The BEST 5 Ways to Modify Your Honda trx450r Atv For MAX POWER! (Cheap, Free & Expensive!)

[@F5Tornado44]

Great pointers there John. Good job. My order of mods for racing pro ATV mx is: 1. Width (A-arms and axle) 2. Suspension (revalve or upgrade) and 3. Motor

[@johnbruzzi4381]

@@F5Tornado44 revalves for a pro rider idk about that guy

[@F5Tornado44]

@@johnbruzzi4381 Yes, a revalve can do wonders for suspension, especially back in my day when there weren't many aftermarket shocks available. Nowadays replacement is pretty much the only option. Stock shocks even revalved can't compare to a set of Elkas.

Great video! Great order.

Great video man nice quad

[@MrATOMBOMB420]

The extra lift of an aftermarket cam is really not going to work like it should without porting Yes you can throw a cam in but I think you're a little backwards in the order to do these upgrades It's best to do the pipe first because if you do the intake the carburetor the cam porting all that other stuff you've still left the bike choked right down by the stock pipe Yes you can take the stock baffle out of the stock pipe I didn't hear you talk about that

[@unknown_trx]

Yoooo John my Trx is spitting oil from the crankcase breather hose what can it be I have no idea I’ve been asking and getting no answers

[@StupidFastJohn]

Is it overfull? If the vent on the valve cover free of dirt and debris? The crankcase air has to vent from somewhere!

Unplugging the TPS does not move it to a higher ignition map or anything look it up there's a 2D and a 3D map The 2D map just uses RPM as it's base 2 advanced timing a 3D map uses RPM as well as throttle position sensor to make a 3D timing map Yes it starts a little easier with the TPS connected but I haven't had any issues running the 2D or the 3D timing map It's just important when starting it with the TPS still connected you don't hit the throttle that's what kills the starting components on these bikes I fix hundreds of bikes so trust me I know these things

[@StupidFastJohn]

I did look it up and got great information from very reputable sources. The cdi does not make its own timing map based on throttle position and rpm. These 2 maps are preset locked in and have no variation in them because theres no other information being input to the cdi for it to be able to calculate anything different based off of things like air temperature, coolant temperature and such. The only reason it starts easier is because the timing is a few degrees retarded on the 1st map otherwise this wouldnt be the case because nothing else changes. This is a common issue with 2 strokes also when advancing the timing on a plate they become harder to start because of the timing advance. It absolutely will not hurt the bike to leave the tps unplugged on a carbureted bike, it will just stay in the advanced timing map. Different story on efi but the trx was never efi from the factory. The only way you can change the ignition timing within the map is to have a programmable unit installed and make your own. Stock cdi is super basic its just 2 simple timing curves.

[@MrATOMBOMB420]

@@StupidFastJohn it doesn't make its own map but the position in the map that it uses the 3D map gets its inputs from the TPS and the throttle position whereas the 2D map only gets its input from crank position It's like an EFI map it can use different parts of the map depending on the inputs

[@StupidFastJohn]

@@MrATOMBOMB420 these dont have a crank position sensor.

[@MrATOMBOMB420]

@@StupidFastJohn it uses the pickup on the stator as a crank position it has to know a crank position in order to fire it's not like a crank position in a car but the pickup on the stator is what is used as a crank position sensor

[@MrATOMBOMB420]

The 2D table clearly has 2-dimensions, the 1st being the RPM, the second being the associated value. The limitation of this type of tuning is that the tune is static - it has no adaptability. If you are over ~66% throttle, then the DME uses this table, and it doesn't care about actual load. So, for example, if you are at 4000rpm, and 0psi of boost, your ignition timing is ~19°BTDC. And if you are at the same RPM, but 15psi of boost, your ignition is exactly the same: ~19°BTDC. Obviously the load on the motor is not the same for these two situations, so the ignition timing should be different, but it isn't.solution is to change the engine-management strategy to use 3-dimensions.Now the ignition timing is no longer purely dictated by RPM. With the additional axis of load, we can adjust to the dynamic-load nature of a turbocharged vehicle. Using our example from earlier: 4000rpm and 0psi of boost, the ignition timing dictated is ~42°BTDC. And at 4000rpm and 15psi of boost the ignition timing is ~23.2°BTDC. That is a huge change from the static 2-D table in the first example.The added dimension should be immediately obvious. The 1st dimension is LOAD; the second dimension is RPM; the third dimension is the associated value.Now the ignition timing is no longer purely dictated by RPM. With the additional axis of load, we can adjust to the dynamic-load nature of a turbocharged vehicle. Using our example from earlier: 4000rpm and 0psi of boost, the ignition timing dictated is ~42°BTDC. And at 4000rpm and 15psi of boost the ignition timing is ~23.2°BTDC. That is a huge change from the static 2-D table in the first example. The addition of the 3rd-axis provides much better control and adaptability to changing engine loads and rpms. The end-result is a smoother, more linear power delivery, with multiple "secondary effects" such as economy, emissions, safety, ect.

One of the upgrades for the carburetor is to go to the Lectron smart carburetor there's also the SC2 which is smart carburetor too they use a metering rod instead of jets
