My restored Yamaha RD125LC MK2

[rd125lc85]

In june i took my LC off the road with the intention of stripping and rebuilding it. The reason why i took it of the road was mainly down to the crank main bearing being destroyed due to the lightened flywheel breaking up. However it was also showing plenty of wear and tear around the paintwork.
I stripped everything, having many things powdercoated and polished. Me and a mate both took our paintwork down to Martin at Toxic Crow, with pleasing results.

After having rebuilt it, the bike has many tuning parts i have fitted, these include:

1. V- Force reed block (very recently fitted, put in while rebuilding engine)
2. Lightened flywheel
3. 2 reed spacer's
4. K&N style filter
5. Micron power pipe
6. Re- jetted to 240
7. Slight tickle to ports

Having ridden the bike tonight for the first time since fitting V-Force reed block and micron (previously allspeed) the bike is suffering more lag before the powerband, but when in powerband it goes like s**t of a shovel, where as the bike used to rev more freely before the band. Has anyone got any tip's or ideas for setting up the carb after these mods?

Hope you enjoy looking at my pics.

Those V-Force reed blocks are really good for racing , thats one of the first mods motorcrossers do , but are they really suitable for everyday use ?.............probably not mate , try your bike with the standard block and see if it makes a difference

You'll probably need to go down one jet size too.......worth a try if nowt else

Bike looks great by the way

Thats a bitchin looking bike mate .
Practicaly every LC and ypvs speshel theys days runs V force reeds and everyone says they give a big improvement so i think they will give a good bit extra to your 125.

Bloody clean bike as well. and the paint look mint.

Did the bike run the standard airbox/filter before?

your bike looks stunning mate,what have you used to spray the gloss black part of the micron?
it looks powder coated,i was thinking of getting mine powdered but im a bit concerned about it withstanding the heat,i just did mine in pj1 satin black heat proof but it isnt perfect

[rd125lc85]

i used pj1 gloss black
