need to know how many gears does a 1978 Sherpa T 175 have, and what is the best set up for sprockets??

also is electronic ignition  as good as its made out to be? is the cost worth it?

and best way to set the timing on the points stator set up.

thanks in anticipation!!

Surprising what can be done when you have the time!!

the wing was one of my goldwing restorations from ground up!!

sadly to heavy for me now,so I thought something lighter was called  for

5 gears.

Electronic ignition very good if bought from right supplier/ manufacturer. Expensive when you can buy an old lawn mower and rob the ignition off it. Skill level high (many spanner’s rating). Or equate cost of electric ign as against numerous contact and condesor sets that will take ages to wear out and give good acceptable running.

Piston travelling up toward tdc ( top dead centre) at 2.3mm before tdc contacts should just be opening, breaking coil feed circuit and causing rapid collapse of magnetic field in coil windings and hence high-tension (HT) spark at plug gap. Make sure you rotate engine in normal d.o.r. Now ste timing to next experts view on best timing setting???

Thanks for the comprehensive answer!!

i had found that it was a 5 speed,I rang Bultaco uk,they are very helpful.

i will try the new points and condenser route before I spend £200 on electronic. 

I'm not in a rush and have plenty of time to play with it.

apparently this has not been run for 2 years,although last owner had fitted a new mikuni carb it was all gummed up,that has been well cleaned out so can only be the timing at fault.

thanks again!!
