Yamaha XS Coils for Honda 305 scrambler

PapaWoody · Post by **PapaWoody** » Thu Sep 08, 2011 11:40 am

about a year and a half ago I pulled a 71 cb350 from behind a barn. I had to completely rebuild the motor and most of it's components got replaced. For coils I used a set of new yamaha xs coils with great success. I have an extra set and was wondering if they would work on this 305. Just wondering if anyone had a nay say with a reason off the top of their head. Thanks

Well I am building this cl 77 with no coils and I have this brand new set of coils from an xs sitting here with no bike. It worked with my Honda 350 so I thought maybe i would be in luck in which case I figured someone here would know

I asked cause the forum has lots of discussion headers which this info would be better suited for and ya never mentioned CL77 so ya caused me to wonder. ........lm

Welcome to the forum!!

You mentioned 305 Scrambler in your subject. That means CL77 to most of us here.... :-)

Measure the primary resistance of your coils and if they are around 4-5 Ohms, they should be OK. If they worked on a CB350 that should be a good clue as well. Just have a go, see what happens and report back. We'll all learn something that way.

Typically if they are coils from a points ignition XS650 they should work fine. Coils have different resistance for points and or electronic iggys. I used an RD350 Yamaha coil on my Bridgestone 100 and it worked fine (and this was a 6V system)!
