My GK76A wont start, it has fuel + spark.

when i crank it over it back fires, it just wont run.

Any ideas?

Sounds like the good old carb flooding problem again.
Have the o rings been done?

They were done over 6 months ago but the bike has been sat for 2 months. Ill whip the carbs off for a clean and ill inspect the O rings.

Is it the first time youve tried to start after winter? Before you pull the carbs it may be worth putting the battry on charge, cleaning the plugs and then trying it with the petrol tap on prime. I had my bike stand over winter and it complained a little due to the carb bowls being dry but you should'nt need to strip the carb if you rebuilt last year.

I fully charged the battery, it flattened it. So i put one in off my road bike, it flattened it. plugs were cleaned when i used the second battery, i used the prime setting also....

Cured!!!!


Faulty fuel tap flooding cylinders 3 + 4. plugs cleaned, fresh battery and it fired up into life.......


I forgot to mention that im doing silverstone on it at the weekend, im so glad i got it running.....

Nice one Morris, i'd have been gob smacked if it had been the o'rings after relpacing them as they will be good for another 5 years after being renewed. Hope the weekend goes to plan.
