                                      Cheers guys! Its been a long time coming, most of the time it took me to rebuild it was waiting for parts from MSP but least i know the engine is 100% good to go, just need to get the rest of the bike going now.

                                          Hiya again folks

                                          So i have some good news i have started at a garage as a welder / fabricator repairing rotten sills on vans, cars, buses etc....

                                          My boss is kind enough to let me redo and weld new nuts and other work to all my parts before he sends it all off for powder coating, i have one question regarding the suspention linkage and bushes etc... I dont want to pay Β£355 for genuine yamah bearings and oil seals etc... so i want to know what size bearings i can get as a replacment instead of the standard roller bearings i wanna use ball bearings instead anyone know what size bearings i will need?

                                          D 1 Reply Last reply
