Taking a GS1000 to the track, advice needed

[Guest]

Suspension, brakes, and tires are about the only things to be concerned with for track days and novice racing. It can be really that simple at first. Then spend the rest of your money on instruction.

That is great advice. I will add that OP should aim for reliability over all else on the drive train side. Piles of power do you no good if you are sitting in the pits with a broken bike.

...I did order the Sonic 1.1 kg springs, will use them with the MikesXS cartridge emulators.
Just wondering if i should use the standard amount of oil...

Set the oil level to 120mm. The springs come with instructions on how to set the level.
Holler at me anytime you have questions about the fork setup.

excellent, thanks Rich !

thanks Mark, keep the advice coming

i'm trying to do it right... new tires, chain and sprockets, Pingel tap, Koni rear shocks, bearings, Dyna S and Dyna 3 Ohm coils.
Twinpot upgrade : rebuilding calipers and mc's.
Front suspension upgrade : MikesXS cartridge emulatore and Sonic springs, new oil and seals.
Compression is ok, valves lapped, new valve stem seals.
VM28SS carbs rebuilt 'GSR style' with Cycle-O-Rings package inc. carb boots and rings. Will be synced and Dynojet tuned.

Even new wiring : using M-Unit and Compu-Fire.

Would be a shame to leave the old stator in : even though it is still ok the wires to RR are hard.
It may last another 38 years but i feel better with a new one.

I think in the past there was a preference for Rick's but checking The Stator Pages and a dozen or so threads on replacing the stator i get the feeling that preference is not so much there anymore.

People mainly seem to use Rick's (145$), Electrosport (120$), Caltric (35$) and i did not read about any issues with those.
OEM is in the 350$ range

Which one would you guys use (or avoid) ?

I put a functioning used stock stator in my GS1000 with a Honda R/R years ago and 50,000kms later all is still good. I'd say pull the cover and if the stator is not heat damaged swap out the R/R with a series one and be done with it.

Kawasaki ones fit too & usually aren't so toasted for some reason...

With all the changes you are making will you get a chance to road ride it and sort the basics before hitting the track? Trying to learn to track ride while also sorting out your bike is a bad idea. Make sure as much as possible is tested and set up beforehand so you can concentrate on your riding.

definitely, the bike needs to show me it's reliable so i will road test it for at least a week.
Not a quick Italian testdrive but good long rides including lots of twisted roads to get used to it and make changes where needed.

Still waiting for the Compu-Fire to arrive, should have had it sent by air freight.

To get a feel for how the bike runs, i wonder if i can just hook up the
contact points and 3 Ohm Dyna's and take it for a ride.
Stator not connected.
Will that blow the stator ?

Pull the stator out of the sidecover to be sure. It's about a 10min job. A good battery will give you a couple of hours running - without lights and not too many starts...

I am using the same r/r set up, works well. unplugged my stator/lights and had no issues after the reg/rect fried in the middle of no where. Ive also ran with no stator, starter, lights and a moped battery all to save weight. Ran well over 100 miles of track time. Ignitions dont use much juice. Was well tuned and with 1 friend and slight incline 2nd gear push starts were no problem. On the other hand, every bit of advice about keeping it as simple as possible is THEE best advise one could ever have. Find a lonely road and practice braking, find your limits on the street as there will be more traction available on the track due to better grip. Now your getting me going. There are 2 more local track days available before winter....

Great discussion here...
I'm still slowly gathering parts to build a 2-cylinder gs425 502cc WERA Formula 500 road racer or at least track day bike. I will be doing a Rickman CR900 chassis with GS1000-1105cc stroker engine with CR31 carbs, D-Port head, Yoshi cams, etc but...that much power to a street rider canyon carver hotshot turned novice track rider could be very dangerous at first, so the Formula 500 GS425 will be the priority on the track at first.

absolutely. Glad to be standing on the shoulders of giants, excellent advice on this forum !

The throttle works both ways, you know. I did all my track days on my GSXR1000 and it was no issue. I look forward to seeing pics of both your Rickman GS and the GS425, both will make cool vintage track bikes.

Rijko...so did a trackday on the bike ever materialize in 2017?
Seems the weather over the pond might have held out a month or so after last post.
