  1. gotcha, nice one guys. i knew it had to be something like that. i will premix it for now till i sort the shimming. wemoto have the shims in stock, i will get a digital gauge on the shim's that are on there now and report back. Thanks!
  2. hi guys my stepdad's bike has been quite rich since hes had it. it has had a FULL rebuild including all gearbox bearings etc but still has this lingering issue that we cant work out. it drinks a litre of 2 stroke pretty easy (under 400 miles). My bike of the same year and setup last's around 700+ miles. He's getting alot of black oil coming out the exhaust, runs very rich through the rev range. Stock jetting, float height has been set as per manual and it has a 3MB head with 3 wire powervalve, stock front pipe with a DEP rear. the pump operates correctly via the cables and also bob's up and down. the little marks on the pulley line up nice. i dont get it, because these pumps cant really be "adjusted"? typical really because he wants to sell it soon as he's doing his DAS but obviously cant sell it like this.

    hi guys, im new to the forum and wondered if i could get some help im rebuilding a DT 125 engine (il show project pics later) im replacing all the bearings with new ones, most the new ones are fitted but today i bought the last 2 i needed witch have been hard to find. the bike shop i got them from told me i could remove the seals from the bearings and run them open in my gearbox. now all this is fine but what concerns me is the fact the inner cage that holds the bearings in is a type of plastic. will this be ok to use still? im worried they might wear with grit or contaminents in the oil. the bearings are for the counter balance weight shaft and the primary gear shaft (clutch basket side). the old ones i removed are actualy in good condition, its just i wanted to use the new ones i got today if i could. Thanks
