without hearing it for myself of course, I would say you are describing normal shifting. Don't forget, your sitting on the mechanical parts with minimal vibrations, sounds and clunks coming thru loud and clear. With so few miles, I would doubt it has issues.
when shifting, your goal is to be smooth. Matching the motor speed with the rear wheel as you let out the clutch takes practice. From what I understand about the mechanics of the clutch, you can hold the clutch in all day long with no ill-effects. Some time back, there was a thread about this.
I have seen the roads on the big island and I am jealous. While I was there on Uncle Sam's dime (25th Infantry Div), I wished I could have ridden up to the higher elevations. As it was, I had a 80lb pack on my back, and anything with wheels and a motor would have been sufficient.
ride safe, TIM

 

Clunks are normal shifts. When you hear the double clunk, you know you are in first gear. After awhile you will feel that double clunk and feel confident of where you are. Sure a bit of throttle as you are shifting up through the gears is expected. If you are abruptly slowing it down when you shift you were wrapped out too high and didn't get on the throttle enough when you got tot he higher gear. If it pings and wants to folter, you probably shifted too early and are in the low end of things. Just get on it and ride and you will eventually feel where it wants to be and what is safe for you. Now downshifting is more precarious. Be especially careful not to downshift to quickly, i.e. to arrive at a low gear when you are still going much faster than appropriate. That will send you into a rear wheel slide, not good foranyone. Ride safely in your neighborhood, make many turns, accelerate, slow, and do it all again. Then you will fee confident of where you are and where you are going. Tom

 

The lurch-ey part sounds like your chain is a little loose, or in need of service. Download the owner's manual from the technical writeup part of the technical help forum and make sure your chain is in adjustment, cleaned, and lubed. However, it's better for the chain to be a little loose than too tight.

I'm not sure this is what you're asking, but I know I read somewhere it's not recommended to coast very far with the engine off. It's probably in the owner's manual, too.

I think the TW would be a lot of fun on the Big Island!

 

Adjusting the chain tension is a simple and easy job. It will take you less than an hour - probably less than 20 minutes to be honest. Just make sure the chain is in spec and then lube it up. It's a wet clutch, so I guess I'd also say take a look in the little window on the lower right side of the block and make sure you've got oil in her! Check your clutch return spring too just in case.

 

Kundu,

Congratulations on your new purchase. You have the best year. After all, it is the bike in the graphic at the top of the forum header.

All of my TWs "clunk" to some degree when shifting.

Enjoy your new ride. Hopefully you have protective equipment to wear.

 

Aloha:
Anyway, my question is that the shifting sometimes sounds a bit loud or "clunk-ey" while both up- and down-shifting. Also (and I've only ever owned one other bike as comparison), when rolling and coasting in any gear (but especially second or third) with no throttle, the bike seems a little "lurch-ey" or at least not smooth and effortless (like it would feel if you were rolling in neutral).

This is normal. At this mileage you should change to a full synthetic like Mobil 4T Racing oil. Your clutch will free up significantly. It won't change the "clunks" much though.

Shifting smoothly just comes with practice; adding or reducing throttle to smooth out the shift will become natural. I blip the throttle when downshifting and add just a tiny bit when upshifting, unless I'm accelerating at max, when I just snap out the clutch and grab full throttle simultaneously.

I sure hope the original owner didn't change the "injectors" on a carbureted bike!!

Don't ask me how I know after 45 years of riding!!!!

 

Welcome aboard the coolest site on the net.............. It's a matter of "practice/practice/ practice.....Your bike will loosen up with miles.... Next oil change do the syn. oil. You will soon be shifting like a pro........ I find myself shifting different on my off kilter days. But most days my bike shifts quite smoothly...Have fun learning. AND WATCH OUT FOR THE OTHER GUY.... OMM.
