Small injector

Post by old guy »

If someone is looking for an injector for a small single cylinder engine the one from a Honda Grom might fill the bill.
Honda part# 16450-K25-901 and available online for less than $40 online. No idea what the flow is , but the engine is only 125cc so should be pretty small. Would need to do a test to figure the dead time so finding the lbs per hour should be easy.
It also has a pretty cheap throttle body which is 23mm, but can be bored to 28mm.
The only downside is that it has what looks like an iac valve but is just a valve controlled by oil temp to step up the cold idle. Also no tps,but I understand some of the Euro ones do to meet there epa standards.
