i'm trying to keep it period correct in mechanical terms
period correct would be the sprag or centrifugal clutch
used on gocarts and minibikes
use a return spring for the throttle to go back to idle
or the clutch will stay locked up
here is a better view of the carb type you can use https://www.ebay.com/itm/43cc-49cc-Carburetor-Carb-For-X1-X2-X3-R1-Z600-CATEYE-X7-FS529-FS509-X6-509-1/162304919857?_trkparms=aid%3D444000%26algo%3DSOI.DEFAULT%26ao%3D2%26asc%3D20190129125700%26meid%3De06fce57ccd54879a34c14867262d038%26pid%3D100752%26rk%3D2%26rkt%3D12%26sd%3D162310815535%26itm%3D162304919857&_trksid=p2047675.c100752.m1982
very good views of the throttle and idle screw
what about a briggs and stratton small block vanguard v-twin, it's ohv but its also a bit more compact
plus i can get a cool chrome cover for it
give me a link to the engine
they have a 13 HP and 16 HP version of their smallest engine
479cc
only a few slight modifications and it could be used on a bike
briggs and stratton sells a bare block kit version of the engine
for your size bike anything over 8hp is overkill
i figured as much, the v twin tho seemed nice and compact, everything in one spot and the covers on them look vintage as hell if they were chrome.
but i'm also cool with the 5 hp shortblock flathead raptor
if i go with the raptor likely i'll paint the block red and get an aluminum cylinder head
most high performance engines have that type of setup
maybe i'll get a ricardo head for it an up the compression ratio a bit
7.9:1 maybe?
cylinder head is already aluminum just painted. you can change the compression ratio by head gasket size.
cool, yeah 7.9:1 seems like a safe ratio for a single cylinfer flathead, some ford flatheads were 9.0:1 but most were at around 8.0:1 to 8..4:1
better results with 8to1 with high octane gas
stay away from 85E stuff
i told u so -
Whew☝
