Whatever you do don't blog it on BCF, people have serious anger issues with Chinese bikes!

My colortune and 105 jets came but I've now got an issue.

Using colortune I have a nice blue flame on idle and when holding an RPM, on acceleration flame color is yellow (indicating rich), this all seems fine, but when I take it out on the road, at below 4k revs it handles fine, but mid and high end it pulls really slow and stutters like a flat spot, can't understand why

Maybe not enough air? Make a way of getting more air in the airbox, drill, feed etc
Also freeing up exhaust flow may help

Be careful going for a wider tyre choice. The rims may not be able to take it comfortably (they'll fit but if the rim is narrow, it'll pinch the tyre therefore changing the profile/shape which may actually have the reverse effect in that you can't use all of the tyre properly). Get the best tyres you can in standard sizes, you'll not go wrong with Bridgestone/Pirelli etc. Don't be tempted by the sticky stuff either, get something everyday with tread - I doubt you're going to be getting sticky tyres hot enough to work properly when you're commuting. Stick with it though, it's great fun. I started on a 100cc and worked my way up to 1000cc v twin superbike. Love it (except when it rains and I've got semi slicks on!)

Forgot to mention, airbox is gone with a new performance filter and new sports exhaust are on :S

Sorted my problems, revs like the YBR now and shifts so much better midrange

I mean how did you solve the top end running issue.

sh!t bolts and tapped studs, so I was getting an air leak on the carb, basically when hand tight the nuts were coming loose, so i replaced them with nyloc nuts, then the studs were done up awfully, so i used some loctite one one side and the nyloc nuts on the other.
