Was talked into attending the mid winter racing this coming weekend at Hampton Downs, so got my mate to make up some rivets to reattach the ring gear to the pressure plate.

Blocked the crank at the front, lined up the timing marks, refitted the flywheel, fitted the pressure plate, fitted the 6 bolts......hello.....
Picture explains what I found wrong......

I know a bloke with a roller starter, he might let you borrow it. Ask nice he might even let you borrow the Triumph approved tool kit.

Tis a kind offer indeed, however 'The Bavarian Tractor" now has Bosch starting and Mr Lucas will not be required.

Hamilton Motorcycle Club put on a great event, very well run and the weather was perfect.
I met up with a fellow ADV rider Oscar who ran a smooth operation in Pit lane for the day...he must have been cold.
Team Bavaria fielded two bikes , the ever popular R90s and the less well known R90/6 touring version.
Sid was running a higher final drive and pulled away on the straights and both of us managed best lap times of 1:27, which was my best ever.
Our local KB group BFTP turned up and we had 5 BMWs outside 'the Eagles Nest" tent.
Entered in two classes , Posties/Classics and Clubmans B, so had 2 rounds of practice and 6 races...well would have had 6 but for the last one we swapped bikes and Sids super duper Lithium Iron red battery decided to die on the start line.....


There was a few cool bikes there too, a new Norton Commando, that he managed to lay down on the grass....
and his 1934 Royal Enfield V twin 1300 cc(?)

I was pretty knackered after 45 odd laps ( 120 KMS) of HD on the old Beamer. The last minute clutch works held up fine.
maybe Trust Me will have the old Triumph cobbled together for August....

Racing at HD on Sunday so doing my usual last minute prep.
Swapped out FD from 3.2 to 3.0 hoping I can see off the R90s on the straights....
Found a 'better' set of 36mm Dells in the shed, however my mate who made me the custom inlet manifolds also made me the nylon sleeves.
The custom ones are slightly loose on the inlet stubs. For test purposes I gave them a couple of turns of electrical tape but I would prefer something more fuel resistant any ideas on fuel resistant tape?
might go to Blackwoods in my lunch tomorrow and ask.
Swapped out the 136 mains for std R90s 155's.
The proof will be on Sunday to see if I can break 1.27 lap times.

Extremely poor quality vid showing bike actually idling and live ignition feedback. You can see the revs, the point of the curve and you can drag the curve around at the same time.
I altered it tonight to give a more stable idle with a bit more base advance.
Total advance is achieved at 4500, no particular reason but the bike seems to lack punch mid range.

R90s and R90 rematch.

Mods to R90s:
Engine raiser dog bones

Mods to R90
Less worn set of Ex Ducati 36mm Dells fitted with 155 mains.
Advance curve tweeked to give full advance at 4500 and a bit more advance at idle.
Leaded race fuel
new spark plugs ) change these every meet)
Bike now idles nicely when warmed up and only needs choke to start cold.

My target for the day was to keep ahead of the R90s and improve on my 1.27 lap times.
I decided to only run in Post Classic and let Max Headroom ride in Clubmans B
Max Headroom who owns a very nice tweeked R90s made his solo race debut and was going to ride both bikes back to back in different races.
This was going to be interesting.
Adrian set the tone of the day by my being unable to get past him.
I could get within several bike lengths but was never in a position to pass.
He managed a best time of 1m25 and I could not break the 1m27 barrier.

He had a few 'moment' when the Contis started to 'let go"
The BT45's were their usual solid selves.
Max took out the R90 which he had never ridden and got a respectable time of 1m34 and even got to pass some bikes.
Later in the day he rode the R90s, I don't know the times as yet.
He might chip in later but hes comments were along the lines of:
The floating Stainless Steel brakes of the R90s take a few moments to 'bite" over the cast iron on the R90.
The R90s was faster. ( 32:11 FD)
The R90 was slightly better at the low end. ( 33:110
At high speed the fairing was good on the R90s, and no head shaking at what was probably 190/200 kmph.
Max's best time on the R90 was 1m29.
Glad he's sticking to sidecars

Difference is probably the R90/s has bigger inlet ports with 38mm carbs and the R90 is the smaller ports with 36mm carbs.
Adrian had bought some Avons for next time.
I need bigger nads...

A great day was had by all.
I have decided not to build up a larger engine and develop the $250 one a bit more. Looking at the Dirk ideas of machining down the cylinders, putting some squish into the original R90 pistons, and fitting the R80GS D port heads maybe with a bit of port work by someone who knows what they are doing.

Had quite a few spectators asking about them, as BMW's are probably the cheapest entry to pre 76 classic racing here...but wire wheeled ones are getting harder to find for under 5K.
