That exhaust looks brand new Great effort Alex ! I'm so pleased you won the right exhaust for the bike - I think it really suits it and keeps the Lc theme - the exhaust looks like it's straight off a 2/350 !!

So, after a while in hibernation I'm back on it.
Not using an oil pump so that shaft had to come out...
So now I need a blanking plate. Wondering if an LC or RD one will fit. I'll measure that up tomorrow. And I could have sworn when I picked up the engine I had the cover that goes over the pump. If I DO have it I can't find it! And I may need a rubber grommet for the oil pump cable...
Next put in the exhaust gasket and that was all the time I had to work on her today.
Apart from a few odds and sods all I need is a damn carb. There are 2 types with 2 different inlets. Fowlers shows both but they don't have any. eBay has loads of carbs that won't fit my inlet, yet no actual inlets at all. It might be a case of buying one of the 'wrong' carbs and getting my inlet machined to fit. Meantime I have other jobs to do including finishing the tank and getting the frame welded. But I'd like to get the engine going first!

Some cracking news. My truck is fixed! Turns out there are four bolts on one side of the transfer case but I couldn't see them as the chassis rail was hiding them. Dropped the tcase out and to my horror one bolt was missing, one was dangling there, one was sheared off and the last one was actually on. Got the sheared one off with heat, swearing and mole grips. Heaved the lot back into place and bolted everything down. Drives perfectly now!
So...this means I can concentrate on the Popsicle. The carb issue. Might take a punt and get the 'wrong' but right carb and adapt the inlet to accept it. That's all it needs to run. Then the usual welding ensues and hopefully I can get a day time MOT!

Dusty there are two carbs. One just mounts directly onto the inlet via a metal tube and to be honest I have no idea how that would work properly. The other mounts on via two bolts. And a gasket. That makes sense to me. These carbs are widely available and cheap (ish). About £40 new. There is only one of the other carbs for sale out there and it is a total mess missing loads of parts and that is also £40. Next time I see you I'll show you what I mean. But the good carb needs the correct inlet and they are nowhere to be found, so that's why I'm thinking it might be worth a punt and get my inlet adapted so the carb can just bolt on.
As for Piglet. What a transformation. Back to her usual tyre shredding self again lol!
How about drilling a bigger hole in the inlet, get a piece of aluminium tube made the same size as the carb welded on, then use a short petrol resistant rubber/silicon tube to join it together? Or find a rubber inlet with the same bolt fixings?

Well, there are no rubber inlets...until now lol. After searching under DT50 I found them. However I need to be sure they fit before I buy one so I will bee checking to make sure tomorrow. Failing all that at least I now have a bunch of options, thanks Rob for yours. Everyone here gives really invaluable advice! Once I have a carb on there all I need to do is minimalist wiring (no battery needed) and give her a kick...

Also possible. Going to ask the seller of the rubber inlet the dimensions but I doubt he'll reply as it's a huge eBay company. However it appears the DT and RD are the same engine. Apart from the DT having an off road exhaust. Can't imagine why Yamaha would alter the barrel for a different carb so fingers xxd I can use the rubber inlet.
Do you know what year your engine is Alex ? Fowlers have pics, albeit not great quality, of both the carb types, and yours looks like the early carb which should have the clamp built in like the one Steve linked a pic of. If that can be confirmed I would try and find an alternative carb of the same design that will work as it was originally designed to do. That way you are nearer to getting it right, even if you have to adjust jetting. Maybe speak to Allens - the carb people, or ask the question on the aircooled forum. If all that fails then the other options are there.
