...maximum RPMs...POD Filters on the Carbs...not climbing all the way up the Clutch

I'm a chronic optimist, so I'm thinking you're gonna be WAY out in front on the trails, which will give you PLENTY of time to: "Put ya tow rope in the air!"..."And wave it like ya just don' care!"

With the final loading of the Trailer coming, I just wanted to give an update on some of the small updates for the RR:

-Bigger HeadLights

-Billet Bar Clamps

-Stainless Extended Brake Line.

-Taller Riser

-Extender for the Throttle Cable

-RAVE Popups to help Tune the RPM for opening.

-Aluminum to Re-Inforce the Chassis (It already had a slight wave forming)

-More to come

Ahhh.... I just have to ask. What's with the Smuckers? Are you snacking in the garage? My guess would be that you using it as a tool?  

From back on page 2:

"My nephew (Mini-GutZ) was told old people eat Marmalade so I he got me some....."

LOL

So it ended up in the background of the first few pics and I just carried it forward.

I do not like marmalade!

Update:

Well last year was disappointing, the sled would not rev (I believe it was the Voltage Regulator ), The NOS would pull hard to Mid-Range and done, a bit of Knock too.

It started  leaking oil out of the waterpump weep hole, I thought.

Spark Plug tore out of the head, needing a new head to be chambered, flattened and milled.

The engine cases\cylinders threads on several holes are starting to strip. (94 Mach 1 Motor, 25 years old +/-)

So... the VR was upgraded to a Mosfet design, I hope that will solve the Revs.

The leak turned out to be the seal for the cases, I think the NOS and Knock caused the lower case seal to blow out, also upgraded to better pistons and cleaned and re-tapped holes.

Once the engine was in the chassis and started it was pouring coolant out of a head bolt, it tore the threads and there was not enough depth to increase the threads. I was going to helicoil it, but instead went with using a 10mm bolt since it was the same bore as the heliCoil.

We are back in business!!

So far.....

Tidey up some electical stuff and maybe a little testing at the farm.

Untill the next "Earth Shattering Kaboom".....

*** Update ***

With the snow last week we were able to take it out and check the performance and see if we needed to tweak anything.

It ran great!! But we only had about a 1/4 mile of field to test it in and 1/2 of it was up hill. Need more room.

Smooth in the woods, vicious when you smack the throttle.

NOS seems to work too!! LongHair was upset there was no blue flame like in the movies.

This is my general feeling when we pull it out to give a ride:

Hang on for a full test in a few weeks.

BLAST FROM THE PAST!!!!!

Well, if no one noticed, this Winter Sucked.... We were able to ride with our good friends but not nearly as much we would have liked ( smiles per miles! ). So with no real damage or changes needed and an early start to the Off Season, I have some time extra time to bring this back from the dead!

After working on in the 670+ Engine I could not figure out why it would not REV past 6500 under load..... Engine was out then in, then out, checked case seal, etc.... ( Remember even with NOS it would not REV, and the NOS made it worse ).

So I pulled the y-pipe one more time, to look in the cylinders\Exhaust and see if any thing looked a-miss.... Nope....

Even flipping the shocks upside down made it no better. ( Dealership recommended it, they do it on all their New Sled Setups )

Then I disassemble the shielding on the Y-Pipe and found that there was a huge cross shaped crack right at the Y. Like any good idiot would do, I went and bought a welder, watched a YouTube or Two, then proceeded to burn a few holes in my riding lawnmower deck, in the end creating the worst weld seen by man. I did successfully weld the metal together and the lawnmower is ready for the grass... Coming off the high of melting metal together I grabbed the Y-Pipe and made the second worst weld know to man....http://quebecrider.com/forums/uploads/monthly_2024_03/rr-Pipe-3.thumb.JPG.c1c51954a6b9b0dc61bd0c5fb9e4862b.JPG

And burnt my thumb.... Pro Tip.... Glowing Metal is Hot, Be Careful....

Next up was a bit if grinding, sanding and prep.

I found a paint that was recommend as better than the Auto Parts Store Stuff and went to town.

Packaged it back up in the shields and reattached it to the engine. I feel it was disrupting the pipe harmonics so much  that it just would not pull the higher RPMs.... We will see!

Now while the chassis has been awaiting a revised motor we discovered that the Rear M-20\Air Ride suspension would not collapse completely, even with no Air in .... What??? This has never happened to me before... LOL.

Anyway after loosening and tightening the track more times than I care to count, I was able to determine that the larger 1.5 Lug and 8 inch rear wheel kit were bottoming out on the Top of the tunnel before allowing the suspension to completely compress. Odd since the custom tunnel has a kick up in the rear..... Soooooo... New Drop Brackets...

New Drop Bracket Fab.

I hoped the left and right bracket were identical, nope... I hoped the Air Ride mounts would still be mounted to the chassis, nope...

Used 1/8th inch aluminum sheet to make the two templates that could encompass the AirRide Mounts and levers.

10 test fittings later....

Gave it smoother\rounded shapes to reduce the chance of stress cracks, like why airplane windows have rounded corners.

Transferred the templates to thicker aluminum....

Pressed in some steel bushings to reinforce the wear points for the cross shaft

Now I wait for some barrel nuts, these will support the two sheets ( tunnel and bracket ) similar to a self piercing rivet and the bolt compresses the sheets together. With luck this will minimize movement and greatly increase shear strength and rigidity.
