Hi..
Quick question: I just received a Joker 'Gas Cap Cover'.

http://www.bellacorse.com/bcc193.htm

"These billet aluminum covers replace the stock chrome gas cap cover and retains the stock non-locking plastic bung."

Silly question "How do I replace the stock chrome top?"

I can't see how to get it off..

Thanks!

The stock EFI throttle bodies can be enlarged to 39mm and flowed for about $500 with specialist companies which again makes it a cheaper option. My Scram is currently producing 93.5hp and 72ft/lb.

While any carb'ed Scrambler will run sweet enough, you wont be doing yourself any favours if you let some nostalgic notion of carburetors cloud your vision! EFI is the better option.
Sage advice right here...

I like my EFI for all the changes in altitude you see here in Colorado. This might be all in my head, and I am not sure how much it really can accommodate on the fly, but my bike has run flawlessly all over the state.

There's a big snap-ring to pull out that holds the threaded/seal part of the cap. You'll need some needle-nose pliers or snap-ring tool to fit into the snap-ring holes and pinch it together to get it out.

It's not in your head. I switched to EFI on our Motocross dirtbikes and have NEVER looked back. Some people will never let go of outdated technology, and that's fine if that's what they want. I'm sure someone will always still sell carb conversion kits on all brands of bikes when all brands of bikes are 100% EFI.

So glad it's ok with you.

It's all good right? I'll tune my bike in minutes with my next-generation I-phone while you futz with wrenches, screw drivers and jets. Hmmmm. We'll see who wins in the end...

It is all good but not all of us enjoy carbs for the same reason. I deal with enough computers during the rest of my life. My enjoyment comes from carburetors and electromechanical arcade games. That being said I have some uses for am iPhone ECU tuner if you have any more info one one.

Only a matter of time. If you would have told me 5 years ago that I'd be able to pack a 10" laptop in my backpack and tune my dirt bikes basically "on the fly", I'd have called you insane. It won't be long before phones are capable. I remember one of my bosses laughing at me and calling me stupid when I told him camera film would essentially be obsolete before he died. Now it's a novelty item. It just takes enough time for the old, hard-headed, geezers to die out before their favorite stuff can only be found in museums. But at the end of the day, it's all about whatever yanks your crank...

The thing is, you don't have to carry around a laptop for EFI.
Usually a pre-made map is sufficient, and effective.
Fuel injection takes 'whacking' the throttle open better. Carbs IME like a roll on better. EFI is more instantaneous than carbs albeit sometimes too instantaneous (as in modulating in corners).
Sure a built motor or perfect fine tuning could require extra Power Commander tuning on your EFI.
But the majority of time your bike will run better, sooner with EFI over carbs.
Bad tuned carbs suck fuel, pop/backfire, start poorly (different hot & cold) and fall on their face till you get it right.
Main jets, pilot jets, needles, float level. A lot of variables.
Pull off those carbs one more time!!! LOL You love it. Don't forget to sync them.
But some guys like to tinker. And some guys are truly good at getting their carbs right.
Dialed in carbs are a delight.
For the guy who isn't an ace tuner, and just wants to put on a pipe & air filter, then ride, there isn't an easier/faster way than a pre made map.
My EFI Scrambler blitzes from short shifting to redline without a hiccup.
YMMV

Yeah right, use a phone to tune...does it leave a print-out of HP and torque?
With carbs you 'll have to have the knowledge of combustion.
Now everyone is a 'self-declared' tuner LOL.
Unbelievable....
Gotta stop; my injection is ringing

True, if you have a good map to begin with. But a lot of the offroad bikes are coming into the states with EFI maps that are way too lean in order to meet our Government's insane environmental regs. If you like to tinker, it's fun to stop on a trail, whip out the laptop spend 5 minutes adjusting maps and feeling the results. Same is true of the pulse width modulators or piggy back modules like Power Commander or the JD tuners. Same concept as futzing with a carb... just a LOT quicker and cleaner and I don't even have to get off the bike.

Laugh now. I hope we're both here in 5 (maybe less) years so I can say I told you so. Cell phones, I-pads, and even Kindles already have more than enough computing power to handle the com programs and operating systems necessary to upload the data. And actually, if you've ever seen any of the shell programs used to tune EFI on bikes, the settings usually mimic carb circuits, so your argument about needing to have knowledge of combustion is still valid, even when tuning EFI. Even 2-stroke carbs will eventually go the way of the dinosaurs... ... http://twostrokemotocross.com/2011/1...ure-of-enduro/
