i've done quite a bit of research online and asked a good handful of trusted engine builders i know and Glyptal WILL go in all my builds from now on. this stuff has been around for YEARS, and when properly applied, it'll last a long time and give good results. This stuff should of been applied from the factory!

I'm going to be bringing my nephews 750 stuff home in a week and he's got an 836 that I'm thinking I'll run in The Beast for next summer while I build my "F" motor. Giagntic amounts of inspiration from this thread, thank you!

I picked up a hella H4 headlight conversion so I can run a brighter headlight and ditch the sealed beam.

Did you have to install any kind of a relay to ease the load on your wiring harness?

I ran an H4 in a Cibie lens for as long as I had a 750 (long time). Stock no relay, but a relay would've helped I've learned since.

Really looks nice!

Funny how the cost starts creeping up when you start buying engine stuff, huh?

It can be $6,000 when your done. Not kidding.

But basically it IS a brand new motorcycle for $6 grand. Not bad.

BTW...I see you do very good work.
What type of sealer did you use when you put the case halves together?

tweakin · « **Reply #530 on:** October 11, 2011, 05:12:51 pm »

I did not and have not had any problems at all.

Lucky, I had great success with Yamabond 5 when building my 836 engine last year so I used it again.

How would it have helped? I have an H2 bulb in a vintage lens...and I was told a relay would be necessary...just trying to sort that out.

No its not necessary as I and others can attest. Just install it and go. You will still get more light even without the relay. But if you do it, you'll like it even more.

All the current for the bulb goes thru the handlebar switch. Luckily, it can handle it, but you are stressing it. With the relay, the switch handles a much lower level of current, it turns on the relay which can then handle the higher draw of the bulb safely. Hence the light is much brighter.

I don't understand electricity other than to know what works and should be in concept. For instance the starter runs thru a relay for the same reason. The starter draws so much current if it didn't go thru the relay (solenoid) it would fry the handlebar switch the second you punched it.

After parking the 750 for il leaks I took to my 88 hawkGT. The guys at HawkGT.com were all gaga over relays. So i bot one from a guy that was kitting them out. Installed it and the stock headlight was a good 20% brighter.

Here's where i got the relays for my current project, horn (louder stock, or to drive bigger horns) and headlight.

True it can be done "Do it Yourself" but I need the extra help a custom kit can provide.

Here's their FAQs, a little hard to find:

HondaMan offers a few different relay kits. I am going to get the one he recommends for the cheap EMGO switches and probably the starter button kit.

Thanks B! I didn't know hondaman was making those. Just ordered up a few bits.

Branden, Tweakin'..good to see you guys last month at Vashon. Both your bikes looked great in person..absolute beauties.

Great seeing you to Larry. How did the bike show turn out for you? That is a really special bike you have.

Once I get my 915 engine build completed I plan on having you repaint my tins... Will be in touch.

Lifted out the 836 today in preparation to install the 915. Still have a few parts to come in but I am at the point of no return now.

brandEn · « **Reply #542 on:** October 18, 2011, 09:15:17 pm »

Just as an FYI he lifted that heavy lump out all by himself with no help! Crazy bastard.

I noticed he left the clutch out, cam gear, etc. Probably the alternator/rotor too?

That helps. I did too, But I still needed a hand.

But when i was 38 years old, physical peak, I could do it by myself as well.

OT: Liking his lift and tie down/wheel chock.

tweakin · « **Reply #547 on:** October 19, 2011, 11:45:05 am »

P90X..... ha ha

Pretty close to the way MCRider stated, no clutch, rotor ext. First the Gorden frame kit is a life saver. Thanks Hednut! I tie down the bike to my lift and elevate it so the engine compartment is about waist high. I put a board on top of a scissor jack under where the engine will sit so the engine so I have a platform in between the frame to set the engine on once it is lifted. This plateform also allows my to lift and lower the engine while installing the engine mounts.

I then set the engine to be installed on my floor jack and lift it up as high as it will go. Grab the engine, top and bottom end built and lift it into the frame. Really easier than I ever thought, and I have a bad back.

Man I need to get my Gordon kit installed. This is really making me want to get cracking on it.

Great work man, it continues to be an inspirational build!
