March 2000: Check
the weekly update section for future news of the
2000: Now almost £500 poorer but have everything back from
Taffspeed inc. new bearings, seals, gaskets, oil etc. Top end & new
crank look sexy (if you like that sort of thing!) All I need now is a
spare 5-6 hours to completely rebuild the top end & refit
2000: Awaiting return of everything from Taffspeed. Cylinder head
& barrel are being dowelled so the head is always centred. This also
means that no gaskets are required during re-assembly. Barrel has also
been ported (exhaust port 8% wider & 4-5mm wider/rounder) & re-nicasiled.
Also got a new 110mm crank as the old one had a 22.9mm big end pin which
doesn't take the 22mm Jap crank without a whole bunch of machining. New
70mm piston, small end bearing, gudgeon pin, drive & magneto
side bearings, seals, clutch plates, pack plate for barrel (longer
2000: The GP is now finally back on British soil. I've found the
TS1 barrel and after talking to Terry at Taffspeed I need the following
to at least get it on the road. Also need new clutch plates & check
how badly casing is damaged where the big end blew in the crankcase.
barrel with Nicasil is £95
Fast road porting (+2-3bhp) £50
so new one with Japanese conrod fitted to webs £145
compression head £38.50
September 2000: The TS1 seemed to seize solid riding to Vancouver BC
from Portland OR (50 miles into a 300 mile trip). After getting the
scooter home and dismantling it I've found the big end bearing has
disintegrated, totally fucking up the piston and head. The barrel has a
couple of scores on it, nothing too severe so I'm going to get Taffspeed
to give it a fast road tune and replate with nicasil. Also I'm going with
a longer Yamaha conrod, new TS1 piston & new cylinder head.
I'm shipping all my scooters back to the UK as we are emigrating so will
update this page with pictures of the damage and rebuild progress.
