Confirm engine number
captaink:
Hi, I have ordered some engine parts for my 750 Rickman but every time they seem to have trouble with the engine number
It's on the v5 as the original 1979 rickman engine
It's a black F2
Serial no. F2750E 2248782
Any thoughts as to confirming the age
Johnwebley:
I always thought they (Honda UK ) used the frame number to give model and date of manufacture,
maybe Bryanj could use your engine number to give you some idea

Silly question, but who are you trying to order parts from, some places are much better than others, I have found a lot of high street Honda dealers really can't be bothered to look things up properly, I have even had one turn round and say " Try a scrapyard where something that old belongs!" I was only wanting a kickstart oil seal, needless to say I didn't go there again!

I just wanted to confirm the engine date as the frame has a rickman serial number.
But David silver says it's a k5 number but it is an f2 engine for sure so later.
I have located a supplier of F2 parts being Suzuki performance spares ltd. they do Honda parts as well and have in stock F2 APE valve guides, springs etc. F2 valves are kibblewhite and delivery of about 2-3 weeks.
I have ordered these so the head overhaul can progress.
They also do the 836cc big bore kit.
