deristricting

[ldnicholas18]

are dna 125's restricted and is it easy to deristrict if possible

[chillpill]

restricted by there shitty 4-stroke engine , whack a 2stroke runner lump in there

[ldnicholas18]

so are you saying that they are just slow anyway and would the runner engine fit straight in

[frez]

There is not much you can do to improve the performance of a 4-stroke 125. A different exhaust may improve things slightly, likewise a different carb, but you are talking minor improvements.

2-strokes can be derestricted to yield massive increases in performance, the theory of 2 stroke vs 4 stroke being that you can get twice the power ('ish) because the 2 stroke isnt wasting half the revs expelling exhaust gases.

You can get a 210cc kit for the DNA, that would improve performance I imagine.

yeah man , if they were any slower people would die of old age driving them home from work

runner engines fit almost straight in , instant power gain and also alot more tuneabilty , 172 kit 25mm carb and an exhaust to match , with a 180 transmission would be pushing close to 20bhp , or you could just put in a standar 180 lump if you dont want to go mad with the tuning, would hit 80mph and would be reliable

dont bother tuning the 125 four stroke engine , 210 kit costs over 200 quid and if turns your crank to cheese there expensive , a bigger carb is something ridiculous like 100 quid and an exhasut is 200 + , a vxr 200 engine would cost the same or less than a 210 kit and would come with a carb and transmission to suit

is it wise to tell the insurance if an engine change was done and how much would it go up by???
