Wicked Here's my T-Dub!

[IMG]file:///Users/tophermira/Desktop/551846_3137827572263_371046117_n.jpg[/IMG]Hey Folks,

New to this forum. I joined when my buddies XL was almost stolen here in New Orleans... and then I discovered the TW thread!

17 years ago I was 13 years old. I went into my buddies garage and saw his fathers TW for the first time. I knew that someday that bike would be mine! 17 years later, I offered to do some tree work for the bike! I got the bike after being garaged for almost 20 years, with only 400 miles on it! A dream for sure! This summer was my first time owning an on-off! I grew up riding a KX 125, and the dream of an on-off was always the highest goal... Street legal dirt bike!

I had some great adventures on it this summer! I will document more know that I know there is a forum!

Thanks for being here!!

Looking into swapping to the 130mm front drum using the backing plate from another Yamaha that we can get here in The States. Gotta love Yamaha. They gave the lowly TW125 the bigger 130 rear, and it can barely get out of its own way.

Looks like they did the same thing to the XT guys, if it's any consolation. Put the little brake on the street-legal bike and the big brake on its dirtbike sibling.

We've got twice the rubber on the ground, and some of us have way more than that....
so will the bigger drum bolt up or do you have to modify anything? my tw rear drum is pretty worn out and grooved so a bigger drum would be super!

It's major work, in a minor sort of way? It won't be a bolt-on and it will require scrapping a front rim for the drum and grinding on the swigarm brake locator tab.. I'm not sure most folks will be all that into it, but I happen to need it.

It's been done before, but using the TW125 backing plate, TW125's were never imported into this country. I'm looking at a few backing plates for the one which will require the least modification.

NP. I'm blessed (cursed?) with a lot of spare TW parts. Once I get this worked out with U.S. parts I'll post a how-to. Let me destroy my own stuff figuring it out. lol.

Hey Lizrdbrth, in that post on TW200 Forum the pics show some clearance needed
where the spokeheads impinge on the drum. Why can't you just drill out
each section where they touch? Since drums aren't waterproof, it shouldn't
make any difference and, in fact, I remember years ago that when a
Studebaker made a run on the salt flats they drilled the drums to increase
airflow which cooled the brakes thereby increasing the braking ability. I
was going to try it on an old Bronco, but used Chevy discs instead.

There again I have a slight advantage courtesy of my pile o' parts. I have a bare rear hub to use as a template. I don't plan on drilling all the way through, but I can use the spokeless hub as a template to mark the holes from the back side, then face off the offending areas with a drill bit just enough to clear the spoke heads. If it works out we can pass around my hub to those who want to do the same, or they can send me their brake drum.

Er sumpin'. I expect not more than a handful of us are gunna be into it.

The YTZ7S battery has the same, or better power than the stock battery. However, the YTZ7S is a little smaller, and lighter. I have received very good service from the MotoCross YTZ7S battery I installed in my Zong.

There are a couple of "Sealed" batteries that fit. The YTZ7-S is factory sealed. The Yuasa branded battery of this model is about $120 MSRP. The one linked above at Battery Stuff seems decent at $84 if it truly is made in Japan.

Another option to consider is the TruGel from BikeMaster. They are also factory sealed, and at the dealer show they had one on a bench powering a running light and they drilled 5 different 3/8" holes in it and it kept working. Our shop sells the TruGel for $70.00. They also have a two year warranty versus the one year warranty of the Yuasa.

More food for thought... Both the Yuasa brand and Battery Stuff brand are 6 Amp Hour batteries, so their maximum charge rate is 1.8 amps. The OEM and the TruGel are both an 8 Amp Hour battery with a maximum charge rate of 2.4 amps. I've never been able to determine what charge rate the regulator on a TW puts out to charge a battery but the smaller battery has a max charge rate 30% less than OEM.

Sorry for nerding out but I've been dealing with batteries a lot lately so a lot of this knowledge was fresh in my mind.

Motocross builds batteries for Yuasu in the United States of America. My Motocross battery is very well built, and has served me flawlessly for tens of thousands of miles. You might enjoy reading the information at the following link.
