The 350 is not a true full stator and looks similar to the setup on a Yamaha Blaster. It has a separate coil for lighting and charging. Neither one produces much power.

The charging coil is listed as providing 2.5 amps at 3,000 rpm (day) and 1.4 amps (night).

I think that the distinction between night and day specs is whether or not you are running the lights, but that doesn't make much sense to me since there is a separate coil for the lights.

The lighting coil specs are: 11 volts or more at 2,500 rpm.

If you multiply the 2.5 amps x a nominal 12 volts you get a small number of watts. Enough to run some LEDs, but sheesh, what a wimpy electrical system! How are we supposed to run the Baja 1000 like this?

Grrr so after installing the new kickstarter shaft on the 85 bw200 and putting the motor back together there is only 35psi compression. Squirting in a bit of oil into the cylinder bumped the compression to 50 psi.. I reused the stock piston and rings as they looked o.k. to my amateur eyes..

At this point I'm thinking of just parting the bike out which honestly I'd feel guilty about as the bike is just so darn cool.

Any chance it could be that the rings just need replaced?

Anytime the cylinder and piston are seperated you should replace the rings and hone the cylinder. A lot of people don't but in my experience it's a good precaution.

Sorry for the newb question but what is the typical cost of honing a cylinder?

Depends on weather or not you want to do it your self or have a shop do it. Honing is not a big job but requires a little time and a good variable speed drill. Or a actual honing machine, which is what most shops would use. Here in Canada we have a bargain man's store called Princess Auto and you can pick up a decent hone set for about 20$

Dang, the electrical system was an afterthought

As long as the plug fires

epix,
I found this great article on honing your cylinder. Worth the short read for the unknowing.

Thank you sir :) One of my riding buddies does some engine work on the side, so gonna have him take a looksie at the cylinder after I pull the motor out of the bike and go from there.

Your very welcome :-D

An extra set of eyes is always a good thing, especially experienced ones.

Good luck and I hope your bike sees more trails instead of being parted out
:-)

Here are my two little gems. A 1987 Honda Fat Cat, and a 1985 Honda 250R with Missile Kit. Very fun machines!

Wow ATCTIM...

I'm super jealous of the 250R Missile!!!!! When I was a late teen I owned an 84 ATC250R that was bored out 80 thou, with a 38mm Keihen carb and twist throttle, FMF gold series fatty pipe and power core 2 silencer. Its was a rocket to say the least. I always drooled and dreamt about doing a missile conversion but the kits arw very hard to find. Most come with the rest of the bike attached lol.

Great Bikes man.

Looks like the company is actually still in business that makes the Missile kits

atctim,

Are those Jason Hall triple clamps on the Missile?



This is my latest tool purchase. After three consecutive rides with three catastrophic tire failures, I needed something to help me break the bead on all the antique tires I've been using.

I have been using all of the redneck bead breaking techniques but when it came down to pulling the paddle tire off of the 10" aluminum rim, I didn't think that using a truck and a 2x6 was well advised.



The Beadbuster cost $100 (which nearly killed me) but it is made in the USA, so that softens the blow. On the stock 9" steel rim, it took several tries and the tool had to be moved around the rim to get the bead off.

On the 10" paddle tire, it popped the wheel off with two applications on one side and a single time on the other.

In other words: it works. Eventually, it will pay off.



And it is a significantly better option than the Sawzall, which has been my last resort for really intractable KT646s.

Regards,

Mr. BigWheel
