Bombsquad's 1993 GS500e refresh

(1/21) > >>

bombsquad83: question in the General Area was turning into more of a build thread, so I thought I would move on to here.  Plus now I have pictures :).

I got my 1993 GS500 back in August last year, and I've been working on it ever since.  I've done a lot of work to refresh it from it's neglected state. 
EDIT: Forgot to mention she only has 6,3xx miles :).

As I said in my other thread, I've done a lot of work already.  It started out with a 145 main jet, so I'm thinking the previous owner had a lunchbox or something on it.  Exhaust seems stock.  I'm now running the stock airbox with a new OEM filter and 125 mains and 40 pilots, 3 turns out.  I discovered it already had progressive springs when I did the fork seals.

Update 3/26/12
Running very weak in the left hand cylinder.  LH cylinder dies with choke, this explains the RPM with choke issue.

Update 4/1/12
Rode it around town for 35 miles today.  Runs great once it's warmed up.  I think it's too rich at idle on the left hand cylinder.  Gotta review my carb work.

Update 5/5/12

Fixed my one cylinder choke issue by cleaning the starter fuel jet at the bottom of the float.  Tried again to fix the gas level issue in my float bowls.  Cleaned my old needle valve seats and replaced the new ones that came with the kit.  Several tries at adjusting the float height yielded decent results.  I will be checking my plugs for richness periodically until I'm happy with it.

Update 6/8/2012

Finished the paint, decals, new grips, and tank protector.  Pictures on Page 4 of this thread.

Here's a picture of how she sits right now...

Today I worked on the tank and prepping the plastics for paint with a buddy of mine.  The tank had a coating of grey stuff that is probably Kreem or something that was flaking off pretty badly.  It also has a big dent a few smaller ones that are needed filling.  Here are some before pics...

Junk on the petcock

Tried putting an old chainsaw chain in there and shaking it around.  Some of the coating came out like wet leaves, but not all of it.  More work to do here...any suggestions?  Need to look around the forum at what others have done some more.

Here are the plastics before prep.  Some scratches needed filling on one side.

And everything after prep. Decals scrapped and sanded off, bondo applied.

Here is a rough sample of the color.  It's similar to the suzuki blue, with a lot of metallic though.  I was thinking about adding a purple ghost pearl, but I'm not sure I want to go there.  Has the potential to be awesome, or just fruity.  What do you think?

And there you have it!  The goal is to get her running like a top before warm temps roll around here in Central Illinois.

Some gravel and vinegar in the gas thank. That gets into more places than a chain.

Or stainless steel BB's from walmart. :)

I STRONGLY recommend you read this before putting vinegar in your gas tank:

Not to dissuade you, though! It's a cheap and incredibly simple way to get all that SHIZAM out of your gas tank.

Planning on doing a POR-15 treatment.  First I want to get as much of that old coating out as possible.  I will have to try some gravel or bb's or something smaller like that.
