I think this is the holding tool

Diagram of front forks

Chris put the head steady on the barrel studd ,then fit the nut and bolt loosely ,then prise the back bit to the frame mount ,and fit the bolt ,it can be a pain but shouldn't really be that far out..... keith

I would pull the engine apart and check the box , going off your first post ,i doubt the missing thrust washer would give these symptoms ....Good luck

Hi there I've just done mains and seals on a ty 80 engine .... 6204 /C3 main bearings (go for a good brand ) Mag side crank seal 20x35x7 Clutch side crank seal 28x40x8 Front engine sprocket 25x40x5 Gear selector shaft 12x22x5 Sealant for centre cases You might need a puller (or make one) to split the engine cases Have fun

Just found a photo of a so called 1986 Sherpa 199B on this web site http://www.custgp.com/downloads.html , very very nice but too late by 1986

Nice bike ,where did you get the footrests from ????????

I had the same problem when i bought my sprite trials bike , the closest match i found was the Marcelle , but the marcelle as 8 horizontal fin's on the barrel , but mine only as 7 .......

Looks like a marcelle from the bottom identification ........
