VMCC Rd2 bad vibrations on stock suspension KR1-S

[nzkr1]

Well after the first round I was ready to make amends after the crank few to bits. New crank installed and only started it up on the stand at home on Thursday, I thought it'll be alright.:yes: Saturday dawned a pretty crappy sort of day, was raining when I left home. Weather at Manfeild was considerably better.

F3 practice went horribly wrong, it would appear that the balance shaft was way out of sync with the crank and vibrated so badly was I unable to keep my feet on the pegs. I tried to at least qualify but after a couple of laps one of the mufflers had fallen off, I just thought my ear plugs had fallen out. Pulled into the pits to see SteveyB covering his ears, I looked down to see not only both mufflers missing but they had broken off at the end of the expansion chamber. There must have been some massive vibrations for that to happen. Back to the pits to see if I can remedy the vibration. To cut a long story short I took the vibrator home for repairs, bloody thing.:angry:

Day 2, F3 race 2. Wet wet wet! Having missed the first race and with only 3 practice laps under my belt I was a little cautious on the first couple of laps. Bike is running mint, more power required though. Wheel spray was terrible when following so pull finger. Duncan past me on about lap 2 so maybe I’ll try and stay with him. Caught up to Gavin (I think) and Chris. Duncan got past with no problems, so I needed to get past. Out braked Gavin at Higgins then round the outside of Chris going on to the extended circuit. Duncan by this time had gone, finished 4th in F3. Fastest lap about 2.22.

Posties race 2. Still wet! As I hadn’t qualified on Saturday I had to start off the back and what an eye opener that was.:shit: I’m pretty sure those guys down the back think it’s a Sunday drive, went past about 4 rows of bikes in the first 50 metres. By turn 1 I had caught the leading bunch and followed Stephen Mossman around to the hairpin then he just fucked off. God dam that thing is fast! Traction looked to be an issue though. Tagged on the back of Murray and Mike and reeled in Stevie. Managed to pass all three and gave Stevie a wide berth. They must have held each other up as I was expecting one of them to come flying past. Franz and Ernie had cleared off so home 3rd pre 89 jnr. Best time 2.20

F3 race 3. Still wet! Another half decent start from row 6, tried an inside line to turn 1 but had that plan foiled by a slow starting RGV and a very slippery white line. Basically followed Duncan round again (pasted Chris Ozzy again!) Following was horrific around the extension, couldn’t see jack! Duncan finally made a mistake going into Higgins and I capitalized 2 corners later by stuffing it up the inside. Maintained a gap to the finish and 3rd in F3. Best time 2.18,

Posties race 3. Track now drying, can’t be arsed changing tyres. Wets are just about toast now anyway, might as well destroy them completely, thought they should offer some sort of grip! Started in 29 position on the grid again, and by turn 1 I think I pasted Stevie. The first laps were so hectic I can’t recall what happened, pasted Ernie exiting Higgins which seemed far too easy. Franz wasn’t to far away so why not have a crack at him too. Before I knew it I had come from last on the grid to 1st jnr. This was short lived though, had big moment exiting far hairpin,:shit: rear tyre now poked. All I could do now was circulate. Franz, Murray, Mike and then Stevie went by; bike has to be near vertical before I can give it the berries now. No sign of Ernie so will settle for 3rd jnr home.
Although I missed a couple of races I still had a bloody awesome weekend. Watched some sidecar racing too:gob:
Huge thanks to the Vic Club for another awesome meeting.
And those poor marshals out there in some pretty shithouse weather.
And finally to my wife for breaking into my man cave to bring me my spare exhaust system over.

[roadracingoldfart]

That was a good read , i cant wait till you get the bike on better tyres and have the vibes sorted . I can imagine a few awesome races with you , Steevie and Frenchy entertaining us all . Bring on the fine round you all deserve.
Good effort for the weekend even with all the problems you encountered.

PS; I hope you re-secured the man cave .....

Paul.

[Deano]

I wondered who had lost their end can. Bad luck but good you got it sorted.

[scracha]

Wondered where you were on Saturday.

Sorta got sandwitched behind some lardy black FZR. $hit happens. The first laps were mental. I'm dunno how the hell you make out of corners sometimes as that KR changes lines so much mid-corner. Very scary to pass.



pasted Ernie exiting Higgins which seemed far too easy.

You spooked him and he had a big slide and I had to evade quickly.



Franz wasn’t to far away so why not have a crack at him too. Before I knew it I had come from last on the grid to 1st jnr.

Thought you had. Good stuff. Thanks for holding up Frenchy for me.

Pooftah...to be fair though, gentle throttle control and the KR250 don't seem to mix.

A man cave should be locked up tightly young man.

[neil_cb125t]

old kawakas have a habit of shaking things loose - its even worse when your little donk fire twice as much as mine!!

unlikey times but still better to be racing than reading about it on the web...:-(

[Crasherfromwayback]

Well done mate...always great to see KR1's doing their thing!

Perhaps you shouldn't try and pass next time. Normally I try and take a 125 style line as power is between 9 and 11000 rpm.
I think Ernie went out on the wrong tyres.
I pleased my KR is going to be competive againist your guys 600s.
Man cave is secured and have new hiding place for the key.

The KR is normally smooth as and the crank builder has admitted he didn't see the balance shaft marks on the centre crank drive gear.
It's good for me that you're not racing or I'd be a place further back.

Best you get your leathers back, I am building another one.

Should be good, some close racing at the pointy end of the juniors. Ernie will be the one to beat, that bike of his is a rocket ship.

[roadracingoldfart]

Yer , hes going to need a few weeks to have them re-sized lmfao .:yes::shit::blink:

Be easier to get another set of leathers made!

[scracha]

I pleased my KR is going to be competive against your guys 600s.

It's the weight thing...it gets out the corners very quickly whereas Frenchy and I are slipping and sliding. What are they, 150Kg wet and thats before you ditch all the road gear? Add rider and I think we're about 70Kg heavier. A bit more top end and that thing would be a scary weapon (Like a certain RD350 that's awesome to watch when it makes an appearance). Dunno how you hold onto the thing!

I'm glad there's no rounds at Hampton downs or Taupo.

Gizza shot ...I'm sure I could tell them I've ozzied it and sneak it into the buckets

[eelracing]

Excellent read George and top racing from the back of the posties grid.

Now just to lift my game and try and keep up,gotta be good for smokers allround.

(Is Scracha beginning to see the light?)

[Drew]

Great read man.

Re the starting from the back; the bulk of the guys back there are not watching the lights, they are watching the bikes in front of them. Multiply a quarter second reaction time by the seven or eight rows and there's a huge delay for them getting off the line. When I did it in F3 I nearly rode into a couple of other riders.

You're meant to hold your line when they wave the blue flag at you Drew.

Hahahahahaha 2 strokes are better than ........ hang on a min , the 4 stroke finished and the smocker didnt . I build real bikes , thats 4 stroke bikes .

What did you do Drew , go anti clockwise ????

Yeah lets have a dry round and maybe some more strokers. Hopefully Perry and Leighton will get there shit together for the next round. Will have to get Perry to post up the results so far for the TSR cup!

Pete McDonald, 1.16 on a KR1s in 1990. That's the benchmark fellas. Looking forward to the 2 stroke resurgance. It's actually ALMOST got me motivated to find a good VJ21 for F3/Pre 89 JR duties.

Perry, RGV of course and Leighton on an NSR, let the battle begin!

Would you think that is realistic considering track surface is not as good and this is the winter series?

Nope. But we've all gotta have goals mate :D

You can thank me later.

[White trash]

Saw that but it's got a 22 front end, no good for pre-89. I suppose a 21 front would be pretty cheap though.....

Race your MVX you poofta

I think that's being quite optimistic, I would have thought you be doing it between races

Amazing how fast everyone was back in the days before transponders huh

Yea,Those transponders are marvellous arent they.Doesnt explain the 1.12 lap I apparently did on an RG150 in 07 though????

[White trash]

'S because you're the RG150 guru Billy, thought everyone knew that? And only a 12? Dukie did a 6 on his stock ZX10 on road tyres ya lightweight.......

[Drew]

Amazing how fast everyone was back in the days before transponders huhThey had officials to keep time on the front runners, so it is fairly accurate.

See above , its a goer.

Thats almost acurate lol.

Thats only for the overbored model proddy racers.

Well if you look at your weight , thats possibly the reason you fat bastard.

They were draconian and normally addes a bit at the end , i had a go at lap scoring for a club once and they counted in full seconds and then rounded them up a bit for error.

I have a mate with a Suzuki X7 in the shed , i should make him get it out for a play.

For real? I thought my 22 on old one was shit hot. Got me some work to do I see.

The best tyres money could bludge mate , Yokohama R110 rears and F110 fronts , awesome shit they were. Best on the Metzlers was about 1.21 as they had no cornering ability.
Ahhh the old days were fun. 250ish proddy bikes , 620 proddy bikes (unless you were on a Suzuki , they had bigger piston kits) lol.

Yer but,I heard he had a pillion too help with traction control and I didnt

[roogazza]

The idea was to win a race, not to get a pb. Have you thought that's where you are going wrong ?

Even a moron can hit the stop/start button on a stopwatch at the right time mate. Had a transponder on my 883 when it stopped the clock at 1.19 if that helps ya.

Had a transponder on my RGV when I did a 1.16 as well. Basically never saw KR1's at the pointy end of a 250 Proddie race once the banana arm RGV's arrived. And thats one F@#ken fast MVX!!! Got a dvd at home showing 250 proddie racing from Manfeild back in those days - and it states on there that Eddie Kattenberg on a TZR was the lap record holder at a 1.19.26 - and considering about the first 30 rows of bikes were TZRs, I'm well impressed a MVX did a 19 flat!

Think you might need to get your eyesight (and facts) sorted mate. TZR's were well before KR1's. And when I won the 250 proddie TT race at Manfield in 91...it was against a feild full of banana armed RGV's. Bruce Ainstey, Grant Ramage, Johnny Hepburn and Mike McCutcheon were all armed ('scuse the pun) with them. Dave Cole rode an NSR...and there were no TZR's in sight once Tony Sampson changed to an NSR as well. And for the record...minute 16 flat was the go then.

If you re-read my statement was actually comparing the TZR's and the MVX - not the KR1's.

Ummmm...no. You stated there were no KR1's at the pointy end of a proddie race once banana armed RGV's turned up no?

[ttelp15]

Ummmm...no. You stated there were no KR1's at the pointy end of a proddie race once banana armed RGV's turned up no?

OK - so you read everything 100% literally. I'll take that statement back then - no probs. Yeah, maybe an odd race here or there was won by a KR1 or NSR. But the RGVs won a lot more.

[Crasherfromwayback]

Well I only hung round for a single season, and I think Dave Cole moved classes. So that only really left RGV's behind to play.

[Billy]

You cant compare laptimes from one day to the next let alone 20 years apart,The bikes were new and the front runners at National level were by NO means on standard bikes,Having said that if you fit a small amount of kit parts to a standard 250,You will only see a small improvement and certainly not enough to warrant 3-4 seconds per lap,

Manfeild promotions when run by the Lesters had their own timing system,Dont know what it was or how it worked,But I do know it was good enough for the FIM too approve for WSBK.

Track condition,Anybody that raced through 79-88 will remember there was a huge lump in the middle of turn 2 that restricted the entry to splash therefore making the complete infeild a nightmare,The bump at the entry too Higgins has been there forever likewise the ruts through the Goodyear kink and at turn 1,So how was the track better back then.Ive been riding at Manfeild since it opened in 73 and I see nothing out there now that restricts my laptimes other than ME.

Who gives a rats arse who did the fastest laptime,One fast lap does not win a race as pointed out by Gaz

[nzkr1]

Perry best you put your money were your mouth is and get that RGV on the track, and beat that pesky KR1. Check with Eddie and he will confirm that the KR1 is at least 10 mph faster than the RGV.

[Crasherfromwayback]

KR1's are indeed faster than RGV's. And for the record Billy...only non std things on mine were a trick CDI, and I ran it on av gas pre mixed. Think you'll find the fast RGV's had a shitload more mods than that!

Its getting close George. Hopefully spark it up mid next week. And 10 MPH faster? Hmm - maybe they were a bit faster top end, but 16 kmh???

They sure as shit did,Including forksprings,shocks,control units,close ratio g/boxes,SPheadgaskets and dont forget the Hondas

[Crasherfromwayback]

Yeah the close ratio boxes were a dead giveaway! They'd change three gears coming out of corners to my two! It was easy to tell who was on a rocket anyway. My KR1 ate stockers! Whilst he rode it really well...Dave Coles NSR was 'tuned' to perfection! As far as suspension goes...I didn't even adjust the spring preload. Didn't know what the hell I was doing so thought it better to leave it alone! Did my best to ride around any issues I had.
