Flooky Posted October 20, 2019 Report Share Posted October 20, 2019 Hi, my son just bought the above bike, we went to practice today and it was fine , when he went to get over something bigger it bogged, badly..I had a go and when I wound the throttle wide it bogged like the brakes were on. We went back to the van for a head scratch and fitted the quick action from my sherco ( white tube, one that came off was black ). fixed !!! now I am glad it is but I cant for the life of me see why. We tried everything to make it bog again and it wouldn't.. any ideas ? cheers Quote Link to comment Share on other sites More sharing options...
totty79 Posted October 20, 2019 Report Share Posted October 20, 2019 My guess would be that a bit of dirt was blocking the main jet and it no longer is. Can't see the throttle being relevant. 3 Quote Link to comment Share on other sites More sharing options...
Flooky Posted October 20, 2019 Author Report Share Posted October 20, 2019 I know, I thought that, but it was as clear cut as slow throttle...bog...quick no bog. I gonna swop back to see...the bikes haunted !! Quote Link to comment Share on other sites More sharing options...

Regardless if you are encountering a carb problem best to strip carb and clean just to be sure. Kehein? if possible ride with a fast tube.

Yeah , we were rushing a bit , I will look into carb/jets etc. Having just got the bike we wanted to see how it went etc. We bought it from a friend so I will ask if he had any issues. cheers all.

huski Posted October 21, 2019 Report Share Posted October 21, 2019 Great carb,more susceptible to dirt or incorrect tuning than a dellorto but better when right,much more precise and smooth.Need to keep the air filter clean too 1 Quote Link to comment Share on other sites More sharing options...
nigel dabster Posted October 23, 2019 Report Share Posted October 23, 2019 Kehein needs an inline fuel filter. 3.0 slide works best. Quote Link to comment Share on other sites More sharing options...
