I just finished a restore of my '83 CV80. It's now international Harvester red and metallic grey. Looks sharp!

I have a new, better option for a drive belt than the industrial belt we have all come to know and love. A Gates PL30360 Drive Belt from a 02-05 Arctic Cat 90cc ATV is identical in measurements to our Yamaha belt, and is angled specifically for CVT drives. I installed mine and it grips right away without any noise or otherwise. Acceleration is improved. Top speed did not change.

I also ordered a 6 volt 1154 LED taillight bulb from superbrightleds.com. It's a plug and play replacement for our tail lights with very little amp draw.

I also ordered LED festoon bulbs and mounts for the turn signals in 6 volt. I installed them, then wired in a Chrysler dual ballast resistor (one side for each direction signal) to keep the thermal flasher happy. With the resistor, there's not much savings on amp draw, but the lights flash much brighter and there's no filament to burn out.

My headlight still works so I haven't tackled that yet, but when it burns out I'll convert it to LED as well. I'm also exploring an LED replacement for the instrument lights. Stay tuned.

My starter relay was bad, so I replaced it with a Bosch 6 volt relay available from Newark Element 14 for about 6 bucks. Works great.

I'm burning Klotz Techniplate 2 stroke injection oil and it smells like French fries.

We're taking it on vacation and putting a couple hundred miles on it Memorial Day weekend so I'll let you know how it all worked.

So I decoked my exhaust with a heat gun. It smoked for over an hour! After reinstalling the exhaust I took a ride downtown. 40 mph on flat ground. This was with 6 gram weights in the variator and acceleration was awesome. Belt works very well.

OU812,

I'm having issues with my lights, namely that my tail light and flashers are always dim and do not flash, even when I'm up to speed. I know it is probably related to my relay or grounds, but I saw your post and I've been thinking about converting to LED as I fix the other electrical problems. A few questions:

Which tail light did you order from superbrightleds? I'm not finding the 1154 under 6V, only the 1156 and 1157. I assume I'd want the 1157 for the variable brightness.

Which festoon did you use? The single or quad LED? http://www.superbrightleds.com/moreinfo/festoon-series-bulbs/de3175-led-bulb-4-smd-led-festoon/238/

I'd be curious to see how you wired these festoons in. Did you use the stock flasher housing? Can you take pics or show me what you did?

I've been looking at the 6V LED flasher on http://www.6vrelay.com/index.htm
I assume I wouldn't need to install resistors if I was using one of these?

My electric starter has also been going bad, it used to work fine and recently it just making a whirring sound when I press it as opposed to the "chug" it used to have when starting, so I've been kick starting. Is the fix to just get a relay or am I looking at something more involved?

Thanks for the help, I'm learning as I go and it's been fun. I put new rollers and a new belt in recently by following the FAQs, and then moved from Montana where we have 6 months of winter to Los Angeles where it's sunny and rarely rains, so I'm back to getting the Riva fixed up. Having a tail light and signals will certainly make it a lot safer to ride!

I'm still interested in what you did to convert to LED, but I fixed a few of my problems, just figured I'd report.

1.) My starter problem was a battery that had gone bad. Replaced the battery and it's fine now.

2.) Brake light: looking at the 6V LEDs on superbrightleds and your comment on 1154 vs the 1157 that I found listed got me thinking. I looked in my tail light and found the previous owner had installed a 12V 1157 bulb. Picked up a 6V 1154 and my tail light is bright. I can actually be seen at night now!

3.) Turn Signals: The 12V brake light got me thinking and led me to http://www.jacksscootershop.com/maintenance_tuneup_how_to.html which listed our 6V system requiring an 1129 bulb. Sure enough, someone had put 12V 1141 bulbs in the signals. I'm guessing when the previous owner went to the auto parts store for a replacement, the salesperson just searched for something with a similar base rather than taking the 12V vs 6V into consideration.
I had a bit of a hard time finding 1129 bulbs and almost every parts store I called in LA was either unhelpful, unfriendly, or didn't have them, but a nice woman at O'Reilly found some of these in stock: http://www.oreillyauto.com/site/c/detail/SYL0/1129.oap?ck=Search_1129_-1_3204&keyword=1129

You can easily order 10 of them here for about the same price I paid for four: http://www.oreillyauto.com/site/c/detail/EIK0/1129.oap?ck=Search_1129_-1_3204&keyword=1129

I didn't find 1154 and 1129 listed here on this site, in the manual, or in the CV80 tech specs. Someone will probably prove me wrong, but I wished it had been easier to find this information.

4.) Flasher Relay: I ordered a new relay from 6Vrelay.com before I discovered the bulb problem and my new relay hasn't arrived yet, so I decided to take my old relay apart to see how it works and check for internal damage. First off, I have the plastic square-housed relay. The housing easily came off by gently prying the plastic tabs on the sides. I didn't notice any damage or corrosion, but I could see the strip of metal that heats up and operates the flasher, so I actuated it manually a few times and then rehoused the relay. I'm not sure what worked, fiddling with the mechanism or the new battery, but my signals are now flashing at idle and they haven't done that since I've owned the bike, so I'm pretty happy!

It's looking like the 85-87 belt (32N-17641-00) is the same width (17mm or 21/32") and around 35 7/8" long according to my cheap tailors measuring tape. I'd guess it's closer to the first belt below......

With this in mind, the Gates PL30360 is 11/16" x 35 1/4" according to rockauto.com. : http://www.rockauto.com/catalog/moreinfo.php?pk=1146310&jnid=2&jpid=0

The BX33 is the same width but 36". Gates has a version as well:

I'm thinking the part number changed for few reasons, and probably just for $$ sake....
