Harbor Freight 2.5hp mod questions

[TheOtherStyle]

I did some searching to see if anyone here had done any mods to a Harbor Freight 2.5hp, and other than Znsane (who I know on a different forum) I've not found anything really.

I'm planning to buy one probably next month, and I know I can remove the governor, remove the muffler box to make my own exhaust, and replace the air filter box with something less restrictive. I think I saw mention of replacing the carb with one from a 3 or 3.5hp engine (brand unknown).

What other mods are there that would work or possibly work? Any cams, intake or exhaust, ignition, or other mods?

if i remember correctly it's another clone of an old honda just like the 6.5 .
i've seen a couple bikes on you tube with the 6.5 the 6.5 is like jello there's always room

Can't say I recommend pulling the gov on a clone motor. High flow air filter(UNI) and exhaust will wake it up a little.

^^ That's what I'd do. Be prepared to rejet or drill the jet due to the inscreased air flow.
