Freezer said:If you have an old DT50 you can easy fit an DT80 engine. I don't know about the new models.
Futhermore, there aren't that much parts for DT80, you can fit a 110cc Malossi if you want, and get a 24 mikuni with it.
Cruz_e_Silva said:There is also a Polini kit for the DT50/80 LC with yamaha engine.
Usualy here in Portugal the mod is very common and it's needed a 42/43mm aftermerket crank and the carters rebored to fit the 55mm cilinder kit on the 50cc model. The 80cc model is not sold here but only in Spain. In this last one it's a straight forward job. The max speed of those bikes is around 160km/h with tuned cilinders.

markybda said:I do not know if the LC block would fit on a a/c motor because the water runs out of the block into the motor casing (Water pump). I definately know that a a/c block will work on a l/c motor though...
Pro-Tuning said:So it is possible to mount at 100cc (55mm) cilinder on at DT/RD50 motor?
At this point, dont think about how to get at working waterpump
markybda said:are you puting the 55mm on a a/c or l/c motor? and is the block a/c or l/c?

1st:You can't put the LC cilinder in an AC (very old) carter because not only the carter is diferent but the the cilinder studs are in diferent places also. You can convert 50LC to 80LC altought.
2nd: I think the LC carter can be put in the RD50 with minor mods to the frame.
I don't know if there is a 55mm cilinder to the 50ccAC models, only know 45mm from Polini.

The 55mm cilinder im talking about is the 100cc (LC) for DT80
Polini, And Malossi are the brands i have seen
Can you find some pic of the DT50(LC) and the DT80(LC) engins. So i can compare the 2?

Cruz_e_Silva said:Both LC engines are alike from the outside....
markybda said:I have a Dt-50 (LC)... I also have a RD 80 LC... and the rd-80 motor fits perfectly int to dt-50 frame...
I KNOW that you cannot fit the LC motor into the AC frame without modifications...
The 50 and 80 engines are a little dofferent.. like different clutch basket , different stroke (thus the need for a different crank...)
I also know the DT motors have a tighter gearbox then the RD motors... so if you want to go fast, change the box!!!
You are talkink about DTLC with Minarelli engine, not the DT Yamaha engine that looks like the RD one.Pro-Tuning said:I have heard that the DT(LC) engines is the AM6 engins.
Same engine as used on Aprillia RS50
