Engine Swap 350 Kangaru to 250 frame.
Posted: 11 Jul 2017 15:14
As above I own a 250 2c which I think is a spanish import, and a non runner 350 Kangaru - age and model unknown which I want to combine into a 350 engined 2c. I plan to keep hold of the 250 engine for posterity... I realise that this has been done before - more or less but I thought I'd post for advice rather than searching the forum.
1) I assume the engine fits more or less straight into the frame, though I have heard it is necessary to trim one of the rocker covers?
2) I think, from memory that the 250 has a traditional european right hand gearchange and the Kangaru has a left hand conversion (?) I'm not right bothered which side shift I end up with TBH but assume I can use the 250 linkage on the 350 box?
3) I believe that some of the later engines have a Nicasil plated bore, is there any way of telling from the outside eg engine number?
4) While I'm at it I might as well convert to 12 volts and perhaps fit a less power hungry LED h/l bulb and Li ion battery, is there an easy way to do this? I believe some models of the Kangaru have a hybrid 12/6 volt system, and while I'm at it would I be better to use the complete 350 ignition system inc' coils etc or to purchase a NLM ignition system?
5) My 250 has a twin pipe exhaust system (sounds really nice with pretty much open aftermarket silencers ) which I would rather keep if at all possible, I assume I will have to have the front pipes cut and welded for this because of the extra cylinder height (?) any thought would be very welcome. I assume the bits that screw in the cylinder head are the same size etc?
6) I'm planning to use the 350 carbs, is it better to use the airbox and ducting from the 250 0r 350 or just add K&N type filters direct to the carbs?
7 My kangaru engine has a bit of casing smashed of on one side, the bit that covers the front sprocket, The engine still runs apparantly and certainly doesn't leek oil, can I just swap the side cover from the 250?
The 250 currently has slightly high and very wide non standard (? certainly look newer than the rest of it...) bars fitted, I believe the UK bikes were supplied with ace type bars which I would like, where these fitted to other Morini models? and rear sets would be nice if possible. (I realise this may be tricky with the exhaust system...)
9) any other advice or comment would be very much appreciated, thanks in advance.
