Yup... The tw clutch is very much like a light switch, its either on or off. Every Yamaha i have ever owned has been like this ( all dirt bikes).The cable actuated TW200 is not the smoothest. Plus it doesn't have a long engage/disengagement point. It's kind of abrupt.
I have to disagree with you on this statement. One of my TW's has Barnett plates and springs and it performs identically to my other TW which just has a spring upgrade. They are both still light switches with the engagement near the end of the lever throw.Once you have a stiffer spring set installed, the clutch will engage, disengage much more smoothly and over a longer throw of the clutch lever. Stock, the plates release at the very end of the lever's throw, they are that weak.
The original springs are so weak that they nearly need all their resistance to disengage the clutch and engage the motor. In fact, I was able to actually get my clutch to slip with the lever fully out and the springs pressing the plates together, without stalling the bike. Many hill climbs had my rpm's revving up and down as the clutch would slip due to weak springs.I noticed exactly zero length of pull difference in the engagement zone of the clutch after the spring upgrade... don't the springs just apply pressure to the pack via the pressure plate when the clutch is released? Is there an actual change in the distance the pressure plate moves when pulling the clutch lever and releasing?
Im only asking because I'm not a clutch expert and want to make sure I'm understanding things correctly.
Were you only trying it on flat ground or did you try it on some steeper off road stuff? I really noticed it when off road on steep climbs that there was more 'forgiveness' in the lever's range.Of course there is still play, I have a friction zone just as all other TWs with functioning clutches. I was just inquiring about the increase in friction zone during the clutch release... and that I didn't feel any real difference between my stock clutch springs and the Rocky Mtn ATV springs as far as the clutch lever play/action/friction is concerned.
There is still free play in the lever and a "friction zone" but its like an 1/8th of the lever throw max and way out near the end of the throw. Like i said every dirt based Yamaha i have ever owned has been this way and i have owned probably 10 over my lifetime, I have owned YZ's, IT's, TT's etc, none were any different than my TW. There is no adjustment that will widen it or get it closer to the bar that i have found either.If you guys have no clutch play, if it's like a light switch; on or off with nothing in between, then how do you take off from a dead stop? Are you popping a wheelie each time? Stalling? I can slip the hell out of my clutch and I do on many a hill climb. I'm lazy and don't shift as often as I should. I'll short shift, then slip the clutch to gain power through rpm and control speed same way. Especially on uphill switchbacks; I'll give it a good amount of throttle, then short shift and slip the piss out of that clutch to keep me moving forward and upward through the switch. I have a shorty clutch lever and keep two fingers on it constantly when riding off road. On road at lights and in traffic I'll keep a finger on it.
