    BUT... it should run fine for the RWC and then you can put those pipes back on.  They may ping you for the really ugly aircleaner cover though.

     

    Are those 'smokey' lens covers on your indicators?  They may not meet RWC needs.

    I'm not seeing a belt guard either...

    rides well ,

    thats an old pic i have had the body made and i still need to do a bit for a roady but any info would be great

    i did put up and subject about the rear end and had no response from that but i was wanting to know  i brought the rear trike end from america and when i got the body made the guy there said i would have to get a $5000 engineers report on the modifications and i dont understyand as the part was a bolt on with no modifications done to the frame as such.any advice on that would be great and if any one has ideas on things i will need to do or change thjat would also be great .

    Yeah....it's just that it's a hypercharger by kyriakin and the a generally given a hard time cause they look like chit etc. other than that it will be fine on the road.

    An S&S teardrop would work well on that bike I recon.

    A lot of folks remove the belt guards so it's your call. You may need one fir a RWC though so leave it on until all that stuff is taken care of.

    It would be worth chatting to Walka here and popping into VPW for parts etc as they deal in rigid bikes all the time so they might be keen to guide you if you score parts from them! They are a forum sponsor and have some bloody awesome parts in their showroom and online,

    I'm a bit late, i don't think bike will run lean with stock pipe i think it could run slightly ritcher, but i feel the stock pipe with trike rear would give more TQ. just leave aircleaner as it is just do stock pipes. if you get pinged for air cleaner put stock on.

    Also i notice you don't have a steering damper, i think you need one with a Trike !!

    Have a guy in town who has a trike rear that looks same, but he has old hot rod steel skinny wheels with moon hub caps think his would be lighter, it's on a new 72. looks good he has stock pipes with slip on's & has steering damper, he rides it a lot & he is 90 years old ex speedway side car racer & he still rides hard!!

    Personally i think stock pipes with aftermarket slip on's would perform better than the pipes you have on as would have better torque a good 2 into 1 like supertrapp would be ideal as can tune sound plus they can betuned for more Torque & it's Torque that thrusts you forward not HP.

    Good Luck, what state are you in as different states diff rego laws , also note your rear trike gaurds, guy in town as i said has skinny wheels about same as stock rear sporty wheel and he has a stock sporty rear gard on each trike rear wheel so looks more like factory custom, yours would need engineers report in some states.
