Hello guys i have just joined here, ok, if anyone can help or tell me whats wrong or missing.. I have PGO gmax 50cc 07 reg, had it almost ten years, i got it at 6 months old, never had any issue really, until now, ive just come to replace the front shock gaiters, took it all apart, and on reassembly, the front wheel with speedo drive etc there is a gap there is a spacer on the disc side, im sure i haven't lost anything as i made sure i didn't, Ive had the front wheel off before for a tyre and i never noticed.. So basically when tightening the nut up it ends up squeezing the bottom of the shocks in about 8mm and i think it has always been like this, as the feel of pushing down on the front end is how its always felt, so i backed off the nut and left everything relax and the suspension is nice and soft, and its never been like that.. ive measured between the forks and they are pretty much parallel all the way down give or take a mm or 2 As it is, Its spindle through one fork then a spacer then the wheel then speedo drive then other fork leg, but there is a gap unless you squeeze up the bottom legs, cant be right, or is it? My question is what is missing, as the speedo drive side needs to be right up against the fork to stop it rotating with the wheel, and the other side has the disc and spacer, i dont know have i got a wrong speedo drive, is mine too thin? Is something missing between speedo drive and wheel??? I have never seen another pgo gmax to be able to check it out.. the gap in the pics is me just moving the speedo drive by hand as its loose, unless you tighten the spindle nut up but that forces the forks in.. Anyway thanks for looking and sorry for the long post, and some pics..
Here you go: https://www.ajsutton.co.uk/genuinep...50-2005-2008/tire-frt-wheel-frt-caliper?uID=0 The only spacer is on the disc side. It's not unusual to have a small gap on one side of the wheel until it's all tightened up. As long as the front moves as it should, the wheel turns freely, the brakes work and the suspension works, should be just fine.
This shows you how to check wheel alignment. Obviously this is a bike and the fact that the rear wheel is adjustable can lead to misalignment. On a scooter the wheels are fixed so it should be easier to check the alignment. You can use a long straight edge eg plank sitting on bricks or similar. Same with the string if you align the rear wheel so that the string is just touching both sidewalls of the rear tyre then trap it between a stack of bricks at the front,with the string taut, you should be able to see if there is much difference in the gaps at the front. Put the wheel up against the speedo drive side and then check alignment. If there is a bigger gap one side and moving the wheel over solves it possibly releasing the pinch bolts at the top of each fork then tightening up the spindle before re tightening the pinch bolts might help? As said there should be a small gap otherwise it would be difficult to get the wheel back in. http://www.motorcyclistonline.com/simple-motorcycle-wheel-alignment#page-8
Hi guys thanks for the replies, ok just had it all apart the forks are parallel, i tried various washers etc to space things but no, this is a vid of the gap, this is without putting the nut on as it properly crushes the fork legs in...maybe its always been like this, but seems wrong this, its like the wheel is too thin?.. also trying to press the forks in by hand is impossible they are solid, but the nut on the spindle can wind them in, must be wrong that, as the suspension is dead stiff like that and nice and soft and smooth when nut not tightened up.. any help guys thanks rik
Are the wheels in line when the speedo drive side is closed up? If so I'd look for a spacer. Take the spindle size and look for a spacer that totals the original spacer + the gap. Washers will work if put between the spacer and fork leg. That gap is a bit large so it's just possible it has the wrong spacer. Only real way to prove it would be if someone with the same machine measures theirs or possibly a dealer? As long as you are happy with wheel alignment when the wheel is hard against the speedo drive side and the brake lines up.
Ask these to measure it for you? http://www.ebay.co.uk/itm/Pgo-gmax-...770911?hash=item235807f15f:g:TWAAAOSwT6pV5u0M
Hey thanks for the reply, i just bought some plastic panels off that person on ebay, ye i might ask them.. If i put washers on the disc side to take up the slack on the speedo side, the brake caliper dosent fit, and when i put washers on the speedo side the speedo drive dosent lock in the fork part...Like ive said it might of always been like this from i got it cheap at 6months maybe it was bodged together?
I know this is an old thread and you have probably sorted it by now but I've just had exactly the same problem on a Gilera DNA. I took the forks apart to clean it all up and repaint the sliders. I had quite a large gap on the speedo drive side but there was only one spacer on the disc side when I dismantled it. The problem turned out to be the fork legs. I inserted the spindle and loosened off the clamps on the yokes. Then by turning the fork tubes I discovered they would move in or out depending on the positions. I can only assume they adopt a slightly curved position so if removing the fork tubes you may have to do the same or mark them so that they go back in the same position. They are not damaged in any way.
Hello hey thanks for this info, i haven't sorted it actually, i will now look into this over the weekend thanks alot.. rik
Try it with the wheel loosely fitted and twist the speedo side leg first and watch for any inward movement until you get the max and if it's still not enough tighten that one up and try the brake side.
Ok i tried this mate but nope, dosent work on mine, thanks though. Nothing changes when turning them..
Oh well worth a try. Your pics are a spitting image of mine and my speedo drive didn't engage with the notch and the gap was exactly the same as yours.
