@SiMoNsKy22 different gearing and flywheel weight... My YZF gets up and goes a bit faster than my dads WRF and his is 5 years newer... I think the YZF with the standard gearing is a lot closer to the power of a 2 smoke 125... yes they still are both 250s though
@schoolace Yeah 4 strokes are roughly doubble the cc of their 2 stroke equivalent i knew that, the WRF has he heavier flywheel for a little tiny bit more torque as the wrf is used in enduro bikes mate
This track is too short to show the full potential of these karts, is a sprint track and those do not look like 250 to me more like 125, but then again karting engines changes like the wind, I might be wrong !?
In fact, Yamaha makes a verry limited production of this excelent motor, 100 units per year aprox for all countries , here in mexico we have an omologated category with at least 26 karts with this engine,in must of the cases we overhaul the engine every 3 years with out loosing power in this period, it has electric starter and digital ignition, any 2 stroke motor is far away on technolgy and reliability, this motor produces 43HP stock using street fuel.
in karting, rotax 125cc ( 2 stoke ) have to be rebuilt every 50 hours max. my 250cc biland (4stroke and same speed as rotax) every 300 hours.... 6 hours with a normal 2stroke icc and this will be 600 hours before rebuild?
personaly i like the sound of the 4 strokes way better than 2 strokes ,and 2 stokes need to be rebuilt after 50 hours of racing 4 strokes can go longer, unless of couse your building them like some of the builders for huge motocross teams.
Yeah but if a piston in a 4stroke blows to pieces it would most cerainly cost you 788450 billion dollars to repair the valves and alot of other stuff, in a 2 stroke you often get lucky enough to just need to replace the piston itself.
Actually I have delt with 2 & 4 stroke motors. With 2 strokes, after a certain amount of use ( miles) you have to break down and check the internals, something you don't have to do as offen with 4 strokes. Also on cold starts, 2 strokes are harder to start....
im from aust. i heard that the 4 strokes are becoming faster. i prefer the 4 stroke it is much easier to drive. is their and world compitions u can compete in? im only 15
Yeah they are... atleast on the motocross bikes. The 250f's are putting out almost as much horsepower as the 250 2-strokes now a days. I think the crf250 is something like 6 horsepower off from the cr250
that 125 shifter thats running ahead of the 4-strokes sounds awesome..wonder if its a stock moto or icc, damn! sounds like its not running a silencer, it echoes around the track
hows it do against a good 125 kart? i have CRG roller that was given to me and im not gonna race it just play and take it on practice days with my friends who have vintage karts and im leaning towards a 4 stroke 250 just to be different.
les 4 temps ont l air de bien tournée mais au niveau du bruit !!!!! le 2 temps pfffffff incomparable!! en plus quant ca résonne dans la valée comme ca pffffff ca me fou le brak ha hahaaahaa!!!!!!!!
memo is 1 of the coolest guys u will ever meet. he co drove our lmp1 car at petit lemans in 2006 for highcroft racing. i spent a week with him in the shop, and at the gym. He really is the best at karting!!! if u can learn from anyone its this guy!!!
Yes, they do make a paddle-shift conversion kit for shifter karts. I can't really see too much advantate to it other than looking really trick, and it IS legal as far as I know in all shifter classes. Look at the video. You can see very little hand movement with the standard shifters.
I dont think you can get a four stroke kart, but you could probably get a gearbox chassis and then put a 250 four stroke engine on there, but a 250 two stroke is much faster.
BLEH!! A 4 stroke? why? Everyone knows 2-strokes are faster for Karts. I'd like to see a 250 2-stroke against a 250 4-stroke. The one that the guy behind him is racing is a 125. of course he's not gonna win. He's got a smaller engine. All this 4-stroke bs. I'm sick of it.
they dont do 150mph u peanut... altho the superkarts do,, not these ones tho... still very very fast! i had a 100s, just got my 125 shifter last week tho
