Hello, We are changing a crankshaft for derbi d50b0 engine( senda xtreme) And one gear wheel doesn’t come out, the first one on the bottom next to the clutch. Should we take off the clutch to take it out , because we think it’s not necessary to take if the clutch ?
Hello , i have aprilia sx 50 with the same engine and i want to put 80cc top performance on it ( 78cc top performance) . Do I have to grind the crankcases to fit this cylinder and crankshaft?
Hey guys, sweet vid! I’m wondering if this 80cc kit would work on my Polini XP65R engine. They use an EBS050 engine with a 65cc jug and piston. I’m wondering if it’s as simple as swapping on the larger piston and jug on the stock rod/crankshaft? Thanks very much!
good job but next time hit only the outside of the bearing and heat the cases more! also dont hit the crank like that just heat up the bearing. also you forgot the locking washer on the clutch hub, just for next time you biuld an engine reminders
Top build. Maar ik zou je wel aanraden om beter een dop van je doppensleutel set te gebruiken om de lagers er in te slagen. De oude lagers zelf werken ook vrij goed maar er is meer kans dat je de binnenkant van je nieuwe lager raakt en dat kan problemen geven
it probely didn't, but you are right the proper tool is a crank puller. luckely i invested in those tools some time ago but this video is a littlebit older. those 2 light taps won't effect the crank critical and im sure there it will be fine for this mildly tuned setup
@@restorationandbuilds5899 a rubber mallet is not going to bend the crankshaft, a good old metal headed hammer will, i have hammered my crank, transmission, bearing everything pretty hard with a rubber mallet and everything is completely straight.
what is that carb?? I am looking to buy a bigger carburator and i just do not know which one Do i pick? I have a Derbi senda xtreme 80cc airsal Can you help me please? Because there are so many options. Do you know who fits the best for my bike?
The clutch oil is the same as the gear oil, the tank is shared. So just use the oil you re going to put in. Regarding Nm for the engine block bolts I have no idea but be very careful as I remember the thread on the block wears easily…
I have my derbi senda 50 2017. Water pump leaked and lost all the coolant. It of course heat seized once and locked up. I got some water and fired her up, that was enough to get me to my destination. Problem is i have exhaust fumes coming out of my coolant tank.. so im thinking the head gaskets blown. Ive never done any major work on bike engines but i know how they work. Im an engineer. Now, i suppose i should take the engine out, take the head off and have a good look around, see if anythings warped from the heat. So on. Change the gasket. Replace the water pump and chuck it back together with common sense and knowledge. Would that be far enough to get her running proper. Also can the maintenance manuals be found online if i get stuck? Is this something i should be able to do relatively easily Any specialist tools required. Bike is all standard
Transfer ports matching? Measuring and adjusting squish clearance? This engine maybe looks good, but it will never run at 100% of potential this cylinder kit has.
thats not how you mount bearings, heat the casing up enouch next time, they schould slide in or go in with light-medium pressure. and if you need to tab them in only hit the outer ring
The AM6 must be the best 2-stroke 50cc engine ever to be put into a motorcycle, I have one to put into my 1979 FS1E, after it gets a rebuild that is. That base gasket looked a bit out on size compared to the ports, or was it the camera angle. What about the oil pump, they are no use with a big bore are they? pre mix oil.
@@Masairasink No it's not, it's a D50b0 or Derbi euro 3. Rabasa, or Derbi euro2, is either with or without counter rotating shaft, but it takes a lot of space right under the intake side. In the casings of this video you can clearly see that there's only space for a small cylindrical shaft. Rabasa's have a casings that looks much alike AM6 seen from the inside
Je kunt ze op hbm machines halen, er is nu flinke korting. Het is prima gereedschap maar niet van proffesionele kwaliteit maar daar is de prijs ook naar, op internet zijn er genoeg te vinden.
Where's your clutch lock washer? Crazy that should always have that or replace it asap if you don't that coming off would give you as much as a smile as your piston going through your tank

my original crankshaft have 1000 km , can suport this cilinder ?? why this cilinder cost a lot of money ?? thanks from spain
i recommend stronger one, but works with original too. malossi is quality brand so thats why its expensive.
The origina crank is the best one for these so i wouldnt change it
Get a stronger one
6:35 Waar heb je die 2 zwarte dingen gehaald die de koelgangetjes dichten op de zijkant van de kop?

I'm struggling to find torque specs for this engine how did you find them ?
Theyre not that important. Go by feel. Been building engines for ages.
naaah, you can find them in the service manual
You don't need them just go by feel everyone does that

Tätä oli kiva kattoa ;)
did you have to run a higher spec transmission for the power or did you use the stock setup? Thanks
stock setup should handle it as long as you drive properly, but its not a bad thing to upgrade the transmission anyways

Does the carburetor have to be leveled properly or can it be tilted? Does it make a difference? (Dell`orto 21 Red)
It doesnt make a difference but when it starts leaking out the float bowl you need to level it a little bit more
what was that blue stuff you put on the screw?

how much is fuel consumption at this 80ccm cylinder ?
Every bike is different, but it should be around 1:10-1:15 (litre:kilometer), also depends on how much throttle you give

Its to make the metal in the engine case expand, so the bearing fits
