ZXR400 L3 Rebuild (Bristol)
Posted: Tue Jul 14, 2009 12:18 am
Bought it for £450, got a load of t&t and service history but a non runner due to undiagnosed motor problems so stripped motor and found this:

Luckily the valve didn't drop right in and act as a centre punch for the bore so just a rehone and machining to remove head damage was in order. Also decided whilst I was at it I want to give the top end completely fresh components with new pistons/rings/collets/stem seals etc all around. Here's what's its going to cost in parts:
Done countless 2t's motor builds but this is my first 4t build, looking forward to the piston's arriving from Japan and getting on with it. Once done I doubt it would've worked out much cheaper than buying a running zxr400 l3 but I'm happy to use this bike as opportunity to learn about 4t's. Also I'll be happy in the knowledge that the motor will be good for a long while, ready for my jaunt to isle of wight for august bank holiday
.
Just wondered as this L3 is an import will it be restricted just via the speedometer? Or by any other means?
Ta,
Jack
P.S. Any other Bristolian/Surrounding area members?
