First off...Hi everyone! I'm relatively new to the forum and am already learning so much. I am also very excited about the upcoming 2014 Trikefest!! Can't Wait!! Now with my current issue...I recently jumped onto my '85 Honda ATC 250R only to find the throttle response was groggy. At the top of every new gear it would sputter and if I have it more gas it would then correct itself until I would then climb into the next gear and the same thing would happen until I gave it more gas. It is a thumb throttle, not a twist throttle on there. So....like so many times in the past as I began to search for the remedy my ADD kicked in and next thing I know I'm installing a new handle bar, new grips, bar ends etc. Well as I was taking off the old handle bar and putting the new one on I removed the gas tank and traced the throttle cable back to the lid of my carb. Right where the cable enters the carb lid was a 90 degree metal tub...you know what I'm referring to and it was broken in half..the throttle still responds but that coupler...some come straight up and out..some make a 90 debree and some make a 45 degree. Well...I take that out...remove the slide and start looking at the needle...the needle is a 28V..the ring at the top is half way down those 4 grooves and the needle is all marked up...rub-like marks about half an inch above the bottom tip of the needle. So I ordered the OEM throttle cable...just got it today..when you hook the throttle cable up to the lid of the carb...I threaded the screw device into and through the lid and then secured the small nut onto the screw on the underside of the carb lid after I screwed it all the way in and down...made sure the needle sat down and straight...made sure the large spring inside lined up perfect from top to bottom and then tightened the carb lid. Ran the cable along the main stem of the frame underneath the gas tank and up through the handle bars and over to my thumb throttle on the right side of my handle bars...dusted off my hands..put my plastics back on..hooked the fuel line back up, opened the choke and fired her up!! Let her run with the choke on for about 20 seconds and then closed the choke and took her for some laps back behind my warehouse. Here's my problems now: The throttle has a lot of play now before it tightens when you push on the thumb throttle...I can move it back and forth a lot before I push it forward and it tightens as I excelerate....I can't remember how to fix that...I unthreaded the large screw that screws in directly to the thumb throttle casing and it still doesn't tighten nearly enough; And I still have throttle response problems....meaning...start off in first gear...groggy until I give it a lot of gas...then switch into second gear...groggy until I give it a lot more power..same with third and I didn't go further after that. I'm dumb founded at this moment....I NEED THIS THING TO SING!!!
