Firstly, welcome sir 🙂

This may go over your head but please trust me,  can you do the following below  first

• Let it get hot for 10mins.  Then do a compression test.
  Tell us what PSI each cylinder is , on full throttle. both plugs out.
• Can you allow the bike to get overnight ice cold (required) then wake up , do a clearance check with a feeler gauge by taking valve covers off.
  Tell us what each valve says,
  eg.  Exhaust Rear (sprocket side) = 0.26mm
  eg.  Exhaust Rear (cam chain side) = o.28mm
  eg.  Intake Rear (each side) = 0.13mm
  Repeat
  This
  For the front engine.

  I will upload more manuals on the site when i get time.   In meantime, checkout manuals lib site for “GT125 Service Manual” and follow instructions on how to test compression or clearance or let a garage do it real quick and get proof on paper. Don’t trust their lips.

• Also,
  While at it, check your clutch plates with a VENIER CALIPER and measure thickness of each plate.
  Also check how long the spring is  (standing) , don’t compress a clutch spring.   Eg. springs x2 35mm and other springs 32mm long etc..

What i said above, is critical to hit the 80 mark,  otherwise the bike won’t do it no matter how tuned it is. So to save you money buying random things. Lets make sure the engine itself is healthy with the above checked.

Please report back and let us know how you get on!
