jape,
Thanks for the complement.

I have three helmets here in Florida and three in North Carolina so I don't have to carry them back and forth on my migration. Oh and two more coming from the Dang Fong vendor as a gift for all the trouble that they have caused me. Of course the helmets are not here yet nor is the paper work or the tools but they are in the mail

Sweet! man that bobber looks so damn good!
I guess I will have to order mine tomorrow =)

Few things you might want to do cosmetically and cheaply, drag bars and also remove that plastic can for the electrics swap it out with this one http://www.tcbroschoppers.com/store/...roducts_id=128 they also sell the drag bars very cheap. Actually I'm sure you can find anything you need from that site including a more comfortable seat.
As for making the bike run cooler and getting maybe .02hp back remove that EGR, it should keep the motor about 10F cooler without it. I can foresee in the future rejetting and opening up the exhaust slightly with either a straight pipe or a little bit longer angled up.
I feel bad for my girlfriend so I'll wind up making a clip-on passenger seat in the coming months as well. I would love to see if the kikker5150 springer front end would fit as well =) Like I said the things you can do to this bike are limitless. I know barnone would like to see that 400cc in here and I don't blame him at all the 200cc barely cuts it. I'm sure if this is the honda clone we might be able to find a big bore kit and bump it up to 300cc but I don't know how reliable it would be... Once I get my paws on one of these I'm sure I can figure it all out =) Actually just found the big bore kits: http://www.chinese-parts-canada.com/...bore_kits.html

Aboshi,
First thing I did was remove the SAI (Secondary Air Injection) and cover the hole with a aluminum plate and plug the hose on the intake manifold with a bolt.

Good find on the bore upgrade kit. I tried to send that company a message asking them to pursue the 400cc engine but was unable to get past their anti spam blocker.

I did get a conversation going with Mr. Bryon Zhou and he said that his company did not produce that engine. I asked him who did produce that engine but got no reponse. Might be vapor ware as some have suggested.

Like your idea of replacing the plastic oil tank with a metal one. Good to have others getting this bike and coming up with more ideas.

Need a little breather to eliminate that hose that goes to the oil tank.

Gardo,
Great photos.

My pallet was also badly damaged but not as bad as yours.
Bike is looking good.

After looking at those pics again, it looks like you can take that breather tube from the case and attach it to where you installed the block of plate for the EGR.
This is called a pair sucker mod, its usually used on 2002 + GSXR 750's and other race bikes and typically costs around $2k+, but it was as easy as just attaching a hose for $1 and gaining 12hp. What it does is creates negative pressure inside the case removing all the air so the oil can flow without friction. I would have to do a test on this motor to see if the pair sucker mod would work but if it does it would 100% add at least 1hp and make the engine run a lot better.

Good news for me. Received the correct MSO and bill of sale today and rushed over to the Tax Collector's Office and got her registered and tagged. Only took a month from when I ordered her to get the correct paperwork.

The promised tools and helmets have not arrived.

I'm now legal with the bike.
