adam1 Posted May 19, 2011 Report Share Posted May 19, 2011 Hi all I have a current thread running about coolant/oil levels but now need some advice about my smoking Beta! I realise this has been talked about previously, but mine seems to run well,maybe slightly fluffy at really low revs, but well all the same. It hasnt always been like this and the smoking only seems to occur when i am traveling up hill in say 3rd/4th gear or long steep hill climbs. All my mates bikes doing the same hill climbs/hills etc dont seem to smoke at all. Please Advise any help really appreciated again Cheers Adam Quote Link to comment Share on other sites More sharing options...
nzralphy Posted May 19, 2011 Report Share Posted May 19, 2011 Your 'fluffy' running bike is probably because it is running rich and you likely have old/excess oil in the pipe. Go find a HUGE hill and really work the bike. Smoke will spew out of the pipe but that is good. Do this a few times unitl it stops. Or remove the whole exhaust system. Remove the muffler packing. Flush inside the tubes with petrol a few times. Let the excess fuel evaporate over night (important!). Put in new packing. Re assemble. CLean and properly oil the air filter. Check it doesn't 'fluff' while riding now. If it does post up here again. Quote Link to comment Share on other sites More sharing options...

dan williams Posted May 19, 2011 Report Share Posted May 19, 2011 (edited) Also have to ask what oil ratio you're running. It not only affects the here and now but how much residual oil collects in the bottom of the crank that suddenly shows up on those long hard high rev climbs. My bike also smokes a bit after a long climb but most do. Edited May 19, 2011 by Dan Williams Quote Link to comment Share on other sites More sharing options...

Hi Dan, thanks for the reply, i use either PJ1 silver fire or now i am going to start using putoline TT trials pro pre-mix and as long as i have had the bike for have ran about 70-75ml of oil to 5ltrs of unleaded fuel. I have got the exhaust off at the min just soaking it in Jizer then going to clean it in water and re-pack the exhaust. I also have cleaned and re-oiled the airfilter.

adam1 Posted May 24, 2011 Author Report Share Posted May 24, 2011 (edited) ...and? Don't leave us hanging. sorry dan, I went to tong on sat, it smoked like a demon at first poss excess Jizer?, but then settled down, still a little smoke at full revs in 3rd for example, but could only test this on the flat on the fire roads as there were no steep long hill climbs i could find. Going to the same place i noticed it originally tomorrow fingers crossed so will get a friend to film it then i can see if there is any difference. Also going to check the coolant level as i topped it up before i went, it spat some out of the vent pipe(finding its level?)but if its not at the bottom of the neck or just below should i be worried? cheers Adam p.s does anyone no what the mixture screw should be set at as now and again it doesnt rev out clean sounds a little fluffy/wooly if you no what i mean.
