Turns out it was seized so some assertive hammering has done the job!

Hi, Just a quick one, When removing the rear wheel of the bike, am i doing it right by trying to remove the axle rod? because that's how i do it on all my other bikes but yet so far i seem to be knocking the bearing out at the same time? Could this be because the axle rod is seized to the inside sleeve of the bearings? Thanks

The place where i got the sprocket from have only a larger tooth sprocket in stock, so it would mean i would have to wait for then to get a new one in and frankly i am impatient and cannot be fussed to wait. I will soften the steel then drill+tap it and then harded it again. if it goes tits up, I shall just get the correct size sprocket and learn a lesson .

Right it turns out that the locking washer and the old sprocket that was on my bike originally was 28mm which is for bikes upto 2006, so what has probably happened is my bike was built pre 2008 (as the number plate says) but was registered in 2008 so the parts on the bike are actually pre 2006. So what i have decided to do is drill out two new holes and then tap them to the right size.

Its an after market afam sprocket set (I was told they are a good make). Yes it the locking washer. and one did not come with the new set so I need to use the old one. If i cannot get the old one to fit and cannot find a new one anywhere, does anyone know of a place where i can get a correct size one machined up?

Hi, I just bought some standard size front and rear sprockets plus chain to go onto my gilera rcr 50 as the old ones were worn. However when I came to fit the front one, I encountered some issues. The washer that goes onto the castellated/corrugated drive knob (sorry I dont know the real name) after the sprocket, has the holes in the wrong place - on the sprocket that i took off, there were 4 threaded holes which the washer thing's two holes lined up with. The new sprocket has only two holes and they are approximately 2mm closer into the centre. I shall upload some pictures to so that you can understand me clearer (I realise that my explanation is difficult to understand!). I've looked for new washers however i cannot find any. Anyone have any ideas on what i should do? Thanks, Jasper

Hi, I just had my bike MOTed and to my surprise it passed! I was advised to get a new chain and sprocket as the chain is slightly worn and the sprockets are "hooked" (not a great deal but enough for an advisory) so i am basically wondering firstly what size is best for a 50cc as i know different sprockets effect the speed/acceleration - as the bike has a history of over heating I'd prefer acceleration over top speed as i assume faster = hotter (correct me if thats incorrect). Secondly what make is a good make. The bike is a gilera rcr 50 which has the same dimensions in the sprocket department as the derbi senda 50 and the aprilla rx 50. Thanks I'd be greatful of your advice! Jasper

oh thats annoying! but surly if its been restricted post manufacture then wouldn't that mean it was designed to go a speed pre-restriction that is faster than the current speed??

Oh, so would it need to be upjetted or perhaps a de-resticted exhaust? Well I would like it to go faster because it takes me almost the same time to ride from A to B as it does to cycle!

Right so if its restricted, what is it that I would have to do to derestrict it? yeah I've tried both of those places and no luck .

Hello, I bought another bike a few weeks back as a back up bike to my notoriously unreliable Gilera. I saw it on ebay and bought it because it looks hilarious! Unfortunately its very slow... As in it struggles to go thirty! So I was wandering whether it may be restricted some how? also, has anyone ever come across one of these before? Its in very good condition, it only has 4000 miles on the clock plus all the relevant paperwork - how much do you reckon its worth? I want to know whether i got ripped off (not that I care - bike is quite amusing so it would make up for over paying!) or whether I got a bargain. Also, does anyone know of a place where I could get parts for this bike? Thanks! Jasper

Haha its tempting!

Back of a van .

Okay thanks everyone, Ben you cleared that up nicely. Its worth fitting some rear indicators on then - by the way, front ones flash perfectly normal . Oh and one more question with the MOT's. does the test involve driving the bike? its just i recently fitted a new piston and the bike needs tuning correctly before its ridden properly so that hopefully it wont hole its self again.

Point Blank, that did help thank you. Currently I have front indicators that work but both the rear indicators have been kicked off, so are non existent. Could you just further clarify that please. The only reason I am wanted the bike to go in and pass first time is its a two week waiting list so the chances of me getting a retest soon after its first tested is slim. Thanks again.
