@ Sir Traxx

Sir, i want ask to you. Before, i so sorry if OOT.
In my country there are regulations prohibiting the use of racing exhaust. in some areas even using rules 'off racing muffler in place' to replace the factory standard exhaust. Does this also happen in your country? if you do not mind, please tell us briefly about the rules of racing exhausts use in phillipines.........

BTW, do you set ignition timing on CDI Rextor higher do you have? or did you use the factory settings......

You'll have to tell me how many degrees you rotated the new TDC mark on the sniper rotor, from the old one, I estimate about 41 degrees clockwise. Most Yamaha keyways positions are in the 12 o'clock position on their cranks so that's somewhere around 105 degrees if you use the keyway as zero, am I close? and did you mount the trigger in/on the standard mount post position or move it in towards the sniper rotor, as there's almost a 4mm gap between rotor and trigger/sender. Cheers jeff

our laws here in our country are vagued (not very clear). The law said you cannot use any vehicles that emits irritating sound
but theres no specific decibel. so we can use any exhaust pipe as long as theres a muffler on it.

i use rextor cdi with retard 1 to 2 degrees

i dont know the exact degree because i dont have degree wheel.
what i did is i measure the original position of the sensor relative to the magneto pulser from the original sniper engine.
then i use that to the r125 engine with the same specific distance (pulser to sensor) from the sniper engine.

That's cool traxx, understand completely and not so bad an idea as CDI can take up fine tuning.

My bike, YZF R125 when it was a road bike had standard gearing of 48 rear /14 front. And a top speed of 134kph. swapped the front to a 15 front and managed 139 kph down hill, lost a fair bit of acceleration in 4th and 5th gear and most of the time could only just pull top gear to 130 kph, stock motor had no power really. Swapped back to the 14.

R125 rear wheel is 130/70/17 tire, somewhat over tired for a 125...... grand prix 125 and moto3 use 120 or 110 rear and get plenty of power down, like 3 times as much as R125:(

long time no see ate V.. just wondering.. is it safe to use nitrogen air in our bikes' tires for daily use? Is it even better than the usual air we pump into our tires?
yes its safe
In addition to the reply of sir traxx, yes it is very safe.. Why? kasi kapag ito ang kinarga mo, your tire pressure will be constant regardless of ambient or road temperature.. mag-iiba lang yan if may butas gulong mo.. hehehe the advantage also is that yung tire life span mo is mas tatagal compared using compressed air.. compressed air is subject to change in pressure with respect to temperature kapag nainitan or mainit.. kaya tumatagal yung buhay ng gulong mo (di agad mabilis mapudpod) dahil constant ang tire pressure mo at di siya ganun nag-iinit..

Ang daming nitrogen sa planta namin (Liquid or gas), hehehe kaso di ko pa nalalagyan bike ko kasi layo ng planta namin..:(
