There are pictures in the photo section under "Joe in St Louis" or cut & paste... Message - Old Mini Bikes Photo Gallery Not sure what year or model. The clutch in a newer style, not the original. Engine is an 8hp B&S. It's not fast (25 mph?) but it will climb a tree. I don't have any...

If you get the chance, please post some pics of that 2-speed trans disassembled. I'd like to see how they did that-engage one sprocket while letting the other free wheel. I presume it isn't a shift-on-the-fly set up; more like a high/low range. Joe in St Louis Tote Gote

Parting out a Norton? Please tell me more! I have 2 ('71 750 & '75 850) and am a member of a local Norton club. What do you want to move out of your garage? Thanks, Joe in St Louis

AC was commonly used on motorcycles & scooters to power head lights. My old Vespa ('63) used AC to power the lights. They would get brighter as the revs came up. I've also had a '61 Norton once that converted the AC to DC with a bridge rectifier, but it had no voltage regulator. If the amperage...

CaliJeff nailed it! The yellow one is a 1970 Commando "Fastback". The tank, seat, and tailpiece were featured on the original Commandos sold in 1968. The more familiar Roadster model was not offered until mid-'69 (Named the S model), and was fitted with dual high pipes going down the L/H side of...

Thanks for the correction - I never noticed! Joe in St Louis

No, not Triumph nor Honda. Good Try! Hint #2: This marque won the first Isle of Man TT in 1907, ridden by Rem Fowler at an average speed of 36.22 MPH. No fair Googling! Joe in St Louis

...and took some photos of the Ol' Goat in my garage with his digital camera. 20 pts for anyone who can identify the yellow bike in the background. Hint: same brand bike on the stand to the right.

Good discussion here-thanks for the input. Minidrag, your point about a scratch in the cylinder or taper certainly would support what I'm seeing with the weak compression. I might have to pull the head to take a look. I do have quite a lot of experience with ignition timing, setting up degree...

Yes, when you add up the flywheel, crankshaft, and the Comet series 40 clutch, there is quite a bit of rotating mass. I can see where the mass thing is important for drag racing/acceleration, but it shouldn't have any effect on torque. Take a look at tractor design - huge rotating flywheels to...

I've done a little more research. I contacted the manufacturer of Comet T/Cs & had them send me some tech data on the series 40. There design incorporates a cam on the driven pulley, which is for torque sensing. When extra load is encountered the cam combines with the spring that squeezes the...

Here is a link to what I have. http://www.hoffcocometstore.com/cart.php?m=product_detail&p=244

Although I've only ridden my Goat a few times, it's obvious that the overall drive ratio needs some modification. It has a (presumably) 7 hp Briggs, a (presumably) series 40 Comet Torque Converter, and two jack shafts back to the rear wheel. The Comet site says that a series 40 has a range...

I've seen the Torque Converters used on Mini Bikes, scooters, go carts, etc for a long time, but I never really gave too much thought about their operation until recently. I understand the general idea - as engine speed goes up the clutch sheaves squeeze together and the driven pulley spreads...

Yellowhand - I believe Harbor Freight now sells a leak-down tester kit for around $35 - $40. Here is a link to a do-it-yourself build article... http://www.xs11.com/tips/misc/misc3.shtml The Ol' Goat is looking pretty good, and I'm having some fun working on it. Spent some time...

Thanks for the link, Josh. I took those numbers to the parts manual page at B & S site; Model 170702. The third & fourth digit verifies that the shroud came from a vertical crankshaft engine, which was 17 Cu. In (1st two digits). By changing the 3rd & 4th digits from 07 to 04, I found a parts...

I pulled the engine out of my Goat yesterday to take care of some issues - throttle linkage, belt tension, clean-up, ect. I was curious about the condition of the valves/rings because it doesn't seem to have a whole lot of compression. I have a leak-down tester so I thought I'd give it a try...

Yesterday I spent some time working on my Tote Goat. It has a big older style Briggs, but I'm not sure of the hp - the shroud has a decal stating it's 7 hp but the decal is up side down, which makes me believe the shroud/recoil came from a vert. crankshaft motor. The model & serial #s are...
