Alky has an extremely slow burn rate, 7-10 degrees is very common.

Lol BTW, your domes, port and pipes aren't working well together if the engine wants 10* advance on gas, in my opinion.

No, with the rise ratio regulator it gets 21psi fuel pressure at 15 psi boost. I am quite positive the velocity increase through the carb at 10k and 15psi is outrunning the volume capacity of the needle/seat

As you stated in your original post, it won't perform as well as it will once you get some alky domes.

Should be just fine

Running 32mm TM Mikuni setup for blow through. Good 1.25 miles lol

Well, this one seems to work incredibly well as long as the bowls have fuel. Not a pump around. Using an efi pump with 1:1 rise regulator and return to tank. Going to do some magic to add fuel under boost. And you talk like I dont know you've had a good running turbo bike lol.

No records this year, but was a fun and learning experience. Smoked the left piston 1.25 miles in when it sucked the left bowl dry. Going to make some one off custom upgrades to the fuel system to keep this thing fueled. Guess I will update in a couple of years when we can get back on the salt.

Lol Green! This would make a really fun dune engine! When it hits at 8200 rpm and jumps from about 5psi to 15psi you better hang on! Would love to try this bike out with some more reasonable gearing. 2.68 primaries and 19/32 sprockets makes for a sluggish 65mph first gear lol.

It's been a fun and challenging build. 350cc serval on methanol at 15psi boost. Biggest challenges were building a return type fuel system for the blow through carbs and designing an oiling system for the turbo.

Built this in 2013. Set a daily record, headed back to Bonneville to claim it back. Thought you'd enjoy some pics. Brandon

If you feel they're worth it they can be plated. Millenium has done sleeved cylinders for me a couple of times

At 5k' you can go with 19cc domes on pump with a conservative chamber design

If you're going to run a staggered transfer arrangement you'll have much better luck opening the primaries first then secondaries and boost last. Make sure you're exhaust crown is not too flat and the ports are perfectly symmetrical. -B
