@oldman Honestly, I am building this RS and I have literally AJSutton exploading parts open wishing they were SVGs, I know this tool will be useful to restorers who want to know how it all fits together.
I did this back in the day. Bought a h3 kit that came with everything you would need.
My advice, don't bother. The beam pattern is incorrect and you end up blinding oncoming vehicles.
Not really what you wanna be doing, especially with cars.
so i have the Athena 125 head sat on my bench for when my bits arrive from MSP.
Before i fit my head onto the engine is it worth getting it ported and polished or would you say there already ported fairly well?
id like to get the most out of the bike when its built i have a limited edition custom made full stainless steel expansion chamber and silencer being made in portugal as we speek but that will arrive in 2 months ish il be getting a carb still got to find one so any tips or links ? and a techtronic CDI
