Iceni, go back to using IE instead of Edge. You will find it buried in Windows Accessories. You will then find all your favourites and passwords again too.

Iceni: It looks as though several 750T Guzzis came into this area, maybe via Kendal & Pit in Colchester where mine came from? Yours is the third 750T I know of locally.
Some days I find ride quality or lack of it is more noticeable than others: it depends on my mood and how tolerant I feel. Of course, having other bikes to compare with brings it to mind, especially since the roads around here get worse, year by year. No-one planes roads flat anymore: they just add another layer of tar and chippings over patches, especially on the back roads I enjoy riding. Maybe it's all a ploy by Ohlins to get us to upgrade! By the way, I've had mixed results from the nice suspension chappies at MCT in Stowmarket, who are really more into performance rather than comfort. I'm not sure I'd want to see their reaction if I took a budget Guzzi in for their ministrations... I'll let you all know if I make any progress on this issue. Thanks again for chipping-in!

Yep, I've got Hagons on my 750 S3 now, very good indeed!

In 1978 I bought my Mk1 LM from K&P, but the 750T seems to have been first registered in Guildford.
K&P never seemed that popular in the area. John Kendal was a good trials rider, but I believe he passed away a few years ago. Never knew or met the "Pit" element of the partnership, the general running of the business seemed to be done by Mrs Kendal. The shop was taken over by a scooter outlet, but that too has closed. Neither business was helped by the location of the shop - parking was a nightmare, even on a bike. Shame, really. Also, I've just been told that our local Ducati dealer has gone. Thought it was a bit odd when I rode there to pay a visit, on a Saturday afternoon, and it was closed. Back on topic, Ive set the top damper on number 1 to try that, and will then move it to no. 3 to see if it makes any difference. Don't expect much difference, though.

Altering the Koni damping adjustment makes an obvious change while static in the garage, but no discernible difference in ride comfort. I know I can be a bit paranoid about this, but it literally pains me when a ride on such a nice fun little bike is cut short by a bruised backside and mulched brain. In my area, road-surface quality is inversely proportional to interest value for riding!
I've chatted to Hagon, and will likely pop down to their works today to check out their 2810 adjustable upside-down shocks, taking the Konis with me and asking them to measure the spring rate on those before considering something softer for new ones. Simon at Bike Revival in the UK has undertaken to ask the Aussie makers of Ikons whether they can be fitted with alternative springs to suit lighter riders. As with Hagon, Ikon don't actually include the 750T in their lists but I think we are safe to assume it is the same 330mm unit as fitted to the 750SP, Strada and Targa. The Ikons are more expensive than the 2810s and have only 4 steps of damping adjustment compared with 10, plus of course they'd take a deal longer to get. Nick |

An update on the choppy 750T rear suspension:
To recap, the original Konis damped well but the spring rate seemed too high for a light bike and light rider. It looked to be difficult to get alternative springs fitted to Konis/Ikons, at least from source, so I opted to look into Hagons and their bespoke service. Of the available Hagons, I thought the best was their 2810 model, costing just over £200 the pair. It has 10 damping positions and fits 'upside-down', which reduces unsprung weight and also means they don't have to have a separater between the oil and nitrogen. The result of this construction is that the 2810s are much more supple than their basic model which has a lot of internal resistance to movement. The top-of-the-range Nitrons have bigger pistons and are only suited to heavy-duty use on bigger bikes apparently. So far, so good, and then it was a question of what springs to fit on them. Hagons measured the Konis at 14kg/cm, which surprised them because their stock recommendation would be 16kg! Anyway, I left them with a pair of 10kg springs fitted to the 2810s with guidance as to how to evaluate the action based on how far the bumpstops got pushed down when on the bike; static sag and all that. It didn't look as though there'd be enough travel left so I immediately swapped them for 12kg springs, which is what they were going to give me anyway. The springs are chromed and skinny, but that's all they had. Today I took the bike out and reckon it does ride a bit better over rough roads. After a few bumps, the bumpstops on the rod have been pushed right to the end, so at least I'm getting the full benefit of what is not a great deal of travel anyway. I can play with the preload too of course to give a bit more travel. I had the damping set to 3clicks above the soft end, which gives an obvious damping effect on the rebound as one pumps the bike in the garage. I don't think there's much more to be done to improve it, and at least I feel I'll now be able to concentrate on the excellent handling and fun to be had with this bike, rather than having my teeth rattled all the time. I wouldn't choose this bike for a long journey though, but that's not why I bought it. The swingarm bearings are fine, by the way, so I think the suspension action is what it is. Perhaps if I hadn't gone up a size on the rear tyre, the unsprung weight would be a little less and the rear would have less inertia and more compliance. Or not... Nick |

I brought a 750T brand new (J340REL).
With the original Koni's, the wiring to the rear light rand on the inside of the mudguard, and the wheel on ended chaffing the wire. Guzzi replaced the shocks with a firmer set. Taking to another 750T owner, this chaffing happened to him as well. I ended re-routing the wire to the outside of the mudguard.

Yes, I noticed that too, but thought that maybe going to a 120/90 rear had reduced the clearance. In fact the bolts that hold the rear grab bar on need very shallow heads/nuts, or they touch the tyre too!
