Can I ask what is the benefit of using a larger carb? Surely the cylinder can only take in a certain volume of fuel air and so how does increasing...
Hi I know that asking this question on a scooter forum may be foolish and I’ll get one sided answers but here goes: I previously rode scooters...
Doesn't sound normal to me. Will get hot quickly but not so it glows red?! Have you made any changes like removing baffles, check coolant and oil...
If you have sufficient access then I would first try to use a Dremel type tool with a cutting blade to cut a deep groove across the head which...
Fuel mix sounds wrong. Run the engine until warm then tune the carb to its peak. Have you got a manual or auto choke? If the choke is faulty then...
Clutch springs don't help with acceleration, they engage at different rpms to allow a better initial pull away. Your scooter needs to nearly reach...
My first check would be the rollers in the variator. If you fit lighter rollers then you will see an increase in rpm allowing the bike to reach...
Do you mean changed or charged battery? If changed then is it the same spec? I would start by running a volt meter across the fuse box...
Looks like the bottom end covers the square bottom of the sanctions to protect the axle nut from dirt and keep it in place. You may find that a...
Did you sort this problem out? The reason it runs on the stand and not the ground is because it’s not under any load so it’s takes no effort for...
Off road, got a puncture, middle of nowhere so I cut a slit in the tyre and filled & packed the whole tyre with soil then wrapped tape round the...

As previously mentioned it is time to learn about the transmission. If the variator rollers are worn or sticking or the variator itself is...
Fibreglass the inside for strength then once it’s hardened use fine filler on the outside crack. Prime, spray or put graphics over it.
Check the choke is working properly then retune the carburettor. Let us know how that goes
The problem with people fiddling with add ins is that a lot of youngsters just throw on big carbs, open air filters and expect the bike to whizz...
When you say that you are using spark plugs up then what do you mean? It sounds like you are running rich which is causing your plugs to foul with...
No but I think I’ve worked it out. It looks similar to a cg125 where you remove the whole clutch cover and a small flat filter sits at the bottom...
hi servicing my WK zs125 bike but can’t find an oil filter? There does not appear to be any cylinder pod filter and I can’t see where a thimble...
Spraying will only look tacky if done poorly. Look at some pictures of similar bikes and get a good idea what you like. Rub the panels down to...
