jim12 Posted January 1, 2019 Report Share Posted January 1, 2019 Hi everyone new to the trialling game,did the 250 have pinking problems as well? Quote Link to comment Share on other sites More sharing options...
peterh Posted January 2, 2019 Report Share Posted January 2, 2019 My experience was no, for both the 2014 and 2015 Jotagas 250. Admittedly i have fitted Boyesen reeds in both bikes and for the 2015 model changed to an OKO 26mm carb as documented in the pages of this forum.

huski Posted January 2, 2019 Report Share Posted January 2, 2019 Mine never did,carb settings were standard.Are you running it on super unleaded? Quote Link to comment Share on other sites More sharing options...
jim12 Posted January 2, 2019 Author Report Share Posted January 2, 2019 I have just recently bought mine and when it's hot it's popping cracking from the engine and when you twist throttle it's not picking up,could it be the cdi?.Runs great for about an hour then starts when its hotter.

huski Posted January 2, 2019 Report Share Posted January 2, 2019 Is the fan switching on ? Seems odd it'll run for an hour before it mucks about.Is the fuel tank breather blocked? Quote Link to comment Share on other sites More sharing options...
jim12 Posted January 2, 2019 Author Report Share Posted January 2, 2019 Tried it again tonight and it's popping straight away,yer the fan has been kicking in.Had 3 outings on it and one of the days it was fine,that's what's making think cdi!.Gonna clean the carb check the reeds and change the spark plug,it seemed worst the last time would not rev up like it was running out of fuel,and pinking Quote Link to comment Share on other sites More sharing options...

riffraffretro Posted January 7, 2019 Report Share Posted January 7, 2019 Running issues likely to be carb or electrical; pinking probably down to Octane rating of fuel... try a branded Super, such as BP Ultimate. Quote Link to comment Share on other sites More sharing options...
