Re: Tank Goop!

Yep, you're going to need to start with all new fuel lines, because your bike pre-dates E10. You can use the common, black, J30 automotive fuel line from the LAPS for the external lines, but if you have fuel lines internal to the tank those are made with even more specialized hose rated for ethanol ...

Re: Horn no honky

One thing to remember, the horns pull a lot of current in order to operate, a meter does not. So you could have voltage indicated by a meter and still not have a good enough connection to supply all the required current. The way to get around this is to unplug the GREEN wire from the horn. To that s...

Re: K75 new but used

This is what I was telling you !! It's not going to run well until you get it out on the highway and run it 15-25 miles. You'll want to run a name-brand, high test , Top Tier fuel with built-in cleaners which you purchase the day of the ride. Fuels like Chevron and Shell have all that built in and ...

Re: 1975 R90/6 front brake switch replacement

My question is: How do I remove the old switch. The old one seems to be pretty tight and I am trying to avoid having to remove the whole master cylinder/reservoir assembly. Loosen the m/c band clamp, slide the m/c slightly rearward, re-tighten the clamp. The switch is fitted with a tapered thread t...

Re: R90/6 with R100 Jugs and Pistons?

Has anybody ever ported heads on BMW's for better airflow? I'm just curious... because I learned to do it on a 2-stroke engine and wondering if it's a benefit to airhead heads as well. The risk: Porting a 4-stroke without a flow bench is too risky. You could end up possibly screwing up the heads. N...

Re: K75 new but used

The main issue: Is it going to turn over fast enough to start ? You may need to go visit one of your racing buddies and use his "rollers" to jump it off in high gear by powering the rear wheel.

Re: R90/6 with R100 Jugs and Pistons?

I agree with the above. We use modeling clay in our shop. Simply assemble it and allow the piston to pass TDC one time. Then dis-assemble and check the thickness.

The "squish band" is the 3/8" of the piston crown closest to the cylinder wall.
