Hi folks. I've heard of a machine which seems to have a non-standard engine, and I'm wondering if it was ever fitted as a limited run option. The bike is a 1956 20S, and the strange fitting is a 225cc 1H engine. Was this a factory fitted engine or has someone built a bitza? Mr Sparrow's excellent book makes no mention of a 1H being used.

I also have a record of a 1H engined 1957 20T with an S McCarthy, Lincs in 2015 frame number of which is 7049T.Last edited by John Wakefield; 17/03/2016, 11:02 PM.

If any engines were supplied to Greeves it would almost certainly been for evaluation purposes, as to my knowledge there are no records of any Greeves model being fitted with a 1H. Unfortunately we cant ask Rob for the source of his information on this particular listing as he is no longer with us. RIP RobLast edited by John Wakefield; 19/03/2016, 10:37 PM.

Strange engine.
A few years I put a 1H engine into a DC frame as a temporary measure to recover it's reg.no. The exhaust port is near central therefore partly obscured by the frame beam,making exhaust pipe bend very acute.Perhaps this is one reason Greeves did not use this engine. Les.

Stewart would like a bit more go so wonders if he can fit a 2T 3T or 4T twin, and where could he get some engine plates.
To my knowledge the 1H (and 2H) singles use the same fixing as the twins so I would think that its a simple job to swop engines using the existing engine plates, obviously a new exhaust system would be needed. Can anyone confirm this & would the chain line be correct?Last edited by John Wakefield; 11/02/2017, 09:45 AM.

I see you are selling your 1H special Stewart McC https://www.ebay.co.uk/itm/254614292...i4SfIHhQMkmo9s Nice bike for the back lanes and as the 1H uses same engine mounts (as I mentioned in my earlier thread) as the 2T 3T & 4T twins it would be a straight forward job to fit one of these.

I put a 1H (225cc) in a Greeves Roadster frame about 3 years ago but it was much heavier than the 197 8e it replaced so not really any faster. I had to set the engine back to get exhaust clearance. I did find a reference in an old motorcycle magazine to a trails result for a 225cc Greeves so maybe there was
one !

No I dont think so, that would probably have been a bored out 9E, the 1H as you say was a very heavy engine with no more power than a 9E and gears not suitable for trials. The 1H was never fitted by Greeves in any type of bike, it was mainly used by Francis Barnett in their models 71 & 75 Cruiser, and James in the K12 Colonel. Frankly I cant see why Villiers bothered to make a 1H or its bigger brother the 2H (250cc)
