I have a 2001 blaster that I'm having a issue reving past half throttle..u can rev it in neutral but in gear u go past half throttle it bogs and cuts up..seen some posts talking about tors and parking brake? Could this be my issue? New reeds and plug
 
The parking brake will not allow any throttle above idle.

Is the carb spewing fuel?

The plug could be breaking down under pressure.
 
type of plug?
compression reading?
what is airscrew set at?
air box lid on or off...clean air filter....stock carb...any mods??
sounds like a carb problem though,,open up the carb clean it/and the float needle as well

New ngk plug...open air box no filter (temp) not sure on air screw..it was running good till here recently..fires on first kick revs fast and strong just won't wot in gear
 
I'll give you some advice, don't run it again til you get a filter on it!! If you've ran it without it for any length of time you and your not jetted properly, than you may as well rebuild it. I'd be checking compression before doing anything else
 
if your not going to take topend off to inspect...then at least compression test it....you can buy a comp gauge for 30 bucks at a autoparts store.
airscrew should be around 1 1/2 turn out from fully seated.turn it all the way in to the right then back it out 1 1/2 turns=540 degrees.it is the flat head screw right beside the fuel line on stock carb/idle is under the seat on top if its stock.
get a filter.....that 15 dollar filter is going to end up costing you and whole motor when it breaks piston/then you have to split cases to get it outo_O
ngk b8es is the correct plug or br8es.
if oil injection is not hooked up then it is 32:1 mix =4 oz of two stroke oil per 1 gallon of gas.

final judgement....it is your carb or low compression....from what your telling us:)
 
Well today I noticed exhaust leaking from the Jean so I'm guessing my issue is headgasket
 
Exhaust leaks are a totally different kettle of fish to a head gasket leak.

Remove the head, lap the head, fit a new gasket.

3 heat cycles and re tighten the nuts on the head and cylinder.
