View Full Version : Anti dive by pass plates

Hi, my name is Timothy and I run a small CNC shop making motorcycle parts. This is my full time employment. It's called TracTech Manufacturing and you can find it at www.tractechmfg.com (http://www.tractechmfg.com). I offer a discount for members of this forum so use GSR10 for 10% off any parts I have in stock. For those who might recognize the parts, yes I'm the same guy who owned Demon Speed Racing. Yes, still going, I just changed the business name this year to a more 'official' business name. I can answer all your questions about my products so feel free to ask.

Ive got a pair (from Demon Speed) on my bike and they fit like a glove and work great.

Heads up for another market area.

Just the pressure switch plate with extra ports for a top end oiler would be useful I'm sure to some folks.

I couldn’t see any plates for the GS1100, are they the same as the GS750s that you have on your site?

Hi guys!

The GS1000 and the GSX1000 is the same as the GS1100.
I included dimensional pics of the plates in the gallery of each set so you can measure up your forks to make sure it's the correct one.
European and Australian GS's had different anti dives in different years.

If I had an original pressure switch plate I'm sure I could make the extra port version easily.
Discounts for GSR members would still apply.

I found a pressure plate off of a GS1150.
Is that the same as the GS1000 and GS1100's?

I don't believe they are. When I swapped my 1150 forks on, my 1100 bypasses wouldn't fit if I remember correctly.

Yes, GS1150 and GS1000 anti dive pates are very different.

Do you have a template for the anti-dive units on the 1981-1983 Yamaha XJ750? I didn't see them on your website.

If you do, I'd be interested in purchasing a set. If you don't and are interested in creating them, I could send you units to use as a guide.

Just let me know. Thanks.

Hi Griffin,

As far as I know all Yamaha anti dive units were identical except for the XVz1200 which used the same internal dimensions but had a different exterior profile.
So the RZ500 or FJ1100 anti dive by pass plates should fit.
If you want to make sure, in my website, www.tractechmfg.com (http://www.tractechmfg.com) there is a picture in each listing with dimensions you can double check with.
I also offer a 100% fit guarantee. That means I pay for shipping there and back as well as a 100% refund if I recommend the wrong one.
If it is different, send me your anidive unit and I'll send you a free set for being the first one.

Sounds good Timothy. I'll measure it and let you know.
