Ms Peel gears diliman ?

Thinking out loud so others might help think through for me... Got windfall that allows bullet proof TT tranny but what to order?

Interviewing live and late Norton drag racers revealed a common reaction, [after spitting on the floor], "AMC boxes spill their guts on the track when launching with 100 hp", or Just went ya get decent Norton power AMC lets go, so most defaulted to HD trannies. Peel engine could make 90's rwhp w/o boost and at least 50% more on boost. Peel's main feature is handling corner power in wide scope of condition not the power plant per say. She needs to creep up loose steeps and do burn out stunts in parking lots. She needs to float front from 30s to the ton w/o over reving then relax into opens to say 160-70 mph.
Peel has fast change rear sprocket so that ratio can vary for special events but would like a standard tooth count for normal wide scope operation with a side car too. Peel has over 100 lb ft torque predicted and weigh under 350 lbs fully dressed out and 50' less paired down for 'battle'. I don't like to shift much cars or bikes so 6 spd repels me like a peddle bike. Peel could be good to 8000 for record attempts but otherwise lower 7000's max redline to live with.

I figure lowest possible 1st for the creeping and instant tire smoke stunt ease. Top is always 1:1, so leaves middle 2 or 3 gears to decide on. I liked the 850 taller 2nd gear and often used it instead of first on past Peel to save a shift and not just spin in place on standing tarmac launches or loose slope starts. This leaves just one 3rd or an extra 4th gear to consider, I think. This mid gear cluster is my mystery yet more intensive intended usage for Peel, ie: road racing in tights to the wide opens turns like freeway clover left banked stuff from 50s to over the ton. So 1st to 30 mph, 2nd to 90 mph, 3rd ??, 4ht ?? 5th - out of sight. Should hi torque low mass combo like Peel+me shoot for close or wide ratio for this most vital of all mid range envelope? Don't know if below ratio limited to specific offering or can switch among the gear spd counts.

TTI lists their "standard duty' 4 speed 3rd ratios 1.176 : 1, 1.13 : 1, 1.237 : 1

5 speed
wide as 3rd 1.356 : 4th 1 1.144 : 1
Close ratio same, hm"

6 speed
3rd on - 1.418 : 1 1.243 : 1 1.1 : 1

And all of em for Extra HD 5 speed, has lowest 1st listed and kind of close 3rd/4th.
2.438 : 1 1.733 : 1 1.39 : 1 1.144 : 1 1 : 1

For extra suspense wonder how high to gear rear for a land speed test.

Have you got your Norton on the road yet Steve ?

Steve, can I suggest that you put your efforts towards making your standard road going Commando a more reliable bike instead of dreaming of ways to increase power on a 40 year old pushrod design that is virtually guaranteed to need almost everything beefed up at great expense and effort to handle it?

You reported how you broke down and had to return home early on your road trip this summer.

Really, why not buy a 20 year old Japanese 600 for cheap if you need a bike that will vastly outperform your old Commando, get your adrenaline thrills on that instead of scheming of ways to over stress your Norton...........

Is That SPEELT ' dilimea ' with two tees ? . ANYWAY .

This is the Original . :?

Now , if ya chuck a pair of 40 Dellorottos on it , and two inch headers , we could hear it in the next county .

Id want it to run 60 mph in first . Gear changes are a waste of time. in a Quater Mile . SO , Yr gear it for third across the line .

Peel is creeping along to final expenses and last few inventions. Trixie did not let me down in well over a year. LOP trip failed d/t Wes's electrical grimlins but Trixie did crash on each side to bump my knees and elbows but only damage was small nick in rain suit knee that rain cleaned the mud off for me. Peel and I laugh at the suggestion a modern appliance is more capable than a spiffed up Commando.

After you've ridden a rising torque curve to redline its hard to go back to just levelish response curves. Maybe to complete Peel might give up a useless 5th gear for a hand lever reverse gear. Feel the Force PullLLL* PUlLLLL* PULLLLL* PULLLLLLLL* PULLLLLLLLLLLLing....till the front returns to Earth.

Does Peel have a drive belt up front and what is the ratio?

1980 kiest hij definitief voor een carrière als full-prof motorcoureur. Als nevenactiviteit sticht hij weer een eigen bedrijf: Rob Janssen's Racing Research. Met een scala aan eigen producten, zoals superlichte aluminium racewielen, frames, kunststofdelen,versnellingsbakken, lachgas (N2O) installaties en… air shifters!! Al in 1981 wordt voor het eerst de merknaam Easy Shift gebruikt.

Apparently this bike participated in the burnout comp, my heart died a little when I heard that.

Maney 40 mm belt with 36/72 teeth so 2:1 outrigger supported. Not so good on under spun AMC tranny I hear. Past Peel had same primary ratio with 20T sprocket and worked great creeping to dicing to almost 90 in second and not delaying any sports bikes in 4th but 3rd was a drag to get through 90-110, which generally snicked coming out of tights into opens. 3rd was her weakest interval to get passed by 900's up. After 3rd waited though 4th seemed to pull better than 3rd. Somewhat similar to Alan 'Acotrel' report that gearing up his 850 racer just made if quicker much to his surprise. Close ratios are for narrow power bands so think Peel may like wide ratio - more against the grain thinking for getting around faster than expected. I want 150 in some short sections on daily commutes but that won't cut it for the balloon tire pecking order shoot outs in fast tracks, though that's about as fast as anything reaches at Barbers.
Rear sprocket is the other variable. With big diameter granny 1st I get kicker teeth plus more kicker advantage - I think.
