Long overdue fork and brake service. Someone wants to ride her Sprint
I was doing something similar a few days ago, fitting new lighter springs into the forks of KG's Monster. We replaced the standard 0.86 to 1.0 kg/mm progressive springs with linear 0.76kg/mm springs. The new springs were shorter than the previous ones and we had to remove the original plastic spacers and replace with longer aluminum ones. As a bonus we also achieved a weight saving of 280g (0.6lb).

To give some perspective of how stiff the Monster's forks were originally, the springs in them were not only stiffer than the Sprint's OEM springs (0.68 to 0.9 kg/mm) but were also on par with the (0.8 to 1.0 kg/mm) Promoto springs I installed recently (and the ST+Me weigh about 90kg more than the Monster+KG).

Since then we've been for a couple of short rides, and KG is much happier with the new ride characteristics. The ride from the front now matches the rear which has improved since we fitted the Wilbers shock which also has a much softer spring than the original (570 lb/inch vs 750 lb/inch).

My biggest regret about doing the fork springs on both bikes now, is that I didn't do it years ago. It was much cheaper and easier to do than I thought it would be, and has made such a huge difference. For those people wondering about it, talk to your local suspension specialist, and get them to recommend/provide springs based on your requirements. Then watch some you-tube videos, or get a friend with experience to 'oversee' your efforts and have a crack. The ST forks are pretty straight forward, and if you wanted to go for the cheapest method, you could get away with not replacing the seals/bushes since you can access the springs by opening the top cap and dont need to separate the inner/outer tubes ( I went the whole hog since I used forks off the spare bike that had been sitting idle for 4 years). You will need a 1litre bottle of fork-oil which will be slightly more than you need to fill both forks.

A set of fork springs, seal and bush kits and a bottle of oil will cost about the same as 1 new rear tyre.........

Regards, Keef.

Installed an original Triumph heated grip set that I picked up on fleaBay brand new still in the box forAU$80.

View attachment 723519

30 minutes to install, how good is that?
I’ve installed a couple of Oxford kits before, but it’s sure worth the extra money for the Trumpy ones even at full retail for how easy it was.
My bike came with a set but the right grip has never worked. The PO was upfront about it. Oddly he was an electrical engineer but couldn't be bothered to fix it. I've looked into it but have yet to solve the problem-I'm pretty sure it's a break in the wiring to the right grip, but simply patching the break hasn't worked.

I've contemplated installing some aftermarket grips (I've seen others make the switch), which has got me wondering how OEM compares to the competition in terms of max heat and variability of heat. Anyone?

I have Triumph heated grips on both my Sprint 1050 and the Trophy. Each has only two settings, high and low but I have found them more than adequate for riding temps down to about 5 C, anything colder really requires heated gloves. I installed Oxford heated grips on the Suzuki and while the installation is not as neat looking - larger cables plus the controller - they do give more adjustment from 30% to 100% and they heat up much faster. Even at 100% I still need heated gloves at much below 5 C.

I have had Triumph OEM heated grips on both my Sprints, and KG has had Oxford heated grips fitted to her last four bikes. I second Ulster's comments above regarding the two types.
I'll also add that the Triumph grips plug right into the Triumph wiring harness which gives the advantage that the grips definitely turn off when the ignition is switched off (regardless of the whether the heated grips switch is in the off position or not).
The Oxford grips claim to have a voltage sensing cct within them and are supposed to switch off before your battery goes completely flat. I won't comment on the current generation of Oxfords, they may be better than the older types where this feature did not work as advertised. We only endured this once, after that we added a relay into the +ve supply to the grips and used a feed tapped off the number plate light supply to activate it. This way there is no possibility the Oxfords can remain on once the ignition is switched to the off position (obviously switching the ignition to 'parking lights' negates this). We have fitted similar arrangements to each of her bike's since then.

cheers, Keef.

Today, I rode the Sprint to work and back, the roads are still essentially empty and enjoyed the ride since it was much more flowing than usual.
Unfortunately after I got home, I went out to the bike to check the compatibility of a part that I had just found on ebay, but instead I spotted this lodged in the tread at an angle :
20200429 the ugly.jpg
I pulled it out with pliers hoping for the best, since it wasn't all the way in. At first it looked like I'd got lucky, since no great whoosh of air followed the nail out, but not so, it is very slowly leaking air.
I fitted the spare wheel on the bike and tomorrow I'll plug the puncture. I'll use it for commuting to work and use the other one for the country rides.

Cheers, Keef.

I plugged a rear tire on the previous set and rode it for at least another 7K miles, even on a week-long trip that, unintentionally, led me into a snow storm. Never had a problem.

Update on the tyre, its only losing about half a PSI per day. So I'll try running it as-is for my commute to work and back and just top it up after each ride. If it starts losing more than that I'll plug it. I've still got the other wheel for the longer rides into the more remote areas of our state (which we cant access yet due to Covid-19 restrictions but by the sounds of it we will be able in a few weeks).
Today I pillioned KG into the city so we could visit the main Triumph dealer for the state, since he has more parts on-hand than the closer dealer. They allowed me to weigh the OEM "SunStar" 43T rear sprocket from the latter SP3's that are a more modern shape than the older 43T from the 955 Sprints. While looking at available sprockets online I noticed the new ones have a similar profile to the Superlite RS7 sprockets. For the record, the OEM 42T on my retired ST weighs 849g, the OEM SP3 43T at the dealer weighs 808g. I will be going for the Supersprox 43T which are supposed to weigh 725g. The Supersprox 42T weigh less again at 612g but I want to try out a 43T on the back.
I tried an 18 on the front a few years ago, but for me, the difference was more than I was looking for. Although the acceleration and ability to lift the front wheel in low gears was fun, the bike became buzzy and used noticeably more fuel at highway speeds (where I spend more than half my riding time), so I reverted to a 19T at next the chain replacement.
According to my calculations, adding 1 tooth to the rear will give 43% of the difference of dropping 1 tooth on the front. Maybe this will be the perfect compromise, only time will tell.

We actually had a decent afternoon so I rode all of them today just to keep the juices flowing.
The locals all seemed to have the same idea so lots of aggravating mini vans and SUVs to blow past.
Out of all of them, I think the original purchase, the Yellow Banana, is the one that suits me the best.
It's small, light, fast, comfortable - you know, maybe KitNYC was on to something with the 955 RS after all.
I like them all but I could see being perfectly content with the RS.

We went for a ride today, we started heading out to a town we haven't visited since the covid-19 lockdowns began but yesterday we realised it actually sits within the 'borders' of the region that we are allowed to travel within. We got about 3/4 of the way there but then encountered bushfire smoke over the road. Since we weren't sure of where the fire was or which direction it was heading in, we turned around and returned to the previous town. We've been caught on the wrong side of road-closures before, and its both scary and inconvenient. Especially here, where its common for a detour to add 100km to a journey and suddenly all your time and fuel-range estimates are out the window.

Our state has just had its fourth day of no new covid cases and the restrictions were lessened over the weekend. So heaps of bikes were out today, its like a celebration, except when we arrive somewhere, all the social distancing rules are still in place. We can still buy food but have to take it away to eat it. It's good to see all the people making themselves comfortable in all sorts of innovative places. Today we had our lunch sitting on the pathway outside a community hall, just enjoying some shade and watching the world go by.

One last thing, last night while I was researching a new sprocket and chain set, I came across an on-line clearance sale for EK-530-ZVX2 chains selling for less than half price (try googling EK-530-ZVX2-clearance). It looks to me like the ZVX2 are being superseded by the ZVX3 version and this particular Brisbane based store is clearing the old versions out. Remember that the 1050 STs need 106 Links, the GTs need 116 links and the 955i's need 108 Links, and don't buy a chain that's too short...
Hope that helps someone out.

Changed the coolant after about 6.5 years, 2nd change for me, think there was another change about halfway to now at a dealer, not sure.. When I drain the old stuff, I get only about 1.5 liters. Yes, I remove the radiator cap, open the bleed screw and drain from the lowest hose on the water pump, following service manual directions. The service manual says 2.8 liters to fill. The good part - a gallon of HOAT is good for two changes. The bad part - am I doing something wrong not to get over 2 liters in a drain? Bike is on center stand; maybe should have it on side stand tilted so the drain is even lower.

A few days ago I posted that I found a nail in my tyre while I was checking the bike to make sure an ebay find was going to be compatible with the bike. Well that purchase arrived today. It's something that I just didn't think was available for reasonable money anymore, and a few years ago had started looking for a 2nd hand and even damaged ones with an eye for rebuilding. As it happens, I found it when I was looking for something else.

This is a New-Old-Stock item that's been sitting in a wreckers in Adelaide, South Australia for the last decade or so. The ad title didn't have Sprint or Tiger in it, instead it was listed as a Triumph 1050 Motorcycle Topbox and I only found it when I spotted a pair of white pannier in-fill panels and decided to see what else the seller had in his store. As can be seen it doesn't have the top in-fill panel or lock, but I still have the 3rd luggage lock for the active bike and a spare infill panel, so will be good to go.
My active bike currently has the box from the previous bike on it, which is pretty beat up and has been repainted once already. Now I'll be able to take my time stripping back the old box and refurbishing it a second time. (It had a little adventure of its own about 7 years ago when it detached on a very bumpy road and had to be patched up and painted with textured (bumper-bar) paint)

Cheers, Keef.

Did you remove the thermostat cap? Did you try to blow compressed air through the hole?
No. In my naivete, I just followed the shop manual's directions to the letter. In all previous vehicles I owned, the thermostat had a bleed hole which should have allowed the coolant in the pipes to drain; guess Triumph either does not have a hole or it is not big enough. I waited about a half hour to drain to give it lots of time. Next time I will break open the thermostat housing and see if that makes a difference. Which hole do you blow compressed air through? Thermostat bleed? Radiator cap hole?

engine thermostat hole w/ a rag around the air blower.
edit: the hole where the thermostat fits. You may use this opportunity the check the thermostat opening temp (water in a pan...).
The coolant may get stuck in various cavities inside the engine. In fact I blow air everywhere. Then I rinse w/ distilled water.
BTW, yes I usually find such a hole on cars. There's none on triumph engines. Perhaps as well as on any bike.

Yeah I was shocked. At first I didn't even realise it was NOS, I just figured it was another busted up one from a wrecked bike. I have seen a couple on pinterest a few months ago, one was pick-up only in Netherlands and the other had a broken-off lock mechanism, and I wondered if I was just seeing one like those.
20200429 topbox ad small.jpg
But then I read the ad properly and realised that the hole in the front is for a new lock to go in, and I vaguely remembered being given the 3rd lock for the luggage set from the Previous owner of my active bike. So a mad search of the places I have bits of Sprint stashed eventually turned up the lock. Meanwhile KG had also found a set of 3 locks on ebay, but finding the one we already had means I could have a matching set of keys for the whole bike again (instead of carrying around one of the old-bikes keys that only opens the top-box).
Then I rang the wreckers, confirmed it was still there and arranged the purchase. It turns out that the wreckers bought all the stock from some Triumph dealer that closed shop ages ago. Unfortunately he was pretty busy and didn't want to spend time telling me what else he had, so I'll just have to check his website every now and then and see if anything else pops up.

Coronavirus travel restrictions still in place in the UK, so no leisure travel permitted. A 180 mile round trip to earn some shekels, so that's not leisure travel. Only the second time out on my Sprint this year :(
