Looks like it is my labyrinth seal

why wouldnt it work? sure it would. isn't your charging system working? since you know automotive, its basically like a petronix ignition, but for bikes.

So, it ONLY replaces the points while retaining the charging coils?

I wasn't aware of that. Then that would fly for me.

I understand the value of being able to build a curve, but the stock ignition doesn't and I am happy with the level of performance the bike has with the Bassanis when it runs right. I can live with leaving those extra ponies on the table for the cost difference.

The cost per horsepower does come into the equation for me with systems like the Vape.

Thank you once again for the insight.

so the tytronic, dyna etc just replaces the points.  the cdi does both.  the hoi has a curve built in,the vape does not, you have to add a component for that. my 70 r5 has a vape cdi. it is otherwise dead bone stock down to the bore and it runs great, and im def not chasing hp. reliability was my goal.  0.02

[RDDave]

Well, if reliability is questionable with the Tytronic, then that WOULD be an issue.

But the Tytronic is available for a lot of different bikes and I don't read about any more failures than I do with some of the other conversions. If I am missing something, please let me know.

One more question please; I don't like the throttle cables that someone put on the bike and plan to replace them. I would appreciate recommendations on whose to get.

Thanks...............AGAIN!

i run 2 of the tytronics. one on the ls2, one on the 2nd t500. money isn't an issue/concern with parts for me, so, that should tell you they are worth it.  i currently run 5 vape cdis, an hpi, a dyna, and 2 tytronics. im all over the place. lol. just, simple.  zero reliability issues with any, and thats the primary reason i run them. some its performance, but honeslty, just on 2.


as far as cables, if they are stock reach out to economy cycle.

I take it the Tyronics can't cause the motor to run backwards like my old Dyna does? The damn thing has been sitting there idling, lets out a cough, and it's going backwards.

they do not. i suspect they figured out you need longer dwell, and that was the issue with using a 4 stroke dyna trigger  on an rd.

almost 20 years ago i guess, i modified an Allison ignition to use on an rd, single coil, ran into same issue and when i pie cut trigger wheel the issue went away. the tytronic & and nicks dyna, employ a similar system but use multiple trigger magnets in the rotor to get the dwell needed.  even the vape cdi, early mzb ones, didnt have a ramped trigger on a cdi and could start backwards. ask how i know...   

1st pic was the 1st attempt i did, from 2006.  the later ones were cut on a lathe and had a big pie cut. this was #1 :)

Well crap! I went to order the high top throttle cables from Economy and they are out of them. Crap!

Of course, my '75 had the tall caps on the carbs. Because they are so tall and difficult to get out when working on the carbs, I switched to low tops with the curved adjusters.

I have the low tops with straight adjusters as well. Would you go ahead and order the new cables that they have and change to the straight adjusters? Or would you just wait until the others come in and keep the curved adjusters?

The ones on there now work, I just don't care for them and the amount of adjustments they have left.

me? id order the short tops cables  and revert back to short top carbs if you gave the tops and slides to match
