Dude that isn't a 90cc kit, first you would need to change the crank for a 90cc stock one can't handle he power and the stroke is to short 2nd, stock exhaust system can't really be used to big exhaust port and no way the stock carb works for 90cc... It's a 70cc cylinder if I had to guess
@@lewisseward3261 Maybe you shouldn't be wrenching too much on bikes if you thought you could just bolt on a 90cc kit without changing anything else....
55mph with a 90cc kit? Something ain't right bout that, I have the same and am hitting 60 with stock 50 head, not tried up gearing?? Best is a 15/16 tooth front sprocket, up jetting it aswell, run a higher main jet and tune the mix
There is no "90cc" lit like this he got scammed or is lying to us.. sites where you can buy real stuff is scooter attack, maxiscoot, twostoke there is probably more sites just the once I had in my head
@@hugoglaes6813 Hey man i randomly stumbled across this video you probably won't even read this let alone reply to this but anyway i have a 2017 rieju mrt 50cc (off road version) and its completely stock, I've been thinking about it for a while now and im wandering if i were to upgrade the bike what would be the best option to go with? Im talking more in regards to the 90cc or 75cc carb/big bore kit thingy idk much about it lol all i know is that it will give me more power and probably drain alot more fuel other than it being illegal for me at 16 yrs old (technically) are there many more downsides to doing that upgrade e.g the bike not being able to handle the power? Anyway long story short if you could give me any information regarding what sort of carb/big bore kit upgrade i should do to my mineral am6 rieju mrt 50 engine i would be so, so grateful. Thanks!
Everything But Normal Productions lol of course you have to do it you need to re-align the piston with the crank. It’s not a hard task. If you plan on going 80cc + make sure you upgrade your crank or it’s just going to break within a few months
Its a 90cc top end, so not much to the engine. And definitely a increase in power. Thinking of increasing the Carb size. But I will be uploading a new moto vlog today so make sure you watch that. :)))))
The piston in that is 49mm in a 90cc u normally use a 52mm piston
It's not a 90cc big bore by the way it's a 74/75cc cylinder

its the exhaust. That exhaust sucks its the original
15-16 front sprocket with all the restrictions i don’t think so, maybe 12 Max 13 when u change exhaust or the ECU or Both then upsize your sprocket
you need a bigger carb and a matching 90 pipe
is that the stock exhaust on a 90cc? You need a different exhaust!
Flammable crutch, sound fun.
What's the name of the bag on the back
Aye where did u get that speedo meter from or was it stock
stock
What year of rieju is that
could you link me the big bore kit you have or reccomend any others to me please?
Just type in eBay am6 90cc should come up

Do you still ride it?
Does it come built or do you have to do it?

Steve Mad ok thanks
Everything But Normal Productions no probs, you don’t have to upgrade the crank but it’s a lot of stress on the top of the engine.
I had to fit the big bore kit
I’ve got Straight 49cc not kit, de restricted And I can get 50mph
Nice! Any changes to the engine or just a bore kit? because of the increase in power?

Changes that has to be made for a real 90cc would be a stronger crank with a longer stroke and a bigger Carburator
And a performance exhaust would be ideal because the stock one is garbage
and a larger carb
Derestrict the pipe
Please remove the S.A.S that'll be strangling your engine. If not get another exhaust. Lovely bike fella.
Only getting 50 out of a 90 kit😭
Mine has a 80cc kit and hits 140kmh im going to get a 90cc
