1999 YZ125. 38mm Smartcarb. 30:1 with Redline Racing oil. Plug is an NGK BR9ES (stock heat-range) that's been side-gapped (it was running too rich for so long I've got a good collection of BR9xxx plugs. Idle hands and all...). I got the bike in terrible shape for cheap (but paid more than I should have) a couple of years ago. I've been slowly fixing its issues one by one. The biggest issues were a cracked tank and a carb that was buggered in several different ways including running pig-rich and actually had one of the screws holding the top on replaced by a wood screw. I decided to splurge on a Smartcarb and after chasing my tail for a long time turning the adjuster the wrong way to lean it out (RTFM) I've got it to this point. Two-stroke gurus, is this good? Would a click or two leaner be playing with fire or be just right?
2002 YZ125 - Trying to get some riding in before the season is over - Sorry for the novel but wanted to include all the details I could that might help diagnose/figure this out: CURRENT SYMPTOMS: After the bike has been sitting for a while I can kick it over with a few kicks. I do this using the choke and the RPMS start fairly high and climb like expected. Before leveling out or stabilizing the engine starts to bog and dies. This happens if I hold no throttle, cracked, or wot. After this happens I can sometimes get it to start a second time with the same result. The plug is removed wet with fuel at this point. After this it refuses to start at all to the kick starter - even with new dry plug. Rolling it down a hill gets it to start again for a moment but then it immediately bogs and dies after a moment. After the last time rolling it down the hill and having it die at wot - the plug was removed dry. Bike has spark visually and to the... touch 😒🤣 HISTORY: A few months ago the bike had stock reed cage and reeds with mikuni carb that was dialed in for WOT motocross riding. I have been converting the bike into a trail bike since then. It would run on the trails ok but didnt like not having a place to rev out and would foul a plug occasionally. I replaced the reed cage with a vforce3 assembly. After doing that the bike seemed to run fine and rev a little faster. However occasionally when riding the engine would bog and die as if a plug was fouled - the plug would be taken out wet, bike kicked over to dry out cylinder, new plug put in, and usually start to run for a while - very intermittent. I installed a SmartCarb2 on the bike (brand new and setup for my bike) and it started on the second kick. I tooled around the neighborhood for 20 minutes after it warmed up and it seemed awesome! Super linear and no signs of bogging down at any rpm. I noticed after that check ride that there was a small puddle of fuel underneath the reed assembly - leading me to suspect an intake leak was causing my previous ghosts. I took the reed assembly out and used gasket maker to seal all mating surfaces then reinstalled and let cure 24 hours. Now I am getting the current symptoms and cant keep the bike running longer than a few seconds. (there is no wetness on the bottom of the reed cage LOL) /////////////////// What can I test or check to help get this sorted? Thank you
Anyone tried a Smart Carb or a Lectron carb on the CRF150R? I am considering getting one of them and want to know your guys' opinions and which one you got/how big/what tuning you had to do? Let me know!
So my bike : 2001 cr 250 motor on an 02 frame with an Eric gorr 265 big bore kit. heres the story : I bought a lectron and could never get it dialed and had a continuous issue with clacking (detonation or pre ignition) after several and i mean SEVERAL attempts to get it right a d going through the bike I realized this isnt going to work. enter ~ technology elevated smart carb the carb has the main pros I'm looking for single circuit, choke on correct side, on bike adjustability to the rod to make changes as needed. I'm about to install the carb and am confident it's going to be night and day compared to how the bike was running with the lectron. I also made some youtube videos of my problems with the lectron... has anyone else had ... problems? More videos coming soon on the smartcarb and how it compares to the lectron .. cheers.
