A boost?

[senorpyz]

I recently have finished my 1st build, a thatsdax 66 cc kit on a Schwinn Delmar. It runs great but I want to get a little more power out of it. Any suggestions? I also have been wondering if anyone has run across a bigger engine?

Edit:
I have found some parts that are what I'm looking for. Maybe you guys are interested too.

Above is a cylinder head cover for $13. One review said that it increased his top speed by 7 mph. Sounds like a cheap upgrade.

Here is a racing style carburetor that is a bit pricey but sounds like it gives you a major boost in power.

guess you want more speed -- different type of motor may be best

if you get a Japanese motor and soop it up -- you really have someTHING

the little Happy Times are only going to take so much -- until they blow apart

ride that thing

Yep,
High compression head and a sick bike parts shifter kit will get you hitting 40mph easily.

Break it in first, then see what you want to do.

where can i find a japanese motor?

also, will the slant head cylinder cover from zoombicycles work with my engine? (the one found in the thatsdax kit)

I would order two cyl base gaskets: Zoombicycles Motor Bicycle Gas Engine Kits 80cc Cylinder Bottom End Gasket (A-7) | 10-Gaskets | 6-Parts and Accessories | RuiHong Enterprises Ltd., and one on their head gaskets: Zoombicycles Motor Bicycle Gas Engine Kits 80cc Head Gasket (A-3) | 10-Gaskets | 6-Parts and Accessories | RuiHong Enterprises Ltd.

i found this written by justin on another thread from a while back concerning the slant head cylinder covers. I am not the most knowledgeable person when it comes to motors so I am not exactly sure why he is suggesting to buy new gaskets if you plan on buying the slant head cylinder cover.
