This week? Can't wait! You have to get video!

As for the ignition... yeah good question, the 500 is more advanced at lower rev's though right? Might be a better option on the hotted up motor... although I can't say as I'm all that flash on why more advanced would be better in that regard...

Seems like the opposite would be true to avoid detonation at low RPMs.

Try them both and see?

Does the 500 use a mechanical advance unit like the 450? Think the 500, or at least some models thereof, have the advance curve built into the ignitor. Don't mix and match.

450 and 400 are mechanical. The 500 os digital and advances later.

Its just a mater of 5 minutes to put the other rotor and plate in or a couple hours to make new connectors up the way I want it.

I might just put the other plate in and mod later. I just want to hear it run.

I just want to hear it run.

Me too!

I have a Bob B ignition advancer on my GS500.It advances the ignition 5 degrees more than stock.Works great.Pre 01 GS these work on.Post 01 have a single ignition and a throttle position sensor to control ignition timing.From my understanding,they can't be advanced mechanically with running into ridability issues.

I reinstalled the stock advancer and pickup plate. I'm going to make a good wiring harness for the other one. I'd like to keep all the parts as a replaceable assembly with their original connectors and just add those connectors to the bike and keep the original's. That way I have the option of using either one. Just have to rip the spare harness apart, which I hate doing because Its complete and in good shape...

With the original I can easily get 5 degrees advance and change the springs to change when it advances. I loose all that with the 500's ignition. But the 500's parts are much easier to come by.

Sounds raunchy
Good raunchy
You gonna put some mufflers on there?

[ben2go]

Oh yeah.Mufflers help.LOL

[Guest]

Yeah I have them, just couldn't wait though

Ran like crap at first so I put 150 mains in. That made a huge difference and there's throttle response now. That might be too much but id rather find out its rich than lean. I ran it for all of two minutes just to set the screws a bit for a better idle.
Thing sounds like a sewing machine though, I'm going to have to adjust the valves to quiet it down.

What should I set the valves to ? I thought I did pretty good setting them the first time. The right side sounds ok... or as expected. The left side is louder.

How long and what RPM for cam break-in?

What about heat cycling and re-torquing the head ?

How should I set the APE cam chain tensioner?

I can't remember this stuff. I'm sure Ray told me a while ago :P


117.5 main jets feel way too small, There was no throttle response at all.
150's seem to work ok, It will respond to throttle but I can't really tell for sure yet because I don't want to rev it.

Engine seems well balanced at low rpm, no vibration at all. Even smoother than stock was.
Starts at first crank ( if my battery will do it) There is definitely more load on the starter to turn it over.

Wow. That thing sounded sweet. Very...Hot Rod like. It's kinda strange to have that hot of a motor in a laid back half liter cruiser. The ultimate sleeper bike maybe?

[ben2go]

.03-.08mm and most of us set the exhaust to .08 to .12mm.the exhaust have a habit of receding into the head if the engine is run hard and lean conditions seem to make it worse.With the .08-.12mm settings,I expect to get around 8000 miles before having to change shims again.

I know what happened. I used 3-8 thou. That's supposed to be 1 to 3 thou. My feeler gauges are hard to read. And at 4am I must have just been too tired.
