unfortunately it may be a week sorry bike and engines are in my friends garage while we wait on shipping and until Saturday we work opposite schedules he works while i sleep vise versa but on Saturday i defiantly can if no other user beats me to it .
 
I personally have an HS49 and a HF79, and can tell you the 79 is quite a bit larger. It's got an extra 2" in width, but it's about that less in height.

My HF79 with AGK tranny and cover measures about 12" on the nose. A 99 with Q-matic would be perhaps a half inch less, CVT more.
 
After looking at all the clearance I have between the HS/ Q-matic and the wide pedal setup I mentioned earlier There should be plenty of room for a 99/ Q-matic.
Who knows, I just may end up building another MB outta my Trek 7000 with a 99 and an AGK CVT...

Edit: If I do that, I will be out of pedal power only bikes! Hmmmm.....

Neat thing about the 79/99 is that it can be mounted up rather high, above the crank circle. Maybe all that's needed is some pedal extensions.

I was putting my 79 in a GreenLine semi-stretch, the stock cranks cleared under the engine.

sorry their not the best ended up mounting it before i could get a side pic maybe someone will help out and post something better.wee.

(wife helped out with pic . )
 
Thank you very much for your efforts! In the top photo the 99cc seems to look smaller than the 49cc.
In the bottom photo the air cleaner alone for the 99cc looks nearly the same size as the whole 49cc. Those 99cc engines really are alot smaller than I had imagined they would be.

Oh my bad, I see the sticker now. They are both 49cc.... ;)

if you have any pics that d be greatly appreciated

i was just trying some pics out to make it so everyone can see the difference in size i know i was rather shocked when i put them up against each other .

i will ultimately have to with some pedal extenders my feet can hit the pedals and turn them over but at a very awkward angle .
 
OK, AF...

I can do that.

IMO... :-)

the prob with widened pedal cranks is that u end up paddling like a duck!

Not really so bad if all you are doing is getting momentum to start a motor, but really stoopid if you are actually trying to pedal somewhere when it breaks, runs out of gas, or the tax collector is there.

For my cruiser bike/comfort bike style, I'm hoping to re-fab a frame more or less in a 'townie' style, to get any wide motor back towards the drive tire (and a short power chain run), and standard pedal width forward of the motor, where they would most likely function as forward mounted pegs...
