I always thought that real HL's had a 3 valve head?
Is that true or was it only a few special ones?

[firko]

Is it just me or is it the more knowledge you gain on the details of old bikes the more pathetic you feel 

It can be a curse .

Wonder how Sten Lundin and Torsten Hallman would feel about all these jacked up wonders

Every time I see an HL with 43mm forks and long rear shocks I ask the same question. They are such a cool bike in their original stance.

A small number of 3 valve heads were produced tested on Bengts race bike as a skunk works R&D project connected to the whole HL500 deal.  Finally the moulds and the heads went back to Japan to disappear.... except for 1 head which is still in the Aberg garage from all accounts, we asked Bengt.

Daytona the Japanese perfromance house did high port big valve head for SR500 racing, price is a little ouch though.

Not this old Chesnut again, yes true the short travel bikes suit Hobbit size riders.  'Stance' sounds like something they talk about in Live to Ride magazine.

Has anyone ever noticed that this bloke has advertised the same stuff on Marks Swapmeet every week for literally months and never seems to sell anything? He's had the same swingarms, old Jap 4t engines and bikes for months. The late Bob Neilson warned me to never deal with him, I wonder why he bothers?

I just tentatively sold much nicer White Bros one with the original stay arm that holds the brake cable for $700 NZ and turned it into DR400 White Bros arm.

Anti-squat, like lots of good things, can be taken too far sometimes.......

its a lot easier to get on when your bike is lowered right ross 
there was a lot off swearing going on that day

[Tahitian_Red]

The guy with the HL is looking for an air-box for the bike.  Anyone know if there are any reproductions being made?

He said he found it listed as a trail bike. 

[paul]

you will have to ask him if it will fit a pro fab frame

[GMC]

So, I would guess this is an early ProFab

Actually I reckon it could be a late Profab.
Compared to this one from 77, TR's frame has a different bend in the backbone tube and the shock mounts are higher in the frame, Possibly to fit longer shocks for more travel.



If anyone really hates the long travel versions that much then maybe you should send off some angry e-mails to Rick Johnson & Ron Lechien

If I remember correctly my sidecovers and exhaust fit the Profab frames but the airbox doesn't

[ola_martin]

Profab has a different hanger-bracket for the airbox than the NVT.

[ola_martin]

One way to spot the difference on the NVT compared to ProFab/Aaberg is that the frame is much closer to the engine on the ProFab.
Look at the front engineplate.
