Unfortunatly i didn't take many, it was a mad rush to get it ready for the begining of the season
But this is how i got the rolling chassis, it had been crashed at Lydden in the 80's then left in the back of a garage

https://i237.photobucket.com/albums/ff98/Higgsy_photo/Hybrid/DSC00073.jpg
Just about got it in one peice with borrowed pipes and unfinshed tank for the YPM stand at the Ally Pally show
https://i237.photobucket.com/albums/ff98/Higgsy_photo/Hybrid/DSCF0069.jpg
Managed to blow the engine up at Oulton, so i bolted in the motor I'd bought from a fellow racer that morning and went out on it, I'd bought the engine knowing it was tired and needed a rebuild, still did ok but it was seriously down on power.
Rebuilt the original engine and at Brands GP it all came together and I got the first LC in the top ten for quite a few years
https://i237.photobucket.com/albums/ff98/Higgsy_photo/Brands%20GP/28707_118022198236813_1025181297872.jpg
It's been through quite a few changes since the original build, the engine is now Bob Farnham tuned and fully sorted, and two seasons of racing have taken it's toll on the cosmetics.
Pat Herron, who can ride a bit , got a second on it in the Paul Hogan memorial race, which cheered me up no end!
This is what happens when you rev a powervalve engine to over 11000 rpm!

I've got a YPVS as well that's under construction atm.
It's a combination of the swingarm and the swingarm frame pivot that induces the most flex on the LC, I can't brace the frame under the regulations but I can change or brace the swingarm
We ran some rudimentary stress tests and came to the conclustion that the stiffer aftermarket swingarms would transfer the stresses to the swingarm piviot and onwards to the frame. So hence the bracing between the rear swingarm triangle. It was an attemp to equalise the flex a bit more. The standard unbraced swingarm is very weak and you can bend it with your hands!
I really wanted to build and race an lc, having felt I missed out back in the day, putting the YPVS engine in was an attempt at easier power and more reliability. I ran a standard engine for the first season, managed to get it near the power limit of 59hp on the Bemsee dyno with just carbs and pipes ____________________ RD350LC/YPVS Race Bike and enough bits to start another one! - RD350YPVS Race Bike - TZR250 Race Bike - ZX9R - ZZR1400 project - DRZ400SM - RD400 - TS100 - TY250 - More info @ www.waveracing.co.uk or www.ypmrc.co.uk |

The motor in there at the moment:
Bob Farnham 'Sean Emmett' tune on 31K Barrells, stock F2 bottom end, crank has TZ flat cage bearings, Bob's one piece reeds in stock cages, XS750 clutch with three TZ750 springs
Martin Johnson Hydroformed pipes with DTR TZ end cans
Keihin PWK28 (ex KR1s) Carbs
Stock F2 stator, shaved rotor and F1 CDi, stock F2 powervalve controller
It would make a lot more than out 59hp ceiling if we did some exhaust port work, but the idea was to get it to drive out of corners. Works very well The engine is about as much as the chassis can cope with realistically
I agree, the powervalve is a bit of an ugly and heavy beast, the LC is much prettier  ____________________ RD350LC/YPVS Race Bike and enough bits to start another one! - RD350YPVS Race Bike - TZR250 Race Bike - ZX9R - ZZR1400 project - DRZ400SM - RD400 - TS100 - TY250 - More info @ www.waveracing.co.uk or www.ypmrc.co.uk |

That's a great spec, 59bhp is still alot for such a light bike, and as you say it retains driveability. One of the best bikes I've ever ridden was an RD400 with 440 big bore and mild porting. It pulled from idle into the midrange like a good 4T, then fucked off like a good 2T - best of both worlds. ____________________ 18:54:48 Rob Fzs: jews don't give away stuff for free

RD400
I've got one of those as well! Stan Stephens fast road tuned, 420cc on Allspeeds. Far too much engine for the chassis without a doubt
That's on the project list for this year, haven't ridden it for at least 8 years
Back to the LC engine, it's all about drivability, although it's a race engine it would make a hell of a road bike! It will pull from 5000 then gets a real shove on over 9000. The hp figures don't really tell the story of how it goes. You can easily over port two strokes, the pipes and carburation is more important to how the bike performs and drivability more desirable than peaky top end power IMO

Ah, beauty is always in the eye of the beholder m8, just as it should be. I've got a m8 who's mad about GT380's for some reason, I think they were bloody awful back in the day and probably still are, but he's convinced they are the dogs nuts. He's got four of them Each to their own as you say  ____________________ RD350LC/YPVS Race Bike and enough bits to start another one! - RD350YPVS Race Bike - TZR250 Race Bike - ZX9R - ZZR1400 project - DRZ400SM - RD400 - TS100 - TY250 - More info @ www.waveracing.co.uk or www.ypmrc.co.uk |

Unfortunatly not m8, lost all the last rebuild pics when my old pc hard drive died
It's a 400D on an S plate, I'm the third owner, matching numbers, guiglario seat, tomaselli headlight mounts, LC front guard, cut down rear, Allspeeds, rear sets, Micron brace, I've owned it since 1989 after buying it off a m8. Did have Dream Machine paint, but that needs doing again now and the stickers were wrong anyway It's proper old skool and it's going to be staying that way!
I will be rebuilding it after I've sorted some bits out, but it won't be until later in the year, too much to do, too little time  ____________________ RD350LC/YPVS Race Bike and enough bits to start another one! - RD350YPVS Race Bike - TZR250 Race Bike - ZX9R - ZZR1400 project - DRZ400SM - RD400 - TS100 - TY250 - More info @ www.waveracing.co.uk or www.ypmrc.co.uk |
