'Building' a bike - help please

**n0regret5** · 29th November 2009, 14:16

ok so i have a plan. i own an FXR150 which was in an epic crash thanks to some cager twat face deciding to do a u-turn on a median strip on a busy auckland road outside the airbase where my brother was riding to work, totaled the front end. ie forks are fucked, fairings are only bin-worthy, still have lights and electronics all sweet.

my question that i need help on is, how much legal work is required if i want to make a street legal bucket racer? i want to take an old style frame like from a cb350, single top tube steel cradle kinda thing, and biff the engine in that, get some new forks, chuck all the wheels, brakes and electrics into this frame and make a single banger cafe-racer style bike with modern running gear...

frame will be VERY lightly modified, maybe do a monoshock conversion, will be modifying the rear subframe if it doesn't suit what i'm after etc. so shouldn't need certing for welds and stuff cos they won't be structural (if leaving dual rear shocks), just need re-vinning with a new frame.

any help would be GREATLY appreciated - i have no bike at the moment and its driving me up the wall

ol cb 350 will weigh too much...

Ummmm, FXR150s are a monoshock.

Thats just what I was thinking to start with but now realise he is talking about butting his FXR motor into a CB350 or other simular backboned frame that may be twin shock.

Personally I think you are in for a world of pain regarding certifications etc, and surely just for the repower with a different engine it would need to be certified. Any structural frame modifications will need to be certified and I would be very surprised if you would get a VIN without them, especially if you were to do a mono shock conversion. Also personally for the amount of effort you are talking about for a FXR engine, you would be way better off with somting else. But hey what ever floats your boat.

Please note all advise is my own opinion and you should seek advise from a proffesional for clarification.

Now I am going to be opurtunistic (please dont take this as me trying to talk you out of anything for my own benifit) and if you do decide to go ahead with this I would be interested in what is left of the FXR frame. And if you decide not to go ahead at all I would be interested in what ever is left of the bike. Will send a PM

C'mon guys read before you type ;-) I know fxr is a monoshock, I was wanting to dump the wee engine into a new frame. Have found an rg250 frame that I'm eyeing up, wouldn't make any mods to the frame at all bar adding a few bolt on engine holdy bolts. My bad, it's late.
As for the frame I think my bro may have hacked off the steering head but I'll check it out and get back to you...

LOL. Now that's funny because I just abused two people for not reading another thread properly.

As you were.

I think you will spend a grand getting that LVV certified. Better to suck your money out of the cager who caused the problem, and start from scratch with a road-worthy bike, and stick to non-cert mods.

took the guy to court cos he fucked around so much (sorry, my brother did - he was the one riding it at the time), he kept saying it wasn't him and denying it was his fault, got dicked for a long time but eventually got something out of it. not alot..seems typical. when i got t-boned by a mitsi triton on my TL i got fuck all for it, lost a toe and my favourite bike by far, and i just found out the compensation that was paid to me over 18 months at $40 a week, the guy recieved back in a lump sum from his insurance company.
but thats another story...

so you reckon dropping the engine into an rg250 frame and getting it cert'd wouldn't be worth the bother? if not then i may just sell the engine and various OK parts. provided my bro wants to give it back to me (he was supposed to buy it from me and still owes me for it, 4 years later)
