Welded clutches-who can tell me

[simmo]

will it spitt me off like sparmanglenn ?

Any back wheel will lock anyway even with the stock BTL it just helps
All my roads trips are with the welded BTL when around Aust, Tassie etc
If your thinking for a serious clutch grab you should be looking for a lock up or slipper set up
If you weld up your BTL all you do is take a bit more care backing off in the tight stuff
Other people fall off also in the tight stuff with a stock BTL
