TTI don't fit cradle - whot do ya do?

6061 TS 5/16" plate cradle material with excess areas crying for my drilling. Questionable reseal value of Peels one in a row TTI d/t the HD side car race shell and guts, custom granny 1st and wide as possible only 3 more ratios. Don't expect to use 1st to launch when matters. I don't expect any return on Peel investment but for expressions of others firm understanding of m/c behavior blown away. After being made aware of Burt Munore I just ask, what would he do? Await returns to work stations to get feedback to decide and powwow with TTI. Beside Ricochet Rabbiting gotta learn Bunnie Hops too.
 
Likely better beings to query . Cardboard template with cutout to suit trans , then lay over cradle - to optimise fit .
 
Hm, Matt, not a bad idea to me, as good number of extra things on Peel started out made of cardboard. I don't think I could template accurate enough here so working up nerve for steady hand to remove=relieve anterior hole rim ~1/8" and not go too far outside the numbered paint line. The cut out is mostly hidden with the primary on but I have no doubts where ever Peel slows down men will be looking close up her skirt, so I'll have to leave some fur to conceal any warts...

ugh, just stolen online photo, TTI is still a black box to me and ain't got my mind settled enough to analyze the photos posted already. Still ain't found a plug for the acorn one as set screw plug I've tried ain't same threads. But its my level of mahcinist, hand drill bench grinder and hack saws files and sand paper hammer and chisel.
 
Well turns out good ole trial w/o error [this time] only required beveling the inner edge of the forward lower cradle hole and TTI slipped in easy with almost interference fit tight squareness sweetness that we expect when paying for the best there is. One feature I will be savoring on Peel is how nice and pleasant everything is to access, remove and reinstall.
Next pleasant tediium is creating and oneinarow shifter and changine out rigger brearing to straddle the larger main shaft. Thanks for the mental hand holding worked a treat again.

Some UJMc dirt bike in a bone yard in the 250 two smoke range, so more tiddy-simple w/o remote reservoir. Will spray it golden. When Z plate removed the peg/lever/m-c comes off as a unit. Swing arm back up swash plates and rear loop struts afix on far end of Z plate. Half inch peg mount bolt goes thru a tab welded on frame just behind so very robust fixture now. This am put on seat and tank and sat on it checking the foot controls but resisted mimiking the whine of blower roaring out the megaphone snicking up to keep the front floating level. Grinning that other things can start moving faster now. 2015 will be a decade since I last rode Ms Peel.
 
Hope you have it ready for when the Norton Rally comes back East. Tail of the Dragon I think?
 
Hm I sure hope Peel is ready by then but I might not be to whip the Dragon but would love to experience it and see if Peels got the stuff to tackle it like I keep bragging on. If I can get hang of parking lot stunts down then maybe can scrap a bit and not go down. The toe grip stirup shifter I'll be making is for the too far over to get a toe under turns though.

If it were me, and if the cradle is steel, I would take it out of the cradle. Every time you hack and wack on the trans you are diminishing the value of the trans. Also, if you have not done so already, loosen up the engine through bolts on the back of the motor; it may ease up on the tightness a little bit.

Dances, the TTi box has a lot of metal in it which really is just for show.....this is seen well in the pictures brooking 850 posted....all of the area around the 'dummy' accomodation for the cam plate and the detent is excess metal and not needed for functionlity. The boxes weigh a lot more than the equivalent Quaife and this is part of the reason why. Nor can the metal I removed actually be seen when the box is between the engine plates. So I don't see it having the effect on the value that you do, but then again I want to use it not sell it. And mine already did a seasons racing in sidecar so has taken a hit on value anyway.

The reon I had to have a go at mine was because the 'detent' nut and the boss it is fitted to hit a cross mounting lug. I could not tip the box forward to get the shaft centres closer together. I releived it enough to get a belt fitted. we wil see how it all stacks up when I get the belt drive made and the fix the box rather than have adjusters.

I do see that Hobot's clearance issue was far different from mine. Rickman engine plates are more like featherbed ones. I didn't see that until the last few pictures, his problem related to getting the box in through the plates, not so much the amount of clearance when the box is actually in place. I am able to place both plates on the box, locate box and plates oin the frame and then bolt up to the frame and slide the crankcases (or complete motor) in afterwards, I don't have to feed from the side into plates that are fixed to the swinging arm.
 
Boy I have I lucked TF our to be functional into digital age to tap into the scope of intense competitive extremists trying to get ahead. So hope I ain't rubbed Mike or Steve too rough to steer me wrong. Standard AMC box reported as 18.8 lb and Peel's TTI 23.2 lb for about 5 lb difference [4.6]. My Quafe shell fit in TS cradle ok but needed ~1/4" removed from both the shell and the DS hole, ~1/2" fouling, mostly the back/lower rim of hole, so lucked out only some nibbles to fit TTI. Peel is a shape shifter alien meant for daily use and off road more than tract events, so can only make use-advantage of the weird WIDE spread 4 ratios if the Drouin works out - for more torque per mass than anything but pure dragsters or GP bikes. If Drouin don't work out then I'll revert to a big pumper carb and build up the Quafe with normal ratio's and learn to live with mere ordinary power band/wt performance and still spank sports bikes in turns but get passed on long straights - unless I cheat and short cut across the infield. I do not yet know if Peel's TTI can have other ratio's installed or configured to 5 spd.

Exce$$ over factory masses =
Maney engine block ~12 lb + TTI ~5 lb + Drouin ~15 lb + anti-detonation fluid system/air station ~ 15 lb - for ~47 lb of power adder/power handler for 6-7 hp extra inertia for tire grip to over come. Mostly lower/centralized mass though so hope the over 100 lbft and rather over 100 rwhp will make it worth it. If Peel configured similar to race rule cycles should come in about 300# in road legal tagged state. What concerns me most though is the spin moment of inertia pivoting on vertical CoG on both tires on and off road.
 
TTI don't fit cradle - whot do ya do?
A later update to this thread for those fitting TTi boxes...
I have a Mk2A 850 fitted with a Mk3 850 engine cradle and swing arm. The TTi box "almost" fits straight out of the crate, with only minor modification needed to the cradle on the drive side - approx 6mm/ 0.25" of material needs to be removed on the drive side plate in an arc from the 9 o'clock to the 10 o'clock position, as viewed from the drive side.
I'll post some pics shortly.
If TTi made one more simple cut to the gearbox housing on the same plane as the drive side mounting surface, the TTi box would fit the Mk3 850 cradle with no modifications required. I'll send a video I made of the area needing attention to Bruce Verdon, the owner of TT Industries. They're less than 5 mins from my home. Bruce told me when I met up with a few weeks ago that he's been (pleasantly ) surprised by how many road bike orders he's getting for his Norton box these days. Until recently, most of the orders were for race bike use. With a few minor cuts to the housing in the manufacturing phase, they'd be a much simpler fit for road bike use.

I’ll be fitting one of these soon, so any more specific details you can post would be appreciated.
 
Considering the amount of metal Bruce uses in the castings, intelligent use of a dremel to take some excess from it to ease installation is no big deal.

johnfitzw,
What final sprocket are you using? Store bought or custom?
I like it.
Cheers,
Thomas
 
Somewhat puzzled why you are using the Maney outrigger. Im sure the TTI box can handle the load of the clutch without it.
Especially if you go with a BNR belt set up.
Perhaps just a belt and braces view of things.
 
I run a TTI 5 speed in my race bike, there was a couple of tight spots on fit up in my steel standard Commando cradle, a flapper disc on a portable grinder on the gearbox case sorted them out, as pointed out, there is plenty of thickness in the cases to not have to modify the cradle.
I race with a lot of guys with quite powerful bikes that run the TTI boxes, none of them run outriggers, just another bit of kit that adds weight and not needed with these gearboxes.
IMHO
Regards Mike
