Hi,
Thank you for reply. Well, I took the bike to the forest lately And when it is running, it "wants to go up on wheelie" on the 3rd gear. However, if for any reason engine shuts down, it is very difficult to start it again - it doesnt not start, later it fires, and if I open full throttle during starting process, it seems like starter stops its work (to be short: opening full throttle kills starting). If I wait for a ~ minute, in mostly cases I can start the engine. Maybe it is normal for GG? I remember having Yamaha XT660R - I could start it again after engine shutting down immediately during riding, even when I am still on the bike |

Yeah, the hard starting sounds familiar
If you try to start, are you touching the throttle? If yes then DON'T! There's two ways to start GG: 1) ignition ON, wait until the fuelpump primes and then hit the start button. 2) If after 2-3 tries no luck then: ignition on, fuel pump primes and then turn the throttle fully open and then hit the start button. Moving the throttle during starting is NO-NO Is your starter okay? I had also some problem when starter clutch was slipping.... But yeah, injector and TPS could be also issue |

Thank you!
So, throttle should be opened beforing pushing starting button, if the bike failed to start in 2-3 times? |

Yep, hold full throttle and then push the start button. Worked for me

Thank you again!!!
BTW, yesterday I've done compression test, and the reading was 0.5 Mpa (~ 72.5 psi or 5 bar). Do you know, whether is OK? I cannot find info about it..... And I've found the info (in workshop manual): The correct compression of a cylinder indicates that the internal conditions are good. The decision to inspect a cylinder is based on the results that we obtain when measuring the cylinder compression. Compression verification should be included in concessionaire inspections. DATA Compression: Standard: 1000 Kpa (10.0 Kgf/cm2). So the journey to find out the problem (valve clearance, pisto, rings, etc.) begins.... Last edited by expirmininkas; 01-19-2018 at 01:22 AM. |

Did you measure the compression correctly? I mean cranked the engine until the pressure didn't rise anymore? Usually it helps to hold throttle fully open.
5bar is too low. |

Yes, I did measurement with throttle fully open. And there may be two things:
1. My measurement instrumet is too old/faulty, or 2. Compression is too low, which is very possible, as I have problems with starting. I've found somebody that repais GG in Lithuania, so, I'll take the bike to them to do the valve clearance checking. |

If you need any parts then contact with Antonio at Motocrosscenter. If i remember correctly then you can get piston from W?ssner but other parts are hard to find. I got good deal from Antonio...original piston/cylinder etc.
Let's hope you need only piston change |
