81 GS750EX Headlight& gauge swap. HELP!

[charger71798]

This site is crazy cool! I need help on exactly what is needed to convert from the BIG rectangular headlight to the 750L or better yet the one on this page. http://www.ronh.org/suz750e_82_hr.htm I have a 81 650G gauge package coming and am also bidding on the ones like in the URL. I have headlight brackets. I'm bidding on a 81 750E bucket and a cover with reflectors for the front brake line tee. I'll need a headlight and turn signals from a donor bike. What about wiring? Will my oil pressure sending unit work with a gauge?


My front forks are slightly bent. I was hoping to bid on a set from a 81 750E,but they do not appear to be leading axle like mine. Is this a problem?
Thank you so much for any help!, Cris

If you're referring to this guy's stuff - http://cgi.ebay.com/ebaymotors/Suzuk...spagenameZWDVW , all the parts in his auctions are mislabled, they are actually from an '82 GS750E.

I have converted/swapped out almost everything except the gauges on my '81 to an '82. If you are using gauges from a GS650, you will probably have to deal with rewiring the final connector(s) because the plugs to the wiring harness will be different.

If you go with the center axle forks, you'll need to get the front fender off an '82 as well, the mounting points are different. You will also need different brake caliper mounts. The angle is affected, so the center axle caliper moutns have different mounting hole spacing than the leading axle caliper moutns.

Also, the gauge in that gauge package doesn't read oil pressure, it reads oil temperature. the GS650 gauges have an oil pressure light same as your GS750 gauges, sot hat shouldn't be a problem.

If you are just looking to replace your forks with straight ones, it would be a whole lot easier to go with forks from an '80 or '81 750E that are identical to the ones you have.

What if I just use the upper tube with my original bottom forks?

What if I just use the upper tube with my original bottom forks?

The forks are completely different top and bottom. See the little silver things at the bottom front of my forks in the second pic? Those are anti-dive units that Suzuki intorduced in '82. The internals of the '82 upper forks are different than the '81s due to the internal valving needed for the anti-dive addition.

If all you want to do is get some straight forks, I still have the originals off my 750E. You can have them for $15 plus shipping if you want. I'd recommend changing the fork seals and fork oil in them before installation.

I'm really not planning on using the 650G gauges. I would like to get the ones with the little fuel & oil temp. gauges like ronh's 750E. Will the oil temperature sending unit work a gauge or just a light? Can I just get a different sending unit if need be? Are the rubber grommets for the back of the light bucket separate or must they come with a harness.
I really appreciate all the help. If you need help with your Dodge ask me.(different forum of course) Thanks, Cris

No, it's only for the oil pressure light. It is not a temp sending unit, only pressure.

Can I just get a different sending unit if need be?

I don't know where the '82 took it's temp reading from. That would require some research of the parts diagrams at a place like www.babbittsonline.com

I'm not really sure what you're talking about here. There aren't any rubber pieces on the back of the headlight bucket. Do you mean the rubber seals where the wires enter the gauge cluster?

I don't own a Dodge, but that's ok. There are many on this forum who do. Just pass the help along....

Yes Griffin I was referring to the seals where the wires enter the bucket.

[Griffin]

Truthfully, I dunno.

I may be biting off a lot more than I can chew! Really did'nt think there would be so much non interchangeability.
