Kinroad XT50 GY / 50cc Enduro

[dervdub]

They do run a pit style engine judging by the picture.

Not sure what cutting wires will achieve if they run a normal pit/monkey CDi

If you want to make a 50 noticably quicker you need to up the capacity 72 or 88cc kits are a direct fit, bigger carb, better head (or gas flow the one you have) and possibly a better exhaust if the stocker is really restrictive.

Or just drop a bigger engine in

[mysterious_rider]

ah yes! you would be right.


Yeah I'd say.

Bigger carb. The stock one is probably what, about 14mm? up it to a 18mm or something.

exhaust (again only if its very small bore and restrictive, it might not be, leave this till last)

dont bother changing or cutting wires on the cdi though. Makes no difference.

As above, a 88cc kit would probably be the best thing for performance.

To be completely fair though mate. If you start with bore kits its starts getting silly money, drop a 110-125cc pit engine in there (probably a straight swap) and a cheap second hand 110 wont set you back more than £75. Just grind the CC off the head.

Cutting wires I have done too many cdi's, these cdi's are resticted, the restriction controls the rrpm. This will make the bike do a extra 5-10 mph.
Please if your not sure or dont know, dont give out bad info and just for the record its a 6 pin. The bike will be road legal so bigger engine is out of the question. I do intend to re-jet or replace card and upgread the head to a 70cc

if ur putting to a 70cc its still ilegal so why not just put a 125 in it and grind the numbers off

[oliver_125]

you actually need to put a 88 kit or whatever on because theres one in the shop near mine an even a minimoto can beat them there so slow

i hope you do upgrade it because youve prob rode it an no how slow it is?they are SLOW

[SkyteamST125]

My first bike was a chinese enduro with a 50 pit engine, now its a 150, but heres what I did to the 50 that was actually worthwhile

Change the sprockets, they gear them stupidly to do 30
Change the ****ty chinese spark plug & cap for an NGK one right away. It'll cost you about a £1 and the bike'll run so much smoother, start better from cold, accelerate quicker, rev higher, chinese spark plugs really are terrible
Mine had a huge washer with a tiny hole in the inlet manifold, drill it out and instantly higher top end and acceleration (top end only because it revs higher)
Bigger carb & K&N,

Race CDI did nothing on mine, so not sure if cutting the wire'll give you much difference

you are deluded why would u bother to make your bike illegal buy putting a 70cc kit on which you wont notice much diffrence when you could put a bigger engine in either way your going to be illegal but with a bigger engine u will have more fun better speed and accelaration

[dervdub]

Ignoring the legallity of engine mods:

Get a pic up of the CDi - I'd be really suprised if it runs a different CDi to Pit/Monkey motors, they have 6 pins, only 5 are used.

The way the generators/ignition works is that the rev limit (if there is one) is in the CDi and it's hard coded if you like, cutting wires won't do anything except maybe stop it sparking, the advance/r3tard circuit is controlled by the length of the pulsar pickup trigger - this bike could well be different though - a pic would help us work out what you have.

I think your deluded mate I have been making bikes go faster all my life.
Why buy a bigger engine, I can have made 70cc bikes go faster that 125cc
Its all power to wieght "mate" Just cause an engine is bigger doesnt mean its faster. I might consider a 125cc if I was using it in a field, but piont taking about the legality.
