125 4 STROKE IMPORTS ARE NOT GOOD FOR MODIFICATIONS, IF THEY START AND GO IT IS A RESULT. MODIFICATIONS SUIT HIGHER cc 4 Strokes & 2 STROKE MACHINES.

Hi
The pulse engine is a cheap copy of a early Suzuki engine and is known to burn oil if its rev,d hard for to long a period.
You are much better of with a Honda copy engine.

you probably can, and its based on a suzuki GN 125.
there should be a washer where the carb joins the engine and one where the exhaust joins the engine too.
ive just bought one of these so if you find out post on here again, k.

you cant, its just a very slow engine based on a honda design
