Topic: Let's Build an F/X..!!!

thats kinda what i was thinking just because the tires are 8 in wide, but you know how many different rims there are, thanks again

[George Herrin]

Even the tire manufacturers recommend running wider rims on rear than tire. The idea is less sidewall flex. More tire on the ground and a more sure feel instead of a wiggle or loose feel from the sidewalls flexing. Now on front most manufacturer recommend same size rim as tire. Go to a kart track you will see tires on as much a 2 inch wider rims. It helps with stagger also by giving a different overall dia by stretching tire sides out.

Well I rolled it off the rim twice now and that can make a hairy ride..

I have not found tubes to direct fit a 12 x 8 -6

I like the sidewall stance, but not the tire pressure I need run to keep them on the rim..

If I could find tubes I'd stay with the wider rims

[nic_hayes]

I'm not sure if they make tubes for those tires squidd, they are a tubeless tire but you could check burris's website or maybe they have a number you could call, later

I know I ain't the first Kid on the Block to have a set of these.. but purt near...


Sweet little items, excellent fit and finish and the cover still fits...

Gonna be the start of one solid lightweight high revving little OHV build...

[George Herrin]

Quite honestly Randy you were the FIRST one to have them in hand!!! Jed was the first to have a set of twins he was running them at Ooltewah, and he now has them for the  single also. Use your lash caps!!

Cool...

Use your lash caps!!

Good thing you mentioned that... Glad I didn't toss them out yet... 

[George Herrin]

The lash caps give a broader base and helps ease the stress on everything and spreads the load out more evenly. briggs had SOME good ideas.

[Mowindown]

Does the V-twins run lash caps?

[George Herrin]

No they don't the biggest reason for them on the single is the long rocker ratio. The twins are much less.

Now i'm really confused!!! what are lash caps? I opened my stock 14.5 ohv single and don't know what you are talking about. Do they come with the new rockers??
help..... pic please...... never mind i found out

[Mowindown]

If you look on top of the valve stem right where the rocker arm makes contact with the valve stem you will find the lash caps.  Most of the time they will come right off with the rocker arm out of the way.

yeah sorry, (man i feel stupid) i remembered when i rebuilt my v-twin, i didn't see any, and then i remembered that on the singles they do.  also George, how much hp do these free up? or can you even put a # on it, or is it just so that every thing moves easier, less friction(?)my engine is a 14.5 ohv briggs Don's cam, block, head work,etc.(no crank,rod, or piston yet)

You can see where the caps both spread the load across the roller on the rocker... but also downforce is split over valve end and retainer to spring.



The extra height also brings the rocker geometry in line... an 1/8" off can change cam and lift effect.

hey thanks, were you just using just one to show me the difference, or do you just use one?
