I hear what you're saying JOG and I've thought about that but his 87 is supposed to have the same jets as mine and he's getting 54.5.  I don't get it.

Anybody else here running a 86 - 88 completely stock?  What kind of mileage are you getting?

Well I'm usually in top gear by 45 mile per hour and I wouldn't consider that winding it out, would you?  Lower gears pretty much the same but I don't know the exact speeds.  As I said, the plug is black but it never fails to start and runs down the road just fine.

Ha! I think your dad was telling a little story there cause I haven't been able to find any hills down here yet.

I'll consider the smaller front wheel.

Well, from 93, when I bought it, till last fall I had only put about 2,000 miles on it but since I retired and moved down here I've put over 3,500 miles on it.  Haven't been riding quite as much lately since it's been over 100 almost every day and I just don't like riding around in a furnace.

The reason I ask is,, IF youre gonna go chasing Better MPG, youre gonna spend some $ & some time. Before I did a deal like that, Id have to decide if its gonna be worth it in the long run,, If you spend $100.00 & 20 hours of hair pullin & you get 10 MPG improvement, how many miles will you need to ride before youve saved enough gas to make it al worth it?
I figure I could change the plugs & wires & rotor & cap on my ol pikkup & get better MPG,, but its okay now,, not too bad, & Id have to run thousands of miles to recoup my investment in saved fuel, so, Im not messin with it now,,

rl153, if it were me I'd just bite the bullet and buy a new filter, then there's no question that it's good.

JOG,  not really chasing fuel mileage.  I could live with the 37 mpg and just go on but what bothers me is why is it running so rich to start with on a completly stock engine.  Running rich, at least that rich,  just isn't good for the engine.

Well, my belt is a tad too tight, but that's a personal problem

Oh, you mean on the bike.  I've checked it and it seems ok.  The bike rolls plenty free enough and actually the rear brake could stand adjusting up a little.

Check your tire pressure too.  Including with load.  Shouldn't have that much effect, but several little things could add up.

One thing,... that's a transient enrichment valve...  forcing it open is adding fuel...
...at least I think so...
