I picked up an '01 TTR225 today to use the top end and crank for a stroker.



Kind of a cheesy motorsickle, actually, even by TW standards. Or at least cheesy in different areas, better in some others. The TTR has a better airbox and general component layout than a TW, IMO. etc. But a dedicated offroand bike without a kickstarter? Not on my watch.



It does have some cool features and parts that can be used either to improve a TW or are identical items if you're in need of parts. Some are fairly common knowlege by now, others less so. As I part it out I'll make note of these as best I can. Some things like the carb and fuel tank probably have clearance issues on a TW, so I'll slap them on one of my frames to check.



XT225 models will share more parts with ours. If I ever get my hands on one I'll try to do another post.



I'll update by editing in this window, so if you're interested check back, as that method doesn't return the topic to the top.



What's hot:



Most folks know by now that the crank, barrel and piston and head can be swapped into a TW to produce a 225. Cylinder can be used alone on a TW to allow overbores with the TW crank up to 72mm, or the entire engine can be swapped into a TW but you'll still have to split the cases and install the TW transmission.



Stainless steel headpipe- direct swap. Here's one all cleaned up. I'll have to dull this one up a bit, cuz I'm The Antichrome:







Kickstand- 1 inch longer than TW. Direct swap



Master cylinder-identical to TW. Rubber plug in brake switch hole, but it's there.



Brake line- 3 inches longer



Clutch lever perch-identical to '01-up TW. Has rubber plugs in the mirror hole, uses same safety switch. Cable not the same as the TTR clutch arm operates from the left.



Remote cable-operated choke- operates by a knob at the bars. Standard Mikuni plunger, need to verify if it TK thread is the same.



Skidplate-pretty cheesy, but aluminum. Better coverage than a TW plate, but no tougher. Fits with the TW rear hook bolted onto it. Has a nice ventilated rubber cushion between it and the crankcase, not a bad plan for a TW.



Handlebars- Same as ours.



Fuel petcock- Fits our tanks. Has a big, chrome easy-grab knob that looks like it came off yer grandma's stove. Ronnydog has one on his XT txnk. I gotta measure the fuel reserve.



Shift lever- folding-tip style. Fits.



Rear sprocket guard-same



Rear brake arm- Fits. More leverage.



Snail adjusters- Same. In fact all Yamaha snails appear to be identical.



Foot pegs- Fit. Aprox. 1" longer, but same width.



Fuel tank- 2.8 gallons, if the factory is correct. Some people have done the oversized Clarke versions of this tank on a TW.





What ain't ( or in some cases could be, but with major alterations):



Rear shock: The TTR uses a linkage and therfore the spring is way too wimpy to run direct. The shock is 14.5" long, putting it in nosebleed territory in terms of ride height. HOWEVER it is fully adjustable and is the first shock I've encountered which will readily accept a stock-length TW spring without a spacer.



Left footpeg mounting bracket- With careful layout and redrilling it COULD be used to correct the rearward offset of the left peg, which drives me nuts on long rides. I end up with my heel parked on that peg and the middle of my foot on the other.



6 speed tranny- The TW ouput shaft can be machined to accept the gear stack. two of the gears are thinner requiring a custom spacer and a snap ring groove to be cut into the shaft. Fairly involved and not cheap, but doable.

Hey lzrdbrth,



I am interested in the kickstand and possibly the headpipe if it's in good shape.



Let me know, thanks!

Brian, you know I owe ya one. Kickstand,no problem. The header's going on mine




For everyone else, I started this thread for informational purposes NOT to sell parts.



There will likely be plenty of stuff I'll part with once I've looked it over, but I'd rather disect the thing to see what fits and what doesn't in terms of use on a TW before I part with anything right now. Once I'm done, some of the parts will be fair game.



If you needed a master cylinder, for instance, and eBay had no TW master cylinders, wouldn't it be nice to know you could be safe bidding on a TTR master cylinder and not worry about it fitting? I'm gunna check all that out.



That's the point of this thread, and to see what TTR parts are upgrades for our bikes, or make mods easier.

It might also be of note that some of this information would give an idea of what *aftermarket* parts might fit, as well..

Hey Russ,



Sorry I missed the point of your thread.



Thanks for thought, but you don't owe me. I just feel bad that you lost out on our other deal.



Just keep me in mind when you do get around to parting the TTR out. I've got a Blaster shock waiting to be installed and the extra length on the TTR kickstand will help level things out a little.



(I look forward to the new regime and your rule as the Sublime Benevolent Dictator!)

what?! 82nd bike? I thought he only has 13 which would make it 14th bike. I wonder where he is hiding all of the other bikes? Nah, I have already claimed a couple of the parts off the TTR for my bike anyway. Lucky for me since being Ms. Lizrdbrth, I get first dib on things

What did you buff that SS Header Pipe up with?


800 grit. If you take it to 1,600 or 2,000 it will shine like chrome.



Not as diffiicult as it sounds. Wrap the paper around the tubing and twirl it, or (faster) put it in a well padded vise and buff it like a pair of shoes, then procede with the next finer grit. Don't move on to the next grit until you have even sheen overall, and keep the jumps in grit size minimal. Don't try to jump from 600 to 1200, for example. Quit once you're happy. I really wanted more of a matte look, and should have quit at 600.



I've polished aluminum to show quality using this method as well. Follow up with a paste like Simichrome or Mothers on aluminum and it will blind you.



These days I'd rather have my butt kicked than maintain polished surfaces, particularly highly polished aluminum. Stainless tends to shed dirt and mud even better once polished, so I'll make a token effort at polishing it



IMO on a headpipe the more brilliant the overall polish the worse the inevitable pitting from gravel and road debris will stand out.



YMMV

Russ, I realize I'm talking an older ttr, but if you recall I had just purchased a plastic ttr 350 tank and a seat from the same bike when you were through here. While the front mounts are different on the tank, I'm sure it could be adapted to the tw (but only for a move from 1.8 gal to 2.6 (still that .8 or probably 60 miles you might not have to walk). The seat is alot like the xt350 seats (i.e. has steep and short horn), but might be fodder for a custom fit with a larger tank. So many funny parts and so little time. Ride on. Tom

Not much of an inducement since I only have one rack............ Looks like you are putting 'together' a real good (sticky) post. Hope VulDub is watching and ready to lock in place once complete. Thanks again Russ. Gerry

Frankly I didn't find that many parts other than the ones listed in my original post to be of much value. I pulled the motor, kickstand and a few other goodies and sold it today to a kid who taco'd the wheels and front end on his.



The only thing I left out was the larger Mikuni carb and matching boot which could be of some value for a way built 200. Otherwise it's pretty much overkill since the valves and ports are identical. The boot is just a funnel. Same valves, same ports, minor casting variations..



I plan to put a dial indicator and degree wheel on the cam to see if it somehow justifies the bigger carb, but I sorta gravity tested my dial indicator and that will have to wait.



I'm betting the Xt's will have a greater assortment of usable parts in terms of things like stators, regulators, CDI's, fairing, et al.

Any particular range of years for the ttr...I like that header pipe. I already have the polished power core pipe...but could use the header pipe to match.

Not sure, Brock. This bike was an '01 TTR225 and had it. Someone once said that all XT's had them, but I've seen quite a few with mild steel pipes.TTR230's all appear to be stainless in eBay pics. Some have also had to shorten theirs and inch or so to get them to mesh with the TW mufflers, so there could be minor variations. This particular year bolted right up, so if you can find one for an '01 I can safely say that it will fit and it will be stainless.
