As I'm getting close to finishing my '81 Z750, I thought I'd give you all the heads up on what's next. This lot-which cost £100 with the reg no GFV***    Which used to look like this- A 1955 BSA C10L 250cc sidevalve  but it's not being fitted with it's original 9 bhp 250cc sidevalve engine because it's being fitted with one of these- Kipor 10hp single cylinder diesel  A relatively easy conversion as it has an electric starter to go with the kickstarter on the separate gearbox and it comes with it's own wiring loom and charging system which puts out a healthy 13.6 volts. A man 'in the know' told me to expect 180mpg from this set-up. I commute 15 miles a day mon to fri so, if I used it for 52 x 5-day working weeks, I would have to fill the 4.1 gallon tank 5.5 times a year. Annual fuel costs would be around £100! All the looks of a classic BSA with no leaks, breakdowns and constant fettling every week. It'll do (depending on the gearing) around 65mph but will be comfy at 50-55mph. The paintwork is going to be either GPO livery or old school AA patrolman because a fellow Vmcc member has a lightweight sidecar chassis that they're willing to donate. Something along these lines-  Great for all your shopping needs. Can even teach the wife to ride it so she'll feel she's somehow involved with the project  Likely starting date will be around late June/early July |

That's class! 180mpg as well, you're making me want one for myself.

Looks like a great project! Will be keeping my eye on the build up  A friend of mine was going to build something similar with a Harley frame and a big generator engine. |

Looks like an awesome project. Near enough to zero fuel consumption and it will probably be faster than a standard one with the side-valve! Win-win situation. ;D

Now there is a bike to have once sorted.

I'm a member of the VMCC and our local classic bike club. When I started marshalling their runouts for them, I asked "What qualifies as a 'Classic' bike?" They said it has to be over 25 years old. Now, the Z750 is 28 years old but when I mentioned this, there were a few 'tuts' and murmurs about it not really being a classic. What these 'Purist Wierdy-Beardies' are really saying is that, as it's not a pre-70's Norton/BSA/Triumph/Velocette type machine, then it's not a real classic. Hence the purchase of the BSA. When I've finished with it, it'll still be a BSA as it states on the V5. It'll just be powered by something else! If they start on about the engine not being original and doesn't belong in the bike or it being a shame to ruin a classic BSA, then my argument is this- Why is this any different to a Triton(Norton frame/Triumph engine)? That's as much a hybrid as this BSA/Diesel! No feckin' grey areas! The engine wasn't meant to be in that frame! As for ruining a classic bike? It was a pile of bits in a shed for 25 years or so and would've remained there if it wasn't for me saving it and getting it back on the road where it belongs! It's the same reason many of you guys take an old car and modify it. To make it more practical/powerful/economical and, above all, more enjoyable to own and drive. Looking forward to upsetting the 'Purists' If you want to try it yourselves, best to start with an older bike with a separate gearbox(pre-unit construction) as it makes life a lot simpler than trying to fit one of the Daf-type CVT trannies which increases the width dramatically. This set-up is only 2 inches wider overall. The motor is going to a local engineering shop to have a sprocket mount made to fit the output shaft. NB! If you go down this route, make sure the motor you chose doesn't have a tapered output shaft as this complicates what is quite a straight-forward project If this all works out well, I'd be happy to help someone else do a conversion as I think it makes a mockery of fuel prices and it's free road tax to boot!! A Royal Enfield 350 is a perfect base to start from as the conversion has been done many times and there's even a guy selling converted bikes on Ebay for a smidge over £3000 with warranty giving 130mpg (the 350 petrol returns 70-80 mpg) Ian |

Nice project. Out of interest, where did you source the engine and what sort of price do they command?

I pressume you'll be putting a more bike like exhaust pipe on it
and have the air filter behind the sidepanels
but can the engine run with out the shrouding so you can see it properly?

I pressume you'll be putting a more bike like exhaust pipe on it and have the air filter behind the sidepanels but can the engine run with out the shrouding so you can see it properly? I'm looking at running it through a Bsa style peashooter silencer after making up the header pipe which will be one of a good few things that will be sent away for chroming. The air filter will be mounted on the side of the motor a'la Harley D. Using a couple of Enfields for examples, the drive side (n/s) uses the existing primary chaincase modified to fit so it retains it's clean lines to a great degree-  The gearchange side (o/s) isn't as pretty but the shrouding can and probably will be modified to look a bit better although I'm not too bothered as it makes it easier to keep clean.-  BTW, I actually paid £200 as it came with a 1955 BSA C11G in a similar condition. I gave the C11 to a mate as a 40th birthday pressie because-1- he's been a good mate for years and has always been there to help with everything and 2- He always fancied a 'Classic' project and 3- I got the Z750 from a mate for nowt so I'm passing the gift along, so-to-speak. He's going down a different route with the C11. He's junking the 250cc OHV motor and box and fitting a-wait for it!!!!! 140cc Honda-copy Monkey bike engine with a turbo and various other goodies!! God know's how fast this thing will be but if the BSA-Diesel doesn't curse word off the Purists, his BSA C11-Turbo certainly will!!! He's started the dry build and is about to make up the mounts in MDF templates. I'll get some pics of it as it progresses in case he doesn't log on and post them here. We spoke tonight about what do do after these two mongrels are done. Plan A is get a post 1977 Yamaha FS1-E with a knackered, restricted engine as they aren't worth as much as the pre 77 bikes and fit a 140cc Monkey motor and turbo into that. Plan B is another pre-unit classic and fit the biggest, most torquey diesel we can. Something like a Hatz 800cc twin. It'll be a fair bit wider but it'll probably be able to pull top gear(out of 4) as low as 20mph. Another diesel-loving mate is on the point of getting a Cossack(Dnepr-russian sidecar outfit), junking the 650cc flat twin, lengthening the chassis of the bike and fitting a 1400cc turbo diesel from a car. It's been done before and makes it go from 65mph and 30mpg(weighs over 300kg!) to 100mph and 80+mpg. To give you an idea, here's one of my old Dneprs during the build-up. You can see what scope there is for a transplant  Right! I've rambled enough! Back to the garage! |

Stunned. This is the best thread I've read on here in a long time!

I've been looking at Diesel bikes myself. Don't have room for a project car, and don't have a bike license, but felt like building something "utterly stupid and useless " to me anyway.
Apparently there are a couple of guys who have used briggs-stratton/Daihatsu triple turbo diesels on shaft drive bikes, and also there are a couple of Chinese clone V twin 750cc diesels that make 20-25HP and can do 80, cruise at 70.
And an alternative for a gearbox is a snowmobile compact CVT. Same as the ones used on Minibikes and automatic gokarts but beefier. Users say they seem odd at first because revs rise then speed rises without you needing to do anything.
I did think about having a go at building an electric bike but that is a whole different thread.
And I really want to see how this one goes.

I'd forgotten about this thread!!
Sorry to dissappoint but the BSA C10L(along with my mate's C11G) are up for sale as we've decided that they'd tie up space in our garages for too long and we both would like the space back
We've decided to explore other avenues in the meantime.
There's an option of another Dnepr but it's bright purple and I don't think I can afford the Nitromors. ;D
Bit of an about-turn but I couldn't be ersed with something that potentially could've taken over a year to get on the road.
