450 engine rebuild

[phillipjohnw]

I'm glad you asked Jeff. I forgot to post the little hiccup I had with the gs500 cams. Namely the exhaust cams wouldn't fit due to the gear for the tach. I came up with 2 solutions. Remove the tachometer gear and run no tach or use the 45 0cams. I went with the cams because I felt that a tachometer is more useful than not.

I don't know how tight of a budget you're working with but an option might be something like the Acewell gauges should someone want 500 cams. They run electronic tachometers that I've found to be spot on.

What would be the benefits of running the 500 cams as opposed to the 450 cams? How I understand it is that the 500 cams would slightly alter the power band of the engine?

On the Acewell side, I can definitely recommend them, been running mine for well over 10000km's now and still love it.

I also like the fact that you can remove the tacho drive and put the proper blanking plug in from the later 1100's for a very neat oil tight seal.

That would definitely solve the tacho drive issue...

Maybe I'll hang onto these cams and look into that fancy dancy electric tach in the future. For now I just want it to run.

[Guest]

That's cool, just letting you know the option's there

I tend to agree with just getting it running though

I can't quite tell by the pic, but did the cams you got off eBay have the gear cut into the ex cam?

Later gs 500's had electronic tach's. I wonder if the cams were still made with the gear cut into them or they just did away with it.

[phillipjohnw]

Sorry its been a while.

Mekanix I found out the hard way that when they went to the electronic tach they removed the gears on the cam. Not a huge deal, I'll just toss them back on eBay. Hopefully make a few bucks off of them.

Other than that still wading through the wiring trying to get it all tied up and pretty. Hopefully it'll just start up when the time comes. Fingers will be crossed.

[Guest]

Cool. I'm not sure when they went electronic but cams before that had the gear.

[phillipjohnw]

Well Its been a long while and I've made absolutely no progress. I lost a little steam on this project for various reasons, but I'm getting it back on track. First order of business is the mess that is the wiring. I plan on running a pretty minimal setup, while still using mostly stock controls for now. This is definitely in the wrong section but does anyone know a good type of connector for bike use? Hopefully in the next month or so I will have it running. Time is the limiting factor as always. Hopefully some of you, Mekanix, can toss a little more knowledge my way.

Stock is pretty minimal as it is.

I used mostly TYCO weather proof connectors for my build.
There are single up to 6 pin connectors that I know of.

Motivation comes and goes. Try picking at it until you get on a roll.

Thanks mekanix, as always you have an answer. I'm thinking of doing a semi custom harness to clean it up a bit, new connections and what not.

How goes the arduino project on your bike mekanix?

[Guest]

Stalled for the monent.
I have that bike to tune. The other one to reasemble and a Seadoo that is nearly finished along with mvi's for two vehicle's. ue and the weather sucks :-p

I've been thinking of different things to add but I need more components. All the stuff I want to put on he bike I also want to experiment with on the bench but I only have one of each.

[phillipjohnw]

Seadoo? Nice! I have a honda f-12 jetski myself.

Ran into another snag today. When I started this I had to replace the rear sprocket and now the chain is too tight, like doesn't fit tight.

Anyone got any suggestions for a decent chain?

[Guest]

Cool, I'm nearly finished it. Just rebuilt the engine from the ground up.

An x ring chain is about $100 but treat it right and it will last a long time. That's all I use now.

[phillipjohnw]

Hey Mekanix, do you happen to remember if the 450 chain is 520 or 530? I've been searching through my clymers and it doesn't say anywhere. I've looked on the web, but I am getting mixed results.
