I've recently had my entry confirmed for this year's Pre-TT Classic event held on the Billown Course near Castletown. I shall be riding my Breganze 840 twin in the 1100cc race for pre-72 bikes and a Zane 650 in the Junior Superbike class. If anyone is over on the island for those dates, they are welcome to come and hang out in the paddock or better still give us a hand.
 
Good Progress has been made with the race prep on the 840, even fired it up today, although it was a little reticent at first, just to make sure everything seems to be working okay. Rode it up and down the industrial estate a couple of times, and it goes, stops and selects at least 4 gears. However, one of the new belly pan brackets broke in even that short space of time so will have to beef them up a bit.
Plan to start work on the 650 next week, should be just about enough time to get it ready.

That doesn't look at all easy to mount without it moving and work hardening. What's the hose exiting the back of the seat, engine breather? It's a serious-looking weapon.
 
I'm guessing those belly pan mounting brackets were aluminium if they only lasted a few minutes. You'd be better off with mild steel for the brackets. It won't look as nice as aluminium or stainless, but it'll last longer before cracking. It might even get you through a whole race. I'd be taking some spare brackets to the track if I were you.

It could pay to have some safety wires to stop it going under the bike in case they all break. My SF racer would have had them all broken in pretty short time. Vibration for one, and wind pressure at 200kmh need sturdy brackets. I made a tray to go above the exhaust, screwed to the drain plate and neutral switch cover.
 
If you use that pan, I'd use the old generator mounting holes on the right side, crankcase M6es on the left side - and beef up the brackets for sure. Even add in rubber silent blocks.
 
Saw a recent bike crash video on Utube where a front guard suddenly broke and pivoted under the front wheel becoming like a skid like on snowmobiles. Crazy way to go down. Definitely safety wire it.
 
I am going over on the 21st and will be spectating, You have no idea Andy, how close I came to buying that bike, so you had better go well on it, twas/is a very well sorted bike, by very capable people, who just like me, are sidecar fans.

I normally use steel straps on my other bikes but my mechanic friend thought he would try these, not that i was convinced they would be good enough. I shall revert to steel and, as suggested lock wire the pan as well. Consideration was given to trying to fit something between the engine and exhaust, but it was going to be a difficult fabrication as the gaps in places are pretty tight.
Unfortunately, unlike the 500, there are no bottom frame rails to secure the pan, nor a convenient front engine mount like there is on the 650/668 models. However, I’m sure we will get it sorted.

Bring cash or your cheque book Clem and you never know it could still happen...

Secure it with cable ties or a big O-ring, but as you say you will get it sorted…..
 
Bit of a mixed bag mood-wise today for first qualifying session.
Most of my kit failed scrutineering the day before for not having the latest CE marking, so I am now several hundred pounds lighter having had to buy yet another new set of leathers, boots and chest protector. At least my helmet passed but with the new regs it’s got less than a year of life left, and I have barely worn it because of covid interruptions.
The 840 had a couple of issues picked up at scrutineering, a pin in one of the front calipers wasn’t seated properly so one pad wasn’t moving. That was easily resolved. On full left lock the lock stop wasn’t doing it’s job as well as it should, but they let that go on the basis it would be reinspected tomorrow. I had also overlooked they don’t like Monza type fuel caps anymore and require tanks to be vented via a tube and none return valve. They also let that go for this evening on the basis the cap was locked shut by a spring clip and it would be modified before the next qualifying session tomorrow.
By the time the bike got the all clear for qualifying, and I had more-or-less given up on getting out in the session, it became a bit of a rush to get ready as the 1100 session was out early doors. The bike then decided to be a total bitch to start, even with liberal amounts of easy start squirted down the inlets. It eventually decided to cough and splutter and show some signs of life, but not enough to keep going on more than one cylinder. A casual observer then remarked, it looks like one of the throttle cables is coming out, hence the running on only one cylinder. A bit of tape around the two cables solved that issue just in time to get the bike started and out of the gate and onto the dummy grid.
Given it’s nearly 40 years since I raced a bike around the Billown Circuit, I was on an unfamiliar bike, with the gear change on the wrong side, and the roads still damp in some dodgy places, I took it very steady to start with. I had a bit of difficulty hooking up the gears, and was having to slip the clutch a fair bit to get around Ballabeg hairpin, at crossfourways and the Douglas Road corner. However, after a couple of laps I started to feel a little bit more comfortable and began to open her up a bit. It’s certainly got a bit of stomp in it. unfortunately on about my fifth lap, going into Douglas Road corner my number was being shown and I was directed off the course. I toured back to the paddock through the back streets of Castletown wondering what the issue was, as looking around I couldn’t see anything falling off etc. Back at the paddock, from a cursory look around the bike I could see there were oil splatters on the exhaust, and it was confirmed by the scrutineers that I had been black flagged for excessive smoke. It looks like one or more of the right hand oil seals has failed again, so that’s a bummer. 😪
So, i’ll just have to make do with the (supposedly more unreliable) 668.
A report on first qualifying with the 668 to follow.
