He won't be too hard to keep up with........No chain.
Paulr, that looks seriously good! You have a shot of the other side?
Quetions, questions. 
Is the pipe a custom made job? What's the gear lever off? Looks to be a lot of travel in the back end.

My mate Marc will be chasing him on his XL250 too....

Header by Pete Lawson and homemade mega; sounds great but may not please the Conondale officials in August?
Gear lever after market for XL's (fine spline and either an F4, FG4 or FB4 - cannot remember).
Must admit have not tried the S&W's; ran Mulhollands last year suffering serious coil bound issues on jumps [arse to fat!]

Back onto that XL of Paulr's,
I notice you've put the later model (or 350) right hand engine sidecase on it. I need to replace mine at some point due to the bottom edges being eaten away (whatever happened there?) I could have gotten that type of case but thought it may not have fitted. With the different angle on the tacho drive..does this still work with the gear inside, or have you taken that out?
Love your frame sidecovers BTW. 

Nice to see all the bikes, it's good for the imagination.

[paulr]

MX?, a good observation!
I had an annoying problem of breaking kick-starter shafts (the original shaft splines were well mutilated followed by kickstarter itself causing additional problems).
Obtaining a replacement kick-starter shaft for the KO250 was near impossible whereas the shorter (by 10mm) later model ('74) shaft is readily available over the counter.  By shear luck the later casing fits the motor 100%, even down to the speedo drive (which I've removed).
The only mod I had to do was grind some of the rear brake pedal / bracket away so as to clear the kick-starter on the downward stoke.
Cheers

hello paulr,
               speedo drive?if you mean tacho drive then I hope you fitted something to get the oil from the case to the galleries when you removed it.

I found there was a difference somewhere in the two models,one had a restrictor jet inside the tacho drive shaft and one did not?

MX?  good to see the progress,I won't get to race you due to retirement but my bike should have a new owner soon and it will be back out there roosting

Retiring? I didn't think you racers ever retired.....

[paulr]

Gorby, yeah, you are correct as speedo drive should have read tacho drive.  All I removed was the drive gear with shaft and internal oil passage still in place.  I could not find any differnece between the oil passages of the two casings and with a full season under the belt, it continues to run well.
All round, a great little bike!
