not much going on the tv tonight and i thought id start the 23cc oddie's rebuild bearings are perfect with no play or signs of wear so ive given them a good flush out with petrol and reoiled them with 2 stroke oil,,,
seals fitted and bottom ends sorted i made sure to oil the seals before refitting the crank and due to the bottom end being oddified and ported the copper gasket never fitted right and over laped the porting so dr dremel sorted that out now its perfect with no over lap of ians great porting,,
im suprised how much work goes into his modded engines it not just a head kit but a complete full mod engine which is why he can get 6hp out of a 23cc ive changed the piston pin and needle bearing for new ones and again oiled all parts,,
also fitted a new 0.7mm ring and red locktighted the 4 head bolts i didnt do the 4 lower case bearing yet as ive got to remove these to refit the red race kit,,turning the engine over by hand its now nice and tight with full compresion again im not going to bother with the zero drag seal this time as i think there a waste of time and once they wear the engine sucks in air and leaks oil which i think was the main problem i had,,
once this is refitted to the bmw after ive treid the stock zen im going to play about with the stock engine im going to try a few things like knife edging the conrod and polishing the inner casings and exhaust port,,it may even get sent to ian oddie for him to play with and means it wont need to be race legal he can go all out on the thing
