yamaha yz490,yfz450,3 wheeler.

[leevarnado]

heres the deal.im getting a 1986 yz490 dirtbike from this kid( he's to light in the arse to kick it over)the kids brother has a 2006 yfz450 with a bad engine(really big hole in it).my question is.if you were me and wanted to convert one of them into a 3 wheeler,which way would you go about it.

[cr480r]

you would be so much better off in many ways by starting with a trike frame...

[leevarnado]

dont have a tri z frame.

[cr480r]

its worth getting one... The YZ frame will have the head tube too high and have too much rake to make a decent handling trike..

[SYKO]

dude theres a roller in the clasifeds for 100 or lonesometri-z has a pile of complete rollers fixing to go on the block

[Yamatrike400]

The 490 would be easier, a rebuilt 450 would be a much better engine.

[leevarnado]

well just got off the phone with both of the guys.its gonna cost nadda for the 450 and 490.wheeling and dealing,lol.but the sad thing is,im trading my 200x for the 450.i know guys,but its for a better cause.

[TexFest]

Are you getting a complete yfz450 or just the motor?

[leevarnado]

im getting the complete yz490 that has a good running engine and complete yfz450 with a bad engine.

[cr480r]

I would leave the YFZ as a quad or part it out.. and use the 490 engine for the trike... a 490 fits in a Tri-z frame like it was meant to be..

[Bryan Raffa]

you will have to make motor mounts and a sparkplug wrench for the 490

[leevarnado]

i picked up the 450 and 490 yesterday.so the build starts.im going to put the 490 in the yfz frame for now,then i will eventually convert the quad into a trike.

[leevarnado]

well today i pulled the engine from the yz.the way this engine fits under the yfz its like it was meant to be under there.minor mods required.the hardest thing so far is getting the pipe to fit up right.got a question.will it hurt the pipe performance if i bend it a lilttle .here's a couple new pics.

[fabiodriven]

Holy crap, man! Now that's what I call progress!

At this rate you should have that extra wheel lopped off by, ahhh, let's say 4 am eastern...

[leevarnado]

lol,lots of work left.still have to gusset the frame.and yes a wheel will be lopped off,lol.

[factoryX]

I like it with the qaud frame...lol just leave it like that, nice stock/sleeper look...

[leevarnado]

forgot to mention,gonna be doing alot of push starting until i find a way to use the kicker.

[factoryX]

can't you the plastics off to start the bike and simply put them back on?

[Custom200]

That looks sick. Gonna turn some heads with a huge screaming 2 smoker. There

was guy on youtube that had a 490 in a blaster but I can't find the video

anymore. Anyone else see this before?

[leevarnado]

ok so i took it for a test run.its crazy fast.who makes a really really good helmet.

[Yamada]

I can add you one with paint if you have somes actions pictures...

[leevarnado]

its not a trike yet(waiting for funds).i will get action pictures this weekend.

[fabiodriven]

Friggin things riding already? Jiminy cricket!

Oh, no shite eh? We'll do some riding for sure. You get that thing all together and I'll be forced to get my clunker going! Got a good group up here from the boards...

[factoryX]

the trike will be cool but are you really going to cut up a 450 qaud?

[350Xhilaration]

While you're searching for a good helmet...find some fireproof pants...your right leg is gonna be SMOKIN'!!!

Very fast progress.

I haven't even been able to find time to put a clutch in my Banshee since Dec 2006.

[leevarnado]

the trike will be cool but are you really going to cut up a 450 qaud?

if i can find a cheap yfz450 engine,than no im not going to cut up the quad frame.

[leevarnado]

[fabiodriven]

Skrew the quad, cut it up!!!!!!!:TrikesOwn

[The Goat]

what about using the 450 dirtbike conversion method like mr atc

I betcha that bike hauls three loads of ASS

[cr480r]

So I havent heard any mention of teeth rattling vibration.. Have you ridden it yet?

[leevarnado]

So I havent heard any mention of teeth rattling vibration.. Have you ridden it yet?

yeah it vibrates like hell,lol.but sure is fast.

[leevarnado]

i might need to get a custom pipe made,so that i can get the rear fenders to seat properly and not melt.who can make me a custom pipe??

[Tecate250]

Sweet bike. Cut it up. lol

[leevarnado]

today the throttle screw came in,freaking $20 for one screw.painted the engine and and replaced the engine mounting bolts.this is what i used this time and so far the bolts hasn't rattled loose.3/8 hex cap screw/washer,washer,lock washer/nut/lock nut.

[MonroeMike]

Looks fast just sitting there.

[MyMistress86R]

Wow...lol...just friggin wow! As I sat here going thru this thread, I went from 'oh god' to 'holy crap'. That was fast and looks great. Mad props to you sir.

[rdlsz24]

Sweet nice work. That 450 is in better shape that I would have guessed going by the toasted engine pics in one of your other threads.

Rob

yeah that engine was totaled ,guy was wto when the engine locked up.also said that he bought the bike new and rode it very little for 3 months.i was like wow man,that sucks.7k for a bike you only get to ride for 30-50 hours.i think the best thing about this project was that i spent less than $100 on it.and now im going to sell it and buy a mint tecate 3 r 4.lol.

[Bryan Raffa]

so you not turning it into a 3 wheeler? your gonna sell it and buy one..

[leevarnado]

so you not turning it into a 3 wheeler? your gonna sell it and buy one..

i put it up on craigslist if no one will give me at least 3k for then yeah ima cut a wheel off of it.i found a mint condition tecate 3 and 4 for 2500 a piece,if i can sell the 490 ima get one of those.that tecate 3 would look better in my backyard than a chopped up quad.

[factoryX]

good luck...I almost bought a 07 yfz450 with 12 hours on it for $3000, he also had a 06 with about 40 hours on it for $3000....

[200x Basket]

your fron mount vibrates loose becuase of the design. the bottom needs to be welded or trianglulated to another spot.

nice looking conversion!!

[fabiodriven]

I am really impressed by the speed and (from the looks of it) decent quality of this build. That engine looks like it belongs in there. Nice job.

[Bryan Raffa]

moved you over to the quad forum, till you decide to cut it up.

[super90]

If you cut it up would you want to sell any parts off the front end? I wouldnt even cut it up, it will handle much better in the quad frame and it looks good. Just saying, you wont get 3000 out of any sane buyer. I bought a mint 04 yfz for 2800.

[xman23]

yeah man dont cut it up! no way some one will buy it for 3000 I just bought my 06 for 3200 with very low hours, keep it and ride it its bout the best handling atv your gonna get
