your tuning is really rich, tune your hp carb, anmd you might want to look into some new gaskets, replacing gaskets is always a good thing

Could be one or more of a lot of things.
Who ported Your Cylinder?
When Did You last replace the Diaphram and other Gaskets in the carb, and when was it last Meterd? It might need a good rebuild and to be remederd.
You exhaust gasket is probably shot, and where the bolts tight?
What are You carb Settings at? Go for a ride around the block, and ride WOT for a while, then Kill it as fast as You can, and What Color is Your Spark Plug?

get it tuned as simple as that, take it to a shop because it really sounds like u dont know what u r doing. then take it home and ride. and dont worry about it im sure its fine. u would be suprised what a wrongly tunes carb would do to u.
