Title: Rotary Bikes at Rotorstock III 2006
Post by: Norton on January 13, 2006, 12:53:00 AM
It looks like we may have this beauty at Rotorstock III.
It was built in 1989 by a guy from St Neots. It is a replica of the 1989 air cooled Norton race bike but it was built for the road and is road legal !!! Power output is about 130 bhp. It now resides in Lincoln.
See picture below. Bike Magazine got non other than works rider Trevor Nation to road test it (thats Trevor sitting on the bike).

\'a man cresh\'... good description  :D
I had hoped (and have previously mentioned on here) that a friend might be bringing a pre-JPS liveried factory race bike (like the one pictured) along. The bike is undergoing a complete re-build and unfortuately it doesnt look like its going to be done in time, it should be at RS4 though. So, everything crossed for the JPS replica.

Hi Derek

Just wanted to know if you guys will be attending RSIII so that we can allocate an area to you.

If you are attending, how many do you think will be coming along.

Hope you can all make it.

regards

Hiya Lisa
I think i was a bit too optimistic last year, dont you? 5 bikes in 12 car parking spaces!!  Me and Geoff will be there as usual (possibly Sunday & Monday / maybe just Monday.. will have to check with Geoff) and hopefully Mark with the JPS replica (ive sent him a reminder). One or two other \'maybes\'. I dont hold out much hope for a big turnout (i despair!!). Much of the problem is that the Rotary (Motorcycle) Owners Club attend a Classic Bikes event at Stanford Hall on the Sunday.
Do i need to send a cheque to reserve the space? Will we be in the same place? Looking forward to it!! See you all soon.

Hi Norton

Thanks

Clive has advised that you do not need to make payment for the Bikes, however we are raising monies for Cancer Research so you may want to make a donation at RS.

Not sure about the aloocation of the area.  We are currently looking at this when all clubs etc have regsitered.

Look forward to seeing you there.

regards

You \'hope\' to be there Ian?  :xconfused you move heaven & earth m8!!
Yes, we will be there Monday, still not sure about Sunday (still waiting for a decision from my track rival). I see that there is a lot more RWYB time on Sunday.

ok, so the Classic Bikes event at Stanford Hall has been cancelled at the last moment due to waterlogged grounds... so... we MIGHT have a few bikes at RS after all.
I wonder how wet the camping field is at Shakespeare Raceway.

Rotorstock III… we got our asses whipped reeeal good!! Malcolm Stanley, ex- Derbyshire police Norton rotary mechanic and experienced bike racer, brought his red ‘Earlystocks’ Norton Interpol 2 race bike along to Rotorstock for his first ever venture onto a Drag Strip. Im not sure how many runs he did, it must have been around eight. On his penultimate run (against me) we were side by side about two thirds of the way down the track when Malcolm unexpectedly pulled out a lead of a few bike lengths to finish in 12.1 seconds, beating my best of 12.3. On his final run (against Geoff) he repeated his ‘top end of the track blitz’ to set an amazing time of 11.7 beating Geoffs best ever run of 11.9, all this without the aid of an ejector exhaust!!! When pressed on what his secret was, it would appear that its all down to revs, Malcolm has modified the bike to rev higher than the standard 9000rpm, I think a figure of 11,750 was mentioned. He reports a loss of bottom end torque but is able to hold each gear longer and wring a few more bhp out at the top end. Congratulations to Malcolm. Red faces for me and Geoff (sunburn, honest).
And we still haven’t managed to get a Suzuki RE5 to Rotorstock… pleeease, can somebody bring one along to put on display next year.

You\'ll have to pursuade Tim to resurect some of his old two wheeled rotary machines.

The early red silver & blue race bike belongs to Malcolm who brought the Plod bike and the suprisingly quick red bike this year, so that should be there next year.
Sadly a no-show from Mark and the JPS replica, dunno why yet.


 :Thumbs-up Nice pics Ian.

Not excellent, could have been a lot better, but was sitting half way up the stand. Get me a better position and I\'ll do better. ;)

I asked Malcolm how he did it, this was his reply...

Ive just got hold of Malcolms figures from his final run...

   60ft-       2.080
   330ft-      5.075
   1/8mph-   95.97
   1/8sec-    7.589
   990ft-      9.737
   1/4MPH-   116.51
   1/4SEC-   11.72627

Looking at that i think theres more to come, the 60ft could be better and the Terminal Speed isnt as high as i expected... watch this space.

Seems pretty quick considering how old the technology is in those Norton rotary bikes. Do you know where and when Malcolm is likely to be performing Derek?
Title: Rotary Bikes at Rotorstock III 2006
Post by: Norton on June 16, 2006, 11:49:01 PM
Unfortunately hes had to give up the circuit racing so i think we will have to wait until Rotorstock IV. By then he should have the 1987/88 \'ex-works\' blue/silver/red bike up and running which should be a whole lot quicker again so the red bike may lie idle... hmm.. maybe he will lend it to me  :D
