gs450 re-build

[mlc216]

Cut all the crappy randomly placed brackets off the frame and cleaned it up a bit

[mlc216]

Didn't get a whole lot done tonight...


Fab'd up a plate that the reg/rec and the ignition module mount to under where the seat will be.


Tried to get a picture to show how they tuck up under the seat in between the frame rails.

Please excuse the wires as they will be tucked away cleanly soon enough

[mlc216]

Made a bracket and mounted the keyed ignition switch today. Also mounted the fender:


It's super sturdy! I'm going to make my own rigid seat that flows back over the fender... I really like the riding position that this is going to give me! Also, I'm going to shave all the holes and the other mounting "bumps" as well.

Mate I'm diggin' your work, good stuff!

[Big Rich]

Don't know how I missed this one, but I'll be watching now. Good work so far!

[mlc216]

Thanks guys! Look for more updates this weekend. New headlight, taillight, and tag mount for sure. Hopefully I'll get started on the rigid seat and start narrowing a sportster tank too!

[mlc216]

Fixed a few more things on the frame, made a brake switch mounting tab, and whipped up a tag and taillight bracket.

[mlc216]

No pictures right now... just boring stuff. I've gotten rid of all the old wiring. Man was it a mess. Total mess. It's all gone now and mostly replaced with fresh new stuff with soldered connections instead of crappy autozone crimp connectors. Should be done with the wiring tomorrow. Still need a headlight bracket and coil brackets...

[mlc216]

Finished the wiring, just need to tuck it away....got the coil mounts and battery tray fixed up... all it needs now to be on the road is a headlight mount.

Also, what do you guys think about this tank? Gonna try to get it patched up and mounted before the dixie round up...

Oh yeah got my 21 on the front now too...

[mlc216]

Here's my stupid bike as it sits now... That's pretty much all it does right now is sit. It fired right up and rev'd up high for some reason and blew the headlight and taillight bulbs... then proceeded to idle down and act normal. I rode it down the street, but it had NO power at all. Somethings wrong but I don't feel like messing with it anymore tonight...

Perhaps because there are no filters on the carbs? And the open exhausts. Rejet the carbs!

[pete]

From what I understand, high revving or the hanging idle syndrome is bad intake boot O rings or at least intake related, so what FC says certainly could be the cause of that.

However, blowing bulbs says more charging system to me so I'd be checking it as a matter of priority, otherwise you may find yourself with a fried ignitor and that's where the fun begins with trying to find a replacement...

Aside from that, tank looks good

I wasn't sold on your 21 inch front wheel in the original pic, but in the most recent one it seems to fit better, maybe it's the tank/wheel combo or just the angle, not sure...

My guess is that there is junk in the carbs... they've been sitting up for a month or so while I've done all the other work on the bike. It actually ran pretty decent before with no filters and the open exhaust. I'm guessing that the previous owner did rejet the carbs and at least got close... I have another set of carbs I'm going to put on the bike tonight with some pod filters.... and I'll be changing the exhaust up, I was just excited to try and get a ride in since I haven't ridden it in a month...

Pete, I'm actually starting the think that something was stuck in the idle jets causing it to lean out momentarily or even the throttle cable was stuck for a second? Once it cleared it's throat or something it actually idled fine. It just idled way up for long enough to make the headlight turn pretty colors and then die haha. I'm going to check the voltage tonight and make sure my reg/rec is doing its job. I'm hoping that it didn't fry anything else, especially the ignitor box...

As far as the 21... you will soon find the chopper way! haha

[mlc216]

P.S. I just thought of what my voltage issue is. The reg/rec on this bike is a 6-wire model with the extra wire being a voltage sensing wire. It was previously hooked up to ground and I blindly just hooked it back up to ground when I redid the wiring.... when actually it should be hooked to the ignition or power source. So, the regulator wasn't doing it's job, because it couldn't "see" the voltage. I'll switch that up tonight and it should fix that problem...

[pete]

Cool, if it was only a short term thing then quite possibly, and would be a very easy fix if that's it

Also, as to your sense wire, yeah that definitely needs to go to 12v somewhere, well found!
