I am wondering what modifications are there on a bonneville. I have the Bonn carb and it sure kicks hard. Was there a compression difference?

Do you mean it is hard to kick through, Arley?Originally posted by Arley View Post
Or just hard to start?
The compression difference is pretty subjective to one's foot.

I believe the differences are cams and lifters, carb,ported cylinders,pop up pistons with thin rings,relieved heads,magneto.
I think the comp.ratio is probably higher but I have no reference off hand and Im not sure if a 74 bonn and 80 head are the same.

Mine will stop me I weigh over 300. I have to watch and only kick at the 9 o'clock if I try at the 10 or 11 I can't follow through. It screwed me up this summer because it stopped mid strokeComment

dont worry the more you ride it the easier it will kick over as the exhaust valve burns.

That is one way of looking at it lolComment

With 28 tooth mag kicker gear and camming it has a moderate kick then a hard kick. The colder it gets the harder it is to kick thru. Always make sure the kicker is lubed.Last edited by tomfiii; 12-20-2019, 12:27 PM.Comment

Gosh Arley,
Does it kick through easily with the plugs out?

Both std. Chief rocker ratios: .81:1
Both Bonneville rockers: .86:1
Yes, the lobe is taller than the lift
Bonneville Linkerts are the same 1-1/4" (nominal) throttle bore, but the venturi is 1-1/8" vs. 1-1/16" for std.
There is also a different main nozzle called out.Comment
