Okay here is what I have here a 2008 TW200 with 4,000 miles on it. Had to replace the float due to someone's stupid fix on the carb. So no issues there. What is happening is, in 2nd and 3rd gears when you grab a hand full of throttle, very lack luster response. Engine rpms come up though not much any mph response. Kind of tells me of a clutch issue. Higher gears it is a bit better though still acts like it is slipping some yet. I want to pull the clutch pack and check the friction plates to see if they are glazed over. Maybe add a couple stouter clutch springs to improve the pressure on the plates. Not sure if an energy gag conserving oil was used in the engine. One other thing, the chain. parts fiche says 428HG 122link chain, I want to put a better chain on possibly a oring chain. Any suggestions on that?

Lots of threads on the chain if you search.The O ring is the way I would go but there are a few options you may like better.As for the slipping, start with the oil and check the adjustment and also the return spring placement.Some of the guys had issues with the spring being in the wrong position.

I'm from New Mexico. Clutch adjustment is fine and return spring is as well, as far as the oil, if the wrong type of oil was used, would still have to pull the clutch pack out and give it a good cleaning to get any residue off.

The clutch will usually slip in higher gears earliest when it's wearing out. There are many threads about the weak clutch feeling. But it works.
These bikes are not powerful but the engine should rev to 9k and move it through the gears as it speeds up. Just not that quickly.

Hummm . . . Sounds like bad clutch disks due to wear or wrong oil. The Forum goes around and around about oil but, basicly, any good motorcycle oil make for wet clucthes should be fine.

If it were me, before I tore it down I would drain the existing oil, invest a quart of your moto oil of choice, and see if it gets better. If not, tear it down. If it does help, drain and replace the oil again. That might do it.

I am not sure how many miles most TW owners get on a stock clutch but mine (1995 w/3,500 mi) is so grabby that I can not imagine it being worn due to slipping. If the disks are bad you might try the Barnett Kevlar disks some guys here are using.

Or get an X-ring chain. "Shopeddies" seems to have the best prices but you will have to remove some links depending on which chain you get.

Get an extra long chain and remove what you don't need but save it. In the future if you decide to use a larger sprocket you will have extra links you can add onto the existing chain.
