Lets build a SOHC for less than a grand
« on: October 19, 2019, 08:59:42 PM »
Hi, I am new to the project board and have built too many bikes but, never put a build tread up  :o

I have a agreement with the lady of the house that, we can not buy anymore bikes but, no mention of building any  ;)
I always read about how much these bikes cost to build and I know from first hand experience that they are not getting cheaper so, I have set myself a challenge to build one for less than £1000. Not sure if this is possible but, we will try.

Have got hold of a 500 four frame and have been donated a 550 engine, 500 hubs, 550 forks, 550 carbs, 550F1 tank ( thank you to all the members that have donated) and will be using parts from my stash that will need refurbing.

I will not be using any CAD or special tech stuff, it will be a tape measure, Vernier and cutting out bits of carboard to make templates.
I will not be using pods, clip on bars or any hi-tech electrics. 

I have stripped down the engine that was donated by a member who got it off another member and had been fully rebuilt using youtube vids  :o. The engine had about £500 of new parts fitted but, the builder had used silicone which had blocked the oil ways and destroyed the crank. But, a few £££ goodies can be reused like, the primary chain.

Today i started chopping the frame and putting a hoop on and trying a few parts out.

I had to read this post three times before I accepted it was you Graham.
Could be an interesting build as mine is a propper half assed restoration and cost way way over that.

Just to clarify about us not buying any more bikes. This is a joint decision and not me putting my foot down, which for anyone that knows Graham will know that he would take no notice of me anyway 🙄🙄🙄 and if I saw a bike I really, really wanted, I would buy it. We have so many bikes between us, of which over 95% are Honda SOHC/4's and we are not getting any younger, so its all about enjoying the ones we have for as long as we can whilst bearing in mind that eventually we will start selling some off. I sold 2 last year (and then Graham bought another one 🙄🙄🙄) so it will be a slow process getting down to just 2 or 3 bikes each, one of which will be the bike he builds in this thread.

What happens to the finished bike Trig. Is it a charity build to be auctioned off. That would be a great project for us all to get behind. Just a thought.

Less than a grand ...OK.... pinch of salt, as not all of us have freebies, parts stashes and the like .... but... as a guy with none of those things trying to renovate an old dinosaur with minimal spare cash...I have got my eyes glued to this one.

I hope to get some guides on what sort of old corroded tat can be brought back to life, what needs binning, and what can be done to reuse rather than just replace. Not corner cutting...coz I don;t see Trigger as the corner cutting type. But some solid tips and ideas :)

I am kind of hoping when mine is done that it will retain a bit of it's patina or character, and that's important to me. But my 3K budget is starting to look genrous ;)

Charity ! Yep, Triggers charity  ;)

This will be a retirement bike for myself and will be the last bike I build.

OK, hoop is welded on. Did a repair to the rear foot rest hanger. Made a seat pan. And have been offered a couple of ignition switch brackets but, decided to make my own.

Little bit of first and second cut on the fork lowers and brake plate. I hate polishing  >:(
