78 yamaha XS 100 cafe racer

Finally got my parts back that I sent out for paintwork, tail section, gas tank, fender and headlight. It's about 90 % done . Just gotta make a seat pad and relocate the battery into the tail section

If anyone is curious, I am the new owner of this bike. The original owner/builder passed away a while ago. The bike is still in amazing condition. I ride her all the time.

[@thunderbluelex]

@Takumi Fujiwara. Thanks man! I spent about $1600.00 , including the price of the bike, which was $500 .

[@Tony211289]

Nice bike. Wouldn't hurt to out some fork gators on the front, looks a bit skinny with that wheel dominating

[@thunderbluelex]

@corey Renner the bike runs great actually. When running open pipes like this, you have to go up a bit on the jetting. I went one step up on the idol jets and running 150's for my mans. And also have 152's on hand just in case I had to go up one more step. The needles are in the stock location, and I have the needle screws turned out around three and a quarter turns . Now I'm also running open velocity stacks too. And with this setup, this bike runs like a monster. And throttle response right there too. I've tried to tune before, using air filter pods and the bike just never ran quite right. Probably if you were to run air filter pods, you might need a little bit back pressure on the exhaust side of it to kinda even everything out.

[@thunderbluelex]

@ Colin McCafferty. Hey bro. Its a MAC 4 into 1. But I only used the front header. And then put on a 45 degree turn down exhaust tip on the end . Then wrap up in titanium exhaust wrap. Sounds pretty good.

[@riannesalvarita8155]

Bad ass exhaust sound.

[@thunderbluelex]

@derek jent thanks bro! It's a MAC 4 into 1 chrome exhaust . I only use the front header. Then picked up a chrome exhaust tip turn down with a coupler and riveted onto the collector part of the header. then wrapped the exhaust system with titanium exhaust wrap, and that's it. Just to let you know, this thing is really loud on the highway when ripping it lol.

[@thunderbluelex]

@Ross Washington. This is actually the stock tank. The 78 and 79's have these.

[@thunderbluelex]

@vladimir lissoi I've been thinking about it. I do have another XS 1100 that I will be building shortly so I may try it on that bike.

[@thunderbluelex]

awsome!

[@marcelflo2765]

Great Job !

[@thunderbluelex]

sunnykrusty thank you very much!

[@veganvvarrior]

Very nice, except the led's.

[@thunderbluelex]

veganvvarrior haha thanks lol. I hear ya, no more led's lol

[@davidwebster8095]

Hokey ights!

[@sunnykrusty]

Bloody awesome *****

[@thunderbluelex]

@ vegan. Thanx. And yea I know lol. I took them off already lol

[@xzqzq]

Nice. Good that you kept the kicker.... How small a battery could you get away with if you wanted to go kick-start only ?... have you weighed the bike ?

[@northercalibassin8894]

I know this is an old video, but if you read this can you tell me about your seat? I'm building a 78xs750 and want a seat like this. Thank you.

[@cggirl8806]

alright i see the exhaust, online to buy. With your tip, are they left open pipe, or is there any back pressure? I've heard that you can have some running issues without back pressure on these things, or you'll have to re-jet the carbs, etc. Sounds great though and will likely be following your example for the sound. Did you have to do any carb work, or are you having any issues with it running right?

[@TripleHelixed]

Absolutely gorgeous bike! I’m just finishing up my XS400 cafe. What battery are you running?

[@derekjent]

What type of exhaust is on it, or something you had built. Watched your videos and fell in love with the sound..just picked up a 79 I want to bobber and want to go similar exhaust

[@Interworked]

Hey, thunderbluelex, really sick bike here, nice work! I just had a few questions about your bikes: Do you personally build custom bikes for people? If not, do you work at a shop that builds custom cafe racers? And, the last one, what price range are your custom builds similar to this? I'm saving for my first bike that I should be able to afford by next summer, but I'm really enthralled by cafe racers, Yamaha especially. Also, could I get your opinion on an issue I'm having: Do you think a cafe racer would be a better choice as my first bike, or would a sport bike be the better choice? I initially gravitate towards the style of cafe racers, but I'm also considering getting a sport bike as my first bike. This is mainly because of the maintenance/upkeep issue with cafe racers: I know if a particular part breaks, it can be really hard to find a replacement, especially with custom builds. And because I'll be a beginner, I'll be more concerned with learning to ride on my bike, than constantly making sure I have potential replacements for all the parts on the bike, you know? Not that the " mechanic" aspect won't come with time, but, as a beginner, mainly I'll be looking for riding thrill. With a sport bike, maintenance and parts are just a drive away to the local dealer, so there's potentially a lot less hassle on my end. And, if I want to learn on the bike and start riding without anxiety about parts holding up, a sport bike seems like a more practical choice. I don't know, maybe that's why a lot of custom cafe racers are side project bikes. Maybe the cafe racer parts availability issue is just a myth, I'm not sure.. But anyway, from your expertise with cafes, what do you think about the whole situation, man??

[@markcoolidge7399]

Love the seat/tank combo. Any info on where to find those components would be greatly appreciated. I'm building an 81...gsxr 600 front and rear, mono shock, fuel injection, 1196 big bore, possibly turbo. Been looking for the 2H7-1100-00-05 tank, but can't find one anywhere.

[@thunderbluelex]

Mark Coolidge awsome! well the tank is stock, the tail I found on Craigslist. but you might find it on dime city cycles, and they have a big variety too. vortex clip on's yamaha virago 535 head light .

[@Daniel-qu5jt]

How much money and time would you say went into creating such a beautiful bike?

[@thunderbluelex]

Daniel Yi probably about 1600 bucks, including the price of the bike, ($500) .

[@mdggruber]

What oil cooler are you running??

[@concernedcitizen1320]

Dude killer bike, what did you do to the engine and transmission? My bike is slipping 2nd gear, I have the new gear and transmission gear shaft. I have some leaks that I’d like to fix, and I don’t have an oil cooler on it. Let me know if you want to work on my bike I’ll pay you . Your bike is very responsive. Great job!!!!!!

[@CuchulainnGael]

What type of exhaust do you have on this bike? It sounds great, and I'm in the market for a new pipe for my XS11.

[@Ilovejessica123321]

Mac header

[@scotts5571]

What parts did you paint yourself and what kind of paint did you use?

[@imceuropeb.v.jonker6826]

Hi there, this bike inspired me to start on my '82 1100xs. can you let me know which clip ons have been used here? also looking for a '78 style gas tank.....thx!!

[@moisesramirez7542]

+IMC Europe B.V. Jonker hi there i have a complete 1978 xs1100 w/clean title if interested non running from sitting so long good compression though just needs a little love

[@danielthomas195]

What size tires

[@domingomeza397]

Hi, are you using the original front wheel (19") or different size? thanks

[@thunderbluelex]

Domingo Meza yes, the front wheel is stock . I just took both wheels off and repainted them , then wire wheeled the edge of the spokes.

[@thunderbluelex]

***** why thank you very much! I spent about $1600.00 That's including the price of the bike , which I bought for $500. And I have another one also which is a 79 XS 1100 that I will be building shortly. I post most my work on IG. Just look for "rockstarracer13"

[@Ilovejessica123321]

What kind of tank? Is it a custom job?

[@agamurtuza8963]

Please do something else on exhaust. Beauty she is.

[@tyrbjrn487]

Fuck off guy.

[@derekjent]

Nevermind just saw it down a few posts

[@demirpurisic277]

Hey, wondering if this is still for sale?

[@scottwaldick6760]

What did you use as a filter for air stacks? They look good.

[@thunderbluelex]

Scott Waldick thanks ! nothing actually lol. those are the original velocity stacks the that were in the air box. if there're in good enough shape , use them.

[@scottwaldick6760]

thunderbluelex mine are in good shape. Did you cover the ends with any type of screen

[@thunderbluelex]

Scott Waldick yeah I actually I did! sorry, forgot to mention that before.

[@scotts5571]

What parts did you paint yourself and what kind of paint did you use?

[@ayanaali546]

where did you get the seat pan?

[@thunderbluelex]

Ayana Wright I actually found it off of craigslist , for like 69 bucks lol. but I think dime city cycles may have it . and they have a lot of different caferacer cowls to choose from too.

[@scottwaldick6760]

Could you comment on your jetting? Main, pilot? Any change in air jet?

[@thunderbluelex]

Scott Waldick. i believe, mains 150 or 152. idle jets , 1 step up from stock. I think 45.5. air idle srew, started with 3 turns out , then went from there in tuning. had 3 of these bikes, and each one was a little different from each other.

[@scottwaldick6760]

thanks for the info!

[@thunderbluelex]

Scott Waldick anytime!

[@scottwaldick6760]

You may have already answered this but where did you get you seat cowl? It looks great!

[@thunderbluelex]

Scott Waldick I found it on Craigslist lol . but dime city cycles has a lot of them, different styles too. also you can see more of my bike on my Instagram page - rockstarracer13.

[@brentjgordon]

dont just stand there.....ride it

[@thunderbluelex]

xzqzq hey bro. Its a kicker a 77 kz 1000 actually. Just have to tweak it to clear the rear brake pedal arm . I'm using a lithium ion battery from "Battery Tender. There a lot smaller then the stock batteries and plenty of power for what you to do. And I have had a chance to weigh the bike yet but it's probably still around 600 or so. She's a heavy bitch lol

[@user-zu2hk7mw4b]

Колеса от ижа чтоль ? :D

[@arturotejeda513]
