Hi where should i put the coolant in the little bucket on the left side or directly into the radiator? On my bike the bucket is empty but doesnt rise above 4 bars of temp and also what color of coolant is recommended for this bikes? Thanks in advance
Fill in the radiator cap and run until it's full the bleed nipple is under the tank also you need to use the red coolant. Hope this helps. Top up the tank with the low high after the system has been bleed..👍
Yes it has always done it from new my son has same bike and his does too it’s a common fault/nuance with this engine. But normal nothing to worry about 👍 I even changed the engine after this video for a low mileage 2019 mx125 and that rattles with lever out in neutral
@@BigBoyzToyz1974 thanks for the reply I changed the clutch plates in my 2016 rs4 and i still have the same rattling noise so was just worried it could be something more serious:)
@@TSync41 no mate it’s fine it’s the thrust bearing they rattle when the clutch is pulled because there is no load on it but once in gear and riding it will be fine another thing it does is whine when changing down and using engine breaking but it’s just the quirks of this particular engine 👍
Hey mate, got one of these the other day, it seems to be having an issue with clutch not fully disengaging or engaging. I'm currently messing around trying to adjust the cable hoping that is the case as opposed to clutch damage. Can't push the bike back when clutch is pulled in and in gear. Tried warming oil. Problem doesn't get much better. Also jolty when coming off the clutch. Got any ideas? Thanks
Have you changed the oil it needs to be changed every 6 months if you can I highly recommend using Motul 300v 5w40 if left standing for more than 6 months moisture will build up in the crank case it only holds just over 1ltr of oil so be a cheap thing to change..I would start there first..👍
Hello, I'm still new with the RS4 bike and engine and do want to learn all about it! Sometimes my bike makes it hard to downshift, you really have to give it a kick, you know what the problem could be? And also, the clutch on my rs4 is harder than the other bikes ive tried, is it just normal or is there something avout the clutch i need to change? Thank you
It’s a common problem with some the selector spring can snap easy job to do but hard to get the part. Go on a Rs4 forum there will be others with this issue.
Yes you can but not derbi clutch basket the rear sprocket is bigger..also make sure its derbies gpr 4t not 2t I know its obvious but some don't distinguish on advert.
Hi @BigBoyzToyz.I have a problem with a aprilia rs4 125 2012,on the left side as you look from the back ,where the shifter is located,it leaks oil,in 2 places,at the big bolt where you drain all the oil and at the bolt that is located Above.It is leaking Along the bolt edges.Do you have an idea how can i fix that?
Need a new gaskets if that is definitely where the oil is coming from if all the bolts are at correct torque setting. The drain oil bolt if the one underneath its a copper washer if its the one on the side with the oil filter its an rubber o ring
Don't know if you'll get this comment mate but can you help me with adjusting my clutch cable. Already fully extended the bolt on the clutch lever so I need to loosen that fully and adjust it at the clutch bur no idea
@@No-mn3bw this one is pretty easy tighten the one on the lever all the was in so it’s fully closed then on the engine casing there is a lever the cable attaches too. Lessen the 2 lock nuts so it becomes lose. Then keep tightening the back nut (closest to the front) until the cable is tight up by the lever. Take care not to over do it else clutch will slip you want a little free play in lever. Then tighten the nut closest to the back wheel until snugged up. Hope this helps.
Hey, i changed my water coolant but now when I start the engine, the coolant leaks out of the little hole under the water pump. Do you know why that is?
@@BigBoyzToyz1974 About 20 minute ride its half of the dashboard is this normal? I have a friend with ktm duke 125 and when we ride together and stop and touch engines mine is fire but the ktm is normal. Sorry for the bad english.
@@ГеоргиВасилев-у4о 4 lines is normal mate my engine gets really hot just after 20 mins riding stand bike up straight take dip stick out tighten it back down make sure oil level is correct as these little bikes do burn oil quickly. Top up too the upper level it it will be fine..👍

Hey, i changed my water coolant but now when I start the engine, the coolant leaks out of the little hole under the water pump. Do you know why that is?
your water seal behind the impaler need to be changed in order to prevent water from escapeing out this hole
I've got same rs4 125 but mine is heating up really fast i don't know why?
You say heating up really fast what is really fast and how many bars on the dash?
