Rear wheel drive chain question.

<< < (3/3)

Lobo:
I’ve often wondered about the accuracy of the markings, and whilst matching exposed threads method myself, realise this isn’t the answer as it assumes perfect symmetrical build of the two ‘forks’.
I’ve occasionally done the task with a laser beam (modern string)…. but really have to ask, “is it that bloody important?”  Seriously, (& I don’t know the answer), for the performance of the bike, tyres etc, are the Swing Arm graduations + eyeball not accurate enough?

Back in the 1960's I just went by the markings on all my bikes - the naivety of youth or the overthinking of old age!

Bryanj:
When in a dealership i was told by Honda to NOT use the marks to be same as they could not guarantee accuracy but to line the wheels with a straight edge fist and from then you could move each side the same number of marks to keep alignment good.
In fact over 90% of the time we found that after using the straight edge the marks were exactly the same side to side

Hi Roo

Yes it’s getting there very slowly

Trouble is it’s not even a hybrid with a factory frame / bike with a change of certain parts

Completely a one off that make is a very hard build as the base is a Tigcraft super mono race frame with other parts sourced from other manufacturers such as a Yamaha 350LC motor, KTM wheels a Honda NSR 250 rear arm fitted with Ohlin mono shock and Cagiva Mito front forks etc etc

Under a dust sheet at the mo but it’s next on my list of things to finish

Take care and best wishes Al
