Due to the mould for the swing arm seals being lost, mislaid, vanished into thin air etc., my GL1000 KZ (suitable for all years) swing arm bearing kits with our Randakk/WinGovations seals are going to come to an end. I have the last lot of seals coming over, should be here in a few days, enough to do 20 kits.

So first come, first served.

I just had a note from Wemoto thanking us for the help in raising funds for the above fund:


Hi John,

I hope you're well. I'd like to thank you for helping to promote our Jurby T-shirts on your blog. The check with the final amount raised this year has now been handed over to the MGP Supporters' Club - £16,258.48, which is a huge increase on last year's £10,655.92. I've attached a press release about this year's funding and an image of the check, for if you wanted to post anything as a follow up to your readers.

Thanks again for your support with this - we're very happy with the amount raised and that the money will go towards supporting such a good cause.

Kind regards,




Huge thanks to all who bought the T-shirt and helped out with this amazing response. I will let you all know if / when there is another promotion.

I have reluctantly decided to put a hold on the carb rebuilds for the moment.

Partly due to the vastly increased costs to me of the Randakk Master kits (Absolutely no fault of Randakk. Blame leaving the EU process for dropping the £ down the toilet and the USPS for their increased shipping.)

But more than that. As time marches on and the carbs sets arriving for refurb are also getting older, they increasingly are taking more and more time to rebuild to a decent standard. Instead of an average of around 10 hours for a set of GL1000 carbs, it is now around 15 hours.

Again due to the aging and more and more to the fact that others have been delving into them, I find that they are needing many more new parts than before. Bent float pins, porous floats, chewed up drain plugs, broken plastic buttons etc; this can make a real big difference to the final cost..

There is a limit to what I can charge for a rebuild. None of my prices have been increased since I started this way back in 2010.

To make it more realistic, the basic clean and rebuild would need an increase of £50, taking a GL1000 set to £340.

So you tell me............Is that a figure that would put you off or am I still in the ball park?

Gentlemen, I am rapidly coming to the conclusion that the carb rebuilding service will soon have to close for a time, for a number of reasons.

This is mainly the result of the stupidity of this county's decision to leave the EU.

It has caused the value of the £ to drop through the floor, making the brilliant kits from Randakk very expensive. Combine that with the increases in the USPS shipping rates and much more aggressive scrutiny of incoming packages by the Customs and the whole issue is becoming untenable.

The last order I had direct from Randakk cost me $192 in Customs, VAT and Royal Mail charges, on a shipment costing $650 inc shipping.

so, I'm thinking to give some time to allow the exchange rate to steady and hopefully rise back in my favour.

Secondly, I get carbs in from all over the world. Currently, due to the EU regulations, there is no problem with the Customs for EU based sets sent in for rebuild and return. This is most definitely not the case for any coming from outside the EU. The paperwork is a nightmare.

So who knows what will happen once we leave the EU? Are we going to have the same problems with paperwork no matter where the carbs are coming from? No-one can tell me at this time.

I am reliably informed that miracles happen; frequently . True or not, I am finding that I am being asked to perform them, more and more frequently.

Well, it may be because people believe that I am too wonderful for words and that my skills are almost alien in nature. These observations, while undoubtedly true, are becoming a source of difficulty as my stock of miracles is getting severely depleted.

So please, next time you want your carburettors rebuilding, please take a few moments to clean them off and really look at what you expecting me to be able to accomplish wth this block of rapidly disintegrating alloy..

Be honest with yourself. Take the float bowls off at least and see what's inside. if they look like the carbs in the bottom picture on my carb rebuild page, you are probably expecting me to use up some more miracle stock. But sometimes no amount of miracles, magic wands, oofle dust (older UK readers may know that one!) etc. can bring carbs in that condition back.

But I will always try for you.

You have to understand though, a load of extra work is going to cost you. The prices on the page are for a straightforward cleanng and rebuilding. The odd problem during that process can be coped with, but I have just spent 18 hours trying to get a set of GL1100 carbs sorted out. And these are relatively smple to rebuild, averaging about 8 hours including some polishing.

A number of you have asked about contributing to the helicopter fund, without buying the T shirt.

Very altruistic of you, although why you wouldn't want on of those shirts is beyond me!

So here is a direct link to the fund organisers.

Many thanks to all who have seen this as a worthwhile thing to do.

By the way, if you don't know what thwe Manx Grand Prix is all about, may I suggest that you do some research. Vintage and historic racing machinery of all makes and classes. Bike you have never even heard of, as well as the ones you know but have never seen in action.


These rare and valuable bikes are used as they were intended to be used, HARD!

This will give some idea of how hard!

We can all use a nice new T-shirt for the summer. Here's your chance to have a great looking vintage style T and do your bit to help a very good cause in saving lives on the Isle of Man.

At only £10 / $15 plus shipping it's a real steal. Why not get two?

Buy a Wemoto Festival of Jurby T Shirt and help John McGuinness, Conor Cummins, Michael Rutter and Wemoto support the Manx Grand Prix helicopter. Rescue helicopter ambulances are used during the Isle of Man TT and the Manx Grand Prix practice weeks and race days.

In the event of an incident on the course, one of the helicopters will be despatched, complete with medical staff and equipment to get to the scene as soon as possible.

The helicopters, which have a top speed of 150mph, take an average time of five to six minutes from the first radio alert to arrive at the scene of an incident. Some parts of the TT course are quite inaccessible and speed is of the essence if there has been a crash, so the rescue helicopters are an essential life-saving service which racers rely on.

One of the helicopters at the Manx Grand Prix is funded entirely by charitable donations and all profits raised from the sale of these great Festival of Jurby Helicopter Fund T shirts, endorsed and signed by three TT racing legends, will go towards keeping this essential service in the air.

In case you are wondering what the Festival of Jurby is, Jurby on the I.O.M has the Island's biggest motoring museum and hosts this festival each year. Check this out:

I did this page as a joke for someone on one of the forums, but as it's the time of year to be getting out there and resurrecting that dying mechanical pony, it might just galvanise someone into action! :-)

Tidied up some of the website, plus a couple of new parts added.

On the home page, you will now find a page marked Parts under the Index button. I've done this to help you all find what you are looking for, as previously the system was a bit messy.

You may note that there is a couple of new parts added.

A stainless steel screw kit for the front transmission cover from my frind Robin in the States. This is a boon to anyone who has the misfortune to have to rplace a water pump, for reasons well documented on this page.

Also the excellent 7 volt regulators from Scott, also in the States. Notoriously unreliable as they get older, and damded expensive to replace with Honda parts, this is again something that you might not need right now but eventually, yes, you will!

......of head gasket failure.

I am rebuilding a GL1000 engine for a customer. This is, I believe, a fairly high mileage engine and one that has seen some abuse by previous owners.

As I always do, I run a tap down all the bolt holes in the block to make sure that the threads are ok and clean out years of accumulated muck from the bottom of the holes which may stop the bolts going right in.

What I found this time is enough to warrant a new Tech Tip.
