Triumph Tiger Cub [Bantam Cub] 10 Another road test with revised carb and timing settings.

- I re checked the ignition timing and decided I could back that off by a couple of degrees and checked the fuel flow to the main jet, which was good, but the main changes made were in the carb settings, where I raised the needle to the fourth of five grooves, and, having checked the Trials Cub settings, went up from the supposedly correct 90 size main jet to a whopping 140, as in the trials machine which runs and performs so well with an identical engine and carb.
As can be seen here - what a difference it made!

Well done Paul, great work. As regards the key falling out, my old 3TA used to do that too. I used a croc clip and string to stop me losing it. Placing in your pocket seems safer.😂. Thanks Paul
G'day Paul, just needed fuel, traveled well that time, road rather wet, cheers mate, Neil 🤠.
Finding the key was a major win! Good you felt it hit your foot! Amazing find! Your guardian angel wears a hard hat too!👍
Sounds a heap better than it did before. I had a Bantam Cub or T20S/C (looked like yours but said T20S/C on the V5) as my first bike, would love to find it again. Oh and I kept my key tied to the front brake cable with a bit of string. Lock could be operated with any flat object so wasn't much of a security risk🤣
Saw the key working loose in the ignition switch , having the red key fob helped, good find
I noticed that. 5.15 mins in, just before the s bend.
I thought a normal flathead screwdriver would stand in for a Cub key, & I guess you always have one of those with you..
The most fun cub test ride on the road so far. By it pulls well! This is the top gear ratio that your noisy one could be pulling. Great that the front brake is bedding in, and with the touch of smoke lessening perhaps the rings are settling in. I think these little TriBSAs are really hard to beat.
A real stroke of luck with the key, I opted for a very visible fob after my Arrow did the same on it's first outing. What a transformation indeed, well done that man.
Thank you!
It's more like the ISDT with river fords and mountainous terrain, and that's just going for a test ride! I'll bet it's lovely when the sun comes out though. The Cubs going all kinds of better with those adjustments Paul.
Thank you!
You have transformed it. The Cub Whisperer strikes again!!
Thanks!
Lost my keys near bridport on my f1100. Realised they weren’t in the ignition when I was about five miles out of town on the dc westward. Stopped turned round and retraced my rout to the petrol station and basically rode in the gutter all the way back to the point I’d made the discovery. At 70 plus at some points I was thinking they could have literally gone anywhere and then realised when I’d retraced the whole route that I had a locking fuel cap!! Brimmed it at bridport but I’ve just wasted a load trundling slowly along on second. I was walking round the bike peering at the fuel cap and wondering if I had the tools to break it open, when I spotted the keys, in front of the tank caught up on the inside of the fairing on brackets and wires and that. What a relief. Ever after I clipped them on the bike with a dog lead clip round the mirror stalk. But they never bounced out again
The little cub sounds great. I thought I was the only one that had lost a key like that, luckily I found mine also 😊
That Bantam Cub is turning into a nice bike. Well done sir.
Thanks 👍
Oh drool! I have a Super Cub ( more Bantam than the Bantam Cub.) Had it new in 67. Still in running order but it spews oil out, more like a dead loss system.does. Was hoping to strip it down this winter but its been too cold for me to start it. Will watch Paul's other vids with interest.
You were very lucky to find the key, and to have nothing coming in those narrow mucky sections.
The last time I lost my bike keys was on the M1 near Barnsley. Got run over by and HGV, has to do some very quick sums to make sure I had enough fuel to get to York.
Those Tiger Cubs are really super little bikes.
Shows what a bit of knowledge and experience can do. Sounded better from the start, as far as I could tell.
Thanks - it was a complete transformation!
Good to see it coming together and sounding a lot happier with life. Goes to show those small incremental changes do make a big difference. Well done again 👍
Thank you!
Nice when stuff works out! I’m looking forward to your jet video. Cheers
Ahh the spade Triumph key, always jumping out! Back in the day I used to have a bit of string looped through the key, then loop it around handlebars or cables and back to ignition switch. Walla! when you stopped you could just unloop the string and put the key in your pocket. Mind you anyone could turn it on with a screwdriver. Top bit of kit hey!
I was expecting that key to fall out but missed it actually happen although it can be seen in the video, it was lucky that you spotted it was gone, lucky you noticed something hit your boot and you were lucky to find it and it was lucky not to get run over and bent up by a car !
You can't really get more lucky !
Were happy to. Thanks.
Thanks again, Herman!
Well Paul it sounded much better right from the get go 👍👍👍
Thanks!
I thought keyless ignition was a modern invention 😂
Mm, it could be the silencers you have on that bike but your engine still sounds advanced to me, especially when accelerating out of corners at relatively low RPM and throttle open. And this is really cold weather by the look of it. I reckon you might still make it ‘ping’ in the summer on a hot day riding a similar route.
The timing is definitely spot on to a couple of degrees late now. When there are no signs of pinking while pulling up that steep lane, things are usually good. What is this 'Summer' and 'Hot weather' of which you speak?
@ sorry, I’m watching from Queensland.
Hi Paul, great video as usual. Would you ever consider performing a "Plug Chop" whilst pulling up the hills to see what the mixture is at the plug?
Hi- not really, I can usually feel if the throttle response and performance are right, and pinking is easy to hear. I will often take a plug out after a run, just to see if the colour is about right, though.
All that water and mud - you can almost hear the owner crying!
No salt though, hey!
I once lost a key, never found it, had to use a screwdriver after that!!!!!!!!!!!!!!!!
By the way, that camera improves all the videos: it might pay you to give a shout out to the manufacturer, and share the make/model of a quite good piece of kit
Thanks - already done!

It is one thing to lose your keys it's something else not to find them. I lost my house keys and my bike lock keys off my psac 15 when the key just vibrated out😢
Hi Paul does the cub engine fit the bantam frame without cutting and welding?? Looks nice.
Hi - the Bantam frames' engine mountings were altered to accept the Cub engines at the factory.
@paulhenshaw4514 didn't know that .thanks
Much more sprightly, what does the plug look like now?
Funnily enough, the plug looked a bit on the dark side after that failed test ride, but then we were going downhill and never went over half throttle on our return leg. After today's ride with the 140 main jet, the plug was black around the edges, but dark brown at the insulator, pretty much the same as the one in the Trials Cub replica.
60 from a classic 200, that'll do for me.😊 Question, what's the difference, pros and cons of the Cub frame to Bantam frame ? Cheers!
There's not a lot of difference really, but Bantam framed Cubs are among the rarer examples and used the very last engines, which were among the best to have.
