Poor take off on 1989 Elite

[coffinhandler]

I bought a used 1989 SB50P Elite. It seems to run well. It starts quickly and idles well. It goes down the road pretty decent, probably 25 MPH. I cant tell for sure because the speedometer cable is broken. It is so slow on the take off, that it is rediculous. I replaced the two clutch shoes, put in a new belt, cleaned the carburetor with sea foam, and decarbonized the exhaust. I then drilled a hole through the baffles. I also checked air pressure in the tires. I am wondering what my next step would be. I cant imagine that it is a compression problem, because it runs so well, but maybe it is.
I would like to know what the large spring on the driven clutch does. Would a worn out spring cause poor acceleration at take off. I weigh about 220. are these Elites made for a lighter person? Thank you in advance for all replies.

how many baffles did you drill though? and was it the same way before you did that?

I drilled through them all. I would guess that engine performance increased slightly, nothing significant. It ran basically the same before drilling.

there is a small chance by drilling all of them you loose to much back compression . a 2-stroke has to have some back compression or it wont run right. i could be wrong about that being the problem but i know thats a fact.
