Yamaha TZ250 Grand Prix Racer - Rebuild time lapse

Riksfjord Racing - The Yamaha TZ 250 T is a full factory racing bike used in GP year 1987. Aluminum deltabox frame with monoshock suspension. Parallel twin, two stroke engine.Two 35mm flat slide Mikuni rejetted carburators, rearward facing. Reed valves with 6 petals. Electrically driven power valves. Exhaust leaving through the front of the cylinder bank. Assembly is done after a total overhaul. Replaced bearings, crankshaft, clutch and piston. Made with sound of Yamaha racing. Motorcycle build. This is a rebuild after teardown video, not a how to.

Back in the 80s I ran a TZ350 G top end, carbs, expansions, grafted on an RD350 bottom end on the road, the whole lot new including carbs was bought for £200! Yes it had a kick start and a wet clutch. The clutch had beefy springs and a very hard life, the engine actually kicked up and often would tickover. I monoshocked the frame made my own electronic ignition and water pump and fitted TZ body work in Kenny Roberts Yellow and Black....... Fast? urm yea nuts would pass almost anything and on any twisty road it was mental, it ran Castrol R, well had to be done ......this sound track ......memories.........made the commute to work truly epic, sold it to a guy in Madley. If your out there and still alive lol message me.

You sir are the conductor, love the orchestra! Brings back so many memories of my good old days. ☝️

[@Fabformcatering]

That’s a beauty. Had an AS3, YR5, RD 350B and a RD350LC. Love the Yamaha, those colours are fab.

[@stevefowler2112]

Awesome...brings back so many memories...I grew up on two wheelers and earned two AMA Expert Licenses in the early 70's in 125cc and 250cc Motocross and was about to hang up my racing boots in '75 when I was a Sr. in H.S. and prepare for Engineering College when my sponsor (Island Yamaha in Merritt Island, Fl.) asked me if I'd like to do some practice laps on a TZ-250 (B) and depending on how it went possibly campaign it for half a season in '75. We went to Sebring and I was one of two other riders to run practice laps and I had the fastest laps (the other riders had road race experience and I did not) so I got a free ride for several races in '75...including Daytona, where I ran in 3 different prelim races and placed 5th in the amateur 250cc final...and had the distinct privilege of being passed by a certain Mr. Roberts on his TZ-700/750 during open practice.

I think it's about time you received a like for your 😳 And a 👏🏼👏🏼👏🏼👏🏼👏🏼👌🏼😇 Well done 👍🏼 and I love that you love ❤️ 2 strokes 👌🏼😇😇😇😇😇

[@charliea3723]

Yellow crocs in the background mechanical skills and best sountrack ever wowwwww you guys rock

[@dinxsy8069]

Some people pick the worst music as an overlay on videos, i don't think a better choice could have been made on this video. Great.

[@brandongardner3073]

Haha yeah was awesome

[@FIVE-0-APOCALYPTO]

It's about fucking time.

[@Suffolktrueblue78]

Stunning absolutely brilliant, well done you clever buggers 😀 2 stroke Yamaha's SIMPLES 🏍

[@robskywalker1969]

the best 11 min I have ever had on KZbin

[@quantumquestthebillionaire1527]

Then you have not met Filthy Frank or Whitney Wisconsin to name but a few?????

[@thebear6529]

id pay good money just to watch these guys work!! godbless

[@VMX42AUS]

Love the yellow crocs👌🏼👌🏼👌🏼

[@minisla]

Probably the most enjoyable video I have ever watched. Well done 👍

[@johncarlson8029]

As far as i am concerned there is no better hobby or personal satisfaction on this earth. I wished i lived next door as we would spend alot of time together

[@unionrdr]

Oogah, baby! How I miss watching Kenny Roberts on these old factory Yamaha's! And knee-draggin' in general. Dang, getting old sucks. Beautiful race bike resto!

[@1keykneedeep]

Clearly, you gentlemen know what the heck your doing and highly skilled I might ad. Top shelf gents

[@donniebaker5984]

your right on with engines like these with only 3 moving parts they become quite complicated an extremely high technical Marvels that are internally supercharged making boost when they come on the pipe but it wasn't until Kenny Roberts riding for Yamaha showed up with two crankshaft geared together was not one not two not three but four individual YZ125 cylinders and heads loaded on top of those two crankshaft gear together for a full displacement at 500cc was making 400 horsepower per liter

[@gangoffour6690]

Great video guys. Big 2 stroke fan. Remembering the great days of 2 stroke race bikes, 2 stroke street bikes also.

[@2stroke4me]

Finally a video with the perfect soundtrack! Enjoyed it very much :-)

[@tinymotogarage]

Perfect soundtrack and beautiful work - nice!

[@silentrider4372]

a satisfaction that you can only get from build 1/1 scale "model kit" gp monster . .i really enjoyed this

[@darrellroeters4951]

Total assembly, nice work filming.

[@mudylafeet]

Excellent video and soundtrack/song ;)

[@wheelie63]

one cannot properly appreciate the hell going on in there when it is rippin' around the track until you see it from the inside, very well done video indeed...............wb

[@gp3yt]

Best soundtrack....E-V-E-R. This is an A-List of Iconic Technology - Deltabox (what a work of art/sculpture that perimeter frame), Yamaha Power Valve System (YPVS)...and @ 7:57-8:05 (proof that Gold Chains are still in fashion) AWESOME re-build. Thanks so much for sharing w us!!

[@bil2kil]

Dudes in the 80s and 90s had the creme de la creme ! best bikes ever the 2 stroke era

[@rick1622]

BEST TOYS EVER i love the smell of two stroke in the morning....

[@alexgolovchenko3791]

Love those two strokes. Lots of folks don't realize how much horsepower they produce. Ok, they're down on torque, so what. When you're on the back straight in top gear pushing past 12,000 r.p.m. at 150 m.p.h.+ with only 250 c.c., that's really something!😎

[@cbrmotardizzato]

Guys you work like a pro, thanks to share with us!

[@CleytonFernandoEugenio]

Cara que vídeo incrível. Muito top ver a moto toda em pedaços e sendo montada aos poucos. Ótimo vídeo.

[@tomwilliams4885]

Entranced. Major talent on display.

[@fw1421]

Two stroke bikes were so amazingly simple compared to the computer controlled monsters we have today. Bring back the two stroke 500’s!

[@robertrishel3685]

Simply one of THE greatest motorcycles ever made! This is a gorgeous example!!! Utter perfection😍😍😍😍 and in the ultimate colours/livery!!!!

[@pauljenkins2501]

Thank you for a fantastic video, with a fantastic sound track.....

[@Vicarium]

I just found the best video ever posted to KZbin.

[@luccianodeive6605]

Muy buen vídeo, que fácil y rápido nos hacen ver el montaje de esta preciosa Yamaha.

[@MegaPoxie]

Nice attention to detail, right down to the matching yellow Crocks! (shoes)

[@anguskangus8222]

Great video ! beautiful machines.

[@thiagorodrigues2189]

Congratulations! Beautiful Job! = )

[@FIVE-0-APOCALYPTO]

beautiful piece of engineering

[@mauriceclemens3286]

I remember back when the water cooled 250’s first came out I was at Barney’s Cycle Sales in St Petersburg Fla getting some parts for a Yamaha R5 I had and one of the sales guys that worked there had dropped his 350 racer and needed a new radiator. He showed me the radiator,and the box it came in weighed more than the radiator did. It must have been magnesium because it weighed nothing! These bikes are amazing. Too bad Yamaha doesn’t make them any more.

[@emmams5]

Not too sure about your PPE gear but the build was a thing of beauty, top marks.

[@benkenobi292]

Reminded me of Nick Ienatsch and his 250 back in the day

[@Farus2007]

O zelo na montagem chega dá prazer em assistir, perfeito! Melhor do que isso só os mecânicos japoneses da própria Yamaha. Parabéns!

[@droceretik]

Você assistiu a mecânica japonesa pessoalmente?

[@alanthevan]

Brilliant. Lovely job.

[@Fastarp]

The best youtube video ever!

[@suzukimethracer1403]

love the safety shoes

[@Surestick88]

@10:38 #racingcrocs I like the effort to colour-match footwear to the bike's traditional Yamaha livery. ;-)

[@motociclistaveterano8480]

But what a beautiful thing I was speechless, this bike is in my dreams.

[@user-oy8td8vt5o]

Excellent!!! Good job!!!👏👏👏

[@leecoomber3877]

Beautiful bit of kit. X magnifico x.

[@peterlovett5841]

Go on - admit that you had some bits left over when done! Interesting video - thanks for posting.

[@johncarlson8029]

Excellent production we would see each other in a mirror!.🏍

[@oniyukiyasu8513]

Sir, you're a genius for using the best background music for the video. I ride Yamaha TZM 150, done some porting too.

[@phongnguyen007]

And what your gain after done it, have a tzm 150 and 1 Kr 150 kips

[@vinibali]

awesome job!

[@abnormaltexan]

I attended MMI in Phoenix back in 2001-02 and the Yamaha class had a TZ250 that Yamaha had given the school. It was a complete and running bike.....well, until one of the Yamaha instructors kept ripping it up and down deer valley road on the back wheel!! So the bike was retired to just being on display in. The classroom and to make sure no one would be tempted to take it for a ride again, administration made him take off the carbs and let admin have them. So the carbs were kept locked up in an office! LoL! It was a cool bike though!

[@patriciabadeau5600]

THE ENGINE WOULD LOOK NICE "VAPOR BLASTED". AND IT WOULDNT HURT IN IN ANY WAY. STILL, NICE JOB. I LIKE THE 70'S RACE BIKES, THEY DIDNT HAVE THE SHARP LINES LIKE TODAYS RACE BIKES DO.

[@idiot-983]

Love the Music !

[@panchotigveien]

Amazing Job 😍🔥

[@KayakWildCamping]

What a nice piece of machinery. Atb/Layjay

[@ericlarson63]

GREAT video! Motorcycle transmissions always "scared" me, I would work on the top end of my different 2 stroke dirt bikes but I was scared to death of the transmissions! Afraid of losing a part or not putting it all back together correctly.

[@lorenzofrusteri9353]

This is mesmerizing.

[@leonelleguizamon5637]

really nice video

[@fabricioleonardoGRB]

Espetácular, maravilhoso, fantástico.

[@BillyRillkratz]

super cool

[@Timinator62]

Thanks for NOT having some EuroTrash Electro Dance Music for the background sounds.

[@Ed.BR157]

Great vid enjoyed it

[@alexbastenholt1101]

Love the background music

[@droceretik]

Can't win. Most of the time people complain about the music and want engine sounds. They put in engine sounds and someone complains about the annoying sounds. Fuck off pigeon brain.

[@gennosukenokoga]

great build...

[@MrClaushk]

What a nice build :-)

[@sopadegaivota]

Amazing!!

Good work!!!!!!!!!

[@supertedogpriken]

This is amazing good work. wish i had a garage like that and bikes like that. Loved the video, especially when i saw the Norwegian flag :) Helt fantastisk bra jobbet med den yamahaen. Helt utrolig å tenke på at i lille Norge så finnes det perler som denne og dem andre dere hadde i garasjen. Er så lett å bare tenke at det er bare gamle Tempoer som bllir bygget opp her til lands. Ble skikkelig misunnelig på den dynobenken deres da. skulle så ha hatt en sån en til å fått finjustert mine sykler på. Å igjenn: nydelig arbeid med yamahaen :)

[@bmikos]

Beautiful!!!!

[@CumminsDslPwr]

Nice to watch some guys who are Pro's, and know the bike they are working on like the back of their hand. I haven't had one of those apart since the 80's, LOL. What were you using in place of Yamabond on the cases btw? Great job, needless to say.

[@fpreston9527]

Thanks for sharing

[@Ghostdog4]

"Back In The Day" it always impressed me when a TZ250 would win races against liter bikes at the track. Kocinski would show up and embarrass all of us locals

[@Jungleland33]

Beautiful. You need a guard for the chain and rear sprocket though.

[@linus2910]

You are right, we forgot the shark fin!

[@schirmeyerb]

linus yes we have seen ..45 years ago...near PARIS...monlhery..autodrome......to have the pilote sex...cut in 2 parts...the seat was also cut
