Took a good look, it's all connected but appears a little slack on the return. Not sure what to do about that. Feel out of my depth. So get stuck in and fettle your bike starting with lubricating your cables . How are you ever going to gain any experience ? It's not like you're replacing crankshaft shell bearings, it's just a sticky throttle , how hard can it be ? Has it occurred to you that it might have been like that all along ? I recently installed Slinky Glide throttle cables and now my throttle snaps back instantly. Well guess what? I wish I hadn't bothered! It's a pain in the arse , or rather the arm , to hold the throttle grip in the right position. A bit of friction isn't necessarily a bad thing , after all you don't take your hand off the grip when riding do you ? What you actually do is push the grip forward . So why not just go for a ride and stop worrying. I found the same on long runs at speed so I’ve fitted Scottoiler Crampbusters to both bikes. They work a treat.
