Hey Big Andrew your bike looks really cool like that, I cut my windshield down but not that low maybe a inch taller, I can look over the top with ease, the reason for this mod. was because I had a really hard time seeing at night [glare], with the mod. I can see everything now over the top at night..
 
I got my new 25mm 1.5 pitch die today :grin: Works great and it's correct :grin: , I will soon post photo's Of how I make it..I did test one of the 24mm's with teflon tape on the threads and it didn't leak and you can see the marks with no problem.. My next trip to harbor freight I will buy myself a outside caliper, a tap and die set and I plan to make my own synchronizer for my carbs..Which will be in another post later.. :grin:

Sounds good beav.

Looking forward to seeing how this all works out.
Yes it's good, I put the oem site cap in the die and it turns nice in it..As you know the cap on the timing cover is the same size as the oil filler cap, 25mm so I tested my thread job on the new site cap in the oil filler hole and it turns nicely,someone may be better off buying a oem site cap instead of making their own, unless they have the tools in their shop already..Chances of having a 25mm die will be slite, it's not something you will find at any hardware store or auto parts store, gotta order it.. This is a really easy project if you have a little skill but not too much...The adapter is a whole 30 cents, o-ring 50 cents I think, I forgot, and the lexan is like 4 bucks or so . I used pvc glue to glue the lexan disk to the pipe.. If you will look at the photo of the three pieces the adapter has been cut at the nut, I cut that with a band saw, then I take it to the 1" belt sander and I take the threads down until the threads are almost gone but not quite, then to the table vise, I clamp it and put the die to it by hand turning it and reversing it until done, once threaded I test the threads on the bike oil filler hole.. then I cut the thread length down to 9/16" from the nut, that's the length of the threaded end..I sand some on the end and clean it up, done with that part....The Lexan is clamped down to the drill press on a piece of wood, this is a little tricky but not too bad, start drilling but don't get in a hurry because the lexan will melt, so what I do is stop drilling about half way thru and clean the holesaw[15/16"] then proceed on, then sand that little disk to fit tight in the pipe and sand the sides a tad, [patients] place the glue inside of the pipe and place the cleaned up disk on a clean flat hard surface and push the adapter down onto it flush, don't get glue on the glass part only the edges or sides if you do it will mar the lexan....I'll get into making the marks for the crosshairs later.. pretty easy..Again, you would probably be better off buying a new oem one from someone else if you don't have the tools..However the oem one has two glass lenses which makes things really a lot harder to see the marks but it can be done..The trick to seeing the marks is simple, even with a full engine of oil you can see the marks way way better at night..The daylight makes it harder to see but not impossible, at night you shouldn't have any problem at all seeing your marks.. :grin: More on this later with photo's
 
Here are some of the photo's I said I'd post, all of this is pretty much self explanitory but the photo's are still neat to look at.. And explaning as I go make things simple..[already simple] :smilie_happy: ...View attachment 5View attachment 4View attachment 3View attachment 2View attachment 1 Now put all together make sure it doesn't leak by putting some water into the cavity and place the cap on a paper towel if it gets wet you have a leak, oh and that glue holds like a son of a gun, that pvc glue really grips it if you want get a tiny drill bit and drill in a hole thru the sides into the lexan and put a couple of tiny screws in and cut the head off flush... And that's that :grin: Works just like the other..If I'm looking at the timing using the cap I'm doing it at night.. :grin: oh yeh, I'm using a really cheap timing light from HF and I can see the marks fine..You should see them much better with a better light..And when I screwed up with the first 24mm die, I also bought 24mm o-rings now I'm glad I did because the 25mm make them fit nice and tight so they won't fall off..Good luck.. :Egyptian:

Relax. If he shared it on the internet he probably intended for you to use the idea. :laptop: And if there is no patent, then who cares? :good:
Yes sir, that's the idea, not to take away from anyone or anything like that, but there are guy's that have helped me in many ways so I thought I could share my findings, it is most important to make positive that the lexan is glued in good and no possible way it can fall into the engine while running :shock: ... that's why the screw in the side is a good idea..I bet a guy could just sand it smooth to fit the hole and then just push it in, but that's mickey mouse so I'd thread it..After gluing it into place I tried pushing the lexan out using my finger and I can push it out, it's in there tight and glue.. Good..I was thinking of just drilling a hole thru the side into the lexan and then filling the hole with JB weld, once it dries it would be like a pin..I gotta get a small drill bit, tiny..
 
You guy's are gonna think I'm a nut, I took off the o-ring which puts the end of the site cap threads right down to the crank and I kissed it then turned it back a 1/4 turn and fired the bike up, guess what, no oil leak without the o-ring, then while it was running I turned it down a hair just to watch it [Crazy]....I gotta tell you, that I have enjoyed messing with this, you really don't even need to cut the length off the adapter at all, the length of it is fine if you just make sure you have a flashlight and watch it closely when you whind it down, it would be a hair longer with the o-ring on it, you can make it long if you removed it, shouldn't need to remove it though.. seeing the marks is no long an issue for me, as long as it's done in the dark..I'm considering selling a kit for cheap or maybe not..Still unsure..
 
okay beav so what your saying is you can crank this down to where it sheilds off the oil slashing to the point you can see it even at higher rpm ...seems like the inside could be marked making the marks almost together down in the sleeve .... teflon tape would be better than o ring to begine with i think ....you have to make me one one too while your all set up ...i would like it as the cap that never has to come off .....history proves that i cant remember to put it back on before all the oil gose everywhere :smilie_happy: :rant: :doh: :hihihi: :mrgreen:

So the plastic must take care of sealing it's own.
That good, one less part to get lost!

I really anxious to see how this works.
Sir it's on it's way with another little surprise for you, I got my sticker today and patch thank you, I also just posted this on my other favorite site I like both you guy's equally..

No joe, that mark at the higher rpm is still hard to see because the oil bubble up, even at night with the one lense oem one it's near impossible to see the higher rpm mark, but you can sure see the F1 and F2 marks fine,,however that being said I checked it with full oil, so who knows what you will see with lower oil..Joe with the oring off and not cutting any length off the adapter at all you can kiss the cranks ha ha..man if you want to scrape it I bet you can..I wish I could wrap the adapter with like some leather or some material to stop the oil splash totally..keep in mind I have a cheap timing light .. Hey maybe if I resessed the lense then turn it down until it touches the crank while it's running, wow is that crazy Joe or what, I'm going try it, the marks on the crank are resessed lower but that sucker better spin perfectly.. :grin: Joe maybe if I sand down the side real thin then try it with a resessed lense, oh I would not use one of mine for any perminant use, it's not designed for that, I'd stick with the oem one it's a better cap..The cam pully method is still easier to check your timing in my opinion.. :grin:
 
beav sent me a OEM timing cap and the "Timing Site Glass Cap or mirror thingyamajiggywatchyamacallit....." he made.

I had a chance to try them both out today and compare.

I did a video comparison of both but it's hard to get in there and the video camera drops frames, here's part of that video:

If you watch closely you'll see the F and 1

(Maybe someone knows how to get a vid that won't drop frames)


Sure wish I could get a good video, even the marks I put on the cam pulley the camera drops frames, it doesn't like the flashes I guess.

His cap seems to work a bit better than the OEM.
It threads down deeper and blocks more oil.
I could see the marks with both caps but after filling in the "F" scribe in the crank with white out the mark really showed up good with beav's timing window.

I guess the acidic oil that I've been putting off changing dissolved the white out so paint would be better here.

Beav's timing window is definitely worth the $10 he's asking.
It works better than the OEM which is what, $40 some dollars?

Thanks beav for sending them to me, nice work!

No... I won't be selling them... but if you want to make them you know how to, the main thing is they don't leak oil ....cheer's :Egyptian:
 
It's not always about money, I just wanted to see if I could do it... :music: so it worked cool... it works better at night...

Are frames being dropped in your camera or in post editing software? What are you useing for a camera? If it's a pocket digital camera set to "video mode" saved to an SD card, I wouldn't expect it to process as fast as your timing light can blink. Maybe try a camcorder that uses tape. Preferrably one that will allow you to adjust shutter speed manually.
If the frames are dropping out in the post editing software, it could be any of a hundred reasons, but I would make sure the frame rate in the camera matches the frame rate being rendered in the software.
