Yamaha TDM / TRX 850
Factory Pro Series "Y85"

The TDM/TRX's are the first of the "funner than heck" big bikes to drive around San Francisco hills, stairs, ramps and warehouses - the original Japanese "Hooligan" bike!
Wheelies forever - super balance - and handling? Described as "eeeeaaaasssssyyyy" and super stable - the epitome of legendary Yamaha chassis balance and stability.
The only negative? It's got a pretty high seat height - 5'8" rider height means tiptoes at stops - Aww shucks - Who cares! You can't ride with your feet on the ground anyway!
A bit of carb tuning (check out those nasty needle jets as they wear out pretty quickly) and the Factory Pro exclusive Shift (improvement) Kit makes it even snappier and gigglier to ride!

The internet's #1 choice!
"TDM Ti ProKit!"

This is "the" #1 jet kit choice of TDM riders.
Best lowend and midrange and the best, if the user / tuner tunes for it, mileage.

Uses Titanium needles. Adds more low-end / midrange, if the proper main jet is selected, more topend power. Easy to install and tune - no slide drilling.

Note
 If you have a 1999 model with 40mm carbs, marked; Type BDSR38, id, this kit will not work -


Hi, I had a Ti-Pro Kit installed on my TDM by Mammoth Motorsports in Rohnert
Park recently. Much improved performance! Was wondering if you had stickers
that I could put on my bike so I could proudly display this modification?

New Factory Pro TDM Needle Jets!

Factory Pro manufactures replacement needle jets (called emulsion tubes by some) to original factory specs. The needle jet orifice wears oblong in as little as 5,000 miles and is particularly aggravated by "in town", low rpm operation. The result is excessive richness at low rpm that can be partially compensated for by lowering the fuel level.
A direct replacement for worn, original items. Accepts standard Mikuni main jets and our Factory Pro Carb Recal Kits. Also fits Ducati, YZF750 and FZR1000's.

This the THE nickel plated Factory Pro replacement!

Increase airflow over stock and if any air filter could really last 1,000,000 miles, these quality, cleanable filters would be right there!
Ignition Advance Kit

Not available for the TDM, TRX series. The ignition trigger coil is triggered by holes milled into the crankshaft and not easily modifiable.

Factory Pro Shift Kit

Trans Detent Arm Kit
SHFT-PRO-YAM-4
$89.95

Only fits the TDM. If you have a TRX 850, you can be a guinea pig. You'll have to send in a stock detent arm and stock detent spring for a free kit, if we can do it - email Marc

Put your gearbox on a diet!

No - you can't loose unsightly gear weight, but you CAN snappen up the somewhat lazy TDM gearbox with the new Pro Shift Kit.

We don't make a kit specifically for the TDM, but, if you supply your own clutch cover gasket, you can use the same kit as the fzr1000.

Makes shifting MUCH quicker and virtually eliminate missed shifts. This is exactly the same spring kit that Yamaha Racing has used.


Helps prevent additional damage to second gear and second gear shift forks. The kit won't fix a worn gearbox, but it will almost the eliminate missed shifts that cause the damage in the first place.

The best tool to accurately measure float heights. Works on nearly every carburetor.

Required to set the 38mm Mikuni carb sets.

Info about the"
"Slide Step / Notch / Ledge"
The 1/3 width step, built into the slide, where the needle sits, is designed to lessen the "rattling" that the needle does in the needle jet (you, know.... the hole that eventually wears out in every carburetor with a slide and causes the bike to run rich over time).
It tries to keep the needle leaning up against one side of the hole , instead of letting it rattle and beat both sides of the orifice oval.....
That step is in most Yamaha Mikuni carbs for the last decade or two -
The needle jet still wears, but at a slightly slower rate.

Factory Pro makes a tougher than stock, nickel plated stock type replacement needle jet (commonly called an "emulsion tube"). It's easy to replace and if you can do a "jet kit", you can replace the "tubes".
See above to buy a new set!

Float Height Setting Trick for 38mm "Mik's"
One of the problems with setting the float height on the 38mm downdraft Mikuni's that come on Ducati's, yzf 750's, tdm 850's and fzr1000's, is that the golldern white plastic "float cage" keeps popping out of the carb body unless you hold it in.

When you hold it in with your fingers, you always flex the cage frame and distort the reading that you are setting the float height at..... Aaarrggghhh!!  :-)

After spending 45 minutes setting some yzf750 carbs in the sweltering Mid Ohio heat of summer (there's a funny egocentric dynojet story to tell, here, btw), I decided to make a float cage holder and sell 'em! I'd make a million  $$!!

When I got back to work, I set up and made a pile of cute little flat braces.

As I was sitting there, admiring my cleverness...... one of my parts guys wandered by and asked what was I making? I showed him that you could just take my clever little piece of aluminum and hold those float cages right tightly up into their seated position - so you could get consistent float height readings.

He says.....
It looks like you could just put the float bowl on with the front holes on the bowl lined up with the rear holes on the carb body and slap some screws in and it would do the same thing...........
I bought him lunch with the million $$ I didn't make....

Hello.  Here’s the pics you asked for!  Thanks for the help, the bike runs BEAUTIFULLY now, lots more power!  The front end now comes up on the throttle – whereas it didn’t before!  There’s another pic in there too where I used a bar code to measure the bowls.  I found this a lot easier than using a ruler.  I measured the bar next to the number “8” on my barcode to be the recommended height on my bike – 14mm.

-Mike Beary

Thanks Mike, for the pics!

Artisan Crafted Fine Cheeses – Since 1865       

Specializing in Handmade Brie & Camembert

Marin French Cheese Co., also known as The Cheese Factory and Rouge et Noir is not just the oldest cheese manufacturer in the country, but a vacationers and day trippers destination as well as a unique part of American History. Located north of San Francisco, east of Napa County, west of Pt. Reyes and Olema and south of Sonoma County, Marin French has produced hand crafted Artisan soft ripened cheese since 1865. Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.


 

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
Edited to the tunes of Chemical Residue by Herbie Hancock.




Maybe in next rewrite, he'll fix the ignition timing and dyno chapters...
Otherwise great book with great starting ideas.
