What is the top speed on your China Bike?

[ChopperCharles]

So, over time, it's been harder and harder for me to reach the same top speeds I once easily reached with my Buccaneer. I still can get the higher speeds tucked in behind traffic, but free and clear in the open air, not so much.

Well, a couple days ago I noticed my revs climb just a bit when I chopped the throttle and then immediately gunned it in 5th gear at 70+mph. And after that, I experimented a bit more, and I definitely have clutch slip. It's not noticable in the lower gears, but in 5th on the highway at > 70mph with all that headwind, I can make it slip pretty easily now. It doesn't slip a lot, but enough.

What's the general life of a Chinese clutch on a 250cc bike with a fatass rider? I've got just under 7000 miles on it so far.

Fortunately my motor is an XV250 Virago copy, so I've ordered a Barnett clutch and springs that should drop right in.

Has anyone else had to replace a clutch with relatively low miles?

I guess in bigger bikes I've also worn out my share of clutches. OEM clutch in my V65 Magna lasted to about 16k miles. Barnett clutch lasted another 74k after that, before it too was worn out. CX500 clutches worn out in about 20k miles. But this is the first 7000 mile clutch

I'd just a little under 7000 miles if you're experiencing the slip.

Got a 2020 Boom Vader this past March and am still in the process of break in. I have had it up to 47 mph a few times on my way to and from work. Straight and level road for about 1 1/2 miles each way. I calibrated the speed-o and it is accurate up to the 47 mph I have had it at. checked it against a know accurate gps as well as a police radar gun (my neighbor is a police officer). Only mods at this time are the 17tooth front sprocket, replaced the stock chain with a HD DID 428 chain and added an oil cooler for the motor. At present the bike has 119 miles on it and like I said only gone up that high a few times. Am 6'2" and 255 lbs to boot. I did still have a bit over a 1/4 throttle left on the bike at that speed. I do have a new PZ22 carb for it as well as an assortment of metering jets when it comes time. Any idea on what jet to at least start with when I do decide to swap out the stock carb? The shifting is still a bit clunky (sounding ) and getting into neutral is getting easier as well (especially going to neutral from 2nd gear). I love the little beasty and use it mainly for going to and from work. (only about 5 1/2 miles). Would I buy one again? Yes as well as a 250 multi purpose bike.
