Airhead "Tips and Tricks"

[mikyheimann]

I put this kit on my bike - very good midrange - a big difference to the original 800cc.
works well with 800 heads and carbs, a little extra comp ratio more than the original 1000 pays dividends. I recomend.

Thank you, todah.

I have only spoken to one other and they swear by this as the mod that gave the most (not necessarily the best bang for the buck) performance and kept things reliable.

Thank you - next topic

If you have one of those emergency oil cooler bypass blocks, make sure it fits and works before you need it. Mine required about 15 minutes on a bench grinder to get it to fit my GS. I would have starved to death trying to file it with a Gerber tool.

I've always tried and achieve the "just a slight drag" effect from my feeler gauges when checking/adjusting my beemers' valves during services.

I was the right feel the first time, but over the last 46K miles I've apparently gotten looser and looser in terms of valve lash clearances.

For those of you who have done this service, you know how subjective and uncertain the achieving of the "just a slight drag" can be. Specially if you don't do this very often....like say every week or more.

The last one I did, caused issues, which led me to take my beemer to an indie mechanic who informed me I was setting the valve clearances way loose.

Perusing the web, I finally found a way to "quantify" and ensure the valve lash clearance is correct and "not too loose".

It's all in this blog posting: LINK

I adjusted my R80's valves, which I found too loose, this morning and can say with certainty now that the engine is quieter (less clattery) and she runs sweetly.

So don't go with the "loose valves are happy valves" mantra as I did, you can achieve quieter valves.

Note: there's still a very low ticking noise, but I have to really listen for it now with my helmet off, before I could hear it with the helmet on!

i do use the next up feeler gauge to see how it fits. Usually, though the next one up gives you just a slightly more draggy feel than the desired one, so I figure if I cant fit the 2nd one up, then its pretty good. A little loose is better than a little tight.
I use 6 and 8 intake/exhaust so my go/no go for the intake is the exhaust feeler.

Seems pretty clattery, nonetheless. I suck at valves, but they haven't blown up, yet, and the measurements dont migrate all that much on the new heads. The old heads at 90K would move a lot from when I set them to the next adjust.

any idea what car this is supposed to fit? i can't find anything from fram stateside with that number.

also, randyb mentioned a toyota truck filter that would work? any specifics there?

I have been using this for the last 15 yrs and many 1000's of mile's with no problem's what-so-ever. They cost a 1/4.

I can't remember where I saw that. I stole it from another site or thread. It's buried in the original post.

I know two old Moto Guzzi guys who section out the middle of truck filters. I may be that cheap.

You may not have these Ford model's in the U.S? Maybe a similar model?

Mmmm, it's not down loading the site so maybe Fram is not recognised in the U.S. The Ford model's are Fiesta injection and diesel. If you scroll to the number you'll see the car model.

Safe riding Karl.

thanks karl. looks like in the US that translates to the following:
a 1993 ford festiva/fiesta/aspire fits the bill.
the part on fram's US site is listed as part ca6867. i'll see if i can find one locally and report back.

You've got me interested now. Good luck and let us know how you get on.

I ahve no issues with my clearances. It's the rocker play that's driving me nuts. No matter how much I try to perfect the shimming, it gets noisy again after a few hundred miles.

I just try to use the best earplugs I can find

[bmwblake]

the cross reference didn't turn out to fit. i did find another option. i'll be working on it tonight and will post pics. i hope nobody ran out and picked up an incorrect filter.

Great thread as I just read the whole thing.

A co-worker just informed me today his wife's grandfather just died leaving a 75 90/6, 79 R100RT and 90 K100RT behind in the regions around Tulsa, OK.

He wants to sell the last two and get the 75 running but has zero bike or mechanical experience. This is where I come in.

I'll be baack/ [/arnoldvoice]

the pics aren't worth much and the camera's battery is dead. stp7755 is a pretty close fit, though it does require some trimming on the width. i found it for 9.99 at a local auto parts store. i'll give it a try for a while and see if the inside of the airbox stays clean. i'll post results.

This thread looks great from the perspective of someone looking at buying a mid-eighties airhead. Is there a way I can download and/or print out the entire thread without doing it one page at a time? Thanks. Charlie
