*build progress* My RS50 engine swap project

[nidyanazo]

Well after months of doing other stuff (mainly building up my R1) I Got the itch again to do something with my Aprilia, so I'm starting the engine swap process: Currently looking for a donor dirtbike..

Read alot on the forum of what other members have done and got some good ideas...

Looking at a yz125 today..

Will keep you updated

[littlefeller]

does the tzr 125 engine fit?

[nidyanazo]

Not sure, dont have access to any tzr's here. Looked for some time..

The YZ125 is easily available for around $1000...

Going to test one now.. If the bike is solid I'll get it and be able to start fitting the engine this week..

For 1000 dollars you can get pretty far on tuning a AM-6 engine and turn it into a screamer at 14000rpm's, i know what option i pick

I know, I've read many threads about engine swaps and you say that in every one.

The engine in the bike was a Top 75cc big bore kit, Jollymoto full pipe with Carbon endcan, Dellorto 21mm Race carb with foam filter, Ducati ign. box, Carenzini racing crankshaft, Bernett clutch, Pirelli MT75 tires.

and was real fun, but this 2000 YZ125 I just bought freaking rips and shreads way more then the tuned RS ever could. ~33-35HP... Here's the new bike:




It's already got a bunch of good parts on it, and it runs great. $700. Job done.

Got the custom sprocket lined up, and ordering tomorrow. Will be pulling the engine out of the YZ tomorrow also.. Stay tuned..

Plus I like to build stuff.

Check out this 50cc screamer I designed fabbed and welded it all up...

the 125 is the way to go, 40bhp plus is easly attained but does the 50 chasis cope? anyone, would be intresting to know

[RS_Patrick]

Not really wel, but if you dont do anything crazy and remember the bike is extremly light and overpowerd wen you dive into a corner you should be ok, even a tuned AM-6 15HP or more RS50 wil give you a serious problem if you run over a bump or something in a corner.

Hard to tell what type of area these videos are shot in, but if you have any neighbors around you, I bet they just love you rofl.

Dont i know that lmao 30MpH crack/drop in the road and bang bike goes one way then the other then we both end up in a centeral reservation lol

I can't wait to see some pictures. I am starting a build on my friends rs50.
I am putting a YZ85 in his bike. I put a KX85 in mine and it screems. Both of these bikes are track bikes. If you plan to use you bike on the street I suggest getting a lighting coil from HPI igintion to run your lights. Keep us updated on your progress.
