Engine over haul cost incl labour

[10 inch Terror]

My experience of those alloy kits is not good altho ive never used them myself :
Kit 1 had over 3 mm of piston showing above the lower part of the exhaust port and transfers that didnt match by a few mm
kit 2 leaked through the liner and had a loose inlet stud dispite being a "reworked" kit
this was supplied as a replacement for kit 1 went back for a full refund minus postage .... owner found a 150 barrel and had it bored to 175 self ported it and is happy
kit 3 wouldn't go over 55mph after running in even with a 30mm carb and pm 25 pipe or a 22mm and clubman again ports all over the place and over 2.5mm of squish again a reworked kit owner went back to a sx 150 standard barrell
22mm carb and scootopia clubman and was happy
both these were friends of mine and the kits came from 2 well known dealers in yorkshire
they came to me as a last resort , both kits had been well fitted exept for squish both owners didnt want the hassle or cost of porting or re profiling but I did get paid for stripping them etc , if like me you enjoy a challange within scope of what you have in front of you then go for it but they didnt want the hassle the time or money
its all about time v money and expectations both wish they had gone for a branded kit as the final bill wouldn't have been much diffent

I've been looking into these kits and after some research I have to agree with the above comments. They look like a whole heap of trouble.

It's easy to get sucked into a motorcycle mentality of making it go fast, faster, fastest.

A 175 engine, properly set up will run and run without costing the earth in new crank, ignition, clutch, brakes etc etc. Just set it up and enjoy the ride.

The overhaul cost me £360 in the end new front sprocket , gaskets , seals , bearings , must say runs much better as well
