Ok so here's the thing, I just got this Blaster and it was running ruff, ruff meaning boat loads of smoke/oil (oil meaning crankcase oil) out the exhaust and an extreme lack of power, bogs down real bad. When I replaced the piston there was tons of motor oil on the piston. My gas ratio I use is 32:1
Also when it does start up it backfires out the exhaust.


What I've done:
Replaced crank seals
Replaced clutch cover gasket
New top end (cylinder, piston,rings)
Top end is factory replacement 66mm piston
All new top end gasket set
Completely disassembled and clean carb

The oil injection has been removed. (Before I got it)
TORS has been removed. (Before me as well)

Any help would be GREATLY Apprieciated

Thanks in advance
