Alright, so I messed around with my CRF110 a bit, tryna get it to go faster. Here’s the breakdown of what I did and how it went.
First Things First: The Baseline
Before I started wrenching on anything, I wanted to know where I was starting from. Bone stock CRF110, me on it, flat ground. I used a GPS app on my phone to get a reading. Top speed? Pathetic. Around 30 mph, maybe a hair more downhill if I tucked in real tight. Needed to change that.
Attempt #1: Gearing Change
Heard a lot of guys say gearing is the easiest way to get more top end. So I grabbed a smaller rear sprocket. Dropped a few teeth. Figured I’d sacrifice some low-end grunt for more top speed. Slapped it on, tightened everything up, and went for a ride.
Result: It did gain a little top end, maybe 3-4 mph more. But the thing was dog slow getting there. Totally killed the fun factor. Climbing even small hills became a chore. Not worth it. Took that sprocket right back off.
Attempt #2: Exhaust Upgrade
Next up, figured I’d let the little engine breathe better. Got a cheap aftermarket exhaust system off the internet. Looked kinda cool, louder for sure. Installation was a pain, instructions were garbage, but I got it on eventually.
Result: Sounded meaner, no doubt. Did it make it faster? Barely noticeable. Maybe a single mph. Plus, it made the engine run lean. Started popping and backfiring on deceleration. Needed to rejet the carb, but honestly, I wasn’t seeing enough improvement to bother.
Attempt #3: Carburetor Upgrade
Okay, the exhaust needed more fuel, so I went for a bigger carb. Found a decent one online that was supposed to be a direct fit. Bolted it on, adjusted the air/fuel mixture as best as I could by ear.
Result: This actually made a difference! Throttle response was snappier, and I could feel a bit more power throughout the rev range. Top speed increased to around 38 mph. Still not blazing fast, but a definite improvement. Worth the effort.
Attempt #4: Air Filter
Figured if I was upgrading the carb and exhaust, might as well get a better air filter. Got a pod filter to replace the stock airbox setup. Easier airflow, right?
Result: Minor improvement. Maybe another 1 mph. The biggest thing I noticed was a slight increase in throttle response. Not a huge game changer, but every little bit helps.
Final Thoughts
So, after all that messing around, I got my CRF110 from a sad 30 mph to around 39 mph. Was it worth the time and money? Debatable. It’s definitely more fun to ride now, with the better throttle response and slightly more power. But if you’re expecting to turn it into a rocket, you’ll be disappointed. Maybe I’ll look into engine mods next…but for now, I’m gonna ride it as is.
