General Chatter / Re: Anyone ever seen or heard of these 2 into 1 pipes?

That's a really good point.  Not all design elements look right on all bikes.  For example a Manx Norton tank looks fabulous on a Norton but would look out of place on say and RZ350.

I agree that crossovers on a aircooled just look wrong and it's probably because we are used to seeing them on more modern bikes but they look out of place on a square old RD.  It's partly what we are used to seeing.  The brain tries to match things to patterns we are familiar with and if it doesn't find something to match with we consider that it looks "wrong". 

That comes from our ancient ancestors who looked out of the cave and when they saw something moving they had to quickly decide if it was something they could eat or something that would eat them.  It's all about pattern recognition.

It's also why some things look, smell or taste horrible but we still like them because they feel familiar.

I really like crossover pipes.  Their RD crossovers appear to be styled after late model TZ350 pipes which crossed over.

Did I read somewhere that they come for the place that made them for a one of the US Honda aftermarket suppliers and either the manufacturer started to sell them directly or that they were copied by a third party.

I used one on a Honda 160 and that application needs only one of the two pickups, so it essentially comes with a spare module  :whistle:

Turning Wrenches / Re: Needle Jet Question
« on: November 11, 2020, 11:40:01 AM »
You can work it out yourself.  Here's a TM32. 

Then get the needle dimensions and compare to other needles to see what changes where. Sometimes you have to buy a few needles to measure just to work out which might work.

What's interesting is how much difference a small change in diameter can make.  Had a guy a few years (decades ?) back with a midrange missfire at Gratten.  I was able to find a pair of needles in my stash that were only slightly different that I lent him and they completely cleaned up the rich miss.  Made him a very happy camper - and he even remembered to return them at the end of the race weekend.

I checked the dimensions the other day and the differences were so small.

You could be right. They need to work really hard to make that sort of small business work and Gil was well known in the ARHMA crowd so that helped - and there was less competition back then.  Now there are many more choices including reworked RFY shocks for the street.  ;D :clap:

I thought that I read somewhere that WORKS are back in business, now run by the late Gil's (owner of Works Performance) daughter or son.

Don't recall the details but that was only a few days ago I read it

Here it is:

As an aside, I had a pair of TZ350E forks "revalved" by Jim Rasheed at  Four and Six in Chicago (they have been defunct for years now)  and he spent days, welding up the rebound holes in the damper rods and re-drilling them until he got the rebound right and changed the compression damping with oil viscosity. IIRC.

I was going to fit a pair of Gold valves but decided to use FZR400 forks instead.  BTW, TZ forks look just like RD forks but damping rods are a little different and they are much lighter.

If it rips better with a P-0 with needle at the richest setting, that is confusing.  Taper starts at 35mm and at idle (closed throttle, the needle is around about the 25mm mark, so still on the root diameter.  Raise it fully and the taper will now start at around 30mm, so the needle starts to have an effect from say 1/8 onward.  By 50%, the needle will be at around 45mm ie where the needle jet sits in the metering part of the needle jet and will be much richer by then and with the double taper, will be way richer at the top end.

I'd try a pair of 6FJ41 needles from Jets R Us and see if that cleans up the top half. You may have to change to a single taper needle like a 6F9.

I may need those needle jets when you have it all dialed in.

It is the thread about threads.... :whistle:

I would expect that thread to be M10 x 1.25

There are some really nice Brembo billet calipers that are substantially thinner and lighter than regular cast calipers.  They cost a bit more too.

The pair I have came off an AF1 race bike and one is cracked, but the other I will use on a TZ one of these days if my brain doesn't explode over the election shenanigans first.

Just did - you've got mail.

Turning Wrenches / Re: Found - B8ES plugs
« on: November 03, 2020, 09:53:59 PM »
Well at least we know where the new NGK warehouse has moved to...

PID, Gas ain't what it used to be.  It's a whole different mix now and unleaded doesn't short out plugs with lead, but the plugs do take on a black coating that takes more heat to burn clean.

Try BR8EIX iridium plugs and zero resistance caps.

That TZ spring and lever is designed to work with a rear disk.  But the TD/TR3 lever is similar and the spring is the same IIRC.

The spring locates on the footpeg mounts which are tubular on a TD or TZ.  The red frame is a TD3 fitted with a modified RD/R5 rear wheel but the spring is not fitted. The black frame is a TZ350E

Hope that helps.

XS650 disks and carriers fit fine on a TZ250/350 wheel and the forks are perfect for a stock RD caliper which works just fine on a TZ.

And if you can't find a good TZ250/350 C/D/E front end or and F or G front end, try a pair of XS650 sliders on RD forks. The sliders are longer but take stock RD type calipers and work with 298mm disks.

Always more than one way to skin a feline.

Or get a complete RZ350 or FZR400 front end and upgrade wheels and brakes.
