[gregr]

I was once told that the two piece crank on the 1983 BS1100E was welded much like the draG RACERS DO TO THEIR CRANKS. tODAY AT A DRAG STRIP SOME GUTS RACING gS MOTORED BIKES SAID THERE WERE NEVER ANUI FACTORY WELDED CRANKS. wHICJ IS TRUE?

The guys you were talking to obviously dont know their GS history very well.. The GS1100E cranks came welded at the press pins from 83 on... This included the 1150 motors as well. However, most REAL drag guys would have the cranks welded all the way if they were serious. Either the guys you were talking to dont know GSs, or arent real drag racers. The GS1100/1150 motors are classic powerplants and have been used forever on the strip partly because they're so durrable.

Greg, from late 82-2000 (That includes the late model Japan only Kats!), ALL of the 16 valve, press together cranks were welded from the factory! They were also MANY more than just 2 pieces in those cranks! Ray.

A local bike mechanic told me there was one pin on the factory welded cranks, that WAS NOT welded. He said the factory didn't weld the pin at the primary gear. Ray, can I trust this guy, or is he full of hot air???

My understanding is that the factory welded part way around on the crank pins where the rods are - a weld job after the crank was assembled. Not sure if all were covered or not. When a crank is welded for racing the amount of welding is more extensive but I don't know all the details; I've seen photos of where the main bearing pins are welded and the drive gear as well. Sorry I don't know more, have to wait for the experts.

Edit: found these photos from First timers thread...

Welding the crank is only necessary when using te motor for racing correct? It isnt needed in a commuter application where the bike wont see a strip or track just highway?

The factory started welding them for a reason...riders were twisting them...
And not just at the track...
