I have been able to find a CCI sticker locally. However, it looks diferent to the one I previously had. This one is 45mm long and 15mm high. The letters are black with a white outline.

Are there different types of stickers and do you know what the one for the 71 T500 should look like. Probably just being pedantic, but once it's clear-coated it's on there for good.

Thanks for any advice

its most defiantly an issue I have open filters on my GT500 runs much better but the boots kept splitting so I made a support piece of aluminum strip from the top of the frame were the old air box was, going down and under the carbs to give them some support :grin: Andy

No, that isn't it. That's for the charging coils on the GT500 with PEI ignition. Your bike doesn't have PEI, and your stator is different. And the manuals make no mention of resistance readings on the earlier bikes that had ignition points. But the readings you got are similar to those on two coils that I have.

Hook a voltmeter across your battery terminals and note the reading. Then rev the engine to 5k briefly with the headlamp on and note the reading. It should be at least one volt higher than before you started the engine, and not less than 14 volts. If not, and if you're sure the battery is good, I'd suggest testing the regulator and rectifier, even though you say they're okay.

I've already done that.every thing top to down is ok except the alternator.
now I'm starting to get a little pissed off now. so I think I'll just put every thing back together and sell as is,.
I haven't got time to fanny around with this old bike any more and I want to sell asap as theres no room in my garage.

So, went and picked up the parts yesterday.

For the princely sum of $120, I was able to get nearly new front rim/caliper/axle/speedo drive, nearly new rear wheel/brake/brake cable/lever, a nearly new headlamp/bucket, nearly new seat, chain guard, and a (free) spare seat to use while I have this other repadded.

Not a bad price, if you ask me!

Took me a three hour round trip to pick it up, but not bad, considering my car sips gas.

Am I correct in thinking that I can put a pair of right front fork legs on a 380 to make it a dual-disc set up? I know I'd need to change the MC, and a SV650 MC is a good match for it.

I don't think you can do it that way. It would be better to get a GT550 or 750 front end. The offset for mounting the calipers is not centered on the fork leg. You might make it work with spacers or some machine work.

I am not 100% certain here but I think the 380 fork legs are smaller than the 35mm legs on the 550 & 750. I'm thinking 33mm on the 380. That would mean an entire front end change to go to a dual disk setup.
You can't use 2 right legs as only one would be correctly machined for the caliper location. Not to mention the fender mounting holes are pointed out on one leg. :bwall:

How to tell if choke is on?

Post by Admin »

I'm still trying to work out the bugs on my 76 gt750. The left cylinder isn't firing unless I put my hand over the carb intake for a second, then it sputters and fires for a few seconds then nothing. I'm also not sure if the choke is on with the lever up or down? Thanks

choke is on when the lever is down. Off when up. I would suspect a clogged pilot circuit on the non firing cylinder. By placing you hand over the intake you are forcing the carb to draw in fuel. It gets enough to fire a few times, then runs out again indicating there is no pilot fuel for it to run on.

Might I suggest also considering a more modern caliper and master cylinder.

EX500 kawasaki is popular and the SV650 would also work with a small adapter plate.

I modern caliper will probably be better than 2 old ones and it would weigh less too.

Lane has EX calipers on Blueboy I believe.

choke off- up

Post by Admin »

I'll take them apart for the 3rd time. 1st time I got one of the diaphrams in crooked. 2nd time I failed to clean out the middle air jet properly. Thanks!

There is a tiny little passage in the bottom of the float bowls that routes fuel to the choke circuits. It happens to be the easiest thing in those carbs to clog, and the most difficult to get clean. I use a 9 gauge guitar string to start the process, then blow it out with canned carb cleaner, followed by 150 psi air.

Yes and you use that same string to go thru the centre of the idle jet, you need to be able to see daylight end to end, not just thru the holes in the side.

Mike - The '71 T500 definitely had a CCI decal. It was white, and the type font was an outline if I recall. The color of your tank will show through the center of the letterforms.
