My blog of a Jetmax 250

No, since the tranny case is just that a case so it's dry inside, and simply houses the variator, belt, rear drive pulley and clutch shoes etc. no gasket needed, unlike the transmission itself which is the oil you are looking to change. I've updated my last post (page 2 of this thread) but forgot to mention its a good time to clean the tranny filter while its off...

I thought it might be something that keeps belt and pulleys dry.

[bikerdoc]

no worries, it doesn't appear to suffer any moisture issues, unless an unscheduled dip were to happen. Are you planning to take the tranny case off? If so then I might put together a photo array of what is involved to help you through it, otherwise I think the steps I outlined should guide you (and others)... I know that the tranny casing was difficult the first time to remove and that applied to both mine and friends Jetmax. The subsequent times the tranny case was removed thereafter - no such difficulty!

Thanks for your post bikerdoc, it has given me the motivation to have another go. I have ordered an electric impact wrench, as renting one is not worthwhile (I plan to delve into the case to keep it maintained). Hey if you have a photo sequence of any jobs you carry out, I am sure it will be of great use, not only to myself, but all Jetmax owners. Keep up the great work.

Time to re-seal the headlight & indicator lens plus swap out the standard halogens for xenon ones.
I really wasn't looking forward to taking the front of the scoot off again, but I had my new xenon bulbs waiting for over a week on my desk. So I nipped out and purchased a new tube of clear silicone. I was hoping that it was sorted last time, but the amount of water inside was amazing, I'm still not too sure how it gets in, this is both the headlight and indicator enclosures (left side).
From the pic you should make out the water droplets, I initially thought this was on the outside - but oh no! - on the inside...... STRANGE....
On closer inspection I think it is entering along the edge of the lens where it meets the case (see pics).
I dont want to do this again, so the silicone went on, right around both of the culprits - LIBERALLY.........
OK so the left side went back on, the smell of silicone nearly knocking me out, and off comes the right hand side (to swap the bulb).
Grrrr, the clip that holds the lamp in is fouling the outer case - can unclip it - but not lift up...
Grrrrrrr, take out the little screw - drop it on the ground - ten minutes to find it Grrrrrrrrrrrrrrrrrrrrrr......
Bulb in - clip back - panel back on.
Very happy with the bright white light these little suckers give out.
Now to see if the headlight is waterproof. Wont be long as it hasn't stopped raining.

It seems that you have not spent much time in the kitchen adding vinegar to the salad, because the smell of acetic acid from silicone overwhelm you.

These bulbs will become xenons about the same time when I become slim and blond, namely - never.

I thought they were actually brighter than normal, but my experience has shown that they not and their bluish light tiring eyes. Instead, I would look for an ordinary, but good quality halogen light bulb, from Philips, Osram, Beru or Narva.

eek! So I take it these aren't xenons
I did try them out for a night ride and they were a great improvement on the original halogens. They actually produced a bright white light instead of the yellowish before, and lit up the road brilliantly. I didn't notice any blue tint to the beams, I'll follow a friend and see if the light appears bluish to him.
How long they will last? Hmmmmm. Report to follow...

Hi WirralGhostHunter, I have just replaced my 35 watt halogens with 55 watt globes on my Jetmax and I notice the lens gets rather hot. I did not feel the lens with the lower wattage in so I can't compare. I am a bit concerned about the reflector etc being damaged . Can anyone let me know. Regards

You've probably heard of something called Murphy's Law ...

Hi ethron, I think I recall bikerdoc doing a similar mod before he went the HID route, and he commented on the wiring getting rather warm, I always refer to his posts before I tackle anything (he's virtually taken his Jetmax apart, so he knows it quite intimately. Because of the crazy laws in the UK, I couldn't chance swapping out for HID's, but I did find some alternatives lamps ( I posted them here ). These give a really bright white light compared the the standard yellow light. Although not HID's, they do a really good job. Perhaps I will try and make a night video to show how the perform....
