Maf 71cc (63cc) engine coil upgrade

How to to fit a derestricted coil to the Maf 71cc (63cc) engine. The original coil is limited to 9.5k rpm. It involves having to advance the timing of the flywheel

[@christianhamer1665]

Thank you so much. I was trawling forums as to fit an unlimited coil and came across your video. I have this engine fitted into a X2 pocket bike with a CVT transmission. The bike is extensively ported with big carb and race pipe but wouldn't rev past 6k . Now it screams and goes like the clappers. Top man.

Did this to my 1e53f engine and it works on that aswell.

i like your tutorials alot because you cover everything. can you please do a porting tutorial on a 49cc 2 stroke pocket bike engine please, thx!!!

[@mariorivera252]

Im curious about if you time the motor wrong what it would sound like. Im not sure if i got it correct

[@jaze4971]

I've got a 63cc as well , looks exactly the same.I tried this and I am having trouble with it slipping, also the fly wheel to get the position would be moving it like 3or 4 over compared to your 2 fin adjustment? Any help or advice ? Could really use it right about now...

[@jasoncrowley4870]

Is there a link for this coil upgrade I can't seem to find it anywhere

[@jaze4971]

If I bought the unrestricted coil and do I still have to adjust the flywheel ? I have so many questions. I wish I could actually talk to someone on the phone .

[@treejay818]

How many rpm does it reach with new coil?

i hope you have a full tutoriasl on porting bro

[@frankg3278]

Every 2 stroke engine is different and needs to be ported differently so it's difficult to do. It also depends on what you are aiming for when you port. Generally, when you port, you shift the power into the upper rpm range.

Hey Frank I just bought a copy cat 63cc of the kasei could you tell me if it's about the same thing?

[@57xcustoms44]

I couldn't get a real kasei.

[@frankg3278]

Has it got 1e48f stamped on it?

[@57xcustoms44]

@@frankg3278 haven't got it yet but it says in the description that I'm getting one 1f48f engine. Looks identical. It conning from aliexpress.

Thanks I appreciate it. I'll let you know how it works out.

[@mariorivera7293]

How will you know if you’ve timed it incorrectly?

[@frankg3278]

Too advanced and it’ll overheat, start pinging and loose bottom end. Too retarded and it’ll be sluggish

[@TylerHartman]

I'm thinking of importing ten 1E53F (79cc) engines! I would offer to sell one on to you for the wholesale price. (around $55 USD) Would you be available to give me advice such as Carb setup, porting and coil upgrades?

[@frankg3278]

I’m in the UK. I don’t know much about the 1e53f

[@HighMileageOffroad]

Do you have a link for the coil you used and the flywheel! thanks

[@frankg3278]

Standard flywheel and watch until the end

is this applicable for installing no limit coils?

Yes

What coil u changed bro?

[@frankg3278]

Watch until the end

[@obet270]

Did you remove the rocket key? Why?

[@frankg3278]

Yes, because the derestricted coil requires the timing to be advanced

[@montehuseby1640]

This is much better than the factory ignition setup, but the 460 coil and flywheel does perform better. The flywheel is lighter and the timing curve in the coil is different and more favorable for high rpm performance.

[@frankg3278]

Depends on how much you want to polish a turd. How much does that additional hardware cost? It's £7 for this coil. These engines cost £100

[@montehuseby1640]

@@frankg3278 hey man I don't disagree with that at all. I do have to lend these engines some credit though, they can be dead reliable when set up right and they make great power. My current reeded 63 setup pulls 14,210 loaded rpm on flat ground. Some 460/ 470 setups may rev a little higher but they will never be as powerful or as satisfying. I will still recommend a 460 to a beginner though, a good 63 setup is more of an advanced level builders engine
