GZ250 power increase.

Hey Quime rider

I did a test yesterday evening. The temp was about 20 c ( 70 ) degrees and almost no wind. I got out on an open stretch of highway
no hills . The bike was running well. I could easily hit 120 k/ph so I got upto 100 k/h then pulled the choke lever about 1/8 forward. I
opened the throttle and pulled easily to 120 k/h then open the rest of the throttle I looked over at the tach it read 8000 rpm ( 5 th gear ) and the speedo was touching 130 k/hr (81 mph ) it was still pulling but I had run out of space so I let off .

Very rare to get ideal conditions but 80 mph is acheivable. ( still have stock 120 main jet ).

I read that the choke pulls a plunger that opens an ericher jet and air jet to feed the engine. I spoke to qa mechanic who did and engine rebuild for me in the past about this phenomenon. He said that the mix had been enrichened enough to allow the engine to reach
its power potential.

Now that it is done I will slow back and drive to enjoy the ride. I just had to see the bike reach it's potential.

BTW I get 85 mpg regularly .
