Welcome to my blog!

I had a question asked of me that is very pertinent to the fact of the very real scarcity of OEM crankshaft shells.

Here is the question along with my answer:

I have a question about con rod bearings for the GL1100.

Is it possible to use the con rod bearings from cylinder 2&4, the shells with oil holes, on cylinder 1&3 rod/journals whose shells that don't have them?

Thanks in advance for any info. 

Hello Grant,

There is obviously no problem using them in the rod caps. I have struggled to find out why Honda only specified oil holes in #2 and #4 but have never seen anything official from Honda.

My theory, and it's only a theory, is that due to the direction the crank is turning, sufficient oil is thrown up to the #1 and #3 cylinder walls to not NEED the oil holes, whereas the opposite side does. I seriously doubt if using the shells with holes in the #1 and #3 would cause any problems from the extra oiling other than possibly some oil burning if the rings are worn. The oil pump should be able to cope with the extra needed delivery.

Strangely, the GL1200 has the oil hole in all the rod bearings.

So that gives you two alternatives.

Try to find just two shells without holes just for the rods, or take the slight chance and use the ones with holes.

Anyone visiting the site recently will have maybe noticed some problems with it.

The immediate ones have now been fixed but for how long I don't know.

The site is old and based on Adobe Flash. Adobe pulled support for Flash in January. We had been warned for some time that this would happen, but to be totally honest the thought of rebuilding a new website from this one, with over 100 pages, was something I just put off time and again.

However, the site could still be seen by customers (this is where I don't know for how long) but I couldn't do anything with it; no additions, no alterations, nothing, as the backend was unavailable.

Yesterday I got notice that Moonfruit (the host) had come up with a workaround (hurray, at last. They really are pretty useless!) which has let me into the editor.

So what you see now is current as of this date.

Unfortunately, as it is still on the Flash base, it will show up in your browser bar as unsafe. This, I am assured, is not the case as the site is now edited on a specific unique version of the Firefox browser.

So that's where I am at the moment. My guess, just a guess, is that a new HTML5 site is going to be absolutely necessary eventually and I have made a tentative start on it.. Don't hold your breath for it!!

Now in stock.

Very limited quantities as the supplier screwed up by sending half the order with the wrong substitute belt!

That will get fixed, eventually!

At long last, a new blog post!

I hope you are all keeping safe at this somewhat fraught time.

Well, in spite or rather because of the virus, I have been super busy with carbs, as owners have been able to spend time in the garage or workshop. So busy in fact, that I have got nothing of my own stuff done.

So I am halting carb rebuilds forn the end of this month for two months.

Another 'at long last' - I will have timing belts available from the end of this week for GL1000 / GL1100

The front transmission cover kit has been overhauled and now includes the 3 alloy crush washers that everyone forgets to order when replacing or overhauling the water pump. Now shipped from me.

Due to the virus, Ray was finding difficulty shipping the water pump kits out fron Germany, so they are now being shipped direct from me in the UK.

Now a biggy!!

I'm sorry, but for you guys in the States the shipping has gone through the roof!

Due almost entirely to Mr Trump pulling the States out of the 145year old Postal Agreement, shipping has gone up by almost 50%. I can ship a pack of radiator hoses to Canada for £10.50; the same pack to the States is now £15.20 ! Royal Mail divide the world into postal three postal zones; the States is the only country in Zone 3.

Daisy from Wemoto has again asked me to show you the new stuff from the Supporters Club charity that raises money for the emergency helicopter that saves riders lives in the TT and the Manx Grand Prix.

This could make a nice Christmas present for a friend or yourself. Would look great in the workshop!

At this price, why not have one in the house too.!

There are new Tee Shirts as well. I've had some difficulty re-sizing the images she supplied to fit this blog but the link is in the description below.

Here is the Press release:

Classic TT Manx Calendar released to help charity

Buy a £2 Manx calendar and help support motorcycling in the Isle of Man.

Wemoto has teamed with Bill Snelling to create a Classic TT Manx Racer calendar. It features some of the most iconic moments in TT racing history from the 1920s to 1990s, taken from Snelling’s photo archive. Famous faces include John Surtees, Carl Fogarty, Joey Dunlop, Steve Hislop, Sammy Miller and Mike Hailwood.

The profits from the sale of the calendar will go to the Manx Grand Prix Supporters' Club (MGPSC), which provides medical assistance to riders on the track and supports them while they recover from injury.

Since 2015, Wemoto has been selling merchandise to visitors of the Isle of Man’s Festival of Jurby, with profits going to the MGPSC. The Manx Calendars are a new way to raise money, while this time celebrating TT racing as a whole.

Designed in-house and finished in classic black and white, the calendars will look stylish on any wall. In the run-up to Christmas, they also make an excellent gift idea for friends and family. A fantastic way of both commemorating historic motorcycling moments and helping current riders.

The calendars are available now at Wemoto, part number we-manx-calendar/AG5782

Now available at Wemoto

Ok, here's a question for the whole world. Yes, I really mean that.

Other than the listed models in Randakk's charts (, which I believe only pertains to the US market, I can find no information on which model of carburettor through the years was fitted to GL1000s throughout other markets.

It seems that '75s ALL have 755A with the round alloy operating arms, which were discontinued very quickly.

The vast majority of (supposedly) 76-77 carbs I get in from UK/Euro customers for rebuild are 755B, all of which have the same jetting as the 755A. I can find no differences between A and B, so I don't know why the alternative letter.

I have heard of carbs marked 755C but never had any of those in and no idea where they were sold.

I think ALL of the 3200 '76 LTDs were fitted with the 763A but again, you may know different.

So what I would like to ask is for those owners in different parts of the world who have unmolested '75 – '79 machines with original carbs to email me:

the year (VIN would be useful),

the area it was originally sold in,

and carb number.

If you have something with a model number different to the ones already mentioned (like the 775C) it would really help to get the jetting sizes too.

I will put the info in a chart for everyone to see.

If you have been visiting over the past 6 weeks, my apologies for hiatus. Fell down a flight of stairs, breaking my right arm and fracturing a vertabrae. Healing is going well but still unable to do much.

Certain items that require me to make up, like the radiator hose kits, will have to wait a while yet. Others like the stainless brake pistons are suppiled direct so that service is unaffected.

I will be away again until the beginning of Aug; hopefully to be back to full strength by then.

By John Evans, Oct 31 2018 12:34PM

Ok, first up.

You may have seen from the Index page, there is a sale on the stainless steel brake pistons.

Most of them are reduced in price but understand, ONCE THEY ARE GONE, THEY ARE GONE!!

They are NOT going to be replaced.

Next: I now have stock of the best fix for broken float pin towers on the GL1000. GL1000 carbs, good ones at least, are getting scarce and it is SO easy to break a pin tower when trying to remove the pin. Trust me, I know how easy from experience.

For those of you waiting for the Alloy Filters, they are in stock again. Sorry it's taken so long.

Plent of black, silver and a very few metallic blue and metallic red.

I know this will please many of you!

Due to the number of inquiries I have had, I am starting the Carburettor Rebuild Service back up again. Initially this will for GL1000, again using Randakk kits, but I envisage also offering both this and a cheaper rebuild eventually using an alternative source. The Randakk kits are ordered, will be here in approx 2 weeks. The cheaper rebuilds are still some way off as certain parts are proving difficult to source.

GL1100 Carburettor rebuilds will follow soon.

If this is of interest to you, let me know and we can get you booked in.

The viewing figures for the site are gradually dropping off, week by week.

Now logic says that, of course this will happen. The bikes are getting older, more and more are getting to the stage that they are not viable to maintain and thus are being scrapped.

It's a great shame but it is a fact of life that some good bikes are also getting scrapped since they are worth more in parts than as a running machine.

Ok, so we all know that. What I am asking here is, how do you view this site? That is, do you view it on a desktop PC, a tablet or a mobile phone?

Are the numbers going down through it not being very mobile friendly ( I do know that is not! ).

I have tried to make it as compatible with all platforms, as much as I can within the limited capabilities of the hosting platform format.

They have recently brought out a newer version, in beta, for active pages. These are pages that automatically re-organise themselves to fit whatever they are being viewed on. I am trying to find out if it is worth while spending the huge amount of time and energy to convert all the over 100 pages of this site.

Your input would be much appreciated. Thank you.
