Hi Guys,

Noob forum user, hope it is OK to post on here as a 1st post? Out of frustration and very tired arms I've come here to ask for some help if at all possible? :)

Purchased a Superbyke RSR (Sinnis Stealth/Quinqgi QM125-2D) for peanuts as a non runner, turns out a valve had come apart and was pounded a few times by the piston resulting in one borked head and holed piston.

I was all ready to buy a new head with rockers, new barrel and piston and then I seen a deal for a Keeway Strike 125 engine on ebay, 2015 model with 3k on the clock... starter motor is on same side as mines and its labelled as an 157FMI. Measurements of the case, bolt holes all match up but can I get it to fit... nope, top lines up but then cant get bottom/axle/main bolt to line up as its caught slightly on the front of the frame etc etc lol.

Is there any specific technique to getting these engines back in and lined up properly?

Many thanks in advance for any info/assistance.
