Bike over heating after 40 mile ride

Can anyone recommend a new set of coils for my 400 4 that are decent , original coils are ok but leads are moulded in so cannot be changed so ideally I would like some coils that I can change the leads on when they get ropy.

I fitted Dyna S coils as part of their electronic ignition kits, I adapted the existing coil brackets to make the Dyna coils fit.

We've all been there Ken, but if it's any consolation, I've just dug out my original owners handbook, and it advises for the first 600 miles, do not exceed 8000RPM, and that's with everything being brand new. Enjoy it!!!
Ken4004:
Thanks For the info I’ll open her up a bit more, I must say I am very impressed with the handling around the bends it really inspires confidence.

This is an interesting looking bit of kit - not cheap, with Boyer-Bransden name.

I noticed yesterday that no 2 exhaust pipe warmed up a little slower than the test although it seemed to start OK so I believe the cable / plug on no 2 is occasionally breaking down.
The leads on all plugs are a bit short like they have been shorted a number of times so time for new hardware .
