I see no problem trimming the fins on the Webco cover to fit the pipes. Won't take much.

I could actually cut down the bolts that hold the ignition plate - that would bring the cover closer to the case, but I have other fish to fry on this project. Punt.

Wiring! Actually it is going better than it looks. You guys just use black wire, right?

So, what I like to do is wire it up on the bike and then use split wire wrap (the knit type, not the plastic kind at Autozone). Trying to retain the stock lighting switch position. However, I am using a later ignition switch position (i.e. 68) cause I don't want the key below my nuts. I'll keep you posted on progress. Here are the new coil brackets I made and a shot of the mess.

It's all in the timing, eh? Here are some shots using a timing disk off the cam to get the static timing set on my sled. Since this is an early unit bike, there is no window in the primary and no mark to use on the rotor. I made a pointer off the shifter using lead solder I have around the shop. Here are some photos of the process:



Pointer and timing disk.


The magic number 38 BTDC.


The Wassell unit I installed.

38o BTDC on the cam is the same as 38o BTDC on the crank?

This particular tool is designed to thread into the cam. If you look in the workshop manual you will see this set up as well. That being said, I guess the timing gears are either 1:1 or the grades on the tool are adjusted for the difference between the crank gear and the cam gear.

Short answer - this works.

Yes, but there is no mark on the rotor, no window on the primary and no pointer to time it to. That's why I used the static timing approach here. After I start the bike I will fine tune it by ear. I may strobe off the ignition unit, but I thinking lining up the two points (the lines in the image) should be the same thing as setting the static timing so it should not make a difference.

Still have to get the gas tank back or borrow a gas IV set up to get things sorted.

using the Pazon and Boyer set ups, once on the money I just tweak the static plate around as you suggest then back off when motor starts to pink.

Yes - the static timing on the electronic ignitions is usually right on the money. Even if you strobe the bike off the rotor it can be more difficult to do than using your ear because the mark often dances around like crazy! It's an imperfect system for sure, but you set it an forget it in most cases.

Still something missing. Can't quite put my finger on it. The bike is wired, timing set, side cover and oil tank painted - need to put fluids in it. Oh, yeah - NEED MY TANK BACK FROM PAINT!!!

I like this but to actually go desert sledding with it you would need high pipes and a big bash plate under the motor and frame.
It is a very harsh environment for low pipes

Still not done, VonWegener. That low pipe is on there only so I can set the timing with a strobe. I have high pipes. The bash plate is going to have to wait until the bikes runs, but I have a plan. Thanks for looking!

just a note for points type ignition, ibought a 750 that wouldn't rev over 3,000 - I got a triumph friend to have a look the points for me ,the points
cam bolts to the end of the camshaft on a taper, the cam rotated in a wobble- it had been put on at angle to taper, he removed it and refitted straight and fixed the problem. side note- I had ported the head on that bike and it would lift the front wheel slightly when it hit 3,000 in second

one other note , i too have no timing lock hole in my cases, so i replaced the alt and stator with later ones that have the timing mark, yes it is a bit of a pain setting without the primary cover on... but very accurate! and allows me to adjust the pressure plate that final little bit for pressure and wobble elimination. had to make a pointer and hang on stator bolts. as for the 389-689. they are just freaking cool! i wa going to ask if you were going dual or single carb but i just dont get on here often dang it! the webco points covers seem to have been made like the factory ones , ie deep or shallow. me im umm impetuious so i cut the pillar bolts , then tried the other i had and found the depth difference out. but my pillar bolts were in need of a trim .... nice very nice build.

Brent - thanks for noticing! Yes, the fenders are still available and the huge chain guard. I really don't need any more parts for this build - at least none that I don't have to make. I'm going to put a large bash plate on it - home made copy of the ones I've seen in the Webco catalog. Also, I'm building a proper desert front fender - flat. Soon as I get the tank back I am ready to fire it up. Found the last wiring Gremlin last night - was blowing the lighting circuit fuse when I put on the high beam. It turned out to be the housing for the reproduction switch, so I used the original housing. Solved.

I will trade for Ducati 250cc parts if you have any. That is my next build project once this bike is done. Let me know what else you have though - I'm always interested in trades - or cash.
