whats the bigger upgrade

Just got a 78 Maxi and wondering what should I upgrade first, the carb or the exhaust.

Re: whats the bigger upgrade

exhaust

Re: whats the bigger upgrade

Depends. Which carb and exhaust do you have now?

Re: whats the bigger upgrade

Just stock right now. basically don't wanna get run over if i take this on a main street.

Re: whats the bigger upgrade

what size is the stock carb? there were a few different ones. also does your bike have a horsepower # on the side?

Re: whats the bigger upgrade

exhaust than carb maybe both. Usually you don't see a major improvement with just a carb but a huge one with an exhaust

Re: whats the bigger upgrade

its a 1.5 i'll have to go peek at the carb to figure out which one it is.

Re: whats the bigger upgrade

yeah plan on doing a few upgrades just when I got the cash

Re: whats the bigger upgrade

1.5hp probably has the 12mm carb and 12mm intake, and a thick ass head gasket. remove the head gasket, get a pipe, remember to upjet the carb, bore the intake to 14mm or buy one, and/then a matching bigger carb.

heres some manuals and stuff:

Brett Walker has a whole list of things to do to a stock maxi to get them going faster without replacing any parts, or using different stock parts. email him or search back into the past.
