Sorry Cheesy, I had a brain fart and thought you were in the UK

Cheesy - are you coming down to the rally next month?

My Velosolex 3800 was going through fuel like a Harley on speed.

Finally worked out the fuel tank had split at the joint - didn’t leak when stationary though.

I JB welded the seam and it’s been fine ever since.

Have you worked out the size of rear sprocket your going to need?

Well done, grand job

Ron, personally I think that would be pushing it a bit too far; Enfield frames are not the most robust materials and I’ve known a few problematic ones that cracked under diesel power. I have 4 Enfield Bullets and the Kubota equipped one is definitely the heaviest, coolant adds a lot of weight after ...

Mine tops out at 68 mph - that’s 3600 rpm and I haven’t touched the regulator settings so it starts holding back at 65. I did a 200 mile trip last Monday to check on the belt drive and dry clutch setup as I’ve lightened up the clutch springs, and it’s returning a shade over 140mpg (imperial) so that...

Firstly congratulations on getting the bike back on the road. If by ‘Hunting’ you mean an uneven tick over producing a bit of black smoke then this is usually caused by setting the idle too low and the fuel screw too high. Also if you have an ‘overfuel’ plunger on the end of the rack limit, this wil...

I know it’s been an odd year for everybody, but why oh why does it always happen just before heading off to a rally? 1) the battery has died on Sluggy 2) the camper electrics went and let the smoke out 3) the bike trailer has a flat 4) the solar panel for the van may not arrive in time 5) the fuel f...

I spy a Velosolex....good man.

Nice start, are you sure you couldn’t up the motor to a 15LD440 or 500?

Have a look at the Diesel Wiesel setup as they use a Suzuki gearbox that was counter rotating but the engine is installed backwards.

You try being retired; there is just soooooo much to do.

Sh*t, better put the bike back together in one piece....

Well even though we are now allowed out for a ride I’m gonna miss the Big Knock. So I’m buying a raft of widget Guinness, putting the tent up at the bottom of the garden and cooking myself a burger on the BBQ followed by talking bollox to myself whilst sitting around a campfire for the evening. Frid...

I am being realistic with the speed I am hoping for The greaves and the custom bikes using 8 to 10hp diesel engines only do 50 or so due to gearing and low rpm of the diesel I’m going to disagree with you here, in my 15 years of riding Greaves and Yanmar clone motors - believe me 10hp will only jus...

I think you need to be a little realistic with your expectations... the Greaves 6.5 HP that RE used in the factory Taurus diesel couldn’t top 40 on the flat. The scooter transmission seems promising, be careful with the idle speed as the Hatz motor will still idle over 1000 rpm and with the upgearin...

Since building the Kubota Z482 into an old Enfield chassis, I have been using the original chain drive and supposedly wet clutch setup with just a drip feed for lubrication. My last trip to Germany proved tough on this setup and the oil line fractured and left the chain running dry. I can’t use a co...

Notwithstanding my fading memory.

Doesn’t anyone remember if we had a member who was involved with the production of the Morgan type JZR 3 wheelers?

I have an owner in Germany trying to get it through the registration process and needs some help with the date of manufacture for the frame.

I’m actually very pleased with the Kubota powered Enfield, the primary chain demise was my own fault as the oil drip feed pipe had failed and I didn’t notice. Really it does need a belt drive so I’m saving up my pennies as they are rather pricey. It is the biggest motor I would fit into an Enfield t...

It’s simply impossible to ride in a sidecar and not smile.

Usually a grimace of abject terror, but that can be seen as a smile from a distance.

Did you do the run to Durness and back in one hit Mark?

So far on the Kubota Enfield I’ve chewed through one primary chain, a battery and quite a bit of coolant - all in 4500 miles.

The only way you are going to find the engine max temp would be to install a temp sensor and do some heavy load testing. Do you have any 33% hills locally? Air cooled motors can run very hot, for example my Velosolex moped can get over 200C and I’ve tested Chinese pistons in C90 engines and they sei...

They need a flat surface so just drill 2 small mounting holes on a top fin and use some thermal paste on the contact face as you would when heatsinking electronic components.

Plenty available on eBay, make sure you use a relay...

BTW unless you have a 188 motor with the removeable plastic fan don’t go to all the bother of grinding off the impellor blades just fill up the voids with builders foam until you are convinced it’s the right thing to do.

Ask me how I know.............

If it’s an air cooled lump then it’s easier, just but a temperature switch (perhaps 150C) and use this to ground activate a relay and fan setup. Heat in heavy traffic or stationary wouldn’t worry me as diesels gulp full air and little fuel at these times but full throttle climbing is where you will ...

There are quite a few options for triggering an electric fan, rads designed for use with electric fans have provision for a bolt in temperature switch, otherwise there are versions that can be strapped to the rad tank (Kenlow used to sell them). Or there are inline versions that can be installed mid...

It’s the first 10 years (around 120,000 miles), that can be difficult. You should find the following decade somewhat easier, things will become routine, (clutch rebuilds, wheel bearing replacements, steering bearings, tyres, chains, gearbox bearings etc etc etc). At around 200,000 miles you should t...

The bolt holes down to the frame tend to be different between the manufacturers however the drive side bolt pattern is SAE.

I’m hitting the same problem fitting this...
