My 1981 GS650G Thread

Ohh I like that new one, but the most important thing is getting it to run nice so hope the jets come in and take care of that for you.

Yeah, I hope the jets will do it for me. The math says they should, I just hope the practical works out.
The jets are supposed to be here middle of this week, and this is the very last chance I am giving the dealership. If they drop the ball on the jets this time, I am neeeevvveeeerrrrrrr dealing with them again.

I was speaking with another of our stores' customers, and he works on lawn tractors and snowmobiles, atv's and such, and he said "Why didn't you come see me? 81 suzuki? Should be Mikuni large style jets right?"

OMG! He knows his stuff all right. I have him checking with his suppliers to see what he can do for me. I kind of hope the dealership messes up again, then I can get a refund and just get jets from this other guy.

Time will tell I guess. Either way I won't have the bike out until I get jets for it. So I guess it's time to finish up the little stuff I have been putting off. Hopefully I can have her jetted and running right before friday when I am supposed to be getting her safetied.

Hey Mac, it's been aaaaaaaaaaages since an update... what's doin? Inquiring minds want to know what the latest is

[Leigh]

That is a damn fine looking air filter.
Nice job.

Hey MAC, you probably explained this before but there are too many posts for me to read through to find this information. So I'll ask it here now accompanied by your very own picture.





What is the piping coming from the intake boot between the carb and head. Where does it go and what does it do?

Thanks.

[Macguyver]

Catching up

Hey Guys (and Gals),

Hey Mac, it's been aaaaaaaaaaages since an update... what's doin? Inquiring minds want to know what the latest is

Yeah, sorry about that. Updates, umm, not much to report. Finished the new dual headlight setup and things ground to a halt when I started the new job.

I spent yesterday putting up a garage-in-a-box car shelter, so at least I will have somewheere to work on the bike out of the weather, so more updates are to come.

That is a damn fine looking air filter.
Nice job.

Thanks Leigh, now as long as I can get the jetting worked out properly, I will be quite pleased with it. I still have to run power to the LED lighting assembly I built to go inside it, but once I get that fired up, I'll put up some pics of it at night. It should be quite interesting indeed.

Hey Don,

The lines run from the balancing ports on the boots to a set of vacuum gauges I have mounted on the handlebar clamp. I have also been toying around with the idea of running the gauges directly on the boots using a longer mounting bolt and an adapter, but I am unsure if the boots would be able to support the additional weight. I know I have seen pics of a destroyed boot before, but I can't remember if the ports are part of the casting, or if they are merely inserts in the rubber.

Thanks for the posts guys, hopefully soon I can make the time to get back on the bike in a serious way. Between having to cancel the appointment to get her safetied due to not having the jetting finished, and the distinct lack of time due to the new job, I have been kind of bummed out about not getting the bike on the road before the cold weather set in.

Hopefully the new job will give me the means to finish her up and get her on the road for some snow and ice quality time.

I will update as time and progress permits.

Good to hear from you Mac! Congrats on the new job and yeah hopefully that'll only help you along once you get some time again.

[pete]

Sorry Mac, had to cut my earlier post short.

Anyways, it's good to hear from you, I was getting a little concerned I hadn't seen a post from you for quite some time, didn't realise you'd started a new job, so congrats on that

Hey Don,

but I am unsure if the boots would be able to support the additional weight. I know I have seen pics of a destroyed boot before, but I can't remember if the ports are part of the casting, or if they are merely inserts in the rubber.

MAC I have a couple of sets of "old" 650 boots in the sged so I took a few pics for you.



Above: Picture of boot from the inside, as can be seen the threaded 6mm hole is in the alloy part od the boot, not through the rubber section.




Above: Picture of the boot from the outside.




Above: In this picture I have filed away the rubber coating to show the threaded hole going directly into the aluminium part of the boot.

BTW MAC we are heading into our summer over here, we are halfway through spring now. Won't be long and we will have 30 degree Celcius days upon us. It's time to finish up our winter projects and start riding.

Your project is an excellent exhibition of craftsmanship and skill. I am especially impressed with the choke setup. A lot of GS riders would prefer that system than the longer cable to the steering head. I have converted my choke to the left switch gear, although my choke mechanism is slightly different to yours as I have later model carbs on my project. I will try and work out something similar to yours at a later date. In my opinion simpler is better.

[pete]

Don, bit of a side note here... how did you get your choke on the left switch gear?

The 450 choke is directly on the carbs but I want it on the left 'bar, sorta the opposite to what Mac has done.

PETE, not wanting to hijack MAC's thread here I have posted the info on your 450 Rebuild thread. Or will have done in 5 minutes or so.

Sorry MAC.

Cheers Don, and don't worry I'm sure Mac wouldn't object to a temporary side track here

[Macguyver]

Hey Guys,
Thanks for the replies and kind words, I am hoping after this initial rush to get up to speed on the new job, I can get back to my projects.

Thanks for the pics Don, that clears up the issue of what to do with the vacuum gauges. Now I need to do up 4 adapters to solid mount them off of the boots. That will definitely clean up the looks around the handlebars.

What the??? Thread -jacking on the GSR??? Nah, never happens.
Don't worry about it guys, I know I have been accused of it before...but never convicted.

In so far as the choke relocation goes, I am waiting on a quote back from the fab shop down the street on custom CNC plasma cutting some parts out for me so I can manufacture some choke relocation kits. Plus, it gives me an excuse to get back into the blueing salts for doing black oxide coatings on parts.

I hope to have the supplies in this week to mix up the salts, and then I can do my own coating. When I can find the time...

Cheers guys,

[Suzuki_Don]

Thanks for the kind responses MAC.

[AF_Bill]

Hey Mac, whats the story on your 650?? How's it coming along?

[Skateguy50]

yes we want updates, hope to see you riding the 650 this season and hopefully make it south to a rally or 2.
