Octane is detonation resistance. Higher octane fuel does not increase power unless you advance the timing, the myth that higher octane=more horsepower stems from some sports car’s ability to retard the timing to reduce the chance of pinging, or detonating the fuel too soon so that it doesn’t damage the engine. Retarded timing means less power, so when they put premium in their car it basically unlocks the full power that it has always had. Racing gas will only help if your bike/car is tuned to use it, just like E85.
The part where you talk about the oil and gasoline is a useful tip for consumers like us to avoid, I did not know much about that, thanks for the info! 👌
@@douganderson7002 lol. Tell that to Wayne. Wayne was an annoying guy who used to try and race everyone in town at red lights in his purple 4 door neon. Was fairly quick for a sohc stock girl car but a slow racecar. Until the day he went to the local airport and filled up with 100LL. He beat half the tuners in town for a couple day's until it fouled up his engine. And if you know Wayne you'll know he doesn't tune shit except his massive 747 wing on the trunk lid.
Aaron... just took our Apollo 125 RFZ X18 and Apollo 125 RFZ Open on a 60 mile trail ride in WI. Was a BLAST!! Thanks for the videos to help get them dialed in. I ended up being the hero on the trail because I brought tools! Question... for long trail rides, the seat is not very comfortable. Now sure if my suspension can be softened up... but also, have you ever thought of a seat cushion hack? Seen some people carve out the existing foam for something softer. Considering it and thought I'd ask. Keep up the great videos and ride safe!
Hey tim! Glad you enjoyed your ride and that i could be of help!! Sure glad you were the smart one to bring some tools along for the ride. Can really make or break a day! As for the seat situation i feel your pain... literally... lol Ive started using a pair of padded riding pants and those have helped me ride longer without as much pain. Without it , after 30 minutes your ass is numb. With it, i can usually do 2-3 hours before it starts getting sore. Ive definitely looked into making my own custom seat, if i was to make a video on it id want to make sure it looks nice and done correctly and wont come apart in a month or two

Any long term effects aren't really measurable. With going up on the front sprocket your RPM's will be lower at any given speed vs. a smaller front sprocket. IE: A 14tooth will be revving higher at the same MPH as a 15tooth setup.
@Jordxn. it did. I think I may have swapped it out with a 24mm. Played around with different jets after coming up with a manifold and adapting it to the carb and breather that would fit. I remember buying several and returning what wouldn't work. I may have cut the flange off of the stock manifold and used a short rubber tube with hose clamps to connect it. Haven't looked or thought about the bike in a while. I need to get the bike out and running for spring break in a couple weeks.
@Jordxn. I was too hard on the bike jumping not long after I got it going. I need to swap it for a Japanese bike that's made for abuse. Buy once cry once and don't sell it unless you're upgrading. I miss my old 97 cr250.

Anyway any help is appreciated, since i been progressing on this bike ive felt the need to have more power/speed and doing these things until i save up for a kx or crf will be great in the meantime.
Great questions! 1. The taller gearing you get the less acceleration you’ll gain. If you’re running the larger 17/14” wheelset id say stick to a 15tooth sprocket for the best balence of acceleration and top speed. If you have the smaller 12/14” wheelset id grab a 16 tooth sprocket (i will be making an entire video on sprocket choice) 2. Generally speaking most 125’s come with a 14 tooth sprocket. Are they all the exact same ( almost) The only difference between bikes are going to he the chain pitch (you either have 420, or 428 pitch) so you need the sprocket to match your chain ajd rear sprocket. Pretty sure 99% of china bikes are a 17mm spline for the sprocket. 3. That tube that used to go the stock air filter should be removed. Take the tube that comes from the engine (DO NOT PLUG IT) and vent to the the ground. That tube is ment to vent crankcase pressure. If you block that tube you will blow your piston rings.

It may change the head angle on the forks making it more or less twitchy, as well as it will increase top speed, and slightly reduce acceleration
What does that have to do with his wheels?
How much was it for your muffler i have the exact same rfz and it looses constantly cause it has no proper bolt to thighten on

Does upsizing the front sprocket damage the engine or is bad for long term
Nope! Its just changing you’re gearing!
Any long term effects aren't really measurable. With going up on the front sprocket your RPM's will be lower at any given speed vs. a smaller front sprocket. IE: A 14tooth will be revving higher at the same MPH as a 15tooth setup.
@@GromBeardo So a 14 to 16 tooth sprocket is ok. Because my dad was saying that it stresses the engine and makes it blow up
Yes you definitely dont want to jump to like a 20 tooth haha
The apollo lineup comes with 14-17tooth front sprockets
What sprocket tooth size is the best for an Apollo 125?
Depends where you ride, the 14 tooth is great if u do trails. It also depends on the wheelsize of your bike (as it affects gearing)

I lost confidence in this guy when he said don't put crappy 87 octaine.... proves he knows nothing

I still recommend non ethanol fuels tho. If your bike sits with ethanol, it’ll create shellac and clogged the fuel system
And yea, for race applications, dont use crappy 87 fuel lol unless you like detonating
@AaronsEnduro if you have detonation in a Chinese pit bike there's something wrong. These bikes don't have much compression. So anything above 87 is useless.
