The BSA Starfire I owned had a similar plate behind the clutch as standard (BSA Starfire was last C15). I remember assembling it without the plate. When I changed main bearings. When they failed they stripped the pinion timing cog. New main bearings were a BSA upgrade to ball bearing race one side and a special and expensive barrel roller race the other side. 50+ years ago now!

Hi Paul and Mitch, firstly I would like to thank you for all the amazing content being made, I am enjoying it very very much.
I would just like to say that I especially like some anecdotes from the past, maybe even an episode where you take us around your shop and Paul briefly goes through his work so far.
Thank you and be well, Mark

Ok, I'll be that guy. It's one serration on the chuck jaws. It goes faster if you use two parallels simultaneously. No fiddling required.

Many of us have all the tools Paul has, but he gets wayyyy more done because of his know-how. We're seeing a lifetime of learning and experience on display twice weekly. Thanks, Paul, for the motivation.

It was fun to hear you’re in touch with Steve Burns. I used to follow some of his projects with Performance Bikes magazine in the 80s/90s.

I get a big kick out of the fact that Paul expresses surprise upon achieving perfect fitment of a part which he scrupulously planned and artistically executed several machining processes.

My 71 Bonneville engine has a removeable panel to access the drive sprocket much like what your doing here Mr. Brodie. I guess they had savings in mind when they designed the cubs, nice modification whoever replaces the sprocket in the future will be very happy you spent the time to do this "Engine Mod" Thanks for sharing! Good work on the editing Mitch!

Hi Paul. I also did this modification, on my cub, but I put a bearing in, as well as a seal, for extra support for shaft. The plate needed an extra top-hat section to fit both.

Always interesting to hear you sorting out a solution in real time... Close enough.

After failing at pretty much everything in the garage today, I come here to see how it's supposed to be done 🙂

Thank you two for this channel, it’s perfect

It's going to be a well trick cub motor when you're done with it.Keep the vids coming.

Very nice Paul thought that big drill was a brave move with such a small purchase on the part. Lovin' it

Is it my friend Patrik, the Ghost-rider, who now has the 192 mph record? He has got far more than ONE screw loose !!

Steve Burns is a legend! Literally!! Funny how he gets introduced as a fellow Cub !

[retromechanicalengineer]

It's a good Mod Paul, similar to the B group engines. Steve Burns, there's a blast from the past. He was more famous for huge Suzuki drag racing bikes than Tiger Cubs in the 1980s. He was based in the UK then and was regularly featured in 'Performance Bikes' magazine.
Best wishes, Dean at Retromeccanica, Oxfordshire, UK.

Great videos! Steve burns was a legendary bike builder and mechanic! Good to hear he is still around!

Great job Paul, Your Tiger Cub is just like my Triumph T120 now!

[johnpublic]

Hi paul: if you reference diamond chain or machinery handbook. They say do not use a even numbered tooth drive sprocket. Because of wear. I checked several manufacturers honda KTM. they use uneven tooth drive sprockets. Also if you have a choice between a light chain and a heavy one in the same size chain use the light one. It's easier on the sprockets.
Love you mods and planning you do. Very inspirational

[MotoDeSoto]

Excellent modification. Great idea.
Sometimes a piece of wood under one of your clamps will damp out vibration.
Nice video. Keep up the good work!
