Hi, I'm new to the YSR scene, and have a few questions i just purchased a mint 90 YSR from the ysr conection classifieds. I will take delivery via Forward Air on friday, can't wait!!! take a look below... http://www.billsworkshop.com/ysr50/ysr50.htm
the bike has a Toomey pipe that is in like new condition other wise it's a stocker. the owner claims it will do 55mph on level ground and sinse i live in florida, that's all we have is level ground. i was wondering how much more mph could i get by changing the stock counter sprocket (12tooth) for a 13 tooth sprocket. also what about a 20mm carb from team calamari...will the carb net me any more mph? is an aftermarket carb as reliable as the stock one, or will i always be having to adjust it? From reading all the forums in other web sights i know that going to a carb larger that 20mm isn't streetable. what about just buying the air box mod kit from TCR, which will get the most for me. TCR sells a stage 2 kit that consists of a performance exhaust, air box mods, Dyno jet kit, and the 13 tooth sprocket for 249.95, which sounds good except i already have a great exhaust with the Toomey. TCR claims this kit will get me 60-65 mph. will just getting a 20mm carb and 13t sprocket get me there or should i just buy everything in the kit except for the pipe. thanks in advanced.
you are the SOB (JK) who bought that bike. good move mate. that bike was certainly a sweet one. had everything in tact!
nice buy.
what did you end up paying for it if you don't mind me asking?

send me a PM with your number. I live in southern Florida as well.
I can go over all the mods I bought from TCR and tell ya what I've experienced from it.
And yes, I'm at 195 pounds and mine will do over 60mph on straight level ground.............pretty impressive with a piston that is the size of a salt shaker and only produces 7HP's.........
send me a PM and we can chat bout it.
Oh, and get that nology Hot wire from TCR. you will definately notice a throttle response difference. I also have the 20mm with the K+N air filter and the twin stinger exhaust pipe but give me a PM.

thanks for the info guys. i ended up purchasing it for 1900.00 and the shipping cost was 350.00 along with an addtional 50.00 for the seller as he was doing the leg work and had to buy a combination lock for the crate and some tie down straps to sucure the bike in the crate, so the grand total is 2300.00
so the 13t sprocket nets 5-10 mph
what about the 20mm carb vs the 24mm carb?
are carbs simply for torque throughout the rpm range with no actual top speed gained?
also is the seller off with his estimate of 55 mph?
I am pondering the thought of ceramic coating whole pipe (minus the silencer) for that clean polished look. is this wise or not? will it have an effect the power ban?

2300 is a great deal for a pristine looking bike. With those parts currently onthe bike, 55 is not out of line with stock gearing 12/42.
The bigger carb will help out in the torque dept. A bigger bore will also do that too. Porting the cylinder and milling the head will yeild even more HP, but narrows your spread of power.
In other words, everytime you strive for that extra HP, you narrow your power band to the upper rev range (read: you won't have mid or low end power). As a race bike, this is not a problem since you are always at WFO and slipping the clutch to keep the RPMs up near the power band.
Here's my website that I haven't touched for 2 years. Don't laugh it was my first and only attempt and creating web content LOL. Eddie's website aka turboed.com.
am i out of line with the ceramic coating or will this be harmless. the seller also included something called a battery eliminator. what your opinion on these.

I haven't heard too much about the battery eliminator, but know they cost $40 on Ebay. There was a discussion on Tony Tice's board about them and figured out they're just large capacitors that hold a charge strong enough to drive the rear brake and blinkers. You don't need the battery to run the headlights, but it's required for the rear brake and signals to work. I never tried one for my street ride, since it was always in track guise.
BTW that bike you bought is from Alamo, CA. That's only 30min from me. If I was in the market for one I would've bought it too. I suffer a thing called stable-itis and have been trying to really stay away from bike purchases these days.
edit- to answer your Q about ceramic coating? Is that like a Jet Hot coating? I don't think it's necessary. It may make the aluminum brittle. I don't know the process so I can't say. I heard the chromeing on the YSR50.com pipes made them brittle than the regular proflow pipe. Personally I wouldn't do it. On my pipes I used a high temp black paint to prevent rusting. TBH I'd use the cash to buy new TT91s or IRC750 tires.

maybe it's due to inexperience or intimidation, but the thought of removing the oil injector off the bike makes me uncomfortable. i don't want to screw anything up do to lack of knowledge or carelessness. i want the bike for street use and the 24mm carb sounds slightly complicated. from reading other forums it been stated that removing the oil injector will give you 500 more rpm. whether this is fact or opinion i do not know.
your right about the tires... even if they aren't showing signs of cracking how good could they be as they are 15 years old. the TT91s seam to be the tire of choice among the YSR crowd, so i'll go that route.
as for the suspension where do you guys put skate board bushings and where would i go to buy them? between the spring and the upper portion of the shock tower? do you recomend this, do you have pictures of this, and is this safe for the street. my concern is that i weigh 194 pounds and don't want my weight to compress the shock to the point that i have no suspension travel.

pix of where I placed the bushings are on my site.
I don't know which site stated you get an extra 500 rpm from removing the oil injector. You might be confusing the tip on removing the lighting coil from the stator for those extra 500 RRRs. Going forward, think about removing that oil injector. What you do get is piece of mind that oil is getting to your engine. You never know when this part will fail.. by then it's too late. Go premix. Ask Barry how to get a hold of Ray. He can help you out if you don't feel comfortable in removing this item.
Since it is your street ride, keep your lighting coil. You'll need it for the lights and keeping your battery charged.
this guy here in my neck of the woods.........."Dr. Ray" as I like refering to him. he is a YSR specialist. Fair and does excellent work. only problem is he is in Ft. Lauderdale which is on the other side of the state for you sir.
but "Dr. Ray" is a great asset to have. he's done almost all of my mods. mostly all the engine work stuff. You'll just have to hunt for a local engine guy in your area that is used to working on the YSR. I have yet to do any "real" mechanical work myself but maybe someday I'll feel more comfortable in doing so. Until, now I'll just keep using Dr. Ray.
I think replacing the carb should be fairly simple. just a matter of tweaking it afterwards. I hear the 20mm carb is best suited for street use. the 24mm carb more for track use. that's what I hear (and read) anyway.
Man, I'm jeoulous. what a nice bike you bought sir. very clean and I'm sure it's in tip top shape.
good luck with it and give me a call. left you a voice message and my email on the PM you sent me.

since I don't have anyone locally in the Tampa area, what is anyones opinion on just plain going to the yamaha dealer? are their hourly rates unreasonable? or do they shy away from installing aftermarket performance parts (from other companies) alltogether.

dealer rates are about $65 to $90 an hour............that's for whatever they do. put on tire, unscrew a bolt, change oil, inflate a tire.............dealer rates are a ripoff. try to find someone in your area that can do work on YSR's.

Yeah I did a craiglist mechanics search for Tampa and couldn't find anything. However I did see a sweet 92 FZR600 for $1500.
One thing nice about living in the Bayarea, you can always find some YSR parts and private mechanics. Some even come to your door.
well the seller is shipping these service manuals this week, so i'm thinking i will be tackling the work myself then. quess we all got to learn sooner or later. hope you guys don't mind answering rookie questions in the future.
barry... the link you sent me for the taillights/turns signals, are they reputable
, is this how you got yours?
keep sending these sites my way. i got plenty of room in my favorites.
well, that link from JTrading I sent you seems to have been operational for some time now.
Anyone else who has used the buying services of of "Andrew" from JTrading please let us know.
I think Andrew imports a whole bunch of YSR/TZM's adn NSR into the states and sells them for a profit. I'm almost sure it's reputable but I'd do my net research firts if I were you.
Remember, my advise costs exactly what you paid for it..............I guess what I'm saying is..........research it for yourself as well until YOU are completely satisfied with the results.
