Hi Just wondering if anyone has any ideas. Basically my bike has lost a lot of compression for no reason. I rode my bike and put it away in my garage two days later went out to start it and nothing it seemed like it was flooded so i drained the carb and tried starting it and it sounded like it was bogging so i tried bump starting it. nothing. next day went back out to it and it had lost a lot of its compression. i have tried turning the petrol of kicking through 40 times and no compression regained also tried with the decomp lever in.nothing. the decomp appears to be moving smoothly as i took the bolt out of the side of the cylinder and can see a small cylindrical connector turning. i have a spark, petrol is going through and air appears to be ok. any ideas at all anyone. id really appreciate if you could help. I cant understand this as before i put it away it had loads of compression and was riding really well. Cheers everyone.
