Just rode the bikes...
Based on jse comments, got the 2002 Pro chassis for the quicker steering and magnesium engine cases. The chassis was only made for 1-year and is a odd mix of parts.
Complete rebuild of engine top and bottom end. Installed S3 225cc kit
, S3 Stars cylinder head
with high-compression insert, and GasGas UK flywheel weight. Rebuilt waterpump, and upgraded clutch to 2006+ specs. Modified FMF Turbine Core 2 from my GasGas EC300 to replace stock silencer and add spark arrester. Replaced Comex radiator fan and Leonelli module. Removed lighting harness and installed kill switch
Revalved Sachs rear shock (2-stage compression and rebound) and changed spring rate. Installed shock upside-down. 4mm preload. Regreased rear linkage and swingarm pivot.
Installed Formula 'Factory' forks with GasGas anodized Ergal triple clamps. Installed ProTaper Hi bend SE handlebars with ProTaper Medium compound grips.
Completed restoration of 1995 JT35. Put a full set of NOS body work and '2-lens' headlight in storage. Replaced the Pirelli Gara Trials with Dunlop D803. Installed Renthal handlebars with Renthal Trials grips. Replaced fork fluids, and coolant. Running Maxima 75W transmission oil.
This JT35 may have an interesting history if built by Jon Stoodley AKA jse for Steve Darrow for the World Championship. Has cylinder head mods, and Keihin PWK carburetor.
