Pretty accurate test. I got about 81 mph out of my bone stock mint '88 about 15 years ago with original, chain, tires, etc. Most don't hit that speed because they are ragged out. Be interesting to test a mint '87. They had faster internal gearing (4th and 5th were higher), and a much larger intake, but were geared slower on the rear sprocket. I always felt it ran out of gearing at the top end for pure top speed, even on a stock motor. They get up to speed very quickly. I think with taller gearing alone, they could hit upper 80's on flat asphalt. Years ago, a guy in Florida took a bone stock '88 zilla with no engine work whatsoever and installed a Dr. Q exhaust system, jetted up the carb (had Dr. Q himself on the phone for tuning tips), trimmed the front fenders, and played with several different sprocket gearing combos. After about 2 days of doing this and posting the GPS results and pics on the quadracer HQ forum, he ended up topping it at over 100mph! I believe he hit 102 or 103 max if I recall, and supposedly the clutch was even slipping a tiny bit at the very top. Motor was a little tired as far as compression. Was running on it's original piston and rings.

100 plus is crazy. This one could use an exhaust system that's about the only thing I'd ever want to do with it cause it's in such great condition.

[@patrickjaegers3110]

@@TheMapleDude1 Yep, I probably wouldn't even change the exhaust unless you decide you want to build a monster. The stock is so nice and quiet for riding it around places where people might complain! Plus, if you get a good left hanging pipe, you have to cut some out of the front left fender for it to clear.

Hell. O that is a Museum artifact how do you find these mint machines im sure you put some wrenching on em ?

[@frederickrach5195]

I forgot to mention. In my previous comment, that was my favorite quad I miss riding that quad. I wish I never would have sold it. They don't make them like that anymore

[@TheMapleDude1]

No they do not.

[@EasyMoneyCrew]

that 500 is so sweet love the videos keep them up!

[@timsternitzky8711]

Thanks man.

[@TheMapleDude1]

We will try!

[@getsomepack]

Beautiful machine I’ve always wanted one!

[@TheMapleDude1]

Thanks I waited a long time to find one.

[@rcuniversespeed9447]

beautiful example!!

[@agib1368]

I had a Honda Trx700xx that would consistently hit 86mph and it was bone stock. 79mph on a vintage 2 stroke of that caliber is insane

[@TheMapleDude1]

I'd love to ride a 700xx. Thanks for watching!

[@apaudorff]

That’s ripping man, and on dirt

[@TheMapleDude1]

Dirt roads is what we got.

[@Infernal_Elf]

Thats some insane speed my Can-Am renegade 800cc 2008 did 77mph or 125kmph with a new belt.

[@TheMapleDude1]

Cool thanks for the information... I like hearing what the modern machines do.

[@frederickrach5195]

I owned one of these quads in 1989 it was a 1988 they have a crank bearing problem so you have to bronze sleve the crank bearing races the way the races are for the crank bearing from Factory they are aluminum they heat up too quick and a steel bearing heats up slow and it starts rattling them and after time you have to bronze those races and that makes a tight seat bronze heats up faster than aluminum and the steel that causes a good tight bearing fit we pressed in the bearing sleeves into the new bored out race at 5000th press the bearing in at 1,1000th and then you're able to get the bearing out without the sleeve coming out for the next bearing change bronze crank bearing race but after that never any other problems and another thing if you add a tooth to the front sprocket and I think there are 12 tooth go to a thirteen that will give you more top end speed but less of a low end going down a tooth on the front sprocket from Factory you can barely hold the front end down I went down a tooth to race with paddles on on Silver Lake sand dune Flats by Lake Michigan and since they are a short race came out real good because the thing leaps out of the hole just got to lean over to bar and keep the front end down

[@TheMapleDude1]

Ok you got a lot of info there... lot of experience... thanks for watching!

[@frederickrach5195]

Thanks for responding to my text I'm not sure I have a lot of knowledge or anything I know a lot was trial and error messed with quads bikes and Buggies for a long time

[@frederickrach5195]

We did All right in finishing

[@frederickrach5195]

Well I'm glad somebody actually understood what I was talking about and appreciated it. Get ahold of me again If you'd like to touch base I can give you my information and we talk. I don't fly my phone on on. The? Phone or something but you guys are doing sweet things and there's so many little tweeks. Just stop white dad and just run and make things run sweet so enjoy it love it. I'm retired for riding that stuff because my 7 surgery done.

[@adriankagyut111]

Fast af boy

[@TheMapleDude1]

Boom

[@WestCoastRoller]

Send the motor out to Dr. Q in CA or Jerry Hall in Phoenix. Look them up they will fix all the 500 engine issues from the factory. One and done.

[@TheMapleDude1]

Thanks it's all.good as of now.

On my 500 i jumped to a 14 tooth and will see 84. But your stock 13 is about right at 80 to 81.

Yeah good point.

I have an 87 quadzilla 1/2 mm over bore trinity chamber Fmf silencer and a Kehin flat slide and I’ve hit 100 mph don’t know how much over that but I have hit triple digets

How do you know you went over a 100 and not know the exact mph?

[@timitbiscuit3620]

That is the top of the mountain right there. But it too much 4-wheeler for myself. I thought they were stock 6 speed. Now your driving around about 15,000 dollars.

[@TheMapleDude1]

It is indeed a 5 speed. I was lucky to find one!

Nice Zillow. Is the 250R back together?

[@TheMapleDude1]

Yes it is. We will get that on a video sometime yet this fall.

Yes some new but also have to look for used.

The clutch is slipping so bad it won’t pull high gear without slipping

[@TheMapleDude1]

Huh? Clutch is good.

[@matthewjohnson2495]

@@TheMapleDude1 If the clutch is good then it needs adjusted cause it’s most definitely slipping. I wouldn’t waist my time commenting if it wasn’t. Most of the Banshees on KZbin is slipping also. A GoPro really pics up the slipping like it’s right in front of me
