ame amazonas 250 engine swap

[someone]

hello ,
Well i got me a nice ame amazonas 250 with 2000 km in the gauge and for 6+ years looks almost new from an older guy with many motorcycles sitting around .

Anyway this motorcycle is a loncin lx250-7 without becoming boring its basically a chinese heavy motorcycle with 1:1 copy engine of the GN250 in a larger frame.

the problem is the that a heavy motorcycle + a heavy rider with a tiny engine that thing cannot do anything more that 100km/h while the engine is screaming.

i tried looking around i can change the head to gn300 but 6hp isnt worth it .
Gn400 is rare to find anyway.

SO can i fit something else like a LTZ400 engine .or any other engine.

it have a dual disc front brake with 2 pots each cailber ,and a heavy steel frame .

i really like the bike and am trying to avoid to replace it with something else.
am not looking to drag race it ,just to be highway worthy

thanks alot

Its a Loncin LX 250-8, not 7.

You probably won't get anything special to fit in there to be honest.

I presume its an air cooled Suzuki single? If so a 30bhp DR350 engine might be pursueded to fit even if you have to modify the mounts or the frame rails under the engine.

Where in the world are you based?

It's a 250 so if you have a licence yo ride it, as is you have licence to ride an awful lot else, as is, that need no effin about with.

The old GN250 made about 25bhp OTMH, it were no tyre shredder of a motor, & I very much doubt that a chinky clone made on half worn out tooling from recycled coke cans makes even that...

40bhp? Yeah.. Oh-Kay... take rather more than a turbo to get that sort of oomph from in!!! And if you blow it... why on earth are you worried about it's head 'breathing'? That is sort of the point of forced induction... if the head dont flow, you just turn up the wick a bit! Seems you dont just know not a lot about bikes but engines either, do you really believe you have where-with-all to try get almost double the power out of this poor little cruiserette mill?

Bottom line; there' plenty of engines that make about 40bhp, and with a big enough hammer, welder and angle grinder you could make any of them fit that frame... But WHY?

End of the day it's a chinky cruiserette... its a wonderful way to make an already not so valuable bike even less valuable, harder to insure and likely no better on the road for it....

So what do you 'like' about the thing, and what, could you buy off the shelf that has it, no spanners required?

To my mind the default 'My First Cruiser' is the Yamaha 535 Viagra; that has the 40-ish bhp you say you think you need; they are hardly rare or expensive, so for less money and a LOT less hassle, you could pick one of them up in as nice a nick and it'd likely keep its shine longer too... or any of the alternative small/mid range Jap cruisers; Kwak Eliminator perhaps, or Honda Shaddow... heck for not a lot more money and still less elbow grease, real deal 883 Piglets are hardly beyond the bounds... though I know you reckon you need 40bhp... lol....

End of the day, its a Chinky Cruiserette.. it is not a fast bike.. weight dont much come into it.. speed is power vs drag and drag is frontal area not weight.... acceleration is another matter, and there force - mass x acceleration, so heavier it is less brisk it'll be, but then thats the nature of the beast... if you dont like that, get another bike you do!!! Like a Shaddow, Eliminator, Virago, or heaveen forbid the real deal baby Harley..

Or just enjoy what you got for what it is.. a #cheap' harley-esque cruiserette.

to avoid keep getting off topic

yes i can work with tools if i got stuck i can use the help of a local motorcycle shop if i bring them the required stuff.

the last time i owned a motorcycle all motorcycles had carbs and abs was something unheard of in a motorcycle.
So this bike is not the one. i just need to get the muscle memory back get my skills refereshed without having to drive an ugly cg125 or get a bigger more expensive bike that i will lose some amount of cash when i decide to get the one .

i dont want to buy some one else headach , yes there is alot of older hondas suzuki etc etc very cheap and hardly road worthy.

engines on the other hand can be bought in good cond. cheap from older bikes with very less miles, from bikes with paper issues such as being not registerd for a very long (at least where i live) and its 100% legal

i like the bike i just want a little more juice out of it.

Thank you everyone for your input

So i talked to a guy who used to work for their local dealer when they had one .
And he told me that loncin use or at least used a universal-ish frame for most of their bikes and since they were shipping diffrent engine sizes as per their dealer request, there frames have enough room for upto 650cc suzuki single cylinder without any issues maybe just the fuel tank.

this is if anyone is looking for this information .

As for my self if i find the right engine for a good price , why not !
