I would like to hear and see some of the ways people have fixed the problem with the tail cracking from seatstander circles on the F4i.

post up pics if you got them.

 

zipties? u start riding the honda already?

 

Fiberglass the back side!

I've only put 2 layers on mine, but next time I paint my bike, imma throw another 5-7 layers on it..

It dosen't have to look good, just brace the inside of the tail real good :YEAH

 

+1 to laying fiberglass.

Also put a 1/2" piece of wood behind it with some foam over it

 

Okay sounds good, do I just paint the fiber glass on, spray it on, or lay it on?

Not yet, waitin on that flywheel. Zipties dont solve this problem unfortunately.

I was thinking somethin like that. Do you attach the wood to the subframe or the tail?

 

this has been discussed. here's the link..f4i-tail-bracing

here's what I use with foam from a knee pad.

 

i stuffed my air ducts in there and it seems to be working.

 

^^^^^
Thanks for the pic and thread. Would you mind expanding on how you place that piece of wood with the foam. Do you cut it to fit between the rider seat and the passenger seat? Or does it connect to the tail?

Thanks.

 

I use the lay it on type.

wood to the subframe.

 

cut to length, lays up against those triangle metal pieces on the subframe, i just drilled a few small holes and ziptied it to that. then used 3m adhesive spray and put a piece of 3/4" foam from the craft store ...

 

Instead of real fibreglass which can be a bastard to work and the resin is some nasty **** on your skin you could use fibreglass reinforced bog, just get a rasp on the back side of the plastics to rough the surface up and then lay your pick of glass down, whether is be real fibreglass or the bog kind both will benifit from a non smooth surface to stick to

 

fiberglass isn't that hard as long as you don't drink a 12 pack before ******* with it


Just get some gloves, fiberglass resin, fiberglass mat, and a paint brush from walmart

Cut strips of fiberglass to around the size of the part of your tail you step on, paint the resin on the mat, apply it to the tail, use your glove covered hands to smooth it out..
repeat as many times as you like.. Once you get 5+ layers on you could jump on it and not break it

Im thinking about doing my whole tail.. That way I can continue to scrape with no round bar :YEAH

 

i fabed up a 1/8 inch piece of steel plate that i now stand on an tossed some grip tape on it...
i have it off my bike at the moment ill see if i can get some pics.
i bolt it to the seat bolts.
it works great!
no flex!
mines over engineered. but it aint breakn or flexn... i have seen simple'r designs thou.
if anyone needs one for a f4i...
i am gonna make a few for some people...
i can just add some to that list...
ill try an get pics up tommorow.

 

Cool, thank you everyone for the advice. Im gonna go for the fiber glass idea. This dude O-dog from down south did the metal with grip, but I wasn't feelin that, looked ugly and would eat my pants alive.

 

haha ya i ride with O...
were swapn engines tonight at his house haha
ya i dunno.. i jus like how solid it feels
an knowing it wont break...
how would it eat yer pants?
you dont sit on it really...
i havent had a problem.
im goin to make a more low profile one for anthony an see how he likes it...
and im triming mine down today too..
fine tuning the feel an size...

 

Are you cereal, because mine have just been laying in a box for about 6 months. I'll go stuff em in right now.

 

get a rr tail

 

make one out of T6160 aluminum

 

actually it's 6061 t6 aluminum that you want... but **** that... wood works just fine and is EASY to make.

 

heard sick innoations was going to make a thing to stop this problem!!!!!

hard to see but look at the red plate inbetween my seats
