Tech how2: Rear seat cowl done PROPERLY!
32 Attachment(s)
Right , I promised to do this how2 guide ages ago but I've only just got round to finishing the cowl today. Just finished uploading the pics so here goes....
Basically not long after purchasing my FS1 (UK F4i) I bought a Powerbronze seat cowl. I chose the Powerbronze brand as my rear hugger from them had been an excellent quality item and a superb fit... the seat cowl however was not! This is the purchased item: Attachment 40260 And this was the flimsy fitting kit supplied with the cowl which had to be spaced out with numerous washers as directed by the instructions: Attachment 40261 Attachment 40262 Yes it fitted the bike , but my problems with it were.. 1: it had a giant bolt right through the most visible part of the cowl (the top) which completely ruined the smooth look. and 2: if you put any weight against the cowl whilst pushing the bike the cowl would lift and move literally inches across the bike which was risking damage not only to the flimsy cowl but also to the bike itself. Not good. Attachment 40263 So... how could I remedy this I thought to myself? My immediate thought was to buy another rear seat from a scrap bike and make a hybrid affair from the cowl and an actual Honda seat , so thats exactly what I did. I sourced a seat for under £20 from a Honda breaker: Attachment 40264 Then I set to work dismantling the seat and removing the cloth and foam etc... Attachment 40265 Attachment 40266 Next step was to fit the bare base to the bike and then test fit the cowl skin over the top to see how much modification would be required: Attachment 40267 Attachment 40268 There was quite a gap so I set to work marking and grinding the plastic base away until it mated nicely with the cowl skin giving a neater panel gap: Attachment 40269 Attachment 40270 Attachment 40271 Once a decent panel gap was achieved I fastened the base down to the bike and then attached the skin to the seat base with wood screws , these were temporary merely to hold it in place , the screws were tightened until the correct gap was achieved along each edge. Attachment 40272 Attachment 40273 Attachment 40274 with the cowl fixed to the base the whole lot was removed from the bike to be permanently bonded together , this was done by plastic seam welding right around each edge of the base. The welds were then sealed in with fibreglass resin on each side.The seat cowl was then filled internally with expanding foam. Once the whole thing was permanently bonded the wood screws were removed. Attachment 40275 Attachment 40276 Attachment 40277 At this stage the holes in the cowl for the original fitting kit etc were permanently filled and the whole thing was smoothed and primed: Attachment 40278 Then I needed to address the issue of how the foam pad was to be attached , as the seat cowl was now much thicker than before and also there was no room to get in behind to bolt it on. So I decided rather than use bolts I'd use M6 studs in the seat foam as I could easilly get a nut on the underside of the cowl despite not being able to fit a bolt the other way. M6 studs were sourced from an Italian scooter manifold... Attachment 40279 Cut to length and away we go... Attachment 40280 Attachment 40281 Attachment 40282 Attachment 40283 Ready for paint , on with a bit of colour (R-158 , Winning red) Attachment 40284 And then build her back up: Attachment 40285 Attachment 40286 Attachment 40287 Cowl next to standard seat: Attachment 40288 And on the bike , nice fit and feels very solid. Very happy with the result: Attachment 40289 Attachment 40290 Attachment 40291 |
That looks incredible! Great job!!!
|
Awesome write up, and great end result.
|
Thanks guys!
I was so disgusted with the poor quality of the original item that I thought a write up with plenty pictures was a must , just to point others in the right direction if they were unhappy with theirs. |
Now that is dedication to a vision! Excellent work!
|
Wow that is awesome. Very impressed.
|
Excellent work and write up. Thanks for posting, this is something I'm considering.
|
that turned out great man, nice work and nice writeup. your idea was better than the original cowl by far. funny that the company didn't do something similar to your idea so it was ready to mount with little to no problems.
I like the way you think, very creative. |
Thanks for the feedback , very much appreciated.
Yeah you would think that for the price of the kit (£90 uk pounds when full price but I bought it on offer for £60) they would have put a bit more thought into it. It's quite annoying to think that the only useable peice of the kit was the outer skin which is little more than a peice of formed plastic which would cost under a tenner to make. :mad: |
great job!, in addition i have found it extremely difficult to find a cowl for the f4i with the bannana seat like my 04 so i bet they would not be cheap if i did.
