Water Cooled Suzuki 220 MRB
Posted: Sat Jun 06, 2009 10:28 pm
This little beuty rolled into the workshops today, chap from Scotland brought it down for Sean to have a look at. I'm not sure of all the details, but the basics are that its a rather trick water cooled mallossi 210/suzuki 220 conversion. Lovely scoot, lots of nice touches, rear disc brake, Lammy forks, RGV mudguard, rear lights intergrated into indicator lenses.....very nice.
Built by MB 9 years ago, a cracking piece of engineering from Mark Broadhurst, and 9 years later, still a great piece of kit that lots of Vespa owners drool at!
Its obviously been fiddled with since its original build, as we noted on stripping the top end that the base gasket hasnt been cut properly and actually blanks off one of the transfers.
Anyway, recently the owner arrived home from a rally, realised that a hose had come adrift and that the engine was cooked.....resulting in a non-runner. Sean has been tasked with the job of stripping the beast, assesing the damage and repairing and rebuilding.........check out the pics below.........
Scoot on arrival:
Nice Lammy forks and RGV mudguard:
Trick rear brake:
Awesome work, and light flywheel....although the stator plate behined it was rattling loose!
Signed and dated by Mark:
Cylinder head cover removed:
Cylinder head removed.....but soaking wet, studs were less than finger tight, we reckon the loose hose cooked the cylinder and head, and blew water through the seals into the cylinder:
Cool cylinder porting in this sleeve, but bore is now drenched since customer cooked it:
Another view:
Standard Mallossi 210 for comparison:
Another view, MB vs Standard:
MB exhaust port:
Standard 210:
Someone fitted a new gasket....but it blanks of some of the transfers?
Sadly, all this power has been eating up the engine casings.....cracks are appearing, so its not looking good:
So there you go, 9 years later and classic engineering still something to drool over......a hose gone adrift has cooked the head, a loose stator may have fooked the timing, and the power is stressing the casings. A bit of TLC from Mr Brady will see this 220 monster back on the streets soon........tearing up the tarmac and snorting as it once did.
