Citycom 300 / Re: Way to higher the passenger pegs?
« on: May 16, 2015, 03:18:41 AM »
I would like higher pegs for my wife but it seems hard to do.

To keep the current pegs, I figured I'd need to either weld new mounts or make an extension bracket. They'd have to be strong enough to take her weight as she pushed down to get on the back too.

The other option is to get some suitable rear pegs and mounts from a dirt bike or sports bike or.....similar, and bolt them on to the frame.

Either way, not easy, so I didn't try and now my wife is used to the stretch.

I haven't tried so I'm afraid I don't know. You can download the manual here


Some good news if you are interested in moderate tuning made easy - I found some thermistors that have almost the exact same resistance profile as the one fitted to the Citycom, except the ones I bought have too low a value by about 40%. So the best parts are the same but between a 2K R and 2.5 K R value at 21 degC.

The ones I bought are Vishay NTCLE100E3152JB0 and there's an Ebay seller with 12 for US$5 incl shipping.

The ones I bought (1.5K R) are fine for warmer climates and add 4% extra fuel. If you get the 2K, they'll add about 7%. 

If anyone is going to do this, let me know, and I can post clearer instructions.

Here is a pic of the measured values of the SYM TA sensor and the Vishay.

Which do you prefer so far ? Diablos or City Grips? I guess the Citys if you don't like the quick turn in? If they have a sharper profile, did the rear Diablo square off a lot?

Fuel pump relay has two red/yellow, one orange/white and one black/purple according to the wiring diagram on page 270, and I don't see any other component using purple, so I guess it is the fuel pump relay, shown on page 51. It should be mounted on the frame just forward of the mount for the passenger footpeg.

Good news - sounds like you found your problem!

It could be the power relay connected to the battery (page 54 of the manual) ? What colour are the wires? Page 240 has a general location of electrical parts.

So the Michelin have a smaller circumference than the maxxis? That's a shame.

Where are you sourcing your Dr Pulleyparts ? Now I've tuned the engine, I reckon I could go for 20g or heavier weights, but I can't find anyone locally with stock. I saw Kiwiscoot used 25mm diameter, 20mm wide Dr Pulleys and 19g, and he was happy.

I was tempted to get the organics - half the price and less disk wear - but I wanted to get HH for the extra braking force - my front brake was dismal and I wondered if needed something more than pads to get it doing its job. But, thankfully, the HH have shown that new pads are all it takes.

How much is the Brembo disk ? The SYM dealer here charges US$108 for the OEM part.

I got some from that seller and they arrived this morning. The fitted exactly right and bedded in 30kms of town riding, and wow, what a difference. My Citycom has a decent front brake - there's bite for little dabs, and decent stopping power too. They might even get a little powerful as they fully bed in, but since my disks are very smooth, I think they are likely already as good as they'll get. If anyone has any experience of bedding in these fellas, let me know.

Anyway, I expect I'll have to give the front some respect in the wet from now on. Odo says 7,900 so I'll keep an eye on disk and pad wear and update in due course.


Quick update - I've been doing more in-town riding so fuel consumption is now around 32.5km/l - and I pulled the plug and the fuel ring is now half way round. I have just switched to a colder plug to get it to colour more - CR9EIX - but here is the CR8EIX after about 1,600kms.

Another way to do this is to identify all the components on the circuit and disconnect them all, then use the connectors as a way to test a short to ground on every connection.

It's a bugger eh.

Citycom 300 / Re: Rear wheel removal and the rear "fork".
« on: May 03, 2015, 06:40:12 PM »
You might not want to know this but I took the rear wheel off mine to remove rust on the starter motor and the flaky paint on the transmission unit and it was easy. My rear wheel wouldn't budge at first but one tap with a rubber mallet and it slid off easily. I cleaned off the grease and applied fresh grease so I hope next it will do the same. I guess you were unlucky that the previous owner hasn't been re-greasing the splines?

Anyway job done?

Ug, pushing a machine... but well done for getting her home.

You've likely got a worn, stretched or damaged cable on that circuit and it is creating a short. So, you'll need to get the fairing off and physically examine the loom, especially anywhere it is contact with the frame. Look for where the cable has rubbed the paint off the frame and the insulation off the cable. Look for snips, crimps, loose insulation, anything letting metal contact metal.The ECU is at the rear nearside and it's on the same circuit.

This can take a long time so I'd call the repair shop to find out if they will do this and what they say about finding shorts. It can take a long time so it can be expensive to pay someone to do it.

Good luck.
