount on the front left bolt of the left carb at about a 45 degree angle towards the rear of the bike.



I need to also make up an adaptor from the cable end to the choke actuator, but I can't really do that until I get the GSXR left control here and know what sort of cable I'll be able to use for it.



So, here's the bracket design:



You can see the sections I'll be cutting out to make it an angle bracket and allow a fork type bracket to actually hold the cable, as well as a couple of dashed lines where I'll bend the tips up to prevent the cable working it's way out of the bracket. In that regard I basically copied the throttle cable bracket for the carbs.



I think that should work okay, and the only thing I can think that I may need to do extra is mount a spring to help pull the choke shut again, but that shouldn't be too difficult.

So, back to waiting again...
 
Mr. Pete,

I must say you have a project on your hands! I am most curious to see if the HEI modules work OK. I have a 450 as well, and although I am confident in some igniter's that are being shipped to me from an awesome member, I'd like to see if this works on the 450 2 cylinder model.

I wish the parcel much speed to your home in Australia!

Yeah I did seem to set myself up for a bunch of work... while it's been challenging, it's also really enjoyable, and so far I've got a lot of satisfaction out of it.

However I'm getting a tad frustrated at the moment because I seem to just be in a holding pattern waitiing for the HEI modules to show up. If I knew small parcel post was this slow when I ordered them I would've asked how much extra for express post!

Anyway, on a positive note, I should hopefully be ordering a bunch of stuff like K&N pods, front sprocket, chain, and some other odd bits on Friday.
 
Finally!!!



However, today's my cat's birthday, and we're a little odd in that we celebrate all our cat's birthdays, so we've had some sparkling red wine and while I'm still quite sober, I'm certainly not up to testing ignition components tonight.

I did however duck down long enough to have a look at how they'll go mounting on the new electrics tray:



They'll sit well on top with the indicator relay with room for a fuse box there as well.



Underneath will be the heatsink and R/R so they get plenty of air flow. I'll find somewhere lower down on the left side for the starter solenoid in the vicinity of where it would be on the OEM electrics plate.

As far as mounting the HEI modules directly to the heatsink, I should be able to cut two holes out of the tray to allow them to bolt directly to it, leaving the centre area of the tray intact so I can bolt the heatsink to the tray. If I don't do that, then I'll have the modules heating up the whole tray, which will then heat up the heatsink, which isn't so efficient.

I'm trying to think if vibration will have a negative impact on any of that, but I may be able to reverse the modules and mount them back to back in the centre of the heatsink, allowing me to bolt the heatsink to the tray via each corner.

None of that will probably make sense to anyone, but that's cool, I will endeavour to work it all out over the coming days. First thing is to sort out the actual circuit.

On another note, put an order in today for...

- K&N pod air filters
- K&N recharge pack
- K&N oil filter
- Front sprocket
- A 530 Triple S brand 104 link O ring chain
- Cable luber

Wasn't terribly cheap, but I had a 10% off voucher from buying my 'bars and rear sprocket from them, so that made it a bit better.
 
Yes waiting for these has consumed you.I'm glad to see you finally got them.
 
I agree great weather for tinkering and drinking!
probably best in that order too.
 
Indeed it is John!

As it turned out, I did get a little tinkering done... and I mean a little.

As per my ignitor thread, first test was a failure, but rushed testing means I don't trust it.

I also got my choke bracket for the left carb cut out of the steel stock and started measuring up and cutting out a mount for the starter solenoid.

I suspect it's going to look very agricultural and ugly, but it should be serviceable for the moment.

No pic's due to not having a clue as to how much time I was going to get on it today, so will post some up next time I'm working on it.
 
Well, couple of testing failures for the HEI modules tonight, details are over in the ignitor thread. Gonna be, well, interesting getting them working.

I did however decide to make sure I ended on a positive, so I got my choke bracket almost finished:





You'll notice two holes there as my initial measurements had the fork hanging way out the left side of the carb which would mean a rather extreme angle would be needed to get the cable back to the choke actuator.

I hadn't drilled the hole until tonight, so I went old school to keep the noise down:



I've gotta work out an adaptor/bracket so I can attach the ball end of the cable to the actuator yet, but I really wanna concentrate on getting spark this week.

Pete,

Here is the cable diagram. I've tried twice to get this right side up and can't. Maybe it's right side up for you, in OZ?

Cheers Charlie, that's awesome!

Can you believe it really is right side up?? Haha... no idea how that works...
 
Probably typical browser refresh issues. I've had photos I've edited and rotated etc. with Photobucket but no matter what I do they show the same image and it's only with a cache clear in Internet Explorer that they show up right.

On a slightly different topic, there'll be an update in my ignitor thread shortly, and I really need to stop looking at eBay.

I bought this today after getting the measurements from the seller as it should suit what I'm looking for:

http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=200583348299&ssPageName=STRK:MEWNX:IT

Obviously I'll need to work out how to mount it to my frame and recover it down the track as the colour won't suit, but I thought it a fair price considering it seems to be in pretty good condition for its age.

Can't see me getting to a wrecker any time soon so I think I'm going to have to stick with eBay for things like this which is a real pain.

I already know that if I manage to get my spark sorted out by this weekend, I won't be able to try for a start anyway.
 
Well, ignoring my frustration with spark, it was fun tonight.

Got home to find two parcels on the dining table waiting for me.

Firstly...



One reproduction factory service manual received! Seems to be quite a lot more involved and detailed than the Clymer, and the only disappointing thing for me was that they don't go into any detail about the ignition system.

I was hoping they'd have some sort of details on the signal generator, but the main part only discusses the contact breaker style, and then the rear has an addendum that lists the pickup coil resistances, but that's about it.

I'm not complaining though as there's a bunch more stuff in there and they cover all the 450's from '81 through '87, so it's thorough!

Next up:



Front spocket, Triple S O ring chain, pair of K&N's, K&N oil filter, K&N recharge pack, and a cable luber. That's the sort of delivery I like to get :D

Now I'm absolutely desperate to get some spark, get the exhaust made, and start rejetting fun...

I haven't received the Katana seat yet, which means I won't actually get it til Sunday as it's going to the house mate's work and he won't be back home until Sunday. Oh well, not urgent.
 
where did you order the repro manual from? I'd love to get a copy of that.
