Project, Aprilia RS 125.

[aprilia_simon]

Hi, im new here!.

I have been looking at this forum for a while and have never actually registered before, anyways i bought my first geared motorbike 'Aprilia rs 125' for my first geared bike. It does need some TLC which should be under a ?100 to get it fully road legal but does run fine at the moment. I bought it off a fella in croyden which slipped the bike over as a car pulled in front of him.

Not much damage to the bike!!

In need of:-

- New front wheel + front disc
- Left + right indicator
- Gear Shifter
- Right hand Mirror
- Left hand foot peg

Plans :-

- Respary Panels white, don't know about stickers yet.
- Brand new Giannelli Carbon Full Race System

Cost me ?500.00.

Looks better than the RS125's my mates have (Other than the '08 model)

Liking it yellow and black, but the pillion seat looks out of place, get a yellow seat and tank protector to pull it together a bit better.

Looks pretty good nick.

Little update:

Foot Peg
Gear Shifter
Two sets of brand new indicators

got put on yesterday morning.

I'm sure this is the top head of the engine, it says aprilia on it so its the original one that came with the bike when it was first made?, so it hasn't had a rebuild?. should the new top head say mitika? instead of aprilia when it had a fresh top end?.

That looks like the barrel (cylinder) to me.

Normally when some one says top end refresh to me I assume the engine has got new cylinder head gasket, 'piston bearing', a cylinder rebore and new piston with rings.

should it say it on the red top of the cylinder, the red part is the top head isn't it?, im a bit confussed atm.. the red arrow pointing is the top head cylinder and the one underneath u cant remove.

steveh said to look for a mitika lable on the base of the cylinder is that suppost to be on the red part of the arrow? or at the black arrow?.

That looks like the original cylinder to me. I think you mean 'mitaka'. The piston could be slightly over size than standard, depends if the cylinder has been bored or not.

The gasket would just be a direct replacement

EDIT

Both the cylinder head (red arrow) and the cylinder (black arrow) and be removed form the crank cases. They can be removed from each other aswell. Thus the need for a head gasket and base gasket.

To me the cylinder (black) looks standard, if the head (red) was made by mitaka i would've thought it would be stamped/machined/cast some where on it.

By the sounds of it they have just replaced the gaskets, piston and rings on your bike.

Hope that helps

original barrels can be re-conditioned, so it may well have an oversized piston, then again it could be that the last loving owner has changed the rings and done a "refresh" with the top end.

barrel is original, wether or not its been oversized you cant tell from the outside.

you can take the top off it (red arrow) and see the condition of your barrel/piston, and you can get away with re-using the old head gaskets (two O-rings) but for the sake of a few pence its best to replace them.

If its running fine with no noises etc, just leave it be?

Look down the exhaust port and look for scoring as thats the hottest side of the piston and most likley to show signs of wear and tear.

I wanna replace the piston, but i don't know what piston to get because i don't know if it the original barrier or the mitaka head.

bacily i wanna renew the:-

piston rings
piston
head gasket
bearings

because the head gaskets is gone, i can see browny white oil from the exhaust.
