  1. So after much faffing through the winter months I succeeded in swapping out my old SR125 engine for the replacement. The lowest moment was when I was about to install the rebuilt engine into the frame when I noted that the previous owner had sheared off one of the exhaust bracket bolts inside the engine casing - I tried in vain to remove said bolt (including swallowing my pride and lugging the whole lot to my friendly bike garage) but it was just too tricky. I therefore removed the whole top end of the new engine and replaced the whole section with the exhaust port in. Cue lots of exciting moments when I screwed up the timing between the top and bottom ends of the engine. After much work (and fiddling) I succeeded in installing the reconditioned engine and low and behold, it fired up and worked straight away! I have rarely been as proud as I was that day. But..... An oil leak was spotted on the left hand side of the crank in the lower area - I think it is almost certainly where the gasket between the crank and the piston barrel would sit although I'm not 100% on this. Before you ask, yes I replaced all the gaskets and yes, I've torqued all the bolts up correctly - still the oil leak appears. Does anyone have any experience of this and can anyone suggest any solutions? I'm nervous of overtightening any of the bolts as I had a main engine bolt snap when rebuilding the engine (old I guess, hadn't hit correct torque) and definitely don't want to go through the same thing again....

    Hey Drew, Thanks for the advice - I've wired both up now (had to fit a new negative cable to the engine case, the old one was missing). All the lights work, neutral light on etc - however when I hit the starter switch - nothing. Not even a click. Bit worried that the new engine's starter motor is dud. Anything I need to check before removing it? Thanks

    Hi all, I've recently refitted an engine and since I connected the clutch cable back up I've had problems in getting the clutch lever to 'spring' back - there doesn't appear to be enough tension - I've tried tightening both the handlebar lever adjuster and the adjuster nearer the engine but with no joy - any suggestions?

    Hi all, I've recently rebuilt the top end of my sr125 engine and have refitted the whole thing back into the frame - now the tricky part, the electrics (wish I'd taken more photos first...) It looks like someone has done a bit of a hatchet job on the electrics at some stage as what I have differs from the Haynes manual - could someone confirm the routing of the cable that is connected to the starter motor? Where does it connect to and which route does the cable get attached to the frame? Also (and this may be part of the answer) what connects directly to the negative terminal on the battery? Any help much appreciated, I've got what looks like a snake's wedding on my hands and thought I'd ask instead of doing something really stoopid....

    Hi all, I've bought a replacement engine for my J reg SR 125 which I'm going to recondition and then swap over during the next couple of months - the replacement is one that has done about 10k. If anyone has any pointers or advice to give me at an early stage I'd appreciate it - at the moment I'm full of enthusiasm but don't want to do anything stupid in the first 5 minutes! The job therefore is: Recondition replacement engine, fit new gaskets etc. Remove old engine Fit replacement engine Any advice, however small is appreciated. Thanks!
