    Looking for color matched it 490 handguards, ones that wrap all the way around with aluminum bar in them. Can they still be bought, I checked maier plastics site and nothing it blue, not sure who else would have that blue. I guess if I can't find the right blue I can settle for white or black.

    The chances are very slim you could get a plate for it. We are in Kalifornia.

    What are my options for better lights?

    I would like to go to 12 volt if possible. Can I get my lighting coil rewound to do this or is there a 12 volt lighting coil that I can install?

    With the advent off Cree and LED technology lighting is no longer an issue. Check out Baja Designs, Cyclops or google it and only your pocket book will slow you down. Might even just run 'em off a separate battery and forget the lighting coil thingy.

    It's not the shaft that fails.It is the spring.The outer sidecase wears out and the gear is allowed to move too far on the shaft which shears the spring where it goes into the shaft.the sheared piece typically gets lodged between case and shaft pushing the back out of the case.I was able to bring mine back to spec with a shim against the worn out side case and a brass bushing inserted from the inside into the center case after some machining and tig welding. I had access to that stuff so it was the cheaper way for me to go.If you don't fix it right you will keep on breaking kickstarter return springs.Knowing the proper starting technique will save a lot of wear and tear on this area and you.I got where I always had the bike running in 3 kicks or less.

    Best forum around! I'm looking to do a front disc brake conversion on my IT. Its not that IT don't like or think the drum brake isn't good enough, but I'm having a problem when I lose braking due to prolonged heat from hare scrambles and hare n hounds. Any suggestions? Thanks

    Did you install new brake shoes? I just checked my brake cable on my YZ465, and it has been sticking. I'm replacing shoes and the brake cable. I ordered a Motorcross style of shoes from EBC , # 508G. They are grooved to displace water, mud and maybe displace heat better. I guess I'll find out. :evil

    You'll have to keep me posted on how the EBCs work out. You could be right about the grooves displacing the heat as well as water, mud and whatever else could plague braking systems. I'm not a big fan of changing away from OEM equipment, other than pipe, silencer and routine replacement parts, so I would definitely like to keep the front drum. Please keep us all up to date!

    Yessirree, 1981 H models were all white.

    I owned a 1981 IT-175H, and it was good.
    I felt the 1982 IT-175J I owned after that was even better with more power everywhere (especially the low-end) and better suspension and ergonomics.
    I wish I owned one, today, actually.

    I also had a 1982 IT-465J that was quite fun to ride due to it's very strong torque and general easy-going nature to it due to it's easy-to-use power characteristics.
    It even started easily.

    I also had a 1983 IT-250K that basically felt like a YZ with a bigger fuel tank and lights and blue plastic.
    It was pretty fast.
    Not a torque monster (although there was enough down low), but good mid range and top end.

    I have recently been thinking that Yamaha's excellent photography in their advertisments must be responsible for my bike lust in those days.

    The colors especially were very vivid

    Even with all of the technical improvements over the years, new ads don't have the same pop as those shots from the 80's

    Hey guys,, I've got some questions and concerns on DC plastics. I reading that they don't come pre-drilled, but to be honest that's am easy job and the least of my concerns. I'm also seeing pics of the ITs and the edgings don't look like the fits and finish (edgings, cuts and fender molds in general) are poor at best. I also noticed the left side panel, over the silencer, is probably the worst mold I've ever seen. Is this all of the DC IT490's or just a very unfortunate few? I have all OEM Yamaha plastics now, but don't particularly want to ruin them at the prices they run. Thanks for your input in advance.

    All blue in Aus from memory. I've never seen a white one but love it from the above pics. White seems to suit a lot of bikes.

    I reckon the headlight in those pics is different (smaller) to what we had here as well but stand to be corrected.

    White (in the USA) lasted for just the 1981 model year.
    In 1982, it was back to blue.

    From pics and brochures I've seen from other countries, the USA lighting was smaller since it was off-road equipment.
    Other countries got bigger headlamps because they were either street-legal straight off the showroom floor, or easily made so.
