Wow, time's running out. 2 weeks until the MWVTA opener in SanYo. Guess I'd better get busy on this pile.

I removed the carb this morning, opened 'er up, and found....a bit of water in the bowl, and crud around the needle jet -




Hmm, maybe I should look at this carb more often than once every 5 years. I checked the main jet size - 76. Yeeeah, a bit lean. I guess that when Lineaway jetted it for 10,000ft 7 years ago, the engine was already getting weak. I pulled out the carb for my personal TY since it was already cleaned and had a fresh gasket kit installed, checked the main jet - 84, much better since the OE jetting was 86. Installed the carb, and WOW!!!!! MUCH better!!!! She runs very, VERY well now.

MWVTA, here we come!!!

Opening round of the 2014 Mountain West Vintage Trials Association season as told by The League -

The weekend started off well. I dragged old OJ off the porch to act as a work mule this weekend -



Hmmm, I had not started, washed, nor even paid any attention to the old crock since Roswell last November. Some Haystack mud still clinged to the skidplate -




Loading up, rarin' to go!!!




Arrive, do some cleanup on the loop and sections, hang out with old friends, and...

Campfire!!!




Got up Saturday morning to discover a flat tire on the Team bike.

I had noticed it the night before, and texted Hammer to save the day. He came through with a new tube, installed right before the horn sounded for Saturday's Trial. Not a good way to start the day -




Stupid cheap-assed Chen Shin tubes really ought to last more than 5 years anyway. I'm gonna fire off an angry e-mail....




The Team bike did get a new plate just for this season, courtesy of The Hammer -



The League. 'Nuff said!

Signup, with an old twist -



Yup, Hammer sportin' da dreads!!

Day One. Some Carnage.


We are not even to our first section when this happens to Yosemite's TY -






Yowza! A quickie fix, and we are on our way to our first section! Go get 'em!!!




Oh, this is gonna be a long day!!!



Some random shots of day one -

Boss Lady, who drew the short straw to ride with us Goofballs -








Yosemite -








Hammer -








Yours Truly -








Ah, young love between TY80's -




Hey baby! Remember when we did this on the way to Sturgis on our first TY80?






Day one ended with a killer feed put on by Old Geezer and his teenage bride , with the storms moving in. Wind, rain, hail, sleet, locusts, plague, et al came in Saturday evening. After the worst part had moved on, it was an early night for the campfire kids.


Sunday. More Carnage!!

The wind had blown hard all night, but at least it rained too! We're not afraid, it's time to go ride!!

Oh wait, a flat on Yosemite's bike, and the pipe had come adrift on the Team TY!!

The Fred Flintstone tools did not work on the pipe -






So Yosemite Matt went back to camp for some slime and tools. I did not get a shot of Yosemite sliming the rear tire of his TY, but did get a shot of Hammer fixing the Team TY -



Gonna be a long day....

We had an interloper join in on the TY festivities. JB Brown -






Hammer -








Yosemite -






Boss Lady -









Hey Yosemite! How well does that bike run again? -






We fought rain, hail, and snow all day long. This loomed on the horizon most of the day -





But we don't care, for we are...

The League!!









At the end of the day, I had a really bad get-off on the loop to section 8. Over the bars, bashed in the fuel tank, and broke a fin off of the new cylinder head -







The nasty weather continued on the way home, but at least it was a tail wind!!






Battered, bruised, and scarred, The League will be back!




More to come...

Spec is 85cc's, we have been running 75cc's with Bel-Ray 30w fork oil and we still blow a couple of sets of seal per year. Specs here -

Short answer is the engine is awesome! Pulls hard up hills and will do 3rd gear wheelies as far as you please. It's still runs rich right off idle even with the needle all the way down. I need to go to Yamaha and see if leaner needles are available, if not it will be time for some carb/timing tickleing.

What air filter are you running? Not sure if there are any cheaper routes than a 20 dollar stock replacement.

To the blown fork seals you and the others in the pic's are in another weight class, with a Bultaco that wouldn't happen ;)

To the carb I would look up smaller main and idle jets, the use of different needles will not satisfy you, you might switch to other diameter but then the idle jet has to be changed too.

Another tipp try a colder plug

The air filter we are running is the replacement one from B&J racing. I did however, modify the air inlet on the stock airbox -






That was done before the engine overhaul, in an effort to try to get the old girl running well enough to compete on. With the new top end, it really honks now!

Bultaco?? Why would we want to compete on that? Those things are huge!!

This brings back some memories, my first bike was a TY80 Whitehawk. I will look for some photos of it.

Neutral is on the bottom. It's fine!
