Husqvarna / Pipe/carby wanted for '82 XC or WR 250.

« on: December 09, 2007, 05:56:40 pm »

Hi Husky folk,
The bike I've been racing in EVO has what I've been told is an XC motor.  It's disappointingly peaky and doesn't really grunt out of the corners very well.  A bit like riding a 125- you have to get it revving, and after years on Can-Ams, it doesn't really suit me very well.

I thought that the motor might be a bit clapped out but I've just taken the top end off and the piston is pretty new (looks like a Wiseco) and the rings are not worn.  So I'm thinking it might be either:

1.  The pipe.  The pipe looks very similar or even identical to one that Albert has on his bike- and i think his is a CR.  The only thing is that mine has had the header section reworked and it may be that it's a little shorter than stock.  Does anyone have a stock WR or XC pipe that they want to get rid of ?

2.  The carby.  It has a 38mm flat slide Keihin on it, that came from a late 80s KTM.  And it carburates fine- starts well and doesn't blubber etc.  But I'm thinking that maybe a 32 or 34 might make it a bit more rideable on out tight MX and grass tracks.  Especially for an unfit mug rider like me.  Has anyone has any experience with fitting smaller carbs than the 38 ??  What did they have stock ?  Does anyone have a stock smaller carb they'd swap for the flat slide ?

Any other thoughts on how to get it to pull from down lower in the revs ?

Thanks in advance,

Nitram

Does anyone know where I can get the universal-type ordinary oval green racing number plates  ?  They used to around the shops in packets of three, but I can't seem to find any.
Thanks,

General Discussion / Re: All time great bikes?

With all due respect for the opinions from the many highly respected campaigners contributing to this thread  , I have two things to say:

Firstly, it's pretty clear to anyone with eyes in their head that there is ONLY ONE truly great all-time great bike in the great grey mass that generally passes for VMX bikes, and here's a picture of one that I noticed in my backyard on the weekend   




Downsides ?
    - some would say.... bog ugly....but then that's in the mind of the beholder.  I personally find that the style sort of grows on you.......... after a while.
    - the suspension is pretty average.  The pre-'75 boneshaker does just that, and in my experience a stock '80 PE175 steers, jumps and slides nicer than a '80 Can-Am with it's Marzocchis and Ohlins.
    - they bristle with innovative thinking and novel ideas, most of which don't work.  Whether its the radical and complicated adjustable steering head bearings, the rubberised shim-adjustable swing arm pivot, or the lashings of magnesiums castings in the crankcases and brakes, the reality is that I spend most of my time figuring out how to get standard Jap parts to fit.

Upsides ?
    - They go like an absolute shower of shit !    When the gate drops the Can-Am drives forward like nothing else -all the way through the revs- and the other bikes front wheels disappear backwards at a very satisfying rate !  For a mug punter (like me), it's a huge advantage, and that's why they sold them by the truckload in the States in the mid and late '70s.   


Secondly, in regard to the modern four-stroke thing:
    - My mate just bought a second hand '03 520 KTM.  I went for a ride and could stop smiling and raving about it.  Just perfect ! As well as being the massively grunty from way down low all the way through the revs (bit like a Can-Am actually  ) with sensational handling, braking, sliding and jumping, it's also capable of being toodled along to enjoy the scenery, and despite the awesome performance, it doesn't dominate the average rider the way really sharp big two stroke can do. 
    On the way home from it's first decent ride the big end shat itself and the amount of slop in the rod, he was lucky not to have written off the piston/barrell and the head as well.   :'( 
    I don't think I agree that the modern 4 strokes will be the death of the industry (that's pretty extreme !),  but it's pretty clear that the next generation of VMXers will have a much more expensive task to keep these modern 4 strokes on the track than we have with our '70s and '80s two strokes.  But then.......... isn't that their problem ?

Cheers,

Nitram
