Sometimes you have to say WTF, right? Tonight I bought a 1968 T100 C for what I like to think was a good deal. I don't know what going to happen to it. It has a lot of goofy things about it as well as some really cool stuff. Per the Craigslist ad:

"Matching engine and frame numbers, new Dunlop Gold Seal tires and tubes. Updated with Boyer Ignition. Chrome Oil Tank and Side Cover. Needs very little TLC... leaks sealed up, fluids changed. Has high pipes with aftermarket mufflers. Have correct mufflers, but need a little work and rechromed. Also have correct throttle and Gran Tourizmo grips, but not perfect."

I shot these pics as the sun was going down but I promise to get better ones up soon.

yeah, please leave it the way it is. that sickle is sweet. Please don't hard tail it and lay a $500 gay paint job on it. Just a great bike the way it is.

Thanks guys. No plans to hard tail it. The only immediate plans are replacing the rubber on the foot pegs/kicker, new tank pads (dry rot) and putting the correct tank badges on. I'll get more pics up tomorrow.

This is my first vintage bike so I'm stoked to work on it. I already plan on getting the "English 101" dvd but any other pointers or suggestions would be appreciated.

Took it out for it's first maiden voyage it traffic today and all I can say is... what a dog.

Really riding it in traffic has revealed more flat spots in the throttle and tons of sputtering. Think biplane at the beginning of Van Halen's "Panama" video and you've got it. It topped out at 50mph WOT.

Tomorrow I'll replace the air filter, plugs and rebuild the carb. It's been sitting since January so it's kind of a mess. The carb is leaking from the body gasket and there's sediment in the fuel line past the filter. At first I thought the cheap filters were letting stuff though but now after riding it I'm thinking the stuff is coming the other way out of the carb itself. I'm taking it over to a local vintage Brit bike guy and have him give it a look over and to do list.

Tonight was the first night ride. The neutral light works; in 1st, 2nd, 3rd and 4th. So does the brake light; always. The same can't be said for the lights on the speedo. The clutch works great after a slight adjustment on the lever. Seriously. No regrets. This is a fun bike to ride and corners great! Plus it's really comfortable. I can't wait to share it's progress with everyone.

Cool bike Brett, try to take some less blurry pics of her before you start the redo.

Here's the latest. I swapped out the plugs and man, did that help a lot. It was crazy how just doing that helped it. It was running strong with no sputtering however I had to keep feathering the throttle to keep an idle. I rode it over to my mechanic's and we tried dialing it in. We got it idling albeit a little high. There was a slight leak coming from the banjo fitting on the carb. Here's where it got weird. We cranked the air/fuel mixture all the way shut (no fuel) and it ran fine. That told us there was something wrong inside the carb itself.

Friday I took just to see if it would pass emissions. It didn't but only on the sitting idle part. Friday night I rebuilt the carb. For starters it was missing the inner sleeve for the spring on the air valve. Then it had the wrong clip on the needle along with a twisted piece of wire as an attempt to keep it centered. Clean and put back together with fresh parts and gaskets back on the bike it went.

Long story short it ran about the same as before including with mixture shut off. I delivered it to my mechanic's and he noticed a number of things wrong including:

Float bowl a little high.
Some warpage from someone over-tightening the bowl.
Some warpage from someone over-tightening the banjo bolt.
Wrong jet size (too big)
Someone had increased the size of the pilot jet pressed into the body.

All this explains why it was running so rich and with the fuel off.

Fortunately the 1968 carb bodies were converted over from 2-stroke off-rode carbs so there's a spot to add another jet in the circuit. The plan's to add a new jet and close out the old circuit, fix the bowl, decrease the jet size and file down the carb halves and banjo bolt fix the warpage.

I'm supposed to pick it up tomorrow so I'll let you know how it goes.

Here are some overdue pics I snapped off this morning. The bike is currently sans carb since it's out being worked on. I haven't even had a chance to give it a proper cleaning yet but hey, It will make the next batch of shots that much more impressive.

Original tail light has a small crack on the underside but is in good shape overall.

Chain oiler works great and will probably have to be dialed down a bit.

Newly rebuilt Amal concentric carb awaiting to be installed. Given the amount of parts swapped out it's heavy on the "new" part.

Great looking bike! I agree with the others, I wouldn't change the look at all. Bought a 69 Bonneville that I will be picking up in a month. Can't wait. I bought the English 101 DVD and I think it is well done. They now have an English 102 out that i plan on purchasing as well.

i think you've got yourself a real winner here.

super stoked for you and the progress on the bike to get it running.

+1 on the DVD's. Very helpful and easy to follow. Grab a parts book as well from British Cycle Supply ( BCS#216-990832). It has the part codes for every part, nut, bolt, washer etc.. very handy when rebuilding. They also offer a DVD with the parts books, owners manuals and other assorted tid bits for almost every Triumph from the late 30's up to mid 80's (not sure of the code) And no i'm not a BCS rep i just love Trumps. Pick up these 2 beauties for a song this year. The Tiger is going to get a hardtail and gay $500.00 paint job and the Daytona is going to get a complete restoration.

Hey guys, have I got a story for you.

So this morning I went out and pulled the carb, something I've gotten really good at lately. For grins I dropped the needle. Then reset the mixture/idle to spec and guess what? Rocked it! Took it out for a spin, came back, shut it down and it fired right right back up. Did a little tweaking between the idle vs. mixture and when it sounded good I grabbed my shit any beat tracks to the testing station.

On the way there I pulled over and shut off the engine just to push my luck. Fired right up and I actually played with the idle a little more.

I got to the testing center and waited in line in the 100+ PHX heat with the engine off but would start it to move up in line. When I got inside they took my retest form scanned it and asked if I was from a dealership. "No?" They then told me the bike had already been tested and passed. As they gave me the certificate of compliance the woman asked "Don't you remember bringing it in?" Guess not.

I can say this, apparently it pays to be courteous and friendly to the manager who was on duty the last time I failed. I immediately went to the DMV and the bike is now like M.C. Hammer - Too Legit Too Quit.

Thanks everyone for your tips and suggestions. It takes a village. The bike's going to get it's douching this weekend so stand by for more pics.

Awesome deal congrats on figureing it out ...I wasn't sure if the timing was it but seeing you said you messed with the timing and I know the hot won't start thing related to that sort of scenario I wanted to throw it out there ....carb is just as easy of a fix though good job ...:clap for you:

Epilogue: Yesterday my girlfriend brought her MSF receipt into the DMV to get her permit and amongst the shuffle they ended giving her a full endorsement even though she never finished the class! Guess it was a lucky day for both of us.
