I did plenty of track days on my TRX all across the UK and loved them all and how the bike performed.

It put out about 90bhp with FCRs and a pipe, and had some minor suspension tuning so nothing too wild.

There was always some guy on a GSZXCBRRRR1000 who whizzed past on the straight, but thats not the point. I was there to have a good day, get the most out the bike and go as quick as I could to the max of my ability, not to race.

If you want to always be "winning" like Trump, spend £10k on a superbike and hope your skill level matches it.

Spot on, that! =D>

the idea is ....NOT changing from the TRX.....The modern bikes I race against are ridden by old amateurs like myself.....true they damn fast on the straight and have better dynamics, but as long as i keep reasonably close on lap times I am happy.
The true opposition I race against are the GSXR750 and modern 650s etc
I have beaten the latest model ERs that are well tuned, but there is nothing in the lap times. Just get to turn 1 first.......and don't F-up along the line.
Everyone loves my bike, because it's the only one racing in the country and sounds so damn awesome.

True...suspension is always challenging.....I do everything myself normally and have made some mistakes...but learning is half the fun.
Carburation still not sorted, but it runs OK.

Sending my rear shock shim stack away to have the shim stack upgraded for my weight after my next track day.

They do sound fantastic. I love my bike the way it is with the triple engine, and it does sound savage, but I dont think its sounds as good as the lump it replaced. theres something about it, perhaps its the fact that its a big twin that doesnt rev very high so you can really hear the pulses through the exhaust.

couple of flyby videos from back in the day(6 years ago!) - I am on the black 900, and my father in law is on the red one with FCRs

So...yesterday I swung my wobbly 55yr old legs over the TRX for the first time in 4 months. "Testing at the track" they call it.
It was actually a dangerous affair as I have done nothing but office work for 4 straight months and have zero racing fitness, or any form of fitness at all. I did however manage a few good laps particularly during my second session.
But due to the lack of fitness, twice I strayed off the racing line, once having a massive front wheel slide on the dirty part of a corner where a car had dumped some soil and stones on the track and the other just loss of concentration and not making a fast corner and having a long farming excursion.

Getting back to the facts:
First session I went out and in and out and in, to adjust the rebound on the front end after having fitted the Racetech fork springs and a thinner oil.
Happy-ish with the front, It showed the rear end to be the culprit particularly during shifting my weight on the bike and gear changes at speed whilst at a big lean angle.

Session two, I reduced the high and low speed compression quite a bit at the rear, came in once to speed up the rebound up front by two clicks and then had quite a good session.
Came in and saw the rear tyre was wearing better than I have seen in a long time and the bike was much better balanced between the front and the rear.

Session three, no changes, I went out and struggled with consistency and pace....came in and saw the rear was wearing in an undesirable manner. Well this could only be the rise in temp from session 2 to 3.

We skipped a session and now my muscles was cooling down and I was getting stiff everywhere. (well not everywhere, but I am sure you understand)
Nearly did not do session 4, but my curiosity dictated another venture out. Slightly reduced tyre pressure at the rear and the tyre started to clean up.

It was the longest slowest load up I have done...just knackered.

Lessons learnt.....don't be lazy, change the pressure during the day as needed. Get fitter somehow.

PS, the club is hosting a race day in 3 weeks time. We don't know if there will be bike racing, seeing they have to get the go-ahead from a hospital that will take trauma patients in this Covid times.
Believe me you don't want to go to a state hospital in Africa, particularly now. Apparently, the private hospitals might not necessarily give the club the go-ahead.
I WANT TO RACE!

yes...muscles knew all about it. Had another track session today...only went out three times and rode well, but still riding unfit.
