In search of the perfect Honda XR100 upgrades to make it quicker and extra snug? Whether or not you’re an grownup that desires to maintain driving with out breaking your dust bike otherwise you’re attempting to make your XR last more earlier than upgrading to an even bigger bike, you’re in the best place!
On this article, I’m going to indicate you the highest 5 XR100 efficiency mods that can make it a greater, quicker, and safer dust bike. Whether or not you’re on a decent finances and simply need the most affordable upgrades otherwise you wish to go all out, there are a number of choices for you.
Many of those modifications may also work on the Honda CRF100, which is only a newer model/identify for the XR 100.
5. Body cradle improve
Earlier than you go any quicker, you could wish to take into account bracing up your body with a body cradle. They could be a little pricey, but when you’re going to be leaping or doing any form of racing, it’s a should.
An XR100 depends on the stress of the engine and its mounts to carry it collectively, making it flex and ultimately break. A BBR body cradle (Amazon) provides much-needed rigidity to the body, taking the stress off the engine.
4. Suspension upgrades
Subsequent, you’ll wish to improve the suspension. Sure, you’re most likely asking why we’re not doing any “go-faster” mods. Belief me, we’ll get there, however your bike should be capable of deal with the abuse earlier than it might probably dish extra out.
Each grownup that’s ridden a inventory xr100 is aware of the suspension is less-than-satisfying. In two phrases; it blows. Actually, it bottoms out simply driving over bumps for those who weigh something over 140 lbs.
Low cost fork improve
Heavy-duty fork springs (Amazon) are an affordable improve and could be swapped out at dwelling with some fundamental store instruments. They’re claimed to be 30% stiffer than the inventory springs, which is greater than sufficient for those who’re 150-180 lbs.
Actually, it could even be too stiff for those who’re simply path driving. When it’s too stiff, each bump will really feel sharper/harsh and also you’ll get fatigued faster.
Professional Tip: If including each BBR springs is just too stiff, then take away one and use one OEM inventory fork spring. This can cut up the distinction and solely make it 15% stiffer than inventory.
It’s also possible to use heavier-weight fork oil (Amazon) to extend the damping, which provides you a little bit extra management when the forks are compressing and rebounding, in addition to stopping bottoming – particularly for those who increase the fork oil top.
Low cost shock improve
A heavy-duty rear shock spring (Amazon) is even much less however is simply as necessary – particularly in case you are going stiffer on the entrance forks. In case you don’t have the entrance and rear suspension balanced, then you’ll have poor stability and/or traction, inflicting you to clean out extra simply.
For lower than 200 bucks you’ll be able to have an xr100 that rides significantly better and is prepared for these “go-fast” mods.
Upgraded rear shock
Need one thing higher than only a ‘stiffer spring’? An aftermarket Vonkat Fats Boy shock (Amazon) is an inexpensive option to get an adjustable and far better-performing rear shock.
Not solely will it carry out higher than a inventory shock as a consequence of its damping adjustment, however you can too rebuild it. Meaning when it will get worn out, you may get it serviced in order that lasts longer as an alternative of simply throwing it away.
Fork conversion improve?
The inventory damper rod standard forks are troublesome to switch except you’re properly skilled with how any such fork works. A preferred, but a lot greater mod, is swapping the inventory forks with entrance forks from a Honda CR80.
It takes some customized modifications and fabrication work to get them to suit, and also you even have to boost the rear finish to get the bike balanced for correct dealing with. Supposedly, a 1982-1985 CR80 front-end is near a bolt-on mod.
The newer rears require steering stem mods and a whole CR front-end as a result of it has a disc brake. You’d nearly be higher off placing the XR100 engine in a CR80/CR85 body with higher suspension already.
3. Consumption mods
Like many different issues on this dust bike, the consumption is extremely restricted. Honda XR’s run wealthy from the manufacturing facility, however that may be fastened with a greater air filter and jetting arrange.
Excessive-flowing air filter
The inventory foam air filter works, but it surely’s not made for efficiency. Merely put, an aftermarket UNI Air Filter (Amazon) replaces the inventory air filter and provides your XR100 higher airflow, which is required if you wish to make extra energy whereas nonetheless maintaining dust out of the engine that can put on it out shortly.
Simply bear in mind to grease the air filter earlier than putting in it in order that any dust or particles sticks to it. In case you don’t correctly oil it, the dust will get sucked previous the filter and into the engine, which can trigger a failure before later!
Pod filter – is it price it?
Swapping out the whole consumption system for a pod-filter (Amazon) can be the least restrictive and supply probably the most energy acquire, however I wouldn’t suggest it except you’re doing supermoto with the bike. It’s out within the open, so it’s extra inclined to sucking in water and dust.
Free/low cost airbox mods
A free mod you are able to do is drill a number of 1/2″ or 1″ holes across the airbox. This can enable extra air to get in and to the engine.
In case you’re nervous about dust getting by these oils, then you need to use some Uni Air Filter Vents (Amazon)
It’s also possible to pull off the air filter and take away the backfire display on it. It restricts airflow, and an xr100 has little or no probability of beginning a fireplace by back-firing.
Nevertheless, achieve this at your individual threat. I’m not liable in your personal actions.
One other frequent consumption mod that xr100 homeowners do is substitute the carburetor with one from an ATC200X. That’s proper, an outdated Honda 3-wheeler.
An XR200 carb will match as properly, however the 200X is probably the most as a result of it’s a barely greater bore than the XR100 carb (24mm vs. 22mm) and bolts straight onto the xr100. If the throttle cable is just too lengthy, simply purchase one from a CR80/CR85.
The 200X carb will probably have to be taken aside for a cleansing, so that you may as properly re-jet whilst you’re there (or get a tough estimate on the place to start out).
Low cost inventory substitute carb
Possibly you simply want to interchange your inventory XR100 or CRF100 carb as a result of it’s been sitting for therefore lengthy and received’t begin. Whereas I don’t usually suggest low cost knock-off carbs, this one from Amazon has fairly good scores and is an inexpensive option to get your Honda 100cc dust bike working once more for those who already tried cleansing your unique carburetor.
Jetting – the forgotten mod
A standard mistake is modifying or upgrading the engine or exhaust and never altering the jetting. Not solely are you lacking out on extra energy, however it might probably truly injury your engine if the jetting is just too lean.
By spending a little bit time adjusting the jet circuits, your XR100 will begin simpler, run smoother, make extra energy, and last more. You may get began in only a few minutes with my Free information right here.
Inventory Honda XR100 jetting:
- Pilot jet: 35
- Needle: Center (third) clip place
- Major Jet: 98
Jetting with uncorked mods ( place to begin):
- Pilot jet: 38
- Needle: 4th clip place from prime
- Major Jet: 105
2. Exhaust improve
Simply wish to make your XR 100 louder with an affordable however nice-looking muffler tip? This Billet Tip & Spark Arrestor (Amazon) is an inexpensive option to get extra noise that sounds higher.
This solely suits in your inventory XR/CRF 80/100 muffler if it has the detachable finish cap/baffle. Because of this it ought to work on all mannequin years 2001 and newer.
Extra energy along with your sound
An FMF exhaust (Motosport) is a comparatively low cost and simple option to hop up your XR100. Not solely does it open it up for extra energy, but it surely sounds rather a lot higher than the choked-up inventory exhaust.
Nevertheless, for those who journey in a noise-conscience space, you may wish to take into account maintaining the inventory exhaust on. Any aftermarket muffler or system will make your XR or CRF100 a lot louder, which might lead to neighbors complaining.
Race exhaust that’s not FMF or PC
Don’t need the favored FMF or Professional Circuit pipe that everybody else places on their XR100 or CRF100? You may get a Huge Gun Evo Mini exhaust (Amazon) that offers you a little bit extra energy potential.
The one downfall is that it’s fairly loud, so I don’t recommend putting in it for those who’re driving in an space that may get noise complaints from neighbors.
Do you’ll want to re-jet the carb with an exhaust?
It’s possible you’ll not must re-jet the carburetor with simply an exhaust, but it surely is determined by your local weather and present jetting specs.
Most often, your XR100 will want some jet tuning, particularly if it nonetheless has the inventory jet sizes and for those who’ve completed the earlier consumption mods to make it run easily and get probably the most energy out of the modifications.
1. Engine upgrades
One of many best methods to get extra torque and horsepower out of your XR100 is to offer it an even bigger engine. By including a 120cc large bore equipment (Amazon), you’ll be capable of speed up quicker to stand up hills faster or pop the entrance wheel as much as wheelie over logs with much less effort.
A giant bore equipment merely replaces the inventory piston and cylinder. It comes with every thing you’ll want to rebuild the top-end, so if you’ll want to rebuild the inventory engine as a result of it’s smoking or worn out, this can be a no-brainer deal.
Is a giant bore equipment dependable?
This actually is determined by the elements, how they’re put in, and the way properly you keep your dust bike. A giant bore equipment can truly be extra dependable than inventory since you don’t must rev the engine as excessive to get the identical acceleration.
Give it some thought – the much less RPM, the much less put on and tear on the engine.
Widespread errors that make a giant bore unreliable:
The inventory camshaft could be very tame, which is ok for the inventory engine. However for those who upgraded to a giant bore equipment and better-flowing exhaust, then the inventory cam goes to be limiting energy – not providing you with the compete efficiency that you simply hoped for.
Utilizing a Scorching Cams Stage 1 camshaft (Amazon) is a fairly inexpensive option to get noticeable extra torque and horsepower all through the RPM vary. In case you’re planning on rebuilding the highest finish, an aftermarket cam is simply as simple to put in because the OEM camshaft.
The best way to get probably the most energy out of your XR100
Earlier than you do any of the final three mods, although, you must know that in an effort to get probably the most out of the bike, modifications needs to be completed to all of them.
In different phrases, you’ll acquire much more horsepower for those who open up the consumption AND get an aftermarket exhaust, as an alternative of simply doing one or the opposite.
You may get the cylinder head ported, shaved, and/or blueprinted for those who’re seeking to maintain inventory displacement. If you wish to go all out, there are “Tremendous Head” kits that include a whole top-end, together with a bigger cylinder head with greater ports and valves to extend airflow.
For this type of cash you possibly can purchase one other dust bike, however, for those who’re racing it in a extremely aggressive class and have a whole lot of further money, I’m positively not going to cease you.
It’s not a race bike, however…
Ultimately, it’s going to take both some huge cash or time (or each) to make an XR100 aggressive on the motocross monitor. However that’s not what an XR100 is meant for; it’s a enjoyable, yard, play-bike.
When you have the mechanical skills and motivation, try my finances xr100/rm80 conversion construct for some concepts on how you can construct the final word pit bike for adults…
