IT400E
« on: November 25, 2014, 06:01:53 PM »
The Yz125h resto has been bumped back for this It400.  It's been sitting for a while, however most parts are there.  I have been well and truly bitten by the IT bug (obsession)-



Motors coming out this weekend and hope to have the frame blasted the following week.


cheers Tony

The rebuild begins.
Check the ring gap. Keep in mind this old girl ran.



Its on its 2nd oversize, so its out to .75-1 o/s. My plan is to run this 400 in the amtra/suzuki high country ride next year.
Things to do (heaps)-
1. Rebore, piston & rings
2. Gaskets
3. Repair exhaust
4. Paint frame, motor, swingarm..........
5. Relace rear wheel (broken spokes)
6. Headlight  - thanks Simon
7. IT400 forks and wheel (has RM? Forks)
8. Tyres (in stock)
9. Seat reupholstered
10. Swingarm and headstem bearings
11. Historic reg
and all the things I have forgotten.

cheers Tony

You find all sorts of dodgy surprises during resto's. Not the first bike I've had with the swingarm bushed-



All Balls make a kit for the IT400F : 28-1185. Has anyone use this kit on a 400D or E?

The pipe has seen better days-




However salvageable until I find something better

That's a nice pipe Evo, may have to put aside a few more pennies.

I found a few more challenges with the swingarm. Someone got excited with a welder-




Grind, drill and pin



Dodgy pillion pegs removed and frame cleaned up for painting



My piston is on its way from the US, probably the wrong time of year for shipping. Plenty to do whilst waiting.

Everyone have a great christmas.

I ground it back and all was good..... 8)

You defiantly have your work cut out on this bike. It will pay off in the end but it can be very frustrating in the mean time. I have never seen rings like that before. It almost looks like they filed the one side off before installing them. I hate cobble jobs and worse weld where it should not be. Keep at it and you will get it right. Great work so far.

Time to resurrect an old thread. With other bikes to ride some projects get relegated to the back of the shed.
Well it's time to get motivated again with a pre 80 class in the australian 3 day vinduro in May.
Motor is reassembled and ready to go back in the frame, however I have an issue with the forks. This bike has had its triples bored out to fit a RM 38mm front end (1980-81).
The bike must be period correct.
Does anyone in oz have a 36mm stock frontend or preferably a 38mm 77-79 YZ forks etc?

I have a set of '80 YZ465 forks/triples if that will work. I'm willing to ship but the cost may be prohibitive.

The IT175J and K yokes use the same casting as the early 36mm items. I expect Yamaha saw how much meat there was and thought 'we'll just hog them out to 38mm'!

I'd try and avoid any forks that are too long such as the IT250H/J as your bike will steer like a Harley!

I think Mark uses 38mm forks on one or more of his creations.

Cheers,

Dave.

Yes. On the IT175F I had been using YZ250D forks. But these are rare due to being in demand by VMX Pre-78. Best to avoid if you are not doing Pre-78.
I had some issues with them due to wear and so I got some YZ250F forks and used my good YZ250D tubes and fiddled a bit to get the travel about the same as the YZ250D forks.

For my 400E 'Hopetown Vinduro' bike I will be using YZ250F forks. I will push the tubes through the triple clamps as far as I can without limiting travel.
It will be a slow steering bike but I am ok with that as it will be setup for fast open events.

After many years the 400 is complete and made it to the Australian 3 day vintage enduro in V2 class (pre 80).

Passed scrutineering and sound check.
It required a working headlight, horn, tail and brakelight.

Alas, a fairy story was not to be.
I made the first loop in ample time and had a blast on the special test. Loop 2 was disastrous. I lost all gears after negotiating a steep clay hill decorated with a couple of other competitors.
After some fiddling I managed to engage 2nd and managed another 30km before the old girl gave up the ghost.
Full credit to the A3VE recovery team, they had me out in about 2 hours after I called and special thanks to the boys from Yarram club who helped push the bike out of the single track.







I had a blast and there's always next year.

Nice one Tony, might be a bit of a godsend being out. It is pissing down down here in Vic so can only assume it will be treacherous out there.

Maybe all Vic It riders can look into this event. ;D

Thanks Ty4 for the triples, no issues from the scrutineers with the 36mm forks. I was anxious about the noise test, however it passed.
........and Sluggish - the old girl was a great base to save.
Just a week before the race - damn, I need an air filter. I called a number of bike shops to no avail. So I emailed twin air in NSW. None in stock, however they could make the filters in 1-2 days. 2 days later I had 2 filters delivered - great customer service.
The 400 requires a new selector shaft and then will be back in action.

cheers Tony

I hope you will be running it at next years A3VE.
Phil Green did very well on his, taking 1st in class and 7th outright.
My plan is to build my 400E for next years event.
A 3 way contest between us on our 400s would be great!  :)

I'll definitely be back next year Mark and it would be a grin having the 400's dicing.
Phil flew past me on the special test, he had that bike singing.
Harko it would be great to see more IT members next year at this event. The tracks aren't that hard (a bit slippery) and there's always the noncompetitive rally.
