time for intake/exhaust upgrades

I am looking to spend between 250-300 dollars on upgrading my intake/exhaust/head.

I have a basic run-of-the-mill 66cc engine currently w/ a slant head. i have only upgraded the ignition to a better CDI with a 3 "pronged" spark plug as well as a 39t sprocket.

I have read great things about the SBP xchamber exhaust. My only gripe is the $48 shipping charge, if they sold carbs, heads and other goodies it would be fine. However im yet to find one that compares to it. this would be the closest

looks identicle to this one

I may have to spoil myself and buy the SBP one.

The verdict is still out on which carb to get. im leaning towards this dellorto type one. which i can get for $40 w/ free shipping. I can get a head from this same place for $25, they say its re surfaced and has different compression ratios to the standard top fire head. Im not convinced its going to be overly different to the stock one.

as usual, thoughts and suggestions greatly appreciated. In the mean time i will keep searching this fine forum

Yes they certainly do.
However i require shipping to Australia (should have made that clearer) and they dont offer international shipping.


I have been following his threads on his new Head design and the new plenum he just released. I would be interested in testing it seeing as though reeds dont seem to do much for these engines.

at the moment they do not have a listing for an after market exhuast and their heads are all out of stock.
