I've got a newer (maybe '04) OCC type Schwinn Stingray with the seating tube cut totally from the frame. I don't think this has really effected stability.

What I need to know, though, is what is the largest and best 4 stroke engine I could fit into this thing? I'm not sure exactly how much room I have to work with, but I'd like to think I could fit maybe up to a 125 dirtbike engine in there, albeit a little uncomfortably.

So if you know anything, as I'm new to this, what all should I do/what can I do to make this bike run strong and proper?

Any advice is appreciated. The goal is to go street legal and pull off the highest possible speeds. It'd be great if you guys could tell me how to switch to a disc brake system too. So many questions. ]]> bryanedp9 http://motorbicycling.com/f37/what-can-i-fit-stingray-13111.html my hoot gearbox survival method!! http://motorbicycling.com/f37/my-hoot-gearbox-survival-method-13070.html Wed, 18 Nov 2009 21:31:52 GMT so far my hoot has about 600kms on it, im guessing thats pretty good, im still paranoid it will blow up at any moment but as far as i can see i dont see anything that can go wrong(besides stripping gear teeth, or the clutch etc.) anyways, i experimented with diferent oils and greases, i found that white lithium grease broke down into a liquid and made the clutch slip, i have a few pictures i would like to show you, i greased my gearbox 2 days ago, and this is what it looks like after about 150kms of riding, Attachment 16132 (http://motorbicycling.com/attachments/f37/16132-my-hoot-gearbox-survival-method-dsc04510.jpg) Attachment 16133 (http://motorbicycling.com/attachments/f37/16133-my-hoot-gearbox-survival-method-dsc04511.jpg) Attachment 16136 (http://motorbicycling.com/attachments/f37/16136-my-hoot-gearbox-survival-method-dsc04517.jpg) Attachment 16137 (http://motorbicycling.com/attachments/f37/16137-my-hoot-gearbox-survival-method-dsc04515.jpg) Attachment 16138 (http://motorbicycling.com/attachments/f37/16138-my-hoot-gearbox-survival-method-dsc04518.jpg) as you can see the grease is almost completely off the gears, but i see no visible wear on the teeth at all, they look perfect, so far my hoot has about 600kms on it, im guessing thats pretty good, im still paranoid it will blow up at any moment but as far as i can see i dont see anything that can go wrong(besides stripping gear teeth, or the clutch etc.)

I'm not 100% certain that was it but it looks right. Has anybody heard anything about them? Apparently Spooky Tooth is going to start carrying them. I don't think they're out in the US yet but I was curious if anybody from other parts of the world have encountered them.

Accepted final bids on Q-Matic yesterday!

Scheduled delivery 3 weeks.

Aluminum isn't cheap in the USA!

Thousands and thousands of test miles logged by dealers nationwide.

American labor isn't cheap!

Test riders on the West coast
Test riders on the East coast
Test riders in the South [still warm in many areas]
Test riders in the North [a little colder up there]
Test riders along the Atlantic coast [was only 85 today].
The results are in!
We did it right!

Shipping isn’t cheap!

As hard as we tried, we couldn’t meet the projected MSRP, but only missed by $9.75.
The MSRP is $259.75. No matter how hard we tried to bargain, the American labor force simply wanted paid for their services and quality materials.

The Q-Matic drive was tested on a variety of 4-stroke motors from 35 CCs to 8 HP. It has been tested up hills, against the wind, and with riders from 100 pounds [thanks Ladies] to over 300 pounds. It has and is currently still being tested pulling a trailer in a hilly terrain [Thanks, Bill]. Thanks again Bill for projecting the motorbike as a family friendly form of transportation.

We listened when many requested ease of service, KISS [keep it simple stupid], quality parts, good warranty, silent operation, easily changeable drive ratios, a real working dependable “custom” American made automatic clutch, thin design, adaptability, and maintain backwards compatibility.

The entire system was designed and then machined on CNC equipment in American shops.

Because of design the majority of the power is transmitted from the motor to the rear wheel, and therefore the Q-Matic drive ratios allow better use of the power band.

The production drive ratios will allow the speed of 30 MPH at 6200 RPMs on a 26” bicycle with an average weight rider on a level surface. Considering the ability of the HS or Honda 49 CC 4-strokes to achieve RPMs well above 7500 RPMs, 6200 RPMs is just right for a smooth ride.

Ratios can easily be changed for heavier riders or to compensate for hills.

The Q-Matic and the future Silent Drive II can be attached to most motors with the output to the rear [for frame mount], and 90 degrees downward for rack mount applications [We don’t supply rack mounting systems].

Did I mention the Aluminum? Lots & lots of Aluminum in the Q-Matic drive by EZM.

$259.75 MSRP
EZM dealers can answer your questions, call them!

All orders prior to Dec 15th $249.75

Best order quickly because demand should outpace production for a while.

Have fun, ]]> Quenton Guenther http://motorbicycling.com/f37/ezm-q-matic-production-started-12773.html 80ccmotorboys vendor review, http://motorbicycling.com/f37/80ccmotorboys-vendor-review-12764.html Fri, 06 Nov 2009 15:26:55 GMT so far i have not purchased anything from Rob yet, but his service via email has been great, unlike many other vendors located in china, he seems very friendly and offers great prices, especially on the 4 stroke engine kit, i am heading over today to pick up my 49cc 4 stroke bicycle kit, he has offered me a warranty on the hoot gearbox because of the problems some people have been having, he responds timely and in full English, so its great not to have to worry about getting a response from him, he also offers an array of parts, luckily for me his vendor is very close to where i live so i can get to him and avoid any shipping charges, his prices are tax free(if your not shipping) also he agreed to stay open later for me to accommodate my schedule, another great thing, i will update this when i get my engine kit, i will also post pictures and review how the engine looks before the install, because i get to avoid shipping i will most likely not have to deal with the broken parts and the missing bolts usually associated with getting kits from china, so far he gets a big thumbs up from me, but only time will tell the outcome of this review, i will update this sometime tonight hopefully, so far i have not purchased anything from Rob yet, but his service via email has been great, unlike many other vendors located in china, he seems very friendly and offers great prices, especially on the 4 stroke engine kit, i am heading over today to pick up my 49cc 4 stroke bicycle kit, he has offered me a warranty on the hoot gearbox because of the problems some people have been having, he responds timely and in full English, so its great not to have to worry about getting a response from him, he also offers an array of parts, luckily for me his vendor is very close to where i live so i can get to him and avoid any shipping charges, his prices are tax free(if your not shipping) also he agreed to stay open later for me to accommodate my schedule, another great thing, i will update this when i get my engine kit, i will also post pictures and review how the engine looks before the install, because i get to avoid shipping i will most likely not have to deal with the broken parts and the missing bolts usually associated with getting kits from china, so far he gets a big thumbs up from me, but only time will tell the outcome of this review,

That way I can switch gears throughout the ride and give the engine more ease. 3) I want an engine that can start from a stopped position. 4) I want an engine that is quiet and green. 5) I still want good POWER. But i want something between 50-66 ccs. perferably something close to 66cc 6) I do not want an engine that looks like that honda one.. where it looks like a lawnmower engine. I want the engines that look like all silver that connect in the middle of the bike. Thank you for all your help. Im hoping I can order this engine by the end of the week.
