The exhaust is not replaceable with an aftermarket product and has to be cut open to remove baffles then re-welded. The air filter is an easy swap for freer flowing jobby. Advice on polishing head (ooer missus) and lightening and balancing crank, pistons etc please. Also carb jetting advice would be nice.

Depends on the engine and if its been used for competion at anytime. Honda125 can use parts from the XR range, including big bore kits(150 cc is 'standard) Suzuki can use some parts from DR200. Bigger carb will jhelp top end but you loose some on the botom end. The ports need to be matched to carb if you go oversize
