My blog of a Jetmax 250

[WirralGhostHunter]

I will start my life with the Jetmax here. I will post thoughts, likes and concerns.
This is day three with my new scoot, and this morning it went in for its first service.
Yesterday I let it run until the fuel warning started to flash, so I promptly went to fill up, low and behold it took 8.5 litres, so I assume there is still 4 litres left when the warning shows. I will try this again soon to see if it is a constant reading. I have set up a "Fuelly" account to monitor mileage returns, and I will try and keep up with entries, here's the link for anyone who may be interested.

Today I noticed the bolt that hold the front wheel has thread protruding from the right hand side, should there be a nut here or is it the way its supposed to be?

Also in my documentation it doesn't say that I have adjustable rear shocks, but it looks to me as they may be adjustable, if this is the case, anyone know what they are set to or how to adjust. I would like to firm up the back end, well possibly the front too if its possible. Well thats it for now

Oh my... Perhaps scooters, unlike all the normal motorcycles, don't have nuts on front wheel axle, but I would put one and a washer too.

As much can I see from the photograph, it is possible to adjust spring preload on the rear shock absorber.

The front axle does protrude the side of the fork as shown in your photo, and no it does not require a nut to secure it. I think you will find if you look at the fork leg (opposite side) you will notice that there are two smaller bolts that have Allen heads, which are used to secure the axle in place. Simple design and one found on some motorcycles as well. There is a similar set up to this on my 2007 Yamaha Dragstar XV1100A Classic - it's not exactly the same design but the principle is there. So no worries there.

As for your shocks, yes they are adjustable for preload. You should find the adjustment spanner in the tool kit. Using that tool, you place one end into a slot near the adjustment collar with the stepped graduations, to either turn one way (by pulling the collar using the spanner as a lever) to compress the spring and therefore make the shock spring shorter and thereby stiffen the compression (preload) or the opposite way to make the spring longer for the opposite affect.

Hope my explanation without pictures makes sense.

I'd ask your dealer or wherever you have the bike serviced to check all the bolts and screws (e.g. all the screws for attaching the plastics etc) for tightness. I prefer to do this myself, as it's a good way to learn where everything is on a bike, so that you can be prepared in the event of a failure or whatever.

Thanks for that bikerdoc, its put my mind at ease

Yes made sense, I didn't have a spanner to fit in my toolkit, but I used the allen key and viola, sorted

I think I will have a go myself, but at the next service I'll get the mechanics to check aswell....

Shock absorber update, I took the adjustment up 3 clicks, and it has improved my ride (it was set to the softest setting- like riding a bouncy castle). I may take it right up an see how it is. Probably on the cards is a shock upgrade to a decent set..
Noticed today that the left front indicator has water in it (it hasn't stopped raining here). I will have to remove and check it out, Hopefully just an ill fitting boot, will keep you all posted. Overall still very very happy with the sccot

Did you manage to adjust preload with bare hands and with a little Greco Roman wrestling with a scooter, or you have found the right tool? Allen key and viola - somehow I can't imagine... :)

Thanks for the reply Zorge..
