Hi all, sorry for long time to reply.
Bike is running much better now, had a few issues with the idle running away with itself. Turns out the slide isn’t returning by a fraction which is causing the issue. Not really touched the bike the last few months but the recent weather has enabled me to start tinkering again.
Hopefully by Monday I’ll have got the jetting better although it’s running pretty sweet now.
I got the 2-1 manifold with the bike although making one would be relatively simple provided you have a bit of knowledge with welding and patience. They can also be made with PVC or copper piping.
This bike has caused me plenty of headaches but it’s getting there now. Only had it a year lol
