> the o/s stud nearest to the gearbox at the rear of the engine is broken off flush with the head, tell >me the engine doesn`t have to come out to drill it.....Please!!. You have 2 choices the first ..only for the brave... 1) Drill it out using a drill with right angled chuck (to clear the frame) but be careful not to catch the water jacket when drilling. Start with a small drill bit and work you way up.This method may invlove helicoils if things dont go to well...2) Head off and get it into a machine shop See Recoil for M7 recoil kits, about £25 for the tap, insert and 10 M7 coils. http://www.recoil.com.au/p_range_smlkit.asp Good luck Chris S
