ticket2ride Posted September 13, 2009 Report Share Posted September 13, 2009 Chaps, Been playing around with this 125 for a couple of weeks now and at my wits end!! Looking for some advice on carb set-up.... It's a Keihin - 52 pilot, 127 main, needle on middle position.... I've been told that this is the standard setting for an Evo.......but, I just don't seem to be able to get the thing to pull off the bottom in 2nd without it choking up/stalling.... Starting to wonder whether 2nd is only good for full throttle sections/climbs etc... Anybody out there have any thoughts on jetting/needle alternatives?? Or how to ride a 125!!! Cheers!

spudsdad Posted September 13, 2009 Report Share Posted September 13, 2009 hi scott, my son rides a 125 evo, and to be honest it runs spot on on the standard jetting with castrol tts oil mixed at 70:1. he probably rides 90% of sections in 1st gear only using 2 and third on bigger climbs and mud. i take it that you are an adult rather than a schoolboy rider? if i ever ride my sons bike i find that it seems to bog in 2nd gear ,then again i am about 5 stone heavier than him. perhaps you just need to rev it harder as its only a 125 and they dont exactly have that much flywheel weight for being grunted through sections in 2nd gear.

yamahaty250xox Posted September 13, 2009 Report Share Posted September 13, 2009 Differnt bike i know, but my rev3 125 (07) will pull 2nd 3rd off the bottom no problem. Just like my old montesa 315! I have a 105 main and a 45 pilot. Quote Link to comment Share on other sites More sharing options...
ticket2ride Posted September 13, 2009 Author Report Share Posted September 13, 2009 ...thanks for the comments guys... Spudsdad - any idea on what jetting/needle position you have on your set-up? Did you have any joy with those V-force reeds btw? yamahaty250xox - I'm guessing that you're running a mikuni? I am wondering about dropping the pilot jet a tad.....see if I can lean it out a bit off the bottom. When you give it a handful in 1, 2 or 3rd it pulls really well.....find it's only on 1/8 - 1/2 throttle that it struggles.... Cheers chaps...
