Glorian Posted February 20, 2015 Share Posted February 20, 2015 Right. So after spending a shite load of money to have all the engine torn apart and checked after a ride home in the rain (light) yesterday the engine started to splutter and struggle after about 10 minutes. Managed to get home and it was on/off doing this still.. So to me it sounds more like an electrical issue no? So as i had ONE ignition coil changed. i might change the other to make sure it's not that buggering about.Other than that any suggestions?

Joeman Posted February 20, 2015 Share Posted February 20, 2015 does it feel like someone is hitting the kill switch momentarily?if so, its probably electrical. Quote Link to comment Share on other sites More sharing options...
Glorian Posted February 20, 2015 Author Share Posted February 20, 2015 It's more..Say im going down A12 at 70 (yeah right) 6th gear at about 6000RPM. Then i hold the throttle and power will feel like it's disappearing, revs drop down 2-3000RPM and a second or so later they jump back to where they were..Also when going around at slower speeds in second gear i open the throttle to accelerate up a hill and it chugs as if it's not getting all its power out.

Chrissb6 Posted February 20, 2015 Share Posted February 20, 2015 Sounds like a fuelling issue to me mate, check the fuel filter if it has one? Then the hoses and air vent on the fuel tank , then check the carb floats jets etc.Hope your soon sorted Quote Link to comment Share on other sites More sharing options...
Glorian Posted February 20, 2015 Author Share Posted February 20, 2015 Carb floats were broken (2 of them) so he replaced all 4 while he had it all open. Will check fuel filter but it has done almost 200 miles without issue last 2 weeks, just seems in the rain it's gone kaput. Quote Link to comment Share on other sites More sharing options...
Timmy Tiger Posted February 20, 2015 Share Posted February 20, 2015 This may help or it may not but I had a bike do a similar thing once. Couldn't work out what it was. Some days it was worse than others. Always seemed to tick over fine and on a little bit of throttle say below 30 it didn't seem to bad. Anyway because I couldn't get it sorted I sold it to a shop. They had it standing for a while and when it did eventually get sold on the test ride it broke down. Turns out it was the fuel pump on its way out, and when it actually broke for good it made it easy to spot. Quote Link to comment Share on other sites More sharing options...

Only thing is why would it stop in the rain? Gonna try it tonight see how it runs. Quote Link to comment Share on other sites More sharing options...
eastanglianbiker Posted February 20, 2015 Share Posted February 20, 2015 get a can of silicone spray and spray all plugs and connections with it to seal them up see if that helps Quote Link to comment Share on other sites More sharing options...
Adam Posted February 20, 2015 Share Posted February 20, 2015 Could it be the fuel tank breather is partially blocked and when it rains it blocks it completely creating a vacuum in the tank? Quote Link to comment Share on other sites More sharing options...
