Did 5th gear not make a noise when riding her?
I'm thinking about Morocco Sandraiders next year.. Wanted to make my own way there though - maybe ferry to Morocco or trailer the bike to Gibralter then ride from there. I hate flying!! Riding there would also considerably add to the adventure.

Yes, my apologies for going dark on the forum for a while, work got in the way after the sumemr as is so often the case and I have been pretty much away from home / workshop since.
That said, we have made a bit of progress and uncovered some challenges.
From a build perspective - engine all back together and whilst I didn't go through the full paint / cerakote process, I did throw a lick of VHT over the barrel / head to tidy them up a little.
I also managed to get engine etc back into the frame and get the wiring loom mostly in place, but seem to have hit a bit of a snag
Whilst I managed to get power through the system
I am struggling with a spark issue which I have resurrected in another post "1spark" seems I have a break or bad connection in one of the CDI generator wires.

You are making seriously quick progress! Thanks for sharing.
Picked up a non registered, non runner yesterday and came across your post when doing so research in to where to start with the project and what upgrades to do. Aiming to do some Wales trips next summer and aim for SR 2027.
Keep up the good work.
Ollie

Based on some of the recent issues I had with the ECU and sparks I have decided to go through and ‘upgrade’ some of the connectors on the bike.
I am aware that this will cause ‘plug and play’ challenges but will preempt that and take some spares with me.
I am much more comfortable knowing I’ve got solid waterproof connectors than worrying about what happens if I need to change over a part.
I went with this style of connector as they are pretty easy to work with.

they're referred to as AMP type connectors, really good, arguably the best solution.
Make sure you have the correct crimper.

Hi all,
I am new here because I too have bought a 3AJ for Sandraiders 2026 in Morocco.
My bike is a Red/White UK bike and has just completed 76K miles. It's in good condition for 1990 bike with high mileage.
The engine is out and has gone for stripdown and assessment.
I've just readthrough the posts and was debating what to do about the wheels - as they seem ok!!! - but I think a rebuild should be the correct thing to do. The other issue is suspension.....I am thinking of just servicing the front forks...fresh oil new seals and leave the springs as original.
I'd like an opinion on what is best. (Cost is a factor for me). Also, I've read that a lot of people install a Wilbers rear shock. What type of Wilbers is recommended. I'm now going back into the garage to renew all the linkage bearings and wheel bearings.
As for a battery I've been told to use Lead/acid as Lithium doesn't perform well in the 36 Degrees heat of the dessert...apparently. I will post some photo's up and hopefully meet some of you in the dessert next year.
