The cam chain tensioner was replaced on my K1300 GT today, as during the last service (a couple of weeks ago) there was a report of it "singing" on the overrun, although I couldn't hear it with a helmet on. It seemed to be a fairly simple job (at least it didn't take very long!).

54,000 miles on the bike now, and hopefully a good few more to come in future!

I think it's time to remove and clean the radiator on my K1300GT after four years of use by me. I've no idea whether or not it's been cleaned before, however when I had the throttle bodies replaced some 6,000 miles and two years ago, the dealer said it seemed fine then. Now, however the fan seems to run for longer when it does cut in and the temperature rises quite quickly in traffic. Cleaning with the radiator in place has made a difference, however I want to ready the bike for next summer by doing the job properly. I realise that I might need to replace the radiator and have checked stock at the dealer, it is available from Germany with a 10 - day lead time.

I need to buy a suitable vacuum bleed tool (I have a compressor with a good size tank in the workshop already) and would like to ask for help with its selection, as at present I have no idea of the filler neck size on the radiator that the vacuum adaptor will need to fit to do its job. Could anyone who's done the job kindly recommend a suitable make of bleed tool or let me know the size of the neck on the radiator?

Many thanks.

I went to the dealer today, only to pick up a replacement pair of gloves (the dual chamber kind) that originally came with two quite different sizes between the "cool" and "waterproof" compartments. Unfortunately, the replacement pair were little better, so I chose a different type instead.

When I reached home, I gave the bike its normal wipe over and noticed a couple of streaks of oil on the left side of the tank plastics, and then when looking more closely I found a few spots on the left side of the top box. Eventually, I traced the problem to the clutch master cylinder, as much as anything because there was a "squelching" noise when I pulled the clutch lever in.

I called the Service Manager and explained the problem, to which he replied that he'd never needed to change a clutch master cylinder on a "K" series until a couple of weeks ago, when a customer turned up with the exact same situation. Anyway, it's booked in for replacement in a couple of weeks under the warranty package.

We are due to go to Wales next week for our annual visit to Radnor Revivals, so I will be taking our recently acquired Mercedes SLK that I bought for my wife a week or two back instead of the bike. I could take one of the old Honda's and I am sure that it would be no trouble at all, however my wife has vetoed that option as she says it wouldn't have enough luggage space or comfort for her!

My ESA seems to have stopped working on my last run out two - up a couple of weeks ago, When I next rode the bike (solo) it felt very firm and quite harsh, whilst the ride height adjustment did not appear to do anything, nor did the damping.

Today I rode out and, after quite a pummeling on a very rough section of road, the comfort level seemed to return to normal. When I reached home, I parked using the centre stand and, by switching between the ride height modes, could see the "sleeve" over the rear spring move up and down by around 1/4" or so.

Would anyone with a GT (ESA 2) be kind enough to take a look at their bike when it is next out and confirm whether the 1/4" or so of movement that I am seeing is about the right amount?

I realise that this will not answer the question of whether the damping is changing or not, however it will at least provide a starting point for any further investigation.

Many thanks.

Anyone visiting mid - Wales might like to consider this accommodation, which consists of five log cabins on a non - working farm.

It is motorcyclist friendly, with breakfasts delivered to your cabin door from the farmhouse if required. There is a nice pub about a mile away for other meals and Rhayader and the Elan Valley reservoirs are within half - an - hours ride.

The website address is: www.radnorrevivals.com and the telephone number is 07876 - 597697. Contacts are Bev, or Jack (her son).

I have a problem with the exhaust headers. When returning home on Saturday last I thought that the exhaust was louder than usual and upon close inspection yesterday, found that the headers have  pushed the weld out at the 2-1 junction.

I called the dealer today, quite prepared to buy new pipes as I assumed (correctly) that they are not a warranty item, however after booking me in for replacement on Thursday week he checked stock to find that there are none in the UK or Germany and, far worse still, the next due date for arrival of new parts is May 2021!

Does anyone have any ideas of where replacements might be found, even if only as a stop - gap measure? If not, has anyone successfully had repairs made to the existing pipes, if so where?
