hello! Here are some renovation photos of my Honda cr 125 SRS. when i bought this motorcycle i didn´t had any idea whar srs stod for.
SRS oh well, I thought, they were probably just a few engine covers so they would look cooler. but they turned out not so, when I received the review of the guy i bought it from told me that a switch to the ECU box "cdi". and some other stuff that was replaced on it.
Honda has never had a reputation to produce good 125cc but I didn´t knew that. but have race the yamaha 125 "yz" and with good results so I am very pleased with this purchase.
things that are redesigned to it as far as i know anyway is.
the head is changed to SRS
connecting rod is remade by SRS do not know what they've done, however.
cylinder is ported by SRS
it is a DEP pipe on it
the carb is bored a bitt by SRS
FMF reeds they should be installed now.
and certainly other things that are made.

I got my eyes on a small odd spot on the swingarm

I thought it sounded strange in the fork legs so I open them and checked for broken components, but found nothing.

and when I caught sight of the purple bushes that apparently will be better than the original

and that was also some dents in the exhaust pipe so I cut out that bit and hit the dents back and weld it back

and the gray-haired old man helped me to gas weld it so they will hold together

this is how it looked after an hour of screwing.

I hear always disturbed me on Honda's framework, they are very dull!? aluminum's invented to be polished. so I did just that!
(http://img687.imageshack.us/img687/4636/dsc04624n.jpg)
and this is how each of the following 10 timmart grinding and polishing with Autosol.

This is also a bonus picture of FMF reedsen and the original. compares the port area
(http://img530.imageshack.us/img530/8746/dsc04639g.jpg)
also saw that the rear shoc had to start leaking oil. so it must be renovated.
(http://img844.imageshack.us/img844/3662/dsc04431k.jpg)
3/12-10 it hawent hapend much but I've left the cylinder head to the local motor grinder. Apparently, I have run so hard that the aluminum between the O-ring and the cooling channels melted away. so they will they have to fix for me.
then I got home my FMF ram valves and I'm not completely satisfied with FMF's design on them. for the first so I had to grind away lot in the intake manifold. and for the other so where I had to cut away a piece of the. but but if you have a 40mm carb and the original reedsen has a port Aeria suited for a 34mm they may have been worth it.

and has also picked apart link stocks to swing and shock .... I let the picture speak for them.
(http://img10.imageshack.us/img10/7258/dsc04647j.jpg)
and drained the engine oil .... has run with it for about 10 hours, and yes the picture says realu mutch. would think that oil takes the color of aluminum clutch plates ... will probably change the whole package and then they are hardened steel and harder clutch springs as well. it was all for now!

5/12-10 update. have to start picking up the parts that whas finisd. that is not so much but they're always something.

has made a Boysen power wing may not be as visually attractive but serves the purpose I hope.

Looking good! I love rebuild projects. ;D

Yeah I love seeing rebuilds, cant wait to see the end product!

the pipe looks in a fraknstein way :))
love the cut side number

I'd get a new exhaust pipe. When the expansion chamber gets this beat up it does strange things to the power.
What is that "Falcon" sticker on the rear shock reservoir?
-
That looks great! You plan to hang on to it?
