I was watching the TW200 forum a while back and noticed one of the guys building an oil cooler adapter. I bought one and put it on my XT225. It works wonderfully. If that guy ever runs another batch I highly recommmend the mod.

NICE! I'd be on that like a cheap date. Keep us posted. When we were riding in the dunes I thought my bike was just gonna melt down in the heat. The valves and/or cam chain were making a lot of tapping and clacking noises but she pulled through as always. Pretty hard to break these bikes but an oil cooler would be nice insurance.

You're exactly right. You can hear the heat building up. You should hear my XL600 with no oil cooler. I shut it down in traffic jams and push. It sure sucks when that happens.

I had one on my Honda Mini and its was huge in the improved cooling. We need a hand on "How to do it" that is "Do it right!
In addition to the oil cooler, what kind of hoses would work best?

Please don't say that it can done with 2 straws from Mcdonalds....Its less expensive to buy good parts and do it right!....IN THE LONG RUN!

Grateful for the great replys so far!

i like the oil cooler idea as well, when i took tw into pisgah natl forest...some of the trails were in pretty rough shape, some were just blocked with downed trees.





it was hot in there with very little air moving. running the tw around downed trees, thru the woods and weeds and mud...i heard the engine ping quite a few times...it was runnin hot, and could have put an oil cooler to good use..

i am definetely interested in an oil cooler..

I'm not clear on why you say the tire needs to run backwards. The direction of rotation is the same for the front and rear wheels.

Can you please clearify your statement/reasoning for me?

Hey Pete, thanks for the info, I would like to know where you found the 58 tooth rear sprocket for the tw200, wife might like one on her T-Dub?

Thanks,
Steve

Sprocket Specialties (Specialists?) is where I got my aluminum 58 tooth.

Frank,
A few tires have an arrow or similar caution that they are "directional" (like chevron tractor tires) and will load up/not "clean out" if turned back wards.
Because your front wheel is NOT "driven", except by the ground pushing against it, you need to figure the road surface is "driving" it instead of a drive chain.
So, if you wind-up with a good gnarly tread tire on the front that was made to be used on the rear wheel, if it says "directional", it may work better/be more tended to "clean out" rather than pack mud into itself, if it is run "backwards" to the indicated direction of rotation.

Most tires are not directional, so I have caused some confusion probably for nothing....(Mea culpa)

Some of the auotmotive winter tires like Frank COlver used on the rear of his three wheeled T-Dub ARE directional, and that mebbe put the thought into my warped mind.

Also... Your rear wheel is the driving force of the bike... your front wheel often times carries most of the braking force of the bike. It will get better traction under heavy braking because of the reverse directional mount...

Please give contact info. for the builder of the "life support" system for T-Dubs.

Even geared-down (58 tooth from 50 rear sprocket), so mine isn't lugging hard climbing over rocks and up steep hills, mine gets as hot as a forge.
Since oil capacity for stock motor is only ONE measly quart, greater oil capacity plus cooling has GOT to be a help keeping temperatures down to where the little mill will last longer and run better under extreme conditions.
My T-Dub will be dragging a light hack, and Frank COlver's two T-Dubs have been converted into 2 steerable wh. fwd. one wh. in rear trikes, and both his and my rigs are run at low speed where you don't have the benefit of alot of airflow over the engine, as well as pulling a heavy load.
This is SO ''needed" an accessory!

Larger-than-stock-tanks (4 strike-outs....)

Been trying to get a larger capacity tank.
justgastanks.com, Clarke, IMS, and Acerbis do not make tanks for T-Dubs despite the little Yamaha being in production nearly 1/4 of a century.

I have a couple more inquiries out that I haven't heard back from yet, but it looks like I'll have to take a 3.3 gallon Mustang style chopper tank from Steel THunder Custom Cycles and try to make it work for me if I want a larger tank bad enough...
I'me already going to try a leather Velocipede solo saddle with coil springs under each rear corner from them...(Alot like the old Bates solo saddles like I had on my 1937 ULH 35 years ago.)
I'me going to "lose" all the blue plastic that I can, too.
With the new fenders already on the bike, this shoudl make it look "retro", and for sure be more waht bikes used to look like before I got old and cranky.

Thumb Dunlop 606 130/90 tire for front wheel

Just received my Dunlop tire and took it by a "good neighbor" who is still into bikes despite being older than I am, and who used to race quite a bit...

"I approve of the well-buttressed knobs. They won't squirm like siped ones or ones that aren't supported as well....Also, they'll provide a solid anchor for your screw-in ice studs from KoldKutter."

Even tho it is DOT approved for the street, this is a pretty gnarly knobby, designed for the rear wheel but being run on the front of my T-Dub as soon as I can get it mounted.
