Many thanks for that information DD I noticed the earlier timer has a fixed amount
of movement where the later one doesn't seem to have a limit on the advance
unless I'm missing something?.
Thought I would just list the spec of the bike I'm in the process of building.
As mentioned before WL lower end and K cyls. and heads
stock flywheels offset bored for sportster pin and rods ,rebalanced
+050 pistons with bevel edge added
heads modified to KR profile and checked for volume
one piece stainless KR pattern valves
double mini valve springs , KR spring covers
45 parts depot tappet guides, lightened sportster tappets
full set of khk cams , needle roller bearings in cam cover
oil feed to front cylinder from return line ,inline cartridge filter
oil system fairly stock at the moment
Triumph pre-unit gearbox , duplex primary drive, stock ratio's
housed in Norton wideline frame ,new forks - external springs
1969 2ls front brake, T140 rear disc for better ratio options
That's it for now , still need to make some exhausts, not sure whether
two singles or two into one , and also to make a seat.
Hope this is of interest wryders
