yep. i always found it funny watching mdb starting up his big horsepower bikes on one, but now I know why he does it. They dont vibrate all over the garage floor when they're up on something cushy.:thumbsup:

The engine sounds good.

 

[MB165]

Sounds good, you and I been doing the same thing this weekend, I fired my build up yesterday for the first time. Cant wait to put the clutch on it and terrorize the neighbor hood.
:evil_laughter:

Methanol or gasoline?

Sounds good, and I like the exhaust.

 

[mmisterbungl]

Oldschool, gasoline.

Not so much.

100LL

100 octane leaded AV gasoline.

Please do not use Spannish.
I had to look that up.

I have some concerns about 100LL. Not the least is the high level of lead. Mostly deposits and the additives they use fouling my surface gap plug.
Lead isn't just bad for people the things they add to the fuel to scavange and reduce deposits is bad for engines.

I am going to run a blend of 92 ( or 94 if I can get some close by ) Octane UL with 10% Xylene and 10-20 % methanol ( provided this does not require a co-solvent to keep in suspension ). Might resort to mixing in 100LL to help boost that.

I hope based on the last engine if I keep the timing around 26 and adapt some better shrouding to cool the head ( and the cooling effects of methanol ) I might be able to run more pump gas in the blend.

I don't want to have to flush my fuel system every time I use it because of the methanol...

haha, I made sure to become very close friends with all the surrounding neighbors right away when I moved here in March. So far they know me as the big kid riding around little 4hp bikes with my son that make minimal noise. I'll probably be taking this one out of the neighborhood to ride it.:wink:

Thanks Mark!

Have you run this engine under load yet?

I had troubles Mark.
might have been timing related but premium UL was not doing it for me 14cc head and FT piston 11:1 compression

No not yet, that was the about the 2nd or 3rd time I had fired it yesterday. I'm tempted to run it but I don't have a rear brake on the bike it's mounted on right now. :crying:

 

[jprice]

Not so much.

That's our old carb. We had Larry build us it, but we didn't get on with it at all.
Sticking to Mikuni Flatsides, looks like you've got it figured out though. Maybe it was just our British weather/fuel...
