EBay mostly. A good upgrade is either a DR200 or a LT230S, while an LT185/ ALT185 top end makes a low compression 153 kit.
The 190 kit I run is a NOS Wiseco piston that hasn't been available for over 15 years. Powroll does offer some nice stuff, as does Pro Cycle, but if you can get a good Taobao agent, you can get a whole 150 top end cheap.

I'll for sure be going with either the ProCycle or the Powroll 143cc 11:1 with the cams. It'll cost me the same to replace stock, EFF that! :thumbsup: One thing confused me, what do you mean a good upgrade is a DR200 or a LT230S?

Whoops!  A good CAM upgrade is either or, while a whole DR200 motor is a great upgrade. My bad.

Oh, no kidding? A DR200 will drop right into the 125 frame? I better do some reading!

Thanks for that reference material. I've stumbled upon an engine line I will enjoy messing with for a while :thumbsup: can do a lot with these little engines. Options are a noobs best friend I think, but what the **** do I know? I'm a noob.

I called ProCycle and here's what I'm gonna do:
HotCams Stage 1 setup with the stock piston
Oversized valves with stock springs
Dellorto PHB 26mm
K&N air filter


Unknown: Exhaust, no idea what to do about the exhaust. I want the one from EO the "Outlaw" would be sick on a cafe racer. But I honestly don't wanna pay 400 bucks for the thing, I doubt it'll perform so well I will forget the small fortune I paid. Especially since this is a daily-fun rider not a competition machine, otherwise I could justify it.

The low pipe? Yeah, it's a bitchin lookin mod for a street or flat tracker. You can get the Supertrapp cans on fleabay, and bend up a decent pipe using 1 3/8th exhaust tubing.

Yeah that's a really good point. The noob in me was hoping to not bend my own tubing but where's the fun in that??? The only reason I don't want to go supertrapp is the look. Those discs are ugly! On a dirt bike I wouldn't care, a race bike I wouldn't care. I want a classic looking can, hopefully like a short cone but not going past my swing arm.. Like the Leo Vince GP exhaust can. I am gonna put it on my TT when I get around to that beast. But, I'd really like something similar because I feel like that pipe they have on ProCycle would look silly on a cafe bike. I want it to make sense when you look at it. I think hotwing glass or some place like that sells cheap vintage styled cans, is there a bonus to cans or is it purely sound and breathing?



I was thinking something like this http://www.hotwinggl.../mufflers.shtml but keep the header pipe shorter about 3" and cut the actual muffler short about 3". But that might look retarded! I'll look around at other cafe and street tracker bikes and see if I find something I gotta have.

I would love a supertrapp though and just might go with it. I'll keep looking around.

You're right. I'm dumb. I am on Supertrapp website, for some reason I was under the naive impression they only had those cans with the screw sticking out of the end cap. Pft lol. I'm peeking at the ISD2 Cans, could paint one up and make it look alright. But there are tons of others that look neat. Def going with Supertrapp.

I'm gonna see if my friend will bend that tubing for me and get an exhaust that looks like that. I seriously think I'm gonna build this into a street tracker. I've been dreaming about it in the form of a street tracker and it's just sick what I'm seeing. Maybe the REAL outcome will cause me to be sick to my stomach as opposed to making me horny but still, I think I gotta do it. Whoop, that's it. It's a street tracker project now. A seat, handlebars, some wires rerouted and some new lights and blikers... VOILA! A street tracker. Whoooop. Gear it for torquey fun times :thumbsup: :thumbsup:  and some college kid will be thrilled to pieces, hopefully not literally, but what a way to go, right? :lol: :thumbsup:

What gearing ratio do you have for your bike? I want 60 tops and 0-5 mph in about 3 seconds. What gear ratio would you sugggest?

I've got the dirt version, so my gearing will he trash for the street. Its 13-48 with a 520 pitch chain.

It's 14-42 stock. So a 13-45 with the planned mods should be really good. With a cush drive and some decent suspension it'll just be a blast to ride. Might even go 46 on the rear or 12 on the front. I'm buying more sprockets for tuning. I'm ordering a 12t 13t and 14t for the front and for the rear a 44t 45t and a 46t just to toy with it. I might have more luck with a 15-48 but I dunno. We'll see. It'll be fun messing with it. Gonna get some extra links and a riveter though.

This is the official demise of the Project TT500. I'm going to transfer the title to my name, sell all the parts and focus on my new little 125 project. I think I would rather specialize in little bikes and focus on 100-350cc and stay out of the 400+.

Gee Pudgy:

We had great hopes at the start.  Most of us are here to save and fix old gems like the XT500.   ...instead of diving in big-time I think you could have done some inexpensive fixing and then had  a running bike that you could have learned on and had fun with, or even cleaned up and sold, now you just have a pile of parts....

The pictures of the bore and parts in your original pictures actually looked in better shape than many good running bikes.  My feeling is this bike could have been cleaned up and made a runner with just a set of points and a few parts.  Even the valves looked good....mind you it's hard to tell from pictures.

They don't make them like that anymore and I hate to see them get scrapped.

Well. Might keep it, I had high hopes too. I don't know. I feel sort of sick about selling it to be honest. I need the money but for some reason I have this strange sense of loyalty to the bike. Especially because it's the only other year models of the TT that can be road legal. I don't know. I'd like it if someone like you, or the others bought it. I don't want it to be scrapped. I kept the major parts, frame, triples and the motor. Everything else was trashed.

It'll cost me so much to get it back to normal. They resell for alot but getting the cash now to get it there is beyond me. I could finish my 125 and sell it, take the return and what little profit I make and put that into the TT, get it where I want it and sell it. But the problem is, I'm having a lot of trouble finding funding to get my 125 going. Nobody is hiring me, my wife's business is slow right now and bills are stacking up.

I had a guy offer me 275 for the triples and the motor. Almost took it until he told me he was gonna part it out. That made me feel sick, I don't want this motor parted out. Ah, hell!

Tell ya what! If nobody offers me what I want for the motor, I won't sell the thing. It isn't meant to be and I'll keep the big pig and it'll be the only 500cc I do. But, know this. If I get this 125 done and sold and still have this TT, it's gonna get on the road and it's gonna be one of the sickest street trackers you've ever seen.

With one of those underpipes, a handlebar change, re-painted tank, and a seat that molds into the bike a bit better, this would easily become a great looking bike. I really want that bike just to do this.

A TT500. I really like vintage bikes, especially Maico's and any of the older four strokes. I see a lot of TT's at the vintage races I go to and they look like tons of fun.

I'll sell you the motor and frame for 300 bucks. :thumbsup:

Sorry, but I can't. I have another project I am working on right now, and I am broke. All the money that I have is being poured into my racebike. I want to buy it, but can't.
