He's talking about when you install the bbk. If your keeping the stock carb, you'll need to buy a couple of jets for the tk carb.

I run 130/90/10's front and back and I may have lost a mph not really sure though. I don't really notice the speed decrease but the handling and ride definitely outweighs the loss a tiny bit of speed.

Good to know on the front tire, thank you. I planned on changing the carb when i get the bbk. Until i get everything delivered to me i will keep it stock. Right now im just stocking up parts

That's the way to do it. Just ride stock until you're ready and read as much as you can while you stockpile parts. If you run into any issues and need parts for your trophy, let me know I've spare parts I never used when I ran the trophy.

got the exhaust and rear brake shoes today. The exhaust seems to have 4-5 "dents" in random spots. I think i remember heard this was normal. I had ordered the "ZX" but they shipped the "zxr". I wanted the zx because of the shorter muffler. As far as i read here I should be able to put the pipe rollers and springs on without jetting since its still 50cc and stock otherwise correct.

The dents are supposed to be there. I didn’t have to do any rejetting when I ran the ZX on my stock motor. Just take your time with the install and make sure there aren’t any leaks. I like to thread the two bracket bolts in the case just enough to hold it and then tighten down your flange studs/bolts. After you've torque your flange bolts, tighten down the brackets and get tuning!

the 130 front tire will really kill your top speed on a 50 but with the bbk its not as noticeable. it feels better on pot holes, it levels out the seat, and it gives you more rake in the front end stabilizing the scooter a bit at faster speeds.

I got it cleaned up a bit more. When I took the reed cage the gasket ripped. Since the cage is hard plastic I assume I need to put another one? I asked at the local Yamaha dealer and they said they don't just sell the gasket alone. Thoughts?

I usually pick s few up with my orders from larger vendors scooter attack etc. Most aftermarket vendors sell them for a couple bucks each. You could make one out of gasket paper thats close to the same thickness. Just be sure to put a thin film of Yamabond or similar to be sure you don't have leaks. If I don't use a skim coat I always come up with leaks at the reedBlock.

You could also make that gasket out of gasket paper or whatever it's called (not that I've ever done that). And while you're at it - if you're going to put in a big bore, anyway - replace the reeds with carbon fiber ones.

In general you want to be careful when removing parts that have gaskets, because they're fragile. That includes the gear cover, crankcase cover, and other things.

The typical reason is that the oil sensor gets forced out when you overfill it just a little. I need to wedge mine back in properly too. :)

I ordered the gasket along with some carbon fiber reeds so im waiting on those to come in. In the meantime i posted something in the parts review area and have never got an answer. Can someone help me out here.


I searched and could not really find a comparison of variators. I see them from $62 for athena to $99 for polini to $134 dr pulley. Can someone shed a little light on what makes one better or different than another



$62 http://www.motorcycle-superstore.com/5/ ... toComplete


$99 http://www.drowsports.com/product/143/T ... Horizontal


$134 http://enviromoto.ecrater.com/p/1418339 ... tor-yamaha

When people say to mix the variator a weight is this what they mean? Also I pulled the plug which I think is the wrong one. It at least doesn't look lean.

Last night I ran into a little snag. The new exhaust flange doesn't not sit flat like the stock one. Any thoughts?
