I'm looking for a spare Yamaha XV750 tci/cdi unit to test a theory on...
:2guns: I just read an interesting article on the virago owners web site about the aging characteristics of the Yamaha (and probably every other) cdi unit capacitors. It argues very convincingly that the original capacitors were only rated for 15 years and after that will deteriorate with a resulting reduction in power and performance. Both my XV750's are pushing 25 so it stands to reason that they will be perfoming below par and could benefit from a boost of new caps in the ol' tickeroo (and we all know how that feels).
So this week's plea for XV750 parts is for a spare XV750 cdi unit that I can rebuild with the new components without risking the two I have that do actually work if not perfectly. The article also points out the Yamaha wouldn't have used the best components available in order to keep the cost down in the production run, so replacing with modern high quality capacitors will improve the performance of your bike even if it was still running OK to begin with.
This undoubtedly applies to all bikes with cdi or tci ignition which is all of them from the early eighties onward.
