rcampobasso@gmail.com Posted October 14, 2017 Report Share Posted October 14, 2017 Hi, I'm need of a little help. I have a 1994 gas gas 327cc . The bike starts and then bogs out and dies after about 15 seconds? I noticed it will cold start then warm up a little then die out. It won't start when warmed up. Can anyone help me troubleshoot this bike please? Any info on this bike would be great I just got it and no nothing about it. I am brand New to trials.

lowbrow Posted October 14, 2017 Report Share Posted October 14, 2017 Hi, welcome to trials and the joys of bike maintenance! From what you describe I’d suspect an air leak on the inlet side of the motor and if it was mine I’d do the following to eliminate all probable causes: Check flow of fuel from the petcock is good and the tank breather hose is not blocked. If no better then proceed to: remove the air box, clean and oil the filter if dirty; remove, dismantle and thoroughly clean the carburettor making sure none of the jets or airways is blocked and the float level is correct; remove inlet and reed cage, and any spacer between the reed cage and crankcases. Check reeds are intact and that there are no splits in the inlet rubber. Check carburettor is a snug fit in the inlet rubber. Some 327s had the larger 28mm Dellorto so has someone swapped to a 26mm without changing the inlet? (We used to use the 28mm inlet when installing a Keihin, back in the day.) If everything is okay reinstall the reed cage/inlet using new gaskets and a light smear of silicone gasket goo on every surface. Fit carb and air box and you should be good. What better way to spend a Saturday? Good luck! Quote Link to comment Share on other sites More sharing options...
