For street riding on concrete or asphalt a standard chain is good but if you ride on dirt or gravel roads an O-ring or X ring chain would be better.

Any recommendations for a replacement? Should I put an O- ring or X-ring chain on or stick with the standard roller chain?

Do you guys notice noises in the rpm range mentioned above? It's been a bit noisy from day 1 and runs great so I assume it's normal.

I did my 1st top speed run today and hit 74 on the speedo. Not sure how you guys are hitting 80+ . I'm 185 pounds and was tucked behind the windscreen.

Like Jerry said a standard chain is fine and is what I run as long as it’s good quality but you need to clean and oil it more often. If you don’t like doing the maintenance then o or x ring chain would be better. As far as top speed several factors go into that on a small displacement/hp motorcycle. Has the chain been lubed, axles greased, bike roll easily, tires properly inflated. But the biggest thing in this bike is obstructed exhaust flow. I opened mine up so it’s less restrictive, at the upper range with stock exhaust the power falls off. If you uncork the exhaust the engine will rev better especially in the upper range

Thanks guys! I like doing my own maintenance and will stay with the standard chain. I cleaned and lubed it when I installed the 16 tooth sprocket.

I really don't need it to go faster as I bought it for fuel mileage and just filled up yesterday and got 102mpg so really no need to mess with it. I think 74 is probably normal for the stock bike.

Not sure if I want to drill out the stock exhaust. I've seen the KPMOTO exhaust and read that it helps the top end but I really like the look of the stock exhaust.

If I want to go faster, I'll just have to go on a diet....or paint it red like herbie's!

Red is the fastest color

Has anyone seen a better photo of how the USB Port is mounted on KPR's that come with one?

I guess this is a China option we don't have?

edit: Found it!

Found the factory stainless steel exhaust much cheaper here. I wonder how much it costs to ship something like this. Anyone know the weight of this?

That's awesome! Hopefully, they come with the O2 sensor bung instead of how it's pictured.

Decided to try one of the KPT200 exhausts from eBay. It is $160 shipped and the muffler comes in a variety of sizes and colors. I opted for a black muffler and hope it works well.

Let us know Jim how it works out, that would be a relatively inexpensive option for an exhaust upgrade. Hopefully it will come with the O2 bung on it and mounts right up for you.

Will do herbie. I verified with the seller that it does have the O2 bung.

Fantastic!

The exhaust arrived this morning. Unfortunately mother nature is dumping rain for the next few days so I won't be installing it until next week.

The piping is all stainless steel and has the provision for the O2 sensor. The muffler has a removable baffle in the rear. The welds look awesome and the quality seems great!

[herbie]

Dang it Jim, now I’m going to have to spend more money!

[JimS]

Glad I could help you lighten your wallet herbie! If my wife notices, I'll tell her that it increases the fuel mileage.
