Yamaha IT 250/465 H & J Model Side Covers & Rear Guard
« on: May 03, 2011, 07:22:03 PM »
Some of this is news, some isn't.......

I ride my 250J hard and intend the same for my 465 when complete.
Sidecovers are expensive and hard to get.
Mine are good and bad.
DC Plastics are cr_p.
I make fibreglass things.
I can make sidecovers.
They will break in a hard crash.
They will be very cheap to get.

Naturally, there is a proviso......

I need some kind and trustworthy member to lend me a suitable LEFT HAND SIDECOVER.
I will need it for two weeks.
Preferably an eastern Melbourne member, so I can pick up and return part.
Once I have molds made for the sidecovers, they will be available for members for cost of materials and postage. Say about 40 a side or 60 for both.....
They will be grey in colour until I can achieve an exact colour code to match.
I will be using my split right sidecover to mold from.

There are some points of note:
My right sidecover is okay to make a mold from even though it has a split. This split can be closed and the corresponding mark taken out of the mold prior to production.
My stickers must be REMOVED. They do not sit flat. They maybe damaged during molding process.




My alien face sidecover is obviously not good to replicate.....


Cracked edges or badly distorted cracks are not good.


Heat has distorted this plastic beyond practicable use, however, scratches are okay. These will result in a raised line in the mold that can be blocked down prior to production.


This a recent guard made to suit 1976-79, DT250 and DT400, (maybe others too) and is indicative of the end result. They weigh about the same as plastic but are NOT AS FLEXIBLE. Easy drilled, sands easy and will accept many paint types.


I will be making molds from my own front/rear guards and headlight over the winter months.

Cheers,
Chrisko.

Sounds good to me Chrisko but I can't help you. On my 250H I have a spacer welded to the bolt where the side cover attaches on the rear on the left hand side. I did this 30yrs ago couldn't remember why after having sold the bike and then buying it back after 19yrs. Now I know why. All the best in your venture. I had a good laugh when I saw the pictures of your motorcycles ie 465. Thats a positive attitude. KP ;D

Give this man a round of applause 8)

How are you going to get them Sky Blue ???

If you have no luck, I have a left side cover coming over from the US that is in good shape, if you need it you can borrow it, but it may not be here for a few weeks.

Chrisko, what will you do about the section of the sidecover that pushes over the rubber grommet?  KP

Goody, questions..... :)

Sky Blue, Duck egg blue, IT blue in the face...um - short answer, dunno! If I can get a decent representative colour part, I can match it 95% true. If I had the actual PMS percentages I can replicate 100% true. Initially, I will leave it up to the individual to source some paint/decals, as these are intended to be used as a cheap replacement cover for your schmicko nice NOS ones. If I can get the colour right, I guess they will look good inna photo, but are essentially for getting dirty......

I've thort about them bl__dy DC things but all and sundry say they don't fit the lugs centrally.
Hence the need to use stock items that actually fit.
I intend to indvidually place the grommet key during production. They will be made up as a solid billet of glassfibre and placed appropriately. I make automotive splitters and spoilers, all with snap on or turnkey fasteners...no zip ties required!!!
The placement of some heat block pads will be the same process, if I can work out the best material...
Finances won't allow me to add heat reflecting insulation unfortunately.... :-[

I removed the stickers from my r.h. sidecover and discovered some extra work for myself. This negates the need to borrow a lefty. I have a rough lefty one coming. I got it with a whole bunch of stuff for my IT465 project from Leslie  ;D
I will do the repairs and cleanup on them together, this will save doubling up some processes.

I have a question or three however ???

I have not seen a good-decent-new sidecover for myself. Only photos.......

Is there a fine line inscribed for where the yellow/black number patch goes?


Is this mark or "print-through" line from the flange on the rear, evident on new covers?


Is there a dip, or shallow recess anything like what is evident in the following 2 pics?



Hoping somebody with a brand new one could pop out the shed and take a look, there is plenty of grouse shiney bikes out there everywhere....I know, I like looking at the pretty pictures.  ;D ;D

Cheers,
Chrisko.

Chris,
On NOS ones the yellow is actually paint. The only depression is where the 250/465 decal sits.
Any marks or lines on your's is most likely from a knife when cutting a vinyl replacement decal for the yellow. It is flat from new.
I'm sure the NOS-hogs will be along shortly to show off their prizes from dangerous and expensive EBay battles  ;D ;D ;D ;D.

Got your PM too ;)

Adam is correct, and unfortunately I have not been able to get my snout in the trough to get any NOS ones. KP  ;D ;D ;D ;D ;D ;D ;D

Thanks fellas, I think that decal line on mine is actaully a fine line of glue from the decal that was on there for a couple of decades. A brisk rub with my thumb made the line black and 10mm wide!! Those depressions from the mud shield affixed to the back can be erased on the mold, but if it is on there from new...I ain't changin' it. I know all the tanks have a seam line running down the side that is more or less pronounced on different bikes. Some look like a split and others with only a slightly shiner line.

I will have the chance of a colour match process too.

There is progress on this...

Cheers,
Chris.
