Does anybody sell just the 4-stroke mounting kit?

Have you checked out Staton? Their kits are a little more than others but are very high quality. I bought my R/S chain drive kit on ebay. With the Bing and ebates cashback I saved over $100 from the website price. Bing cashback was a little higher when I bought mine than it is now. They sell kits with both those engines.

Staton-Inc motorized bicycles, bike kits & gear drive kits.

Hello Finfan, well I do not know what this "word" (AFAIK) means! BUT I do know a bunch about Motor Bicycles, absolutely know EZM, and am familiar with several of the currently popular 4-strokes, so here is a little about them.

Honda GX31, GX35, small, with cent clutch on the short crank, the versions I have seen use 76mm clutch, and the hub is installed kinda "recessed" into the crankcase.

Robin Subaru 35cc uses a similar clutch, flush with the mounting flange also. Titan, Hoot Chain-drive, and Grube 4G all have similar 76MM clutch, again pretty flush with an extended engine case.

These engines will work on the friction, and other systems that use the 78mm clutch bells, and are not well-suited to the better in-frame systems.

Typical Hoot has 15.1MM turned down crankshaft with 3/16 key-way. Grube gear drive boxes have 16mm or 5/8 nominal crankshaft sticking out the side, less engine case on the right side (about 1 inch). These have a key way that is a little smaller than 3/16.

Honda GX50 5/8 shaft, 3/16 key way, easy deal, bad carb hookup. I and WE at EZM use 15.1mm, and 5/8 shaft that stick out the side of the engine. Easy deal, works well, no worries.

HF Greyhound we have already done, no big deal, a bolt-on for the Q-Matic, or Silent Power Drives.

We are looking into adapters for the "challenged" crankshaft models.

EZM does not use the little on-board weed eater type clutches, we made our own system (Silent Power) and use Max Torque (Q-Matic) special series clutches, no Chinese weed eaters to power us.

The Q-Matic is now availble as a stand-alone product, to be used on whatever the customer dreams up.

This should answer some of your questions?

AFAIK = as far as I know

Fin,
I don't know if vaporware is quite right but Dan and I will be puting it through it's rigors before it is brought to market.
FireBelly does sell custom aluminum engine mounts, "standard" engine mounts are $57 and custom are $77 made to fit virtually any motor in virtually any frame. Price on website is wrong, I thought my wife edited that error, so thanks for bringing it to my attn.!

I do like inobtanium! No offense taken Fin. I was having fun w/ it! Be well! Evan.

That's what I love about this forum, ask and you will get answers!

I've looked at the Staton kits but they don't seem to have anything for a simple in frame mount.

Thanks for the info Mike! You may get some PM's as I try to work out the details of this plan. Progress of course will mainly depend on my employment status and income. I think I may want to quiz you on what is involved in fabbing a converter for one of those "challenged" engines.

Thanks!

Why are you bent on in-frame? The Staton kit was very easy to install. I guarantee an in-frame kit won't be easier. I like my engine behind me. Maybe other people don't like the engine in the back.

What is the law in AZ Fin? 20 MPH and under 35cc? Have been thinking of making a kit with 35s

As a consumer, what would you like to see in one? I was thinking an option of belt drive but that is turning in to a bit of a pain. Do really like the looks and sound of a belt drive though

Hi FinFan,

2 years on my EZ bike, not even a loose bolt!

On my prototype... zero problems.

Over 2600 miles on one and approx 1200 on the other.

4-stroke is the way to go, and staying legal is a good idea. Easy take-off [no pedling], high MPG, great cruising speed, great sound, and far less maintanence.

Biggest problem is to remember to check the gas [it uses so little, it is easy to forget].


Have fun,

The 4s really are nice. More umph and less vibes. Not saying I don't love the ChinaGirls, I do.

Been shopping for under 48cc. Will let ya know. Really wish the Greyhounds came that small. sweet lil runners.

I hit 3500 miles on my odo today...
I am quite pleased with that

That is awesome Bill. ..and pulling the trailer

Hi Finfan, one of our guys mounted that RS on a Silent Power, I did not get to ride that, as it was in Michigan. I have, however ridden to RS 35's a GEBE, and a BMP (I think) friction drive.

The GEBE was brand new, not broke in, and was less power than the friction, BUT, even at my 300 lbs, it pulled me, and would run at least 25. I did not get a chance to ride that GEBE much, because its owner had put airless tires on it, and it rolled a rear tire right off the rim in my court, so I was afraid to ride the second bike much, did not want to damage it. The friction bike was broke in, and ran ok, no match for my bike (we were trading off bikes), but who would expect it to be?

The adapter for RS 35 is definately do-able, tho I do not have a test engine. If I ran across one really cheap I would consider building it out into a small frame bike myself (like my 65 StingRay).

keep in touch, let me know if I can help,

Mike

The EHO35 looks cool. If I am not mistaken, HappyValley had a bunch of them.
