malcolm Posted May 30, 2015 Report Share Posted May 30, 2015 I have a gas gas 125 txt 2012 and I want to make the throttle easier to rev , or in other words make it softer. It is currently far too hard for me. Could anybody give me any advice ? Thanks Quote Link to comment Share on other sites More sharing options...
jordi Posted May 30, 2015 Report Share Posted May 30, 2015 By too hard, do you mean the throttle is stiff? Try removing the throttle body, clean and lightly oil the handlebar end, take apart the throttle and make sure its clean. Quote Link to comment Share on other sites More sharing options...
malcolm Posted May 30, 2015 Author Report Share Posted May 30, 2015 Yeah i think it might be that the spring is just too stiff for me , thanks for your reply Quote Link to comment Share on other sites More sharing options...
mazz46 Posted May 30, 2015 Report Share Posted May 30, 2015 If everything's o.k with your throttle cable and tube cleaned and lubricated correctly? . you need to get to the gym because them throttle are light 1 Quote Link to comment Share on other sites More sharing options...
lineaway Posted May 31, 2015 Report Share Posted May 31, 2015 You can clip a little off the spring. Not too much. If it is harder than it used to be, it`s possible that the bar has become grooved under the throttle. Quote Link to comment Share on other sites More sharing options...

baldilocks Posted May 31, 2015 Report Share Posted May 31, 2015 Malcolm disconnect the cable from both ends. Slide the rubber boot from the twist grip end along to the end of the cable and hold vertically so it acts like a funnel. Fill with wd40 and work cable back and forth until wd40 runs out of the other end. This will make a noticeable difference to throttle action Quote Link to comment Share on other sites More sharing options...
nigel dabster Posted May 31, 2015 Report Share Posted May 31, 2015 usual things first as above, but is it "whipping" back when released? Quote Link to comment Share on other sites More sharing options...
dan williams Posted May 31, 2015 Report Share Posted May 31, 2015 The spring keeps the slide from bouncing around and causing self actuation. I'd be real hesitant to mess with it. Of course someone could have fitted a heavier spring. Try another with the same model carb to see if it feels the same. As above make sure the bar is clean under the throttle tube, lube or replace cable an make sure the routing isn't pinching it anywhere. Note that most modern cables have a Teflon inner sheath and don't require lube so if you see a significant difference with lube it's probably time for a new cable. Make sure the slide is operating properly. It should snap back with a THWOCK sound when you let go of the throttle. A clean carb is a happy carb. Make sure the throttle is not mounted on the bar in such a way that the end of the grip is binding on the end of the bar. Lube the pully wheel in the twist grip. There could also be assembly issues with the carb. If someone didn't assemble it properly something could be binding. It is a simple system but also delicate.

lineaway Posted May 31, 2015 Report Share Posted May 31, 2015 Just a side note my son`s Raga with the spring cut just so, is surprisingly perfect. Best throttle I ever felt. Almost too easy, but feels great. P.S. previous owner cut it. Quote Link to comment Share on other sites More sharing options...
perce Posted May 31, 2015 Report Share Posted May 31, 2015 i thought everybody cut the spring? Makes for a much easier throttle. Quote Link to comment Share on other sites More sharing options...
dan williams Posted May 31, 2015 Report Share Posted May 31, 2015 Hmmm I could be wrong. Then again a lot of these carb designs really started out as street bike or scooter carbs so.... Quote Link to comment Share on other sites More sharing options...
guys Posted June 1, 2015 Report Share Posted June 1, 2015 Could be me but I've never felt the need to cut the spring. Just keep everything in perfect working order and don't hesitate to fit a new throttle cable. Quote Link to comment Share on other sites More sharing options...

Well I suppose if you're just flag dancing a throttle spring that's too strong & gives you wrist ache is going to be hardly noticeable.

guys Posted June 1, 2015 Report Share Posted June 1, 2015 Sorry, I've never danced properly in my life, and certainly not with a flag in my hands :-), but been riding motorcycles all my life and never had wrist ache. Like I said, could be me. Quote Link to comment Share on other sites More sharing options...
