ESE's works engine tuner

[Buddha#81:Me]

The rush is on for Taupo and not enough time to test Buckets chambers and make a new one for the bike so we have to get the best we can out of an old RS125 pipe which we think is too short.

Attachment 226222

The pipe has been split in the mid section and varying length inserts made for it. With the insert in place the wrap around on the outside is held tightly by hose clamps.

There is also a range of header extensions to go between the header and cylinder. So there are plenty of options for finding the right tuned length and adjusting it at the header or in the mid section, whatever works best.

This is a real Bucket as it has Honda, Kawasaki, Suzuki and Yamaha as well as a few home made parts, in it.

Thats gold, you guys have been testing and devloping all year and now ya rushing to get something going for taupo?

If ya had a FXR you could have won the last three GP's put it in the shed between without any need for development!

seeing as how they have built 2 new bikes and rebuilt another + keepet 2 f5 and a 4th f4 bike going I dont think they have done to bad do you ?




I bet there isn't a standard fxr as reliable and fast as my 2 smoker. 18 h/pat the rear wheel. 5 years and counting, 4 2 hours, 3 taupos , 5 years non stop racing and I have had the engine apart only once (to see how it was going)

if you want a slow booring bike


( good if you can ride but I need the H/P )

My standard FXR engine is having a freshen up after 4500 race km (all at ruapuna, levels, methven, nelson and greymouth street races) thats after Sketchy owned and thrash it. Relaible....i'd say more than........faster we will never know but it wasnt as fast as the ones that won the last three taupo gp's.

I never questioned what Team ESE has achieved this year....just thought the team might have started preparing earlier?

how much earlier should they start ? ( 20th november 2008 )

there has been more than 250hours spent on each of the 2 new bikes this year + Ned kellys bike has had a compleat rebuild
the 2 f5's are still running
then zebras bike needs a tune
a couple of fxr's to run up and play with
a half dosen hours on Speedpros bike
Tz's rg50 to finish
the aprilla 50 to start





you get the point ? there just isn't enough time in the day ( or year )

they spend more time playing with bikes than working and started before getting home from the last TRRS

There is certainly something to be said for FXR's and with any luck they might make it 4 in a row .........

We started in earnest on our new Taupo bikes last March and have been working hard on them all year, I can't believe we have run out of time ....

Looks like I will be dragging an untested bike to the TRRS, still if it all turns to custard there will be plenty of exciting Bucket racing to watch and people to catch up with.

One week to go before Taupo and this is where I am at.

The engine vibrates real bad and I need to re-balance it.

As there is no one universally "correct" balance factor, there is only the one that works in your bike and it has to be found by trial and error.

Engine frame and suspension all affect how much you feel the vibration given off by the crank. The likely range of ballance factors that will work well with a high speed 2-Stroke seems to be in the region of 50% to 65%

Posts on balancing cranks started on Page 70.

In balancing the crankshaft there is only "Reciprocating Mass", "Counter Balance" and the "Balance Factor" which is the relationship between them.

"Counter Balance" = A "Reciprocating Mass" = B and "Balance Factor" = C

Then A = B X C

This formula gives you the Mass (weight) of the Counter Balance if you know the Reciprocating Mass and the Balance Factor you want to use.

This is not new, and Speedpro has already posted hand drawn pictures like this, showing how he did it.

Check out the quote for info on working out ballance factors and how to change them.

Looks like testing in the rain over the weekend will you be splashing around over the weekend?

[TZ350]

No, Family Xmas get together.......... are you ready for Taupo? will the RS be there?

I must have been lucky. The KE125 bottom end with RG400 piston runs smooth as silk. I would be interested to know if the other builders with the same setup have had similar results.
