Mike, good show! ....... With the MAP pistons and VP C-12 you should be able to make more power on less total ignition timing For instance the RVP of LL100 is about 5.8, that much lower than pump or race gas. I can't find the 90c evaporation for Avgas ..This importance of this stuff for getting all there is from gas is mentioned in the Mark Parker's thread and elsewhere here in this forum. Just suggestions of course...

you need to get off your ass and put up pictures of your whole machine

don't you have a teenager around somewhere? they're very useful shortcuts for ephemeral technology.

i have lots of teenagers so when you send me something we can put it up

Wow! Guilt me already whydoncha? Teenagers you say? Sorry, my friend, I started early. They are all 30 somethings now. And I decided to not go down that road on my second go round!

Now my turn. Where's that track bike we've heard about? We need to gang up on those pesky BSA's!

lol

my youngest just turned 13. i have four teenagers in the house right now. i come home and there is no food. at all. they just inhale it and leave all the dishes strewn around the house.

food didn't use to be a problem when i was the only vegetarian, because nobody else would eat the stuff that i ate. but my oldest daughter is a vegan and she eats all the vegetables before i get home.

the track bike is in boxes. all there, everything except headbolts and pushrods, and may some other stuff i'll discover when i put it together.

Roebling Road is a relatively short trip from here, about 5 hours. Got there Thursday after dark and decided to wait to set up pit till morning. Fri AM was spent doing just that, registration, tech, Finally got on the track for practice early afternoon. Was able to get in both 20 minute practices, re-learn the track, and get used to the new motor work. Had it jetted for Asheville, a little fat there, wound up a little leaner than I'd have liked at sea level, but it was running great. It was turning right at 7000 at the end of the long straight so I was happy with the gearing for this track. Speaking of the track, It's had a couple bad spots in the past, and I found a couple more this time. One in particular had me thinking I'd be doing some off roading but managed to hang on ok. Decided to not use that particular line... On Saturday, had another good practice in the morning and won the classic 60s 650 race by about 20 seconds but did have some fun with the Manx guys who started in the rows in front of me. Raced in BEARS later, too. Wound up at the back of that bunch but had a good race with John Snead for last place. Did post my best lap time of the weekend in that race, though. About 1.5 seconds better than last year's best. I'd have thought It would have been better but I'm feeling like I'm not getting the best from my tires this year. The front doesn't feel planted in the turns. They are just street compound so maybe time for race tires. And I don't think 69 Triumphs were known for sophisticated suspensions either. If anyone has any tips, I'm all ears!
Sunday, morning practice and afternoon race, again a win. Mostly because Jake Hall wasn't there. He and I generally have a good race when we're on the track together.
All in all, a good weekend, the bike ran great, got some hardware and points, weather was beautiful, and saw some great racing. Next up, Carolina Motorsports Park in a month.

Mike, good show! So to get it straight, you are running MAP pistons and different cam timing than last year?

@Mike, give kommando a PM regarding front forks, he made new guts for my 71 forks , now have high speed damping and low speed, with options to change shims for Hi speed , and a needle valve screw for low speed, RHS fork all comp, LHS all rebound, works great. older forks have only one damping option which usually works fine at low speed bumps ( undulations) but effectively locks up for high speed bumps ( potholes, kerbs, bricks, step changes in surface), the new hi speed circuit is effectively a pop valve controlled by spring shims.

Tony, Yes, MAP 10.5-1 pistons this year but with last year's cam timing. 101.5 intake and 104 exhaust. I like a conservative approach when I change things. Like 1 thing at a time. I think I'd like to change it up just to try - maybe 103 or 4 intake and 106 or so exhaust. I've got enough cam gears, hopefully find something close.

Thanks, Gavin for the tip. The front end would do basically as you said when crossing the bad parts of the track - kind of lock up and skip from one ripple to the next. A bit unnerving. I have considered going to a 71 style front fork, but if something can be done with the old steel slider setup I'd be interested.

Mike I do know that Guzzi guys adapt the adjustable inner dampener from Honda 600 CBR to fit 35 MM forks.....This might work on you steel slider front end...I will ask for the details but it's not a straight bolt in job...I assume you have to use a vintage Triumph front end?

Not necessarily a Triumph front, if I could get my hands on one, I could use a Norton fork. From what I understand, they will more readily accept a Showa cartridge or something similar.

10.4.3a - Forks and rear shocks must be of the period. Ceriani forks are prohibited.

I wonder if that set of Betors in my garage would be acceptable????

The Honda fork cartridges are mostly likely Showa..Not all Showa forks use emulators or cartridge dampeners from what i know. A friend has a 72 Triumph with Betor forks and a fabricated brake anchor for the 72 front brake..He said it was a noticeable improvement...The Betor fork yokes on his have more offset than a stock Triumph yokes, it will make the bike turn in faster,.... that may or may not be desirable..
I got a text from my friend above (Pete Suchawreck on this site) saying there's a guy here on Brit Bike who modifies front forks for the Honda 600 CBR dampeners

We survived another race weekend, this time at Carolina Motorsports Park in Kershaw, SC. Not sure what it is about this particular track, but there seems to be more red flags here than other tracks. Hated to see it but there were 2 helicopter rides - thankfully both are in good shape, banged and bruised but expected to make full recoveries.
As for me, I just raced in Classic 60's 650 both days. Was glad Jake Hall was there this time - a good friend to race with. Saturday, he had the good position on the grid and got the crap position. He got the holeshot while I got stuck in traffic on the start. I wound up never being able to catch him, I don't think I was ever more than 100 yards behind and sometimes much closer but he hung in for the win and I had to settle for #2 again. Sunday saw our grid positions switched. We started behind the Classic 60's group (mostly Manx Nortons) and some of them are really fast bikes and riders. Anyway, on the start my 17c Triumph got through those guys as well as our 650's and got to turn 1 in the lead! Nobody more shocked than me! However, I got the red flag on turn 14 and we all retired to the pits. Alex McClain low sided in 12 and was struck by another rider. One of the aforementioned helicopter rides.
I didn't do as well on the restart but still got in front of Jake and proceeded to dice with him for 8 laps. I think we switched lead 3 or 4 times. I blew the 3-2 downshift going into 1 and somehow wound up in 4th when I should have been in 2nd. That took a bit to make up, but the bike was up to it and I was able to motor him and take the win.
The bike ran great, I was a little concerned as I had ordered a primary chain from Andy in England and waited until last week to install it - well it was a tight fit. I mean remove the adjuster tight. As it got some track time on it it started getting some slack. Guess I'll find out what the damage is when it gets opened up. Tuning seemed to be spot on, the bike is just easy to ride - it starts making power at 4k and doesn't quit. The gearbox is still puking oil out even after the vented cap was installed. I think I need to figure out a better way to relieve pressure. It's blowing out the inner cover vent hole and the high gear sleeve.
All in all though, it was a great weekend with a lot of fun racing. Lets do it again!

Mike do you race at Mid Ohio?.......The tight primary chain is something?


Kevin...You need heat in the damn shop! One time my friend was changing a starter motor on a plow truck out in the snow..He had a Salamander heater blowing hot air ...The heater ran out of fuel, he had some problems but got the job finished..His coat was froze into the ice that had melted and then refroze...He had to wiggle out of his coat...

Kevin, send that pile of Triumph bones to me - I'll get it started for you!
Thanks, Konan, appreciate the thoughts
Mid O? I wish. Always a treat to race at places like that. Unfortunately, and I don't really know the details, AHRMA and AMA had some sort of tiff and we don't do Mid O anymore. I guess WERA is there in July for vintage fest but their vintage program is lacking compared to AHRMA. It would be fun to ride the track but I don't think I'd have anyone to race with.
The chain.... I don't like them tight. Motor gets hot, expands, chain gets even tighter, bearings go poof...
I'm coming up to NY to visit Mom soon. I'll get with you earlier this time, maybe grab lunch and a beer

never fear, it will be done.

the track bike is missing nothing now but pushrods, headbolts, rearsets, and shocks. but the LSR is on the lift, with the motor on the stand. that has to go back together.

in the meantime there's snow on the ground, but the peepers and chorus frogs are out anyway, the meadowlarks were calling at sunrise today, and we're past the equinox.

i come alive in the spring, and we're here.
