New member here, just wanted to say hi. Picked up a 2006 Piaggio Typhoon 50 last month with 6800km on it. It's in great shape but looking to do a few things to it over the winter.

1) Remove "Typhoon" badging on the side
2) Source non North American signal lights as the ones we get are HUGE and take away from the look
3) Fix the charging system. Battery is ok but not getting above 13 V when reving.
4) Replace stock tires, thinking Pirelli SL26
5) Brake system maintenance, flush fluid, replace front pads and rear shoes


Since my wife will be using it mostly I want it safe first, then I'll get into modding it for performance. Definitely a pipe, upjet and variator tuning. Maybe 70cc kit after that.

Cheers,
Lewis

welcome... i have an ET2 which shares many of the same components....if you have troubles, let me know


i see you have one of those hitch mounted bike carriers...do you transport the typhoon with it? is it sturdy enough for long trips?

It works really well. I hauled it back home from where I bought it ~700km through the mountains. The ramp part works great for loading and unloading as well.


Loaded up for the drive home.

Slowly modding
Figured I'd use this to keep track of my modding progress so will be a bit of a "build" thread.

There isn't much info on North American model Typhoons as they were only offered here for 2 years so hopefully some photo documentation will help others.

Tach install
Remove warning label stickers and "TYPHOON" lettering
Install new stator - halfway
Brake pads and fluid flush - have parts
Euro spec signals and LED conversion - have parts


Had to get rid of the "Typhoon" lettering and clean it up.


Tach/hour meter installed. Had to extend the wires to reach the spark plug wire.


Next was new Stator install. Diagnostic process led me to bad stator.


Got the exhaust off. What a pain as you have to reach the right side nut from the front after removing the panel.


Exhaust had to go to get the fan shroud off. Getting closer.


Here's where I realized I wouldn't be able to use the 3 leg puller I had borrowed as you can't get behind the flywheel from the sides.


Warning labels and lettering removed.

Greetings:

Nice work so far. To remove the flywheel, you can use a harmonic balancer puller or even a steering wheel puller if you thread into the flywheel's M6 holes. I'll try to find a pic to illustrate. Just make sure you don't thread in too far and further damage your stator. Most stator damage I've seen is due to this, but I guess yours is roasted anyway.

Greetings;

I have one similar to this one from Harbor Freight: Stand by, trouble with the URL Similar to THIS ONE.

BTW I've owned several sets of Pirelli SL26s. They're OK and very affordable, but I now have Metzler ME1s and am happier with the grip and with long-wearing. Of course in Calgary you'll need to put studs on them very soon...

Thanks for the advice. I have a line on one of those pullers so will try that. Also thanks for note about the tires. I've ran Metzlers on my motorcycles before with good success so that might be the way to go on the scoot too.

Hi and welcome!

The shipping calculator on Scooterpartsco is based on UPS and gives bogus (really high) numbers to Canada. I'm in Toronto and have ordered from them a number of times. In my order notes, I request they ship USPS (not UPS). They charge actual shipping cost and refund the difference from the original (really high) amount the site charged.

They're pretty responsive by email, so you can drop them a note to verify what actual shipping would be in your case.

i wouldnt waste your time with a pipe or variator, mine went dog slow with both, youd be better doing the 70 kit, jets and airfilter to start with.
is the front light stock ? over here (uk) it was a single lense that was about as useful as a candle

Thanks for the advice on upgrades. The headlight is the stock North American version so projector style low (35W H8) and high (55W H3). Pretty decent lighting for a scooter.

Road Block #2
So got the puller tool and successfully removed flywheel. Yay small win.

Quickly discovered the factory stator doesn't have a connector within ~3" like the new one I purchased did. (see pics). As near as I can tell the wiring goes to the CDI box (red, white, green) and to a harness (grey, blue, yellow, green) that's below regulator.

The other real pain is that the starter motor wires are in the same wiring sheath (see pick from rear wheel angle).

So I'm guessing the OEM stator has these really long leads that terminate in a Red/Green/White CDI connector and a Green/Blue/Grey/Yellow connector. These would have to be like 18-24" long wire leads which I haven't seen on any stators.

Any insight would help. I was hoping for just a plug and play but now looks like I may have to cut/splice wires from old stator which I really don't want to do.

Thanks.


Ok got access this should be easy.


Wait..where's the connector?


Comparing new and old


The connections from stator I traced back (yellow is CDI and red is up to regulator/rectifier)


Here is the connector I circled in red leading from stator up to regulator/rectifier.

Found the problem
So with some more digging and searching I have found that I did indeed order the wrong part and found what I needed. Hoping I can return the wrong one, if not if someone needs one I will give a good deal just PM me.

It seems to be a problem with the North American versions of the Typhoon 50 as the years don't seem to line up with what comes up on parts sights. The part I need gets filtered out when I select my model and year on multiple sites.


So the one on the right is what comes up when searching by model and year. The one on the left is what I actually need. Doh...

Frustration setting in...
So was able to swap out the stator and was getting proper AC voltages (unregulated output) so thought my troubles were behind me. Nope, still only ~12.6V at battery up to 5000rpm. When not running battery is at 12.5V.

So I ordered a new regulator. Swapped that in this morning and no change.

Thought I'd try a different battery from another bike and same readings. Also used a second multimeter.

I'm not sure what else to check. Could I be getting a voltage drop from regulator wiring to battery?

Thanks in advance for any help.


New stator on


Made a tool to hold flywheel.


New regulator on right.

FWIW I had voltage problems on a Buddy 50 that I was POSITIVE was a bad stator...after swapping in a new regulator (cheap), CDI (cheap), and stator (more expensive), the issue turned out to be a sketchy/loose ground connection.

Maybe try measuring the voltage one component at a time back from the stator and see where the drop is taking place?

So I've continued testing and all grounds back to battery negative pass continuity tests.

I did tests 1-3 as stated in the tech manuals and 1&2 passed with the full 30v AC.

Test #3 however seems to be where my problems lie. On startup idle was at 1100rpm and amperage of 1.2 amps. When I increase rpm to 2000 the amperage drops down to 0.3 amps. If I continue to increase RPM the amps keeps dropping.

This is with the new regulator as well.

Thoughts?


Conducted these tests. Note amperage test failed.

My interpretation: test #3 at low RPM confirms that the battery is providing sufficient current when the stator is not generating much. As you increase the RPM, which - note - is not part of the test, the current from the battery decreases because the stator is producing more juice/higher voltage. (Actually at high RPM, the current should be going into the battery until it's fully charged.)

I think the takeaway here is that nothing is wrong with the stator.

I'm concerned that the stated amperage specs should be 1.5-2.0 amps @ 2000rpm. Mine is only 0.3 amps @ 2000 rpm so well below the range.

Voltage at battery is still only 12.3v at 2000 rpm (specs are 13.5-14.5v @ 2000rpm)

Something still not right as it isn't charging the battery.

Hmmm. 1100rpm would be a low idle. What tachometer are you using and is it set for a 2 stroke engine?

That was on initial startup. Once warm it idles at 1800-2000 rpm and the tachometer is set for single cylinder 2 stroke so not concerned about that.

I reran the tests once it was warmed up and idling at 2000rpm and had same results.

I did but would like some input. I tested continuity from the negative battery terminal to the 4 ground points I could find and they all showed good continuity.

3 of them at the regulator mounting bolts (2 on one side and 1 on the other)
1 at the Coil

See pics. Are there any other points I'm missing?

Unfortunately I can't find an accurate wiring diagram for the North American model Typhoon 50 (2006/07). The one listed on this site's downloads (from the Haynes manual which I have as well) is for the 5 pin regulator, the ET2 later model is the closest but the wire colors and the light set up is slightly different for NA.


3 ground connections here, 2 on right, 1 on left of regulator/rectifier.


Single ground connection here

At the very least you are to be complimented on your methodical testing and clear explanations. I'm grasping at straws here...

What's the maximum resistance that you measure between ANY of the ground points you can find, and the battery ground? Perhaps there's a break in a wire that you can't see.

Is it possible that one of the fuses (especially that 7.5A main fuse) is partially blown or poorly-connected?

Is it possible that you're using the wrong model regulator or CDI?

did you measure the gap on the hall (ardunio) sensor?..you might just need to adjust that gap.... i cant find the literature that gives the gap range but you might already know it....let me know if you need me to help you find that setting

if your rectifier and stator are known good ...and the battery is capable of holding a charge higher than 12.6....

im just guessing here...but what happens if you disconnect your headlight or pull the fuse? ...it almost seems like you are getting a power draw thats increasing as rpms increase.....perhaps a bad wire somewhere or, as my mother would say "something is shoveling out faster with a spoon than I can bring in with a spade"

Ok more troubleshooting tonight.

Checked hall sensor gap and it's right at 0.8mm.

Wanted to confirm battery still ok and taking charge, so checked voltage when on trickle charge and it started at 12.3v and came up to 13.7v in about 5 min so looks like it's still ok.

Checked continuity of wires between stator and regulator (blue/grey and yellow) and both show continuity and no resistance.

Checked continuity of wire between stator and fuse (blue wire) and from fuse to battery (red wire), both show continuity and no resistance.

Checked continuity and resistance of stator wires green and blue/grey and both show continuity to ground with zero resistance.

Started it up and voltage still ~12.3 at 2000rpm idle.
-Unplugged headlight, no change in voltage.
-Unplug starter relay to isolate, no change in voltage.

Still happy to keep trying things so keep any ideas coming.


After a couple minutes on trickle charger

Since you said you swapped out the battery with no change in symptom, this probably isn't the issue, but the way you check a battery is not how fast it comes up to full charging voltage, but what it stays at after a few hours off the charger. It is possible for a failed cell to come up to voltage without having any capacity, so a wait without the charger attached is an easy way to identify it.

Thanks Juan. I will check that after I take it off the charger. Will report back on voltages I see.

What are you getting for DC voltage at the regulator/ rectifier?

Ok so had the battery on the tender overnight and then took these readings throughout the day:

11:55am - 13.26v
12:15pm - 13.2v
1:15pm- 13.1v
3:20pm - 13.0v
9:00pm - 12.85v

Ignition switched on - dropped down to 12.15v after 1 min and stayed there

Brake on - 11.96v

Start bike - 12.2v idle at ~1800rpm

Yellow wire out of regulator 13.5v @ 2000rpm, 14.5v at 3000rpm

Ignition off 12.5v

As per above:
Yellow wire out of regulator 13.5v @ 2000rpm, 14.5v at 3000rpm

Pulled fuse and tested stator side (blue wire) and only saw 5.5v at 2000 rpm and it dropped to ~3v at 3000 rpm. Checked voltage at stator connector and yellow wire was the same as at regulator pin 8 noted above, but blue wire was at 12.5v. Looks like a voltage drop in the harness?


So if I'm getting good voltage readings out of regulator it must be the battery correct? The yellow wire goes back through the stator coils then to the fuse via the blue wire. Before I grab a new battery is there somewhere else could be losing voltage or does the above make it clear it's a battery issue?


Getting 13.5-14.5V from 2000-3000rpm at the yellow wire pin#8.

Any input based on the testing I noted above?

Is my battery pooched and causing some of the wonky readings?

im thinking something might be up with the battery....

at the same time i dont understand the sudden drop when you turn on the ignition....its like you just dropped a full volt...

I thought you had said you previously tested with another known good battery, and behavior was the same?
