New Subject: High End Speeds

Got new motor, runs great!

One thing I noticed:

the new one can go 30 easily with no vibrations, on the high end it the engine runs great no vibrations, it just kick in and goes faster, whistles but the engine isn't overheating or too high of RPM like you might notice at full throttle when idleing

the first bike when going full throttle rattles at about 25 and the engine sound like the RPMS are too high and if you were to go at full throttle the parts would shake off.

Since its the same two bikes and same engines how do I get the second one to kick in and put out on the high end of the throttle?

wow, i have the reverse situation.

my old engine, i didn't get a good mount ( rubber mounts suck ) was awesome, so much torque low>mid and all the way to full throttle. New engine has no guts whatsoever and has a whistle whining sound.
 
Hopefully, proper 2 stroke oil was used, I'd rock the con rod, to see if it moves freely.
If correct oil was used, and crank is good, cylinder may have been poorly fitted at factory. Good luck on the Warantee, most vendors will try to pass it off as ' your problem, not mine ' Considering the lousy quality, vendors should be more receptive to factory fubars. The concept of tearing down a ' new ' engine, to see if was built right, is insane, but prudent. Before buying, ask vendor if they recommend a pre - fire up teardown, and if they honor warantee if [ when ] problems are found.
