1st gear........attain 40kmph or the maximum attainable speed with normal clutch release,(dont dump clutch in this run,you are not gonna wheelie or drag) without stressing the engine(minimize revs at redline).
2nd gear........attain 60-65 kmph or the maximum attainable speed with normal clutch release,without stressing the engine(minimize revs at redline).
3rd gear.........attain 85-90kmph or the maximum attainable speed with normal clutch release,without stressing the engine(minimize revs at redline).
4th gear.........attain the top speed attainable with normal clutch release(minimize revs at redline).

Then you see your engine would be on its own.You wont feel to complain about performance.The parts harden without stress and then needs to be tempered with mild stress.Hope this helps.

Yes, one will have to vary the speeds during run-in itself. 3rd gear 85-90Kmph on a stock 4-speeder is impossible, even with 90 degree down gradient !!!!. This is for the info of the owner of this thread.

@ MACH50 thx for the detailed info. My Rx is still a 135 cc and it is a stock bore. No Modifications. Sorry I don't know about the carb settings and No porting stuff. The bike got new stock bore and it replaced the old bore

One thing i would like to tell you here, a brand new Piston-Cylinder kit wheather run-in or not should give you a punch, if not the 100%, but atleast 70-80%, coz its an RX & not a Luna !!!

Have you checked the condition of crank shaft & clutch assembly ?

Were the engine bearings replaced ? Rather was the engine opened at all ?

Engines are nothing but moving mechanical components, so it cant last infinitely. You have not mentioned anywhere as to how old is your bike ?

Which silencer is it running on ?. You would need to de-carb it if required, replace the air-filter with a free flow one & then you will see the difference.

You have mentioned it was re-built, request you to kindly elaborate.

With Regards,

Thats why I said "or the maximum speed attainable......." , the only 2t I ride is the Shogun,so my figures may vary.....
