Johnnylevi, your bike looks great!  Lot's of really good info in your thread too.  I really like the blue stripe!

[Johnnylevi]

spark advancer is what I think its called. Sorry for the confusion sees haha

This is what I mean

Thanks for the info on the CBR Coils.  Was looking at the Dyna 2000, but sound like the CBR coils does the trick.

[Johnnylevi]

Yes the CBR coils will definitely help, but I found that the 900 spark advancer has also helped tremendously with my bike. I had a sputter in the 2-3k range and now after installing this I do not. If you can get ahold of a MG5(cb1100) advancer i hear they work even better, but for $12 you cant really beat the 900.


Upgrades Thus far:
F3 CBR coils
Procom igniters
438 spark advancer from cb900
front SS brake lines

Still to go:
900 cams
823cc kit... probably more... haha

[FastCletus]

to go
engine tweaks

Here are the procom igniters

http://www.ebay.com/itm/Honda-CB650-CB750-CB-650-750-Igniter-Procom-Electrosport-Brand-NEW-Updated-Mod-/111097772697?pt=Motorcycles_Parts_Accessories&hash=item19ddf17a99&vxp=mtr 

link directly to their website
http://www.procomeng.com/product.php?cat_id=5&brand_id=1&model_id=137

My understanding is that they can build a larger spark faster.


I think the advancer I posted is still up for sale. Its like $6

[FastCletus]

is this what your talking about?

Yup the specific link is this, but that part is still correct just more expensive  

http://www.ebay.com/itm/251287938171?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

And no you do not need any other upgrades for the coils to work, in fact you will notice a HUGE difference just with the CBR coils. I have noticed an even greater difference with the spark advancer, coils, and igniters. I use the choke to start the bike and then push it in and the bike stays steady.

[FastCletus]

Sold.

Here's how she sounds with everything done.

Still have to do a valve lash... but i really just wanna ride this thing..

[seestheday]

Doing a valve adjustment is easy



Weird, I don't know why that's not working.  Embedding videos has always worked in the past.

[FastCletus]

That's the speed I want my engine to tach to. That's awesome thanks for sharing

[Johnnylevi]

hey sees is it necessary to put some assembly grease on the cam lobes before sealing up the case again?

[Johnnylevi]

No problem! Just glad the thing runs! haha it will go to 10k easy, but its like 100 here at 10 in the morning so i wanted to get back inside.

[seestheday]

I did because that is what the fsm says, but I've heard that it isn't necessary. Just make sure that there is plenty of oil in there before you start rotating the cams.

Damn, she sure sounds good. Can hardly wait to get mine to that point... Thanks for the motivation and Congrats!

[shinyribs]

It really does sound good! I just love the way these older inline fours sound compared to the newer ones.

[Johnnylevi]

Hey guys, so much to my own disappointment... I am going to have to sell my bike. I'm going into the fire academy next semester and won't really have much time to work and I'm on my own so... I need a bit of extra cash. I'll still be floating around on the website and hopefully you'll see me with another build thread in about 6 months  

[Hoosier Daddy]

DUDE!!!
