Question by Mitch T: What are some ways to de-restrict a 100cc two stroke quad bike?
It is an apache 100cc 2 stroke engine which has had the throttle re stricter removed, that is the only mod that has been done to the bike.
Basically i just wondering if they are any other ways to get me a higher top speed?
Answer by junior
There may be a restricter washer in the exhaust head pipe. Remove the exhaust from the cylinder head and look for a piece that looks like a washer.
Also, the manufacturer sometimes installs an ignition module that has a rev limiter. There are “no rev limit” modules available that will increase the top speed, but I’m not familiar with your bike, so I don’t know where to find one.
What do you think? Answer below!
