"t-handle" idle air screw

[Durvy825@aol.com]

Hey guys, I found this thread from several years ago on another group. Ever since they stop selling leaded fuel, I have often wondered about using a lubricant in the gas such as 2 stroke oil or marvel mystery oil (love that name, reminds me of snake oil). The bikes were FZR 1000 and ZX11. What do you think? If you have owned any one of the bikes/models listed above; :>I have the following questions: :> 1) How many miles did you put on the bike? 36,000. There will be more once I complete the transmission repair. :> 2) If you've adjusted the valves: :> a. how fast are they wearing out? They wear quite fast on the exhaust side, unfortunately (about 0.05mm to 0.1mm per adjustment). Using a gasoline additive such as Duralt or CD-2 (for carbureted engines -- amber color) puts a halt to this. I did my own little experiment: 6,000 miles, religious use of Duralt -- no adjustment, only some clearances changed by tiny amounts. 6,000 miles, no additive -- five shims needed adjustment--quite a few clearances changed dramatically. 6,000 miles, CD-2 -- no adjustment. I got the bike with 9787 miles on it in 1993, and I haven't had to change a shim in the last 12,000 miles since using CD-2 (I use 1/4 oz. of CD-2 per 4 gallon fillup).

It probably IS snake oil, but when I had my GoldWing the people over on the GWRRA message board were pretty big on using Marvel Mystery Oil in the gas AND in the oil. I use Spectro synthetic oil, so don't *think* I would gain anything by the oil treatment, but I do put it in the gas every other full tank. I don't see that the bike runs any better, OR any differently, so at the very least it isn't screwing things up...

I may try to use it in the gas, problem is, I won't have it when i'm traveling at extended high RPMs when I need it most. Unless I pack some in a little bottle. What do you think, 1 ounce to a tank full?

Besides making your oil minty-fresh, Marvel seems to do a decent job as a detergent in the oil, and it may give a little bit of residual protection if you run your engine low on oil. I used the stuff religiously on my '48 Willys jeep (first car), and on one occasion ran the motor very low on oil, without incident. Anyone familiar with the L-4 Willys "flathead" engine may not be impressed, since that was close to indestructible. But I only adjusted the valves once in the 10,000mi I had the jeep, which is good considering that it was definitely not equipped with the valve seats for unleaded fuel (used Marvel in the gas too). Valve seat cushioning on a modern engine would be less of a concern. Marvel will also thin motor oil a bit when cold, I add it to the crankcase in the winter instead of using thinner oil. Decent stuff I guess, a Mystery maybe, a miracle no. 2 stroke oil is not designed to cushion valve seats, it's designed to lubricate the cylinder wall. 2-stroke oil would foul the plug on a 4-stroke, I'd think. Not to mention be a smoky mess, all for the sake of you not having to do valve adjustments once a year. There are lead-replacement products out there that don't pollute, you could try one of those. Marvel seems harmless enough if used as recommended. Devon "Mark St.Hilaire, Sr" wrote:

The MMO bottle says 4oz to 10gal of gas, so I put in a hair or two over 2oz...

Or try running a tankfull of Trick, VP, or leaded Avgas every so often.....the lead WON"T foul your plug, and it smells like gas oughta. MMO does a good job on cables too.

Funny you mentioned this. I sometimes have used the CD-2 lead substitute and wondered if I was wasting money or actually doing something worse to my engines. I ran out a few months back and was debating if I should buy it again and was just about to post this question to the list! Anyone else use CD-2 with similar observations above? Mark B2 A2 A3

Well it's Monday morning and this was posted Friday. No one's said the obvious so I guess it's up to me. Never heard of CD-2 ( except when I listen to music ) so I don't know anything about it. I do know that in many instances shims need to be changed during the early life of the bike. After the valves seat it's common to go quite a ways - Conall went what ? 40k miles - without needing to change a shim. Bogdan

I used to have a DR350 and someone, either Thumper Racing or Baja Designs, used to sell a "T-handle" idle airscrew for that bike. It wasn't a tool but actually replaced the air screw itself. You just took out the original screw, put the spring on this 't-handle' screw, and put it back in. It allowed you to reach in there and turn the airscrew with your fingers instead of trying to get a short screwdriver or something up in there. For the KLR I just made an adjusting tool by cutting the tip off a small screwdriver and JB Welding it to a flat washer. It works ok but that exhaust pipe is real close! Do any of our vendors make something like this 't-handle' airscrew? If not, would they like to? (hint, hint) Don Sprinkle A12
