The IT465 and IT490 thread

[wfopete]

I'm a YZ kind of guy but at the ISDTRR in Tulsa acouple of weeks ago I spotted this number, so for your viewing pleasure:



This might come in handy:

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.

WOW HOO I finally got a Craigslist deal.
1981 IT465 $500 looks great, just needs a little tlc to get it back on the trails.
I do need one part I have not been able to find. A Gas Cap the # is NLA from Yamaha any ideas on where I can get one?

Try Speed and Sport. Google them.

Do you think I can get my IT465 plated for road use in California? It has never been in the system as it was just riden out on a ranch.

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.

As you can see from my above photos, my cases were totally wrecked due to a kicker problem. However, the kicker shaft that came out of the motor looks brand new. There is no indication of damage to the stopper tab at all.
I'd like to determine if perhaps the old shaft broke and caused all the damage and was then replaced, maybe with the improved part if I'm lucky. Or maybe my engine just had a different type of failure. I'm assuming that since I have the engine apart I should make sure that I have the improved kicker shaft to avoid any future problems. Any insight would be appreciated. I have big plans for this machine.

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.
