I'm really starting to get sick of motorcycles. For the first time ever I cut through a con rod to remove a piston from an engine tonight.

Hey...my favorite way is to chisel off the top of the piston and grind a groove out of the side of the piston from the inside...that usually loosens it up enough to come out. Only takes about all day.

PS. Check out what we did to Mary's 50cc engine last week.

Probably wasn't a good idea to let her run without a tachometer. One new $400 trick cylinderhead down the toilet. The price of performance I guess.

Ug. This RZ350 I picked up... piston with a melted hole through the exhaust side, aluminum on the crank bearings. The clutch fiber plates were broken, so bits of the fiber plates were wandering through the gearbox. There's a very nice aluminum paste on the bottom of the cases and a few shot transmission bearings.

I'm really beginning to hate working on bikes. I spent way too much of my free time working on these damn things. And riding isn't the thrill it used to be. I'm seriously thinking of getting rid of them all and getting into a new old hobby. They're ceasing to be fun.

Had a great half marathon this weekend. 1:40 = 7:38 pace for 13.1 miles. I'm pretty happy with that.

Anyone want a Kawasaki H1 with a H2 engine in it? Only $2K if I know you before I put it on Ebay.

Dude, I know what you mean. Sometimes you just have to walk away from it for awhile. I've regretted selling stuff though. You'll warm up to it again...

That's pretty damn good. Yikes.

We were supposed to race this weekend, got the word that it was cancelled Friday night, made other plans, then late Sat. afternoon got word that the racing was back on. Too late for us to make it. Instead, we ran our XR100 and an old Suzuki dirt bike on a local motocross "practice" track. Had more fun doing that anyway...and I'm feeling the muscles today. Turned out to be a great weekend.

Yeah... I've already sent in my pre-entry for the next race... So I'll do that one. But need to rebuild the gearbox before then as the shift forks must be bent (pops out of gear too easily).

I need to thin out the garage. So many house projects piling up as well.

The race winner, the guy who ran the whole marathon, not just the half like me, finished about half hour later. Crazy type fast. That's like running a 5:45 pace for the whole race.

Nice. Sometimes riding for fun is... more fun. Good to hear.

I keep telling myself I can take a year off if I want and consolidate things around here....but somehow I can't.

I learned early on, pick a bike, stick with that bike until you win it all. The reasons being....you confine your spares, books, knowledge to a particular bike and it streamlines the whole process. I've even gotten rid of most of my 175 verticle spares so I'm concentrating on a particular year range of a particular bike. Once you have your sources, info and personal knowledge in order for a single type of bike the whole thing becomes easier.
I can do this because in reality I have no great love for vintage bikes. I'm trying to build a parts and knowledge base to make my choosen vintage bike as modern as possible as far as maintainance and duribility are concerned. I building a database of knowledge that lets me go from step 'a' to finished bike with no if's. A roadmap to a competitive, durable, easy to maintain vintage race bike. Not necessarily cheap...but then modern racing isn't either.
I'm about 1 year away from being able to say...you want a 26hp 175 then you do this, this and this. You want it to weigh 200 lbs, you buy this, this and this. Same parts each time, put together the same way each time. It's a lesson I learned back when I was working on sprint cars that raced about 35 weeks out of the year....you gotta have a reliable system that gets a competitive car on the track every race if you want to win anything.

It can be boring as far as experiencing different bikes etc....but like I said, I'm not in love with the bikes.... I like the racing. So I'm trying to come up with a system that goes from junk 175 to nice race bike in a quick and direct manner. It's the way RS125s are done, there is a small envelope of modification and tuning, decide your budget, pick your parts, go racing. On Monday...repeat.

I can only imagine the headaches of trying to sort out various brands and models of race bikes....for me it's a 3- 4 year project to get a single model of bike sorted to my satisfaction.

that's why i love the cb350. if you build it right the first time, do some minor maintenance, it will run forever. i think wrenching stinks. especially wrenching trackside. i'd rather have a beer in hand and get to bust aaron's balls about his program.

jb, aarons got alot to live up to eh?? wow, at least you can say she thorough! look at it this way, chris' jugs and top end cost him almost 4k. when the pin moved and gouged the sides of the jugs, people were wondering why hes not back out on it. yeah, i said almost 4k.

you should see the bike chris constantino built. the rotax powered special with the home built frame and front end. makes what youre doing look like building balsa wood airplanes. onboard telemetry and the whole 9 yards. todd comes in, gets off the bike, chris plugs in his laptop, and tells todd they can go one smaller on the rear sprocket becasue hes still revving too high for too long. monitors engine speed and all kinds of other crap. really cool. and the bike is basically vintage. if you havent seen it, you gotta check it out. and the pipe he built is just retarded. i didnt have my caera or i would have taken about a million pics of it. if you havent seen it, definitely make it a point to check it out.

and sorry about the motor. dont you run a rev limiter??

That's data aquisition...not telemetry.

If I build balsa wood planes...what do you build...big steaming piles of shit? Hehehe.

at least mine dont blow up from some girl riding them. and ive even let aaron prove it!

Telemetry

The science and technology of automatic measurement and transmission of data by wire, radio, or other means from remote sources, as from space vehicles, to receiving stations for recording and analysis.

sounds like what im talking about.

you weenie

in the meantime, if i need pistons and valves annihilated, i'll know where to go. til then i'll keep racing the "heaping steamer". now make sure you dope those wings before sanding.

it is a trick scoot, you gotta admit.

Telemetery is sending the data from the bike to a base station in the pits. Data aquisition is recording data from on board sensors to a data recording device on the bike. You know nothing of what you speak. But you are good at looking up definitions.

When you can out run my girl on her bike half your displacement you can be a real man.

Yep, us folks that run up front do occasionaly blow something up....not something you'll ever have to worry about. Maybe if you add a milk crate to your bike people will assume you found your way onto the track on your trip back from the comic book store and they won't laugh so hard.

(data acquisition) Storing a series of measurements
over time, usually from a sensor that converts a physical
quantity such as temperature, pressure, relative humidity,
light, resistance, current, power, speed, vibration into a
voltage that is then converted by a digital to analog
converter (DAC) into a binary number. Data logging hardware
may have several DACs for multiple simultaneous measurements.
The hardware usually connects to a parallel port, serial
port or USB port on a PC.

and id bet if he wanted to set up a wireless on it he could.

youre just jealous cuz hes got neater toys than you and more time to play with them.

and when you say "up front", does that mean aaron up in front of his garage??

yeah, on my way to the star trek convention after picking up those comic books right??

Wireless is a whole nuther ball of wax. Sure it can be done, he could do it, I could do it....you can't.

I got lots of toys I never even bring to the track....and I work three days a week.

I am jealous.... that you are blowing him instead of me.

no, i cant, but i know the people who can do it for me. and thats whats important! i have a very close relative who does signal processing and information compression and is an electrical engineer with degrees from hopkins and drexel. hes way smarter than i am, so all i have to do is ask or pretend i dont know what im doing (which is easy) and he does stuff for me. but i have no need to have more crap on my bike.

and dont be jealous, i can see a nice powermatic shaper or saw in one of those photographs i wouldnt mind having either.

and im not that good.

well, jeremy says i am, but aaron swears youre better.

hey, a little competition is healthy right??

and besides, i said not taking anything away from you. the guy has an entire machine shop, probably almost as nice as franks. what you manage out of your garage is completely different.

3 days a week. you sound like my mom complaining. im at my shop usually 6 days. its nice to collect a check every week isnt it. the only benefit to my work is i can go racing whenever i make enough to do it.

whats the clever dog racing menu looking like for june??

We will be kicking ass at NHIS on the 13th and at Beaver run on the 25-26th.

Two inch extended swingarm is mounted and ready to go. But...My T500 front brake is worrying me...no cracks yet but the hub flexes a lot more than I would like. I'm getting a CB77 front brake tuned up and ready to go...should lace right up using the same spokes.

Next time you talk to Chris M. ask him for a good source for decent brake shoes to fit the CB77 front....not Vintage Brake...cause I'd like to use it this year.

why the 77? they use a 36 pattern. the 450 has a 40 hole pattern. seems like more spokes are better. especially with your weight. although, combined weight is lower, so maybe its not such a big deal. im running a 450 which are getting to be difficult to find now. frank c has one though im pretty sure. im picking up my new brake at nhis i hope. im going to run out the year with the 450 though. i have a buddy who might be building a bike and he has dibs, but if he bails, i'll give you first shot at it. its got the vintage brake setup. up to you though. i wont know anything til after the season ends.

chris will probably say mike morse. he runs his stuff. and the gt750 with stock linings. turnbull runs the buffalo with the vintage brake stuff on the rig, and stock linings on the solo bike.

drop chris a note. he'll either ignore you or tell you everything.

i meant what will you have out. will the 50 be resurected in time?? who else is doing beaver? you know??
